My country is a country with a large demand for electricity. Up to now, the demand for electricity is not enough, and there is a long-term lack of electricity in some places. The shortage of energy is an important problem in the current development of our country, and the imbalance of development between north-south and east-west has led to the imbalance of power supply. In southern cities, it can be said that there is a huge demand for electricity. Especially in the hot summer, the use of air conditioners has made the already tight electricity even more tight, and many places have been limited by electricity. In recent years, the development of nuclear power plants and dams has eased the tension of electric power. At present, the electric power in southern regions and cities is relatively stable, but there are hidden dangers behind the stability. This requires the use of high-voltage load switches. protected.

This device automatically cuts off the circuit when the current in the circuit is overloaded, and plays the role of protecting the circuit after the circuit is disconnected. The function of this device is the same as that of a high-voltage fuse, but the method itself is different. When a general drop-out fuse is activated, it generates a thermal effect by itself, blows the fuse, and acts as a circuit breaker to protect the circuit board. At present, community houses have fuses, air switches and other circuit protection devices, which are guaranteed for our personal safety.

After reading the above content, I believe that everyone already knows the role of indoor high-voltage vacuum circuit breakers for my country's electricity.
