Operational Application Of High-voltage Disconnect Switches In Power Plants And Substations
Date: | Read: 2
The High Voltage Disconnect Switch is a type of high-voltage switchgear widely used in power plants and substations. In power plants, it works in conjunction with busbars, circuit breakers, and protection devices for circuit disconnection, maintenance isolation, and test connection. In substations, it is often located between incoming and outgoing lines and the main busbar, participating in switching operations, ring network conversion, and operation ticket control. The drive mechanism, contact status, and insulation performance need to be inspected and tested periodically.
