High-voltage Disconnect Switches Lack Arc-extinguishing Capability
Date: | Read: 2
The main characteristic of the High Voltage Disconnect Switch is that it has no arc-extinguishing capability and can only break and make circuits under no-load or fault-free conditions. Its contacts are exposed to the air, forming a clear disconnection point, providing a visible isolation state, and it needs to be used in conjunction with a switch with arc-extinguishing function to complete the switching and protection of energized circuits.
