Are high-voltage load switches the same as vacuum circuit breakers?

What are the differences between high-voltage load switches and vacuum circuit breakers? This may be a problem that many users are more concerned about. The following the vacuum circuit breaker manufacturer to tell you the difference between the two.

1. The high-voltage load switch can be broken with load and has a self-extinguishing function, but its breaking capacity is very small and limited. Vacuum circuit breakers usually do not have load breaking, and there is no arc extinguishing cover. There is an isolating switch that can break the load, and the structure is relatively simple.
2. Generally, the high-voltage isolating switch cannot be broken with the load. There is no arc extinguisher in the structure, and there are also isolating switches that can break the load, but the structure is different from the load switch, which is relatively simple.
3. Both the high-voltage load switch and the high-voltage isolating switch can form an obvious disconnection point. Most circuit breakers do not have the isolation function, and a few circuit breakers have the isolation function.
4. The high-voltage isolating switch does not have a protection function. The protection of high-voltage load switch is generally protected by a fuse, only quick-break and over-current. Vacuum circuit breakers mainly rely on current transformers and secondary equipment for protection, and have functions such as short-circuit protection, leakage protection, and overload protection.
5. The breaking capacity of the high voltage circuit breaker can be made very high in the manufacturing process. It mainly relies on adding current transformers to cooperate with secondary equipment for protection. It can have short circuit protection, overload protection, leakage protection, and other functions.

A high-voltage load switch is an electrical appliance whose function is between a high-voltage circuit breaker and a high-voltage isolating switch. The high-voltage load switch is often used in series with a high-voltage fuse; it is used to control power transformers. The high-voltage load switch has a simple arc extinguishing device because it can switch a certain load current and overload current. However, it cannot break the short-circuit current, so it is generally used in series with a high-voltage fuse, and the fuse is used for short-circuit protection.

The vacuum circuit breaker can not only cut off or close the no-load current and load current in the high-voltage circuit but also cut off the overload current and short-circuit current through the function of the relay protection device when the system fails,
It has a fairly complete arc extinguishing structure and sufficient breaking capacity and can be divided into oil circuit breaker ((more oil circuit breaker, less oil circuit breaker), sulfur hexafluoride circuit breaker (SF6 circuit breaker), vacuum circuit breaker, Compressed air circuit breakers, etc.
