KGJD-K SF6 Gas Density Relay Calibrator Sulfur Hexafluoride Tester Calibrator ISO9001
Product Introduction
KGJD-K SF6 gas density relay calibrator is an intelligent SF6 gas density relay calibrator. Using embedded microprocessor, the calibrator can check the performance of various SF6 gas density relays, and perform standard conversion of SF6 gas pressure at any ambient temperature. It is mainly used for the production, maintenance and monitoring of SF6 gas products. It is especially suitable for power system, which provides convenience for production, safe operation, pre-test and maintenance of SF6 electrical products.
KGJD- KSF6 gas density relay calibrator absorbs the advanced experience of similar products in China, uses the advanced and accurate mathematical model of the relationship between RTSF6 gas pressure and temperature, and designs a RTSF6 gas density relay calibration equipment according to the needs of field testing. Using embedded microcomputer technology and imported high performance pressure and temperature sensors, the difficulty of calibration of RTSF6 gas density relay is solved. The calibrator simultaneously samples the gas pressure and temperature of the relay under test, and automatically converts it to the standard pressure value at 20ºC, thus completing the dynamic automatic compensation of pressure and temperature. Therefore, the calibrator does not need the constant greenhouse used by the traditional experimental method, and avoids a large amount of SF6 gas waste.
In a sealed container, SF6 gas pressure at a certain temperature can represent SF6 gas density. In order to be unified, it is customary to take the pressure of SF6 gas at 20 ° C as the representative value of its corresponding density. Therefore, SF6 gas density relays use the pressure of SF6 gas at 20 ° C as a scale value. In the field calibration, the measured pressure at different ambient temperatures
