Outdoor high-voltage isolation switches are mainly used to provide visible disconnection points in high-voltage systems, achieve electrical isolation, and ensure maintenance safety.
Its product applications can be summarized as follows:
1. Provide obvious disconnection points when repairing electrical equipment. Use isolation switches to reliably isolate the equipment to be repaired from the live parts, forming a clear and visible air gap to ensure the safety of maintenance personnel.
2. Switching operation is used in substations, switch stations, and other places for switching lines, busbars, and other switching operations to change the operating mode.
3. When the equipment is shut down, the isolation voltage should withstand the voltage at both ends of the equipment to prevent accidental or reverse power transmission and protect the safety of equipment and personnel.
The standard equipment for outdoor high-voltage distribution systems is widely used in outdoor substations, switch stations, box transformers, and other places such as 10kV, 35kV, 110kV, and 220kV.
5. Cooperate with circuit breakers to use circuit breakers for breaking current, and isolating switches for isolating voltage. The two work together to ensure safe operation of the circuit.
6. Improving the reliability of system operation has the characteristics of simple structure, high reliability, and strong weather resistance. It is suitable for harsh outdoor environments and ensures the safe and stable operation of the power system.
