SF6 density relay calibrator fully automatic, Density meter,
Density meter check KS2001
SF6 switch is a high-voltage appliance widely used in power system,
and the reliable operation of SF6 switch has become one of the most
concerned issues in the power supply department. SF6 gas density
relay is an important component used to monitor SF6 gas density
change in SF6 switch body during operation, its performance
directly affects the safety of SF6 switch operation. SF6 gas
density relay running in the field because of infrequent action,
after a period of time often appear inflexibility, poor contact
contact and other phenomena, and some will appear density relay
temperature compensation performance deteriorates, when the ambient
temperature sudden change often lead to SF6 density relay
misoperation. Therefore, DL/T596 "Preventive Test Procedures for Power Equipment"
stipulates that each SF6 switch user should regularly verify SF6
gas density relays. From the actual operation situation, the SF6 density relay and
pressure gauge in the field operation are also very necessary for
regular calibration
