Product Description

SF6 Gas Switchgear Calibrator Density Relay Verification Instrument SF6 Gas Density Monitor

 

Merchandise Synopsis

The SF6 Gas Density Relay Testing Equipment is a device used to calibrate and verify the accuracy of SF6 gas density relays. It ensures the proper functioning of these relays by accurately measuring and simulating their operating conditions. With precise control over pressure, temperature, and other parameters, it helps ensure the safe and reliable operation of high-voltage electrical equipment. This equipment offers advanced features, intuitive interfaces, and data analysis capabilities for efficient testing and maintenance of SF6 gas density relays, contributing to the overall safety and efficiency of power systems.
 

Rationale

The gas pressure in a closed vessel varies with temperature, and the relative pressure of SF6 at 20°C is usually taken as the standard value. The relative pressure of SF6 at 20ºC is usually taken as the standard value. In the field calibration, the SF6 pressure value measured at a certain ambient temperature should be converted to its equivalent pressure value at 20ºC, so as to judge the performance of the density relay. In the field calibration, the SF6 pressure value measured at a certain ambient temperature should be converted to its equivalent pressure value at 20ºC, so as to judge the performance of the density relay.

Latching Response Calibration Value: Under the ambient temperature, when the SF6 density relay is zero pressure, slowly inflate the SF6 density relay at a certain speed, when the latching relay of SF6 density relay operates, record the pressure value under the current ambient temperature and convert it into the equivalent pressure value at 20ºC, the equivalent pressure value at 20ºC is the latching response value of the SF6 density relay.

Alarm Response Calibration Value: Continue to inflate the SF6 density relay slowly at a certain speed, when the alarm relay of the density relay operates, record the pressure value at the current ambient temperature and convert it to the equivalent pressure value at 20ºC, this equivalent pressure value at 20ºC is the alarm response value of the SF6 density relay.

Alarm value calibration: At ambient temperature, when the pressure inside the SF6 density relay is greater than the alarm response value, slowly deflate it at a certain speed, and when the alarm relay of the SF6 density relay is activated, record the pressure value under the current ambient temperature and convert it into the equivalent pressure value at 20ºC, and the equivalent pressure value at 20 degrees is the alarm value of the SF6 density relay.

Latching value verification: Continue to deflate the SF6 density relay slowly at a certain speed, when the latching relay of the SF6 density relay operates, record the pressure value under the current ambient temperature and convert it to the equivalent pressure value at 20ºC, this equivalent pressure value at 20ºC is the latching value of the SF6 density relay.
