XSL8019 Gas Relay Calibration Instrument Product Introduction

SF₆Switches are widely used high-voltage electrical appliances in power systems, SF₆The reliable operation of switches has become one of the most concerned issues for power supply and consumption departments. SF₆Gas density relay is used to monitor SF during operation₆SF in the switch body₆The performance of important components that affect gas density changes directly affects SF₆Safe operation of switches. SF operating on site₆Due to infrequent operation, gas density relays often exhibit phenomena such as inflexibility and poor contact of contacts after a period of time. Some also experience a decrease in temperature compensation performance of density relays, which often leads to SF when the ambient temperature suddenly changes₆Density relay misoperation. ThereforeDL/T596-2005 "Preventive Test Code for Power Equipment"Regulation: Each SF₆The unit using the switch should regularly check the SF₆Verify the gas density relay. From the actual operation situation, it can be seen that the SF during on-site operation₆Regular calibration of density relays and pressure gauges is also necessary.

XSL8019 gas relay calibrator is an intelligent SF₆Gas density relay calibration instrument. This calibrator adopts high-precision pressure sensors and high-speed A/D converters, combined with a 32-bit high-performance microprocessor, which can be used for various SFs₆The gas density relay is used for performance verification, which can accurately measure the pressure value at the current temperature when the signal is activated, automatically convert the standard pressure at any ambient temperature to 20 ℃, and has printing, storage, and USB transfer functions. At the same time, it can automatically identify faults during the testing process. 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.

XSL8019 gas relay calibrator main functions Product Function

The main function of XSL8019 gas relay calibrator is to measure SF₆The alarm value, lockout value, alarm response value, and lockout response value of the gas density relay can be measured with single or double lockout during the measurement process. At the same time, the instrument has the function of calibrating the normal temperature pressure gauge and the 20 degree pressure gauge.
