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.

1、High test accuracy: core components adopt imported components, with high integration degree, high precision, good repeatability and high reliability.
2、Highly intelligent: the calibration process does not need constant greenhouse, and SF6 gas density relay and pressure gauge can be calibrated in any effective temperature range. The pressure and temperature dynamic compensation algorithm is used to automatically complete the pressure measurement and 20℃ equivalent pressure value conversion, and display the pressure at the current temperature and the equivalent pressure at 20℃, effectively solving the difficult problem of field calibration of SF6 gas density relay.
3、Powerful function: it can test one set of alarm signals and two sets of locking signals at the same time, and it has the function of normal temperature pressure gauge and 20 degree pressure gauge.
4、Friendly man-machine interface: large LCD screen and rotating mouse man-machine interface, easy to operate, beautiful interface, all parameters and state at a glance.Automatic completion of the instrument during the test process, no manual intervention is required to avoid cumbersome manual air path adjustment operation.
5、Complete supporting transition joints: sf6 gas density relay calibrator is portable instrument, equipped with a variety of model transition joints, most model switch density relays do not need to be dismantled for on-site verification, is a good choice for the verification of sf6 density relay.
6、Low gas consumption: little gas consumption in the calibration process, no waste of SF6 gas, low test cost, no pollution.
7、Support data storage: the instrument has built-in memory, which can save test results instantly, and has the function of saving data after power failure, which can query and print historical test data at any time.
8、Report printing support: Chinese report printing test results, and intelligent analysis of test results.
9、Clock modification: it has the function of modifying system clock online.
10、U disk storage: support U disk storage test data, read through PC, easy and fast operation.
