ZJJ-I Series Online Vacuum Oil Filling Machine
ZJJ-I series online vacuum oil filling machine(or named oil recharge machine, vacuum oil recharge machine and transformer oil filling machine) adopts advanced control technology, high quality filters and high efficiency vacuum pump. It has functions of automatic vacuum evacuation and on-load oil filling which can effectively control water content in insulating oil and is widely used for oil filling of electric current transformers or potential transformers (abbreviation as CT, PT) in electrical system for oil level adjustment after periodically taking oil sample and oil testing. It solves the problems of traditional method of artificial oil filling which may cause air absorption of CT/PT coil or illusive oil level caused by residual air. By adopting ZJJ-I machine, there will be no air bubbles formed and no need to stop PT/CT during the oil filling process. The machine is with small size, reliable performance and convenient operation which can greatly reduces the labor intensity and difficulties of work and ensure the safety of the equipment operation. It is widely applied to all types of power substations and other working conditions for oil filling and vacuum evacuation. The ZJJ online vacuum oil filling machine is mainly composed of special connector, oil pump, oil tank, primary filter, electric heater, fine filter, liquid level sensor, temperature sensor, vacuum pump, vacuum gauge, valve group and electric control system.
