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.The high performance single chip microcomputer is used to detect and control the density relay, and the integration degree is high. It is mechanical and electrical integration design, high precision, good repeatability, high reliability.
2.Configuration of a monochrome LCD screen and the rotation of the switch, the operation is simple, beautiful interface, all parameters and status at a glance.
3.The pressure and temperature are automatically compensated by the automatic pressure measurement and the 20 ºC value conversion. And display the measured ambient temperature, pressure, temperature of 20 degrees Celsius, the ambient temperature, etc. It solves the problem of SF6 gas density relay field calibration difficult thoroughly.
4.All the testing process is automatically controlled by the single chip microcomputer, without manual intervention.
