How Much Do You Know About The Function Of Outdoor High-voltage Vertical Fuse Disconnector?

1. When inspecting high and low voltage electrical equipment, use vertical fuse switch disconnector to separate and distinguish the energized and non-energized parts, forming a clear disconnection point, so that the inspection equipment is separated from the large power input from the power system, ensuring the safety of the inspection staff and electrical equipment.
2. nhrt40 vertical fuse switch disconnector and the circuit breaker cooperate with each other to perform the reversing operation to change the operation mode. For the double bus with bypass wiring, when a certain outgoing unit circuit breaker is locked due to other reasons, the bypass circuit breaker can be used to connect the circuit in parallel.
3. For a half-open wiring, when a certain series circuit breaker is locked due to opening and closing, the disconnector can be used to open the loop. For the double bus single segment wiring mode, when the two bus circuit breakers and one of the sectional circuit breakers are locked due to opening and closing, the high-voltage disconnector can be used to disconnect the circuit.
4. The outdoor high-voltage disconnector has a clear disconnection gap, so it is mainly used to isolate the power supply, ensure the safety of the inspection work, and can disconnect the current in the line. In addition, since it does not have a special arc extinguishing device, it cannot be used to cut off the load current when the load is not completely disconnected, and it cannot be used to cut off the short-circuit current.
