What are the Differences Between High Voltage Load Switches and Vacuum Circuit Breakers?
What are the Differences Between High Voltage Load Switches and Vacuum Circuit Breakers?
1. The high voltage load switch can be broken with load, with self-arc extinction function, but its breaking capacity is very limited.
2. High voltage disconnecting switch generally can not be broken with load. There is no arc extinguishing cover in structure, but there are also disconnecting switches that can break load.
3. High voltage load switch and high voltage isolation switch, can form an obvious disconnect point, most of the circuit breakers do not have isolation function, there are a few circuit breaker isolation function.
4. High voltage disconnector does not have protection function, high voltage load switch protection is generally fuse protection, only quick break and overcurrent.
5. The breaking capacity of high voltage circuit breaker can be made very high in the manufacturing process. It mainly relies on current transformer and secondary equipment to protect. Can have short circuit protection, overload protection, leakage protection and other functions.
