1. Using conditions SF6 relay calibrator
When using the SF6 gas density relay calibrator, it is necessary to understand its use conditions and functions. It can not only deepen our understanding of the instrument, but also help us to the most suitable conditions of the SF6 density relay calibrator.
Ambient temperature: -20℃～60℃
Relative humidity: Less than or equal to 93% (25℃)
2. Functions of the SF6 relay
(1) You need to measure the alarm action and the pressure value at the release of various SF6 gas density relays at any ambient temperature. Also, you should convert it into the corresponding standard pressure value at 20°C to achieve the alarm performance verification of the SF6 gas density relay.
(2) You need to measure the locking action and pressure value at the release of various SF6 gas density relays at any ambient temperature. Also, you should convert it into the corresponding standard pressure value at 20°C to achieve the locking performance verification of the SF6 gas density relay.
(3) If the verified SF6 gas density relay is attached to a pressure gauge or density gauge, the calibrator can also check the accuracy of the pressure gauge or density gauge.
3. How to use the SF6 gas density relay calibrator
The SF6 gas density relay calibrator can measure the alarm action and pressure value of SF6 gas density relays at any ambient temperature.
You can measure the latching action and the pressure value at the release of various SF6 density relays at any ambient temperature. The SF6 gas density relay calibrator is widely used in fields such as the power sector, industrial and mining enterprises. Therefore, how can we use it properly?
(1) When verifying the SF6 gas density relay in the field, you need to disconnect the power supply connected to the density relay to avoid damaging the calibrator.
(2) You need to connect the alarm wire and the locking wire to the signal socket of the density relay respectively based on the test target. Unused alligator clips can be left when performing the single-action signal verification, and please do not contact other SF6 density relay alligator clips.
(3) You need to connect the other end of the equipped signal test line to the navigation signal port on the instrument panel.
(4) You need to connect the gas cylinder to the air inlet on the instrument panel by using the provided connecting gas tube.
(5) You need to connect the SF6 density relay to the measuring port on the instrument panel by using the provided connecting gas pipe and transition joint.
(6) If a gauge calibration operation is required, you need to connect the gauge to be checked to the measurement port on the instrument panel. If a system pressure value correction operation is required, you need to connect a calibrated high-precision pressure gauge to the measurement port on the instrument panel.
(7) You need to turn on the power supply of the SF6 density relay.
(8) You need to open the valve on the cylinder.
(9) The system will display the main interface.
