Abstract

The invention discloses a portable on-line automatic oil replenishing device for a high-voltage circuit breaker. The portable on-line automatic oil replenishing device comprises an oil replenishing tank. The oil replenishing tank is connected with an oil pump through an oil inlet pipe. An oil outlet of the oil pump is connected with a tee joint. One end of the tee joint is connected with a pressure release valve, and the other end of the tee joint is connected with an oil outlet pipe. The oil outlet pipe is connected with a three-way electromagnetic valve. An outlet A of the three-way electromagnetic valve is connected with an oil replenishing nozzle through a connecting pipeline, and an outlet B of the three-way electromagnetic valve is connected with a vacuum supply pump through a connecting pipeline. The oil pump, the three-way electromagnetic valve and the vacuum supply pump are all connected with a master controller through electric signals. The portable on-line automatic oil replenishing device is convenient to carry, on-line quantitative oil replenishing can be performed, and on-line hydraulic oil degassing can further be conducted, so that oil replenishing work efficiency is greatly improved, pollution and waste are reduced, and field work safety risks are lowered; and the portable on-line automatic oil replenishing device further has the advantages of being easy to realize and high in field utilization rate.

Description

technical field [0001] The invention relates to the technical field of oil replenishment for electric equipment, in particular to a portable online automatic oil replenishment device for a high-voltage circuit breaker. Background technique [0002] High-voltage circuit breakers play two roles in the power system: one is the control function, that is, according to the operation needs of the power system, put a part of the power equipment or lines into or out of operation; the other is the protection function, that is, when the power equipment or lines fail When the relay protection device acts on the circuit breaker, the faulty part is quickly removed from the power system to ensure the normal operation of the non-faulty part of the power system. [0003] The hydraulic operating mechanism is the power source for completing the opening and closing operations of the circuit breaker, and is an important part of the circuit breaker. The hydraulic oil in the hydraulic mechanism p...
