The main difference between isolating switch and high-voltage isolating switch

High-voltage isolating switch, load switch and circuit breaker are all high-voltage electrical equipment used to close and open circuits. They have different tasks in the circuit. Isolating switch can only cut off the line and cut off the power supply when there is no load current. If it is used to cut off the current, it should be a very small no-load current; load switch is only used to cut off the load current, and the short-circuit current should be cut off by the fuse: the circuit breaker is the main equipment for cutting off the load circuit and short-circuit current. Different uses also determine that there are major differences in their structure and type.
