SF6 density relay calibration valve calibration basis: the State grid company attaches great importance to the regular inspection of SF6 gas density relays: DL/T596-1996 "Preventive Test Regulations for Power Equipment" implemented by the Ministry of Power on January 1, 1997 clearly stipulates that SF6 density relays should be periodically checked for a maximum of 2 years; • Article 13.1.6 of the National Energy Administration's 25 Key Requirements for preventing power Production Accidents (National Energy Safety (2014) No. 161) stipulates that the connection between the sulfur hexafluoride density relay and the switchgear body shall meet the requirements of not disassembling the check density relay.
The SF6 density relay calibration valve can be used to verify the SF6 density relay without disassembling, and the SF6 density relay can be verified without power failure. 1. Without disassembling the SF6 density relay, the SF6 density relay can be easily verified or replaced. 2, no need to remove the screw, one person can operate independently, more convenient, labor-saving, time-saving. 3. Completely avoid damage to sealing surface and sealing ring caused by disassembly. 4, more to ensure sealing: more reliable seal with the switch; More reliable operation seal; Operation can also rely on sealing. 5, can be very convenient for SF6 switch micro-water measurement. 6, it can be very convenient to replenish the SF6 switch. 7. Convenient on-site transformation: common tools are OK. 8, after the installation and transformation, it is necessary to ensure sealing and reliable operation. 9, the calibration is convenient, can be completed in a short time, completely reduce the workload.
