Today we recommend the fuse type knife switch is a special product, then what is the fuse type knife switch? Fuse type knife switch acquisition and selection process of the manufacturer's scale technology analysis and where to start to compare and consider it? Through the following examples, we can learn about these factors, which can also be found in the so-called fuse-type knife switch is also based on the current exceeds the specified value of a certain period of time, as well as their own heat, making the solvent melting, so that the circuit is disconnected a type of protection switch.
A, fuse type knife switch is what
Fuse type disconnect switch is based on the current exceeds the specified value of a certain period of time, in order to produce its own heat to make the melt, so as to make the circuit disconnect the principle of a current protector.
The fuse-type disconnecting switch needs to satisfy the following three points:
1. Protection of the switch through the use of fuses
2. A disconnecting switch that is capable of switching on, carrying and breaking currents under normal circuit conditions (including specified overloads) and carrying currents under specified abnormal circuit conditions (such as short circuits) for a specified time
3. A disconnecting switch that is capable of providing safe isolation of a Circuit can provide safe isolation, when in the position of breaking to ensure that the circuit is open and ensure the safety of work
Two, manufacturers recommended
1, Henan Chenhao Electric Co., Ltd. is located in the north of the Yellow River, the Taihang hinterland, the Central Plains urban agglomeration of the core area of the city's important cities in Xinxiang; and the provincial capital of Zhengzhou, Kaifeng, the ancient capital of the river, the economic, cultural and transportation center of north Henan, and the city's economic, cultural and transportation center. It is the economic, cultural and transportation center of northern Henan, a national transportation hub city, only 50 minutes away from Xinzheng International Airport, with very convenient transportation.
Since its inception, the company based on the reverence for science, the love of professionalism, the rigorous attitude towards work; scientific theory and practice combined, through unremitting efforts, research and development of a series of high-low-voltage reactive power compensation controllers, intelligent capacitors, composite switches, and other high-precision end of the electrical products.

2. Yueqing Xifan Electric Co., Ltd. specializes in the production of various kinds of high- and low-voltage reactor, series reactor, filter reactor, single/three-phase inlet reactor, three-phase output reactor, DC filter reactor, current-limiting reactor, starter reactor, adjustable-core reactor, inductors, reactive power compensation controllers, contactors, intelligent composite switches, and similar products manufacturers. and similar products. Xishang Electric takes honest service as its purpose.
3, Zhejiang Liujing Rectifier Co., Ltd. is a professional commitment to power semiconductor devices, anti-reverse diode production and research and development of enterprises, is a professional photovoltaic anti-reverse diode production enterprises, the enterprise since its inception, always adhere to the good faith for this, the concept of sustainable management, always focusing on the rectifier, photovoltaic anti-reverse diode, power semiconductor industry, after many years of development, is now enterprises have been Developed into a comprehensive enterprise integrating product research and development, manufacturing, commerce, import and export of goods and technology and network sales, it is one of the professional power semiconductor/anti-reverse diode manufacturers and exporters in China. The enterprise strictly according to the national standard production, the implementation of CQC?ISO9001:2008 standard, the enterprise has passed the?IQNET?CQC?ISO9001:2008?CE?SGS?ROHS?TUV and other certificates, mastered the core technology of photovoltaic diode, and has a national patent. Enterprises mainly produce: photovoltaic anti-reverse diode, anti-reverse diode, converter box anti-reverse diode, DC cabinet anti-reverse diode, inverter anti-reverse diode, solar anti-reverse diode, etc., single-channel photovoltaic anti-reverse diode module, dual-channel **** yin photovoltaic anti-reverse diode module, dual-channel **** yang anti-reverse diode module and so on the whole series of anti-reverse diode products, for the solar energy customers to provide convergence box, DC cabinet, inverter Anti-reverse diode design services; ordinary rectifier, fast rectifier, ordinary thyristor, bi-directional thyristor, fast thyristor, high-frequency thyristor, bridge rectifier, power semiconductor module, Schottky module, ultra-fast recovery diode, welding machine special module, solid state relay, solid state regulator, profile heat sinks and other full range of power semiconductor products.
Through the above example and description of the comparison, we can learn and other can play a role in controlling the ordinary switch is not the same, the so-called fuse-type knife switch, as the name suggests, is a protection tool, they can be based on the current exceeds the specified value of a period of time after the heat generated by itself, making the container itself melted, thus helping to disconnect the circuit, to prevent the further burial of the Additional fire hazards and further casualties and property damage, you can understand through the above and purchase options.
