SF6 circuit breaker density relay three-way valve

SF6 circuit breaker density relay three-way valve (WFS-A21-3Ih) is mainly suitable for the electric power industry to meet the requirements of on-line inspection and verification of the density relay without disassembly, which improves the convenience of the verification and air supply of the SF6 density relay without disassembly, thereby It also greatly improves the airtightness of the body.

According to Article 13.1.6 of "The Twenty-Five Requirements of the Energy Administration on Preventing Electric Power Production Accidents" (Guo Neng Security [2014] No. 161): The connection between the density relay and the switchgear body should meet the requirements of not dismantling the school. Density test relay requirements.

Applications

SF6 circuit breaker density relay three-way valve (WFS-A21-3Ih) is mainly suitable for the electric power industry to meet the requirements of on-line inspection and verification of the density relay without disassembly, which improves the convenience of the verification and air supply of the SF6 density relay without disassembly, thereby It also greatly improves the airtightness of the body.
