SF6 Density Relay Calibration Tester

Description

The SF6 gas density relay is an important component used to monitor the change of SF6 gas density in the SF6 switch body during operation. Due to the infrequent action of SF6 gas density relay in field operation, it often has inflexible action, poor contact and other phenomena after a period of time, and some also show that the temperature compensation performance of density relay becomes worse, sudden change of ambient temperature often leads to misoperation of SF6 density relay. Therefore, DL / T596-1996 preventive test code for power equipment stipulates that each SF6 switch user shall regularly calibrate the SF6 gas density relay. RNSFJ SF6 density relay calibrator is developed according to DL / t259-2012: Calibration Specification for SF6 density relay issued by the National Energy Administration.

This tester uses a 7.0-inch color LCD touchscreen for human-computer interaction, making it more convenient to operate. Built-in large-capacity rechargeable lithium battery pack provides long standby time. Equipped with a standard USB interface, historical data can be exported to a USB flash drive through the interface.
In addition to calibrating SF6 density relays, this instrument also has the function of calibrating pressure gauges and density gauges. The instrument can automatically detect abnormal conditions during the measurement process. If pipe leaks, air leaks, or insufficient inlet and outlet air pressure occur, the instrument will automatically stop running and a warning will pop up.
In a closed container, the SF6 gas pressure at a certain temperature can represent the density of SF6 gas. It is customary to use 20°C as the SF6 gas pressure as the standard value. During on-site calibration, the measured pressure value must be converted into its corresponding pressure value at 20°C under different ambient temperatures to judge the performance of the SF6 density relay.
