At present, in our country's large-scale thermal power plants, due to the original transformer power is relatively low, once can only borrow some of the power transmission in close proximity, after a period of time of development, each large-scale thermal power plants have provoked the upgrading of the transformer, so that you can carry out long-distance transmission of electricity, so that electricity can be used by every household, especially for some remote rural areas, is particularly important. Areas, it is particularly important, but for the assembly and installation of the transformer process, the process is very complex, so there is a need for a lot of ways to carry out strict acceptance, then I made up ah gas acceptance methods and large transformer installation to do a brief introduction.
Large transformer installation
First, the transformer before the installation of the preparatory work:
First of all, we have to add nitrogen inside the transformer for moisture protection, every time we see the transformer in the installation of the position, and can not be directly on Anzhuang up, but to be placed for a period of time, if the moisture is relatively large then it will make the transformer inside the water vapor. Transformer inside into the water vapor, so that the future site safety is extremely unprotected, in order to effectively avoid water vapor, we must inject nitrogen inside the transformer, and real-time tracking and monitoring of the nitrogen lost, if the nitrogen appears to be a small amount of words, it is necessary to replenish the nitrogen inside the transformer.
Secondly, we have to check the size of the transformer, because the transformer size of the university is very large, if my mother did not have a good check on it, it will not be able to install to the center position, and also not be able to fix the transformer well. In addition to this, we have to exclude the atmosphere, the body of the inspection.
Second, the safety of the construction process requirements:
First of all, we have to guard the construction site staff, that is to say, non-professional construction workers are not allowed to enter the construction site, check the transformer staff must be wearing the appropriate work uniforms and safety work shoes, remember not to wear ordinary clothes into the transformer construction site interior, in the construction site Inside also need to be equipped with fire extinguishers, and our construction tools should also be checked by professionals, must ensure that the construction tools can not be faulty, or will be left to the construction estimate of the machine inside the field of staff in addition to the construction of the necessary items can not be equipped with other objects into the construction site.
Secondly, we have to do a good check of the construction of the weather, we must ensure that the construction of the weather ten weeks around the standard environment is clean, and the air humidity can not be too high, the best temperature in the construction of zero degrees Celsius, in addition to the requirements of the weather, we have to check the transformer hanging cover.

Large-scale The working principle of the transformer
The transformer consists of an iron core (or magnetic core) and a coil, which has two or more windings, in which the winding connected to the power supply is called the primary coil, and the rest of the winding is called the secondary coil. It can transform AC voltage, current and impedance. The simplest core transformer consists of a core made of soft magnetic material and two coils of unequal number of turns set on the core.
On the installation of large transformers, I introduced here, we must not underestimate the installation of transformers in preparation for the work, if there is no good preparation, once the problem, the consequences will be unimaginable, I hope that the relevant staff can be handed up to pay attention to up.
