Discrete vacuum-pumping transformer oil transfer system

Abstract

The invention relates to a transformer oil transfer system. The transformer oil transfer system comprises a vacuumizing module and a transformer; the vacuumizing module comprises a vacuumizing device, a connecting pipe and a control valve; the connecting pipe comprises a first connecting pipe, one end of the first connecting pipe is communicated with the vacuumizing device in a sealed mode, and the other end of the first connecting pipe is communicated with an oil conservator of the transformer in a sealed mode; the control valve comprises a first control valve which is arranged on the first connecting pipe and used for controlling the vacuumizing device and the oil conservator to be communicated or not. According to the transformer oil transfer system, the transformer and the vacuumizing module are perfectly combined, the oil conservator of the transformer and a box body communicated with the oil conservator of the transformer are made in a negative pressure state by the vacuumizing device, and transformer oil in a radiator is transferred into the oil conservator and the box body; after maintenance, the negative pressure state is stopped, and the transformer oil flows back into the radiator again; in the whole maintenance process, the radiator can be made in a state without oil or a state with little oil by internally transferring the transformer oil, and secondary pollution to the transformer oil is avoided.

Description

technical field [0001] The invention relates to a transformer oil transfer system. Specifically, it is a discrete vacuumized transformer oil transfer system suitable for transferring transformer oil in the process of transformer maintenance. Background technique [0002] The role of the transformer in the power system is to transform the voltage to facilitate the transmission of power. After the voltage is boosted by the step-up transformer, the line loss can be reduced, the economy of power transmission can be improved, and the purpose of long-distance power transmission can be achieved. The step-down transformer can change the high voltage into the various levels of voltage required by the user to meet the needs of different users. The transformer is mainly composed of a box body, an insulating bushing, an oil conservator, a radiator, an iron core and a winding. The transformer box (that is, the oil tank) is filled with transformer oil, and the iron core and winding are...

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that in the prior art, during the maintenance process of the transformer, the internal transformer oil needs to be stored in an external oil tank, which is likely to cause secondary pollution of the transformer oil, thereby providing a transformer without Discrete evacuated transformer oil transfer system that can transfer transformer oil during maintenance using an external oil tank
