Product Introduction

SF6 switch is a widely used high voltage electrical appliance in the power system. SF6 gas density relay is an important element used to monitor the variation of SF6 gas density in the SF6 switch body during operation. Its performance directly affects the operation safety of SF6 switch.Due to the infrequent operation of SF6 gas density relay in the field, it is often found that the operation is not flexible and the contact contact is not good after a period of time, and some of the temperature compensation performance of the density relay becomes worse. When the ambient temperature changes suddenly, the SF6 density relay often misoperates.Therefore, DL/T596-2005 "precautionary test regulations for power equipment" stipulates that each SF6 switch user should verify SF6 gas density relay regularly.From the perspective of actual operation, it is necessary to carry out regular calibration of SF6 density relay and pressure gauge in field operation.

The check pressure sensor with high precision and high speed A/D converter, combining with the 32 bit high performance microprocessor can check the performance of A variety of SF6 gas density relay, can accurately measure the movement of the signal when the current temperature pressure value, arbitrary automatically when the environment temperature of 20 ℃ conversion standard pressure, and have A print, store, and U disk offload function, at the same time, the fault in the process of automatic identification test.Sf6 gas density relay calibrator is convenient to carry, simple to operate, high test accuracy, strong stability and good reliability, which reflects the characteristics of "intelligent" instrument.
