1. Application of Gas Relay used for Oil Immersed Transformer-ERG

 Gas relay is a major protective device to prevent any internal fault in oil filled transformer and oil filled on-load tap changer. Gas relay is mounted at the middle of the connection pipe between the transformer and the oil conservator. When internal fault in transformer and on-load tap changer results in oil decomposition to generate gas or sudden oil surge, the contact of the gas relay will operate to connect the designated control circuit, send a signal or automatically disable the trasformer.

3. Product Characteristics of Gas Relay used for Oil Immersed Transformer-ERG
   1).Pointer adopts quake-proof structure;
   2).Passive device of driven pointer is impossible to get stuck;
   3).Drive shaft and the driven shaft are supported with bearings, move flexible, impossible to get        stuck;
   4).Micro-switch contacts are produced by rotating plate with high reliability;
   5).The length of the support bearing surface under the slurcocks is equal to that of tube connector      of oil flow relay, and        enhanced the strength of the shaft.


4. Use Conditions of Gas Relay used for Oil Immersed Transformer-ERG

   1).Ambient temperature: -30 ℃ ~ + 40 ℃;
   2).Relative humidity: When the air temperature is + 25 ℃, relative humidity shall be less than 90%;
   3).Oil temperature is not higher than 90 ℃;
   4).No severe vibration and bumps around the place;
   5).Oil flow parameters and relay parameters (e.g.: operating characteristics) of transformer cooling    system should be              consistent.

1)Oil flow indicator (called relay for short below) is a device to show oil flow change in the forced oil circulation cooling system of transformer.


2)It is used to monitor the running of oil pump in the force circulation cooling system,for instance, whether the change-direction of oil pump is right.Whether the valve is open and whether the pipeline is blocked. If the oil-flow amount reaches the motion oil flow amount of decreases to be the return oil flow amount.The relay shall be capable of sending off alarm signal.

 

3)The product is the most advanced in the country after modification and has obtained the nation patent with the patent number of 02260487.
