Oil quantity coordination control device for transformer maintenance

Abstract

The invention discloses an oil quantity coordination control device for transformer maintenance. The device includes a case body; a docking pipe is fixedly inserted into the left side of the case body; the left side of the docking pipe is fixedly connected to a mating flange; and the right end, located in the inner cavity of the case body, of the docking pipe fixedly communicates with a first three-way tube. A flowmeter can perform effective monitoring and control on oil discharge quantity when oil enters the flowmeter, so that convenient maintenance of a transformer can be achieved, maintenance time and maintenance construction period can be shortened, and the operation reliability of the motion of the transformer can be enhanced; the oil discharged by the maintenance can enter an impurity removing mechanism to perform impurity removing, a strong magnet block can adsorb iron and other metal substances in the oil of the transformer, and a multilayer oil-filtering film can isolate and filter the slight impurities in the oil, so that the quality of the oil in the transformer can be optimized, and the oil purity of the transformer can be enhanced; and when the oil is continuously usedwhen back to the transformer after maintenance, the security of the transformer can be increased, and the time efficiency of the using of the oil can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a coordination control device for transformer maintenance oil quantity. Background technique [0002] Most of the power transformers used in the 500kV voltage level are oil-filled transformers. If the transformer fails during operation, it needs to be powered off for maintenance. During maintenance, the oil in the transformer needs to be discharged out of the transformer body. , each time the oil is drained, the transformer oil cannot be completely drained. According to the different maintenance parts of the transformer, there are different requirements for the amount of transformer oil drained. The general principle is to control the amount of oil drained from the transformer. The existing oil-filled transformer The oil discharge cannot be stopped in a timely manner, and the released oil is not processed, but only tested to see if it is qualified, and if it is qualified, it...
