Environment-friendly grounding switch with gas arc-extinguishing medium

Abstract

The application discloses an environment-friendly grounding switch with a gas arc-extinguishing medium, which comprises a grounding transmission spring mechanism, a transmission box assembly, a shell support sealing system, a grounding switch moving side assembly and a grounding switch static side conductor assembly; the grounding transmission spring mechanism is in driving connection with the grounding switch moving side assembly through the transmission box assembly; the grounding switch moving side assembly and the grounding switch static side conductor assembly are correspondingly arranged in the shell; the shell support sealing system provides support, sealing and gas chamber environment for the whole; the built-in air cylinder and the piston of the grounding switch moving side assembly form a gas blowing structure, and forced gas blowing auxiliary arc extinguishing is formed during opening. Compared with the prior art, the environment-friendly grounding switch has the advantages that the design structure is convenient to operate and use, and clean dry air or mixed gas arc-extinguishing medium with different proportions of N2 and O2 can be used.
