Methane gas relay relay Shu Shu Shu relay QJ series QJ-40/50/80 relay ..

Methane gas relay relay Shu Shu Shu relay QJ series QJ-40/50/80 relay Shu transformer relay client reading: Witt Electrical - Transformer parts of the whole country we have only the best suppliers of transformer parts manufacturers promise: We can not guarantee that the product the lowest price, but to ensure the quality of the first! The same price to see quality, please do not ignore the quality of electric power equipment products! Purchasing transformer accessories, electrical Witt to find! Witt electrical relay is the hot gas produced oil flow and hot air generated when promoting the use of the transformer fault relay element, the protective element is a transformer; relay mounted in the gas pipeline and oil conservator of the transformer tank is removed; if charge transformer oil inside the discharge failure occurs, the discharge arc transformer oil decomposition, methane, acetylene, hydrogen, carbon monoxide, carbon dioxide, ethylene, ethane, and other characteristics of the gas, the more serious fault, the greater the amount of gas, the gas generation After rising from inside the transformer to the upper part of the oil pillow in the process, the gas flows through the relay; if the small amount of gas, the gas accumulated in the Buchholz relay, the float drops, the normally open relay contact closure, the role of light gas protection a warning signal; if a large amount of gas, oil and gas through the gas relay fast out, push pull block within the gas relay action, so another group of normally open contact closure, heavy gas directly start relay trips, open the circuit breaker, removal of transformer failures. Purchasing transformer accessories, electrical Witt to find! Of course, immediately after the input transformer energization, heat the oil in the oil dissolved gases rise, and some other gases generated by heat can also make the gas relay malfunction. Technical parameters 1. relay pipe diameter: QJ-40 type is ф40mm 2. relay Operating temperature: -30 ℃ - + 95 ℃ 3. signal contact is gas volume and value factory setting: gas volume range ≥170cm3 factory setting value 170cm3 ± 10% of gas volume and factory 4. trip contact action setting value: gas volume range ≥260cm3 factory setting value 260cm3 ± 10% 5. Contact rated capacity: 220V 0.3A, 110V 0.6A (S ≯5 × 10-3) 6. dielectric strength :( table) procurement transformer accessories, electrical Witt to find! Pilot projects outlet terminals for ground contact terminals between two terminals single frequency pressurized 2000V / 1nim 2000V / 1nim 2000V / 1nim 7. Sealing performance: internal relay full of transformer oil, at room temperature, pressure 200Kpa / 20min, there should be no seepage drain phenomenon. 8. Seismic capacity: When the vibration frequency (Masahiro wave) 4-20 Hz, acceleration of 4g, the relay is not malfunction. (G is the gravitational acceleration) Uses QJ-40 type gas relay is a protective device used sealed transformer, gas relay (hereinafter referred to as the relay) is mounted in sealed transformer tank cover, when the internal transformer failure leaving the transformer oil the decomposition of the gas or oil drops, gas relay contact action to turn the specified control loops, and timely signal or automatically cut power transformer.
