Ⅰ. SF6 relay calibrator
The main function of SF6 relay is to monitor the change of SF6 gas density in SF6 switch body during operation, so as to provide judgment on whether the operation of SF6 switch is safe.
SF6 relay calibrator is intelligent. SF6 relay calibrator adopts high pressure sensor and high speed A/D converter, combined with high performance microprocessor, which can check the performance of various SF6 relays, can accurately measure the pressure value at the current temperature when the signal is acting, and automatically complete the standard pressure conversion at 20℃ at any ambient temperature. It is easy to carry, simple to opera, with high precision, stability and reliability.
