Product Description

R40 series transformer gas relay

   R40 series gas relays are mainly used to protect various types of oil-immersed fully sealed transformers. When the transformer is running, gas is generated due to internal faults, and the gas collects in the gas collecting chamber of the gas relay. When the volume of the gas reaches a certain amount, the alarm or trip contact is triggered, and an alarm signal or a trip signal is output, thereby achieving protection of the transformer. purpose.

   Scope of use: (a). Mounting position: Mounted on the top or side wall of the lid. (b). Environmental requirements: -45 ° C ~ +70 ° C; working environment: -45 ° C ~ +120 ° C; (c). Relative humidity: no more than 95% at +20 °C; (d). Degree of protection: IP55; (e). Power frequency withstand voltage: 2000V, 1min; (f). Insulation performance: 2500V, 500MΩ
 

The gas relay is internally composed of a liquid level transfer mechanism and two magnetic switches 1, 2, 3, 4 (or 1, 2, 3, 4, 5, 6), and the switch action transmits an alarm signal or a trip signal through the terminal block. Output.
 

When the transformer is in normal operation, the inside of the gas relay is filled with transformer oil. When there is a fault inside the transformer, the gas generated by the decomposition of the transformer oil collects in the gas collecting chamber of the relay. The air pressure forces the oil level to drop, and the float decreases with the oil level. When the liquid level drops to the alarm setting value (factory setting is 170ml±15ml), the interlocking magnetic switch 1, 2 (or 1, 2, 3) will give an alarm signal. When a serious fault occurs inside the transformer, a large amount of gas will be generated, and the oil level will drop rapidly. When it falls to the trip setting value (factory setting is greater than 230ml ± 15ml), the magnetic switch 3, 4 (or 4, 5, 6) is linked. The action signals a trip. The transformer is tripped from the grid to protect the transformer. (Note: The gas alarm signal volume value and the trip signal setting value can be adjusted according to the user's requirements)
