However, the use of automation technology can help the system react to abnormalities in the work.
3 Current bottlenecks in electrical automation technology
3.1 The phenomenon of serious energy consumption
It is well known that electrical engineering is a particularly energy-consuming technical engineering, because there is no energy support can not be exerted electrical engineering. But in modern life the utilization rate of energy is low, which seriously impedes the long-term development of electrical engineering, so electrical engineering must improve the utilization rate of energy in order to protect the development of electrical automation technology on the basis of energy saving. Throughout the present industrial enterprises in energy conservation is still deficient, whether it is the design or skills lack of energy conservation awareness. This is the engineering designers urgently need to solve the problem.
3.2 Quality Hidden Dangers
At present, there are many enterprises have such a misunderstanding, that is, pay attention to the production results and ignore the quality of the good or bad. The reason for this is also related to the late start of electrical automation in China, because whether it is the management mechanism or the development model is not sound enough, but also makes the development of the electrical industry stagnation. Now with the gradual improvement of people's safety awareness, quality and safety concerns have become the focus again, for an enterprise, the quality of the quality of its survival depends on the elimination, especially quality and safety accidents occur frequently in industrial enterprises, the quality of the equipment as well as the safety of the development of enterprises play a vital role.
3.3 Low efficiency
Productivity development determines the efficiency of enterprise production, but also an important part of the impact on enterprise efficiency. China's electrical engineering and automation technology in the reform and opening up since the go get better results, of course, red do lower efficiency is not negligible. The low efficiency of the work of the main factors are limited by the level of productivity, the use of methods and the scope of application of the limitations. Enterprises in the electrical engineering automation technology whether skilled operation directly affects the economic benefits of enterprises.
3.4 has not yet formed a unified standard of electrical engineering network structure
From the current development situation, electrical engineering and automation technology to achieve a high degree of integration has become an inevitable trend, once there is a breakthrough will directly enhance the industrial productivity and accuracy, but want to get further development, but also need to establish a unified network structure, based on the differences between different enterprises, as well as the various manufacturers. There are differences between different enterprises, as well as various manufacturers in the production of hard and software equipment not standardized program interface, resulting in a lot of information data can not *** enjoy, but also for the development of electrical engineering automation will bring certain negative impact, and ultimately a serious impact on the role of electrical engineering and its automation is difficult to give full play to.
4 Electrical Automation Technology Improvement Strategies
4.1 Focus on energy conservation awareness
To fundamentally reduce the phenomenon of energy loss in electrical engineering automation, we should stand in the quality management point of view to enhance the awareness of energy conservation, and conscious of the quality and energy conservation of the management of the use of unified. Specifically, the key point of energy saving in electrical engineering automation is the management of the transformer, you can choose a lower loss transformer or transformer technology to improve. In addition, it is also necessary for all employees to have a comprehensive understanding of quality, understand that only by constantly improving their technical skills to ensure the quality of the project, and at the same time, in order to save energy also need to have the spirit of innovation, so as to better improve the design of electrical engineering and its automation.
4.2 Further strengthen the quality management
No matter for any kind of industry, the quality is the hard truth, and for the electrical engineering, in order to avoid the occurrence of safety accidents to pay more attention to the quality of the project, so the enterprise should be on a regular basis to the staff on the skills and professional knowledge of the staff to carry out training, and the introduction of professional management personnel, to improve the management from the overall as well as the flexibility of the system. Flexibility. In addition, not only to strengthen the quality management of electrical engineering construction, but also to know its main nature. First of all, the quality of the materials used in the construction should be strictly managed, and secondly, the materials needed for the construction must be professional and technical personnel to purchase, as well as the incoming materials should be arranged for professional management personnel to carry out occasional spot checks, to strictly ensure the quality of construction materials.
4.3 Build a unified and independent platform
Doing a comprehensive survey and research on business users will help to formulate initial goals before designing, in confirming the plan, budget estimates, to keep the project running efficiently, and to maintain the integrity of the work; with the purpose of reducing operating costs, to establish a unified and independent system based on the needs of the end-customer and the business project. Cost pressure is greater because there is no unified operating platform, not strong versatility, this is because electrical engineering and its automation is the enterprise according to their own situation and construction, therefore, the implementation of electrical engineering and its automation also need to be established in a good environment in order to create a unified and independent automation platform.
4.4 Establishment of a unified network architecture for electrical automation
(1) China should be introduced as soon as possible for the electrical engineering and automation industry unified network architecture for the implementation of standards or guidelines, while taking the corresponding legal form of the implementation of the network architecture to assist, so as to ensure that electrical engineering and automation of the production equipment in the national standard led as soon as possible to realize the network architecture. The unification of.
(2) should also be the existing electrical engineering and automation production equipment for the network structure of the upgrading, to avoid the phenomenon of information asymmetry occurs, so that they can make them in the unified network structure under the real realization of the data and information **** enjoy.
5 Conclusion
The vitality of electrical automation technology is the integrity of the structure, the current electrical automation technology in various industries to achieve a wide range of adaptability, and become the main technology of the relevant industries, thus improving the level of research on electrical automation technology, in order to better grasp the core of electrical automation technology.

