SF6 gas density relay calibrator

SF6 gas density relay calibratorSF6 switch is a widely used high-voltage electrical appliance in the power system, and its reliable operation has become one of the most concerned issues for the power supply and consumption departments. SF6 gas density relay is an important component used to monitor the changes in SF6 gas density in the SF6 switch body during operation, and its performance directly affects the safety of SF6 switch operation. The SF6 gas density relay operating on site often experiences inflexibility and poor contact of contacts after a period of time due to infrequent operation. Some density relays may also have poor temperature compensation performance, which can lead to misoperation of SF6 density relays when the ambient temperature suddenly changes. Therefore, DL/T596-2021 "Preventive Testing Regulations for Power Equipment" stipulates that each SF6 switch user unit should regularly verify the SF6 gas density relay. From the actual operating situation, it is also necessary to regularly calibrate SF6 density relays and pressure gauges during on-site operation.

This product is an intelligent oneSF6 gas density relay calibratorThe device. This calibrator uses high-precision pressure sensors and high-speed A/D converters, combined with a 32-bit high-performance microprocessor, to perform performance verification on various SF6 gas density relays. It can accurately measure the pressure value at the current temperature when the signal is activated, automatically convert the standard pressure at 20 ℃ to any ambient temperature, and has printing, storage, and USB conversion functions. At the same time, it can automatically identify faults during the testing process. To cover most density relays on the market, upper and lower pressure values are specially set to make testing more flexible. This product is easy to carry, easy to operate, has high testing accuracy, strong stability, and good reliability, reflecting the "intelligent" characteristics of the instrument.
