Description
Technical field
It the utility model is related to a kind of electric equipment test detection device, more particularly to a kind of dry spring of gas relay
Pipe contact interrupting capacity pilot system.
Background technology
Gas relay operation principle is：Relay is made of open cup, dry-reed contact etc., acts on signal.Relay
It is made of baffle, spring, dry-reed contact etc., acts on tripping.During normal operation, relay is immersed in oil full of oil, open cup,
In floating position, dry-reed contact disconnects.When power transformer interior fault, trouble point locally overheats, and causes neighbouring change
Depressor oil expands, and the air dissolved in oil is expelled out of, and forms bubble rising, while oil and other materials are in electric arc and electric discharge etc.
Effect is lower to decompose and produces gas.When failure is slight, rises and enter relay the gas slowly of discharge, make under pasta
Drop, connects dry-reed contact, sends signal.When power transformer interior fault is serious, strong gas is produced, makes inside transformer
Pressure jump, produces very big oil stream and is impacted to conservator direction, and because oil stream impacts plate washer, plate washer overcomes the resistance of spring, drives
Magnet is moved to dry-reed contact direction and advised, and is connected dry-reed contact, is acted on tripping.
