High Voltage Disconnector Transmission Structure And Operating Principle

The conductive part of each phase of hv isolator switch is fixed to the base frame through three support insulators. The middle of each phase contact of high voltage electrical isolator is connected with a pull rod insulator, and the pull rod insulator is connected to the main shaft installed on the base frame. The main shaft is connected to the connecting rod and operating mechanism through a crank arm. The operating mechanism of isolator high voltage is connected to the connecting rod and the auxiliary switch together.
