Structure and working principle of 420kV 5000A HV Disconnect Switch Break Isolator Double Side 3 Phase Disconnect
Earth switch(see the right picture),the movement is by CJ -3 institutions operating lever to earth switch through a link after the conversion, driving a four-link active grounding arm rotation, due to the active arm and door type bracket and earthing pipe is composed according to the design requirements special four-link system, thus ensuring the earth switch in the closing process, the first rotary motion, near the closing position, linear motion upward, insert static inner contact, opening and vice versa.
