Power Supply Side Configuration Of The Stationary Contact Of A High-voltage Disconnector
Date: | Read: 0
In substations, the High Voltage Disconnect Switch circuit is responsible for circuit isolation and equipment maintenance. Standard installation specifications require the stationary contact to be fixed to a bracket and connected to the power supply side via a busbar or cable. The stationary contact of a 35kV outdoor disconnector uses a copper-aluminum transition plate to overlap with the aluminum busbar, and conductive grease needs to be applied to the contact surface to reduce contact resistance. The stationary contact is usually installed behind the operating side, facilitating maintenance personnel to inspect and replace contact wear during power outages.
