- Page 2 Structure of the Gas Relay QJ series of relays are basically in similar structure.the relay’ s core structure is shown in Fig.1, and the relay’ supper core consists of gas lock 1,gas lock nut 2,probe 3, blocking 4, snap ring(float)5, weights drop 6, guard board7, magnet 8, connecting terminal9, spring 10, regulating rod11, and dry reed contact12, forming a flow device that acts on tripping.
- Page 3 position upward as shown in Fig．1．Gas produced by the transformer oil decomposed gathers in upper gas chamber of the relay and forces the oil surface to reduce， snap ring 5 reduces to a certain position together with it， and magnet 8 thereon makes dry reed contact 12 suck to connect with the signal circuit to give alarm signal in the case of slight circuit to give alarm signal.In the case of serious failure inside the transrormer the pressure in the oil tank rises instantaneously,oil surging occurs and impulses guard board7,and magnet 8 thereon makes sry reed contace 12 suck to connect with the tripping circuit to give alarm signal and cut off the teansformer.

- Page 5 Fig.4-3 QJ13 8.2 Debugging QJ series of relays is an important protective device of oil-immersed transformer so there are special provisions stated for an operational unit, for example it may be only brought into service after an inspection department’s debugging, examination, and issuing cofirming documentation, and accordingly works on debugging and oil speed examination should be done according to pertinent regulations.
- Page 6 opened and closed reliably. 8.5.2. To pump gas in from nozzle 1 may cheek action reliability of the “signal” contact. 8.5.3.Take down the probe cover and press probe 2 to check action reliability of the “tripping” contact. 8.5.4 To collect gas sample in service, take down the gas lock dust cover at first, then insert the gas Sample rubber tube in the air nozzle,unscrew the gas lock nut, and the gas sample may be filled in the bottle.
