SF6 switch is a high voltage electrical apparatus which is widely used in power system. The reliable operation of the SF6 switch has become one of the most concerned problems in the power supply department. SF6 density relay is used to monitor the operation of the internal SF6 switch SF6 gas density changes of the important parts; its performance directly affects the performance of the SF6 switch operation safety.
1. M 1.Microcomputer to detect and control the density relay, high precision, good repeatability and strong reliability.
2. Large LCD, rotating mouse, easy operation, beautiful interface, all parameters and status at a glance.
3. Automatically finish the conversion between pressure measurement and 20℃, thereby finish the dynamic automatic compensation between pressure and temperature. And display the pressure of the measured environment, the equivalent pressure under 20℃, temperature.
4. All the testing process is automatic, without manual intervention.
5. Printing and intelligent data analysis function.
6. Can store 50 groups of testing results at the same time, data will not lose when power off, historical data can be reviewed and printed at any time.
7. No need thermostatic chamber during the test
8. Equipped with many types of transition joint, can do field test for most of the density relay without disassembly.
9. Will not waste SF6 during the test, with low test cost, without pollution to environment.
10. Can on line modify system clock.
11. Can online modify system pressure on site.
12. Reliable by using advanced imported core components.