Electrical engineering student thesis Part 2Abstract :
Reform in the field of electric power further implementation of the background of the operation of the electrical equipment requirements have also improved, to strengthen the safe and stable operation of the electrical equipment, we must start from the actual situation, the faults of the electrical equipment can be effectively solved, which requires the corresponding maintenance technology scientific application. This paper mainly on the common faults and causes of electrical engineering to be analyzed, and then the application of fault repair technology to explore in detail, I hope to be able to protect the normal operation of electrical equipment through this theoretical study to play a role in promoting.
Keywords :
electrical engineering; faults; maintenance technology
electrical engineering equipment failure is relatively common, under the influence of a variety of factors, there are a variety of faults in electrical engineering. Find the cause of the failure problem to target the solution is more important, through the study of common failures in electrical engineering, can provide a theoretical basis for solving the actual failure problem, so as to better protect the good development of electrical engineering.
1 common faults and causes of electrical engineering analysis
The electrical engineering in the different factors under the influence of the existence of different faults, which has a great impact on the normal operation of electrical equipment. In the electrical engineering faults, three-phase power imbalance and the neutral point of poor grounding and damage to a large number of electrical equipment is more prominent, which is also more common fault content. In the design of electrical engineering, specific construction and installation, the more common is the poor contact phenomenon of the neutral point. Some people in the construction did not pay attention to this, thus causing serious losses [1]. For example, in the office when the red, in the use of television sets and tape recorders of electrical equipment a lot of damage, after the inspection found that the line wire 380V normal, and A-phase voltage 280V, in the load of the neutral voltage of 70 V. Mainly is the emergence of three-phase power is not balanced and the neutral point of poor contact caused. Electrical engineering failures, in the relay protection failure is more prominent, mainly the use of materials do not meet the standard, in the quality does not meet the actual requirements. The occurrence of some electrical relay protection faults, mostly by product quality and material factors, there are many faults, making the relay protection device in a dangerous state, which has a great impact on the actual performance of the product. The occurrence of electrical engineering faults, in poor contact and multiple grounding faults are more prominent. The actual operation of the electrical system, with the fault operation is more likely to cause safety hazards. Voltage transformer faults in the design of the factors under the influence, as well as in the management of the lack of scientific, which is more prone to failure, the use of the voltage increases, resulting in circuit load reduction and short-circuit phenomenon. Among the electrical engineering faults, the equipment does not respond after the start button is pressed, the motor does not rotate after the start of the equipment, humming occurs, the motor rotates in a single direction and other faults [2]. All these faults have many effects on the normal operation of the actual electrical equipment. The above electrical failure problems should be analyzed in detail to find targeted methods to deal with them.
2 electrical engineering fault repair technology implementation
The electrical engineering fault repair technology ` application, pay attention to the scientific choice, the author combined with the actual application of the electrical engineering fault repair technology put forward a few measures, as described below:
First, the application of the electrical engineering fault intuition method. Maintenance of electrical engineering faults and judgment has more methods, which is more commonly used intuitive method, mainly on the electrical engineering faults through the visual and olfactory detection judgment, which is more commonly used in the absence of the corresponding detection equipment. In the application of this method, the observer needs to have a wealth of experience, so as to play the role of the intuitive method [3]. Such as the yellowing part of the relay protection device, or smell the smell of burning, you can intuitively determine the equipment failure, which can also provide favorable conditions for the specific fault problem solving.
Second, the application of electrical engineering fault removal method. Electrical engineering faults occur, through the demolition method can also effectively deal with the fault. The application of this method, mainly in series circuits in which the influence of electrical appliances is mutual, in which the electrical appliances are exceeded at will, the other will have no current. In parallel circuits in which the appliances are working independently, there is no connection between the appliances, the removal of one of them will not affect the other appliances. This can play a protective role for the appliances, but also as a way to find faults.
Third, strengthen the safety of electricity settings. To ensure the normal implementation of electrical engineering, we must pay full attention to the electricity setup, construction of temporary electricity is a relatively common problem is that the grounding body buried without standardization. In order to effectively ensure that the failure of the power project to effectively solve the temporary power system using the TN-S power supply system, so that the PE line under normal circumstances no current through, specializing in carrying fault current can effectively protect the device action. Also set up leakage protector, adhere to the principle of three-level protection.
Fourth, the application of electrical engineering fault substitution method. In terms of fault resolution, we must pay full attention to various aspects, the alternative method to be applied scientifically, which is the relay protection device maintenance technology in the use of a wider range of technologies. The microcomputer protection device fault resolution has a positive effect. The application of the alternative method, mainly in the microcomputer protection device failure, maintenance staff should be replaced by the device, the new microcomputer protection device to be applied [4]. In the use of microcomputer devices, the choice of normal plug-in is not the same as the alternative plug-in model to pay full attention to ensure that the role of the device to give full play.
Fifth, the application of electrical engineering fault parameters control method. In the specific fault repair process, through the application of the parameter control method, to solve the relay protection device has a positive effect on the value of the problem fault. Specific application, in the relay value under normal, has a fixed index standard, abnormal values will change, so that the parameters can be found under the control of the cause of the failure problem, so as to target to be solved. Through the application of this method, to solve the electrical engineering faults have a role in promoting.
3 Conclusion
In conclusion, the solution of the fault problem in electrical engineering, we must pay attention to the scientific application of the method. In people's lives, the demand for electricity is also more and more large, the overall quality assurance of electrical engineering is more and more important, through the theoretical study, the fault resolution of electrical engineering can play a positive role in promoting the good development of electrical engineering. It is also hoped that through this theoretical study, the work of the actual staff to play a certain role in enlightenment.
