Analysis Of The Reasons Why High-voltage Disconnect Switches Lack Arc-extinguishing Devices
Date: | Read: 2
Because the High Voltage Disconnect Switch switch lacks an arc-extinguishing device, arcing may occur during power system disconnection operations. The continued presence of arcing can cause significant damage to internal components of the switch and may lead to equipment malfunction or performance degradation. High-voltage disconnect switches are typically used to isolate electrical equipment from the power supply for inspection or maintenance; however, arcing is difficult to avoid when disconnecting the circuit, especially under high voltage and high current conditions.
