Intelligent oil-immersed transformer oil supplementing method

Abstract

The invention relates to an intelligent oil-immersed transformer oil recharging method. The method comprises the following steps: observing buoyancy borne by a floater of an oil controller, enabling the volume of the floater immersed in transformer oil to change through the principle of communicating vessels and the change of the oil level of the transformer oil in an oil control tank, moving a floating rod up and down at the moment, and sealing and disconnecting an oil recharging hole by an oil plug. The method is easy and convenient to operate, automatic oil supplementing operation of the transformer is achieved, and meanwhile warning is given out when the transformer is abnormal.

Description

technical field [0001] The invention relates to an oil replenishing method for an intelligent oil-immersed transformer, which belongs to the field of transformers. Background technique [0002] To replenish transformer oil into the transformer, the traditional operation method is to directly add oil to the transformer. When performing this operation, power failure is required to replenish oil, so it has a certain impact on people's life and production. In practice, a transformer oil replenishment has been developed. The device, such as the application with the application number 201410724926.5, includes a fuel tank, an internal gear pump is installed in the fuel tank, the oil inlet of the internal gear pump is located at the bottom of the fuel tank and its oil outlet communicates with one end of an oil pipe, and the oil pipe The other end of the internal gear pump extends out of the fuel tank, and the drive shaft of the internal gear pump is connected to one end of a transmi...

[0002]Replenish transformer oil into the transformer. The traditional operation method is to directly add oil to the transformer. When performing this operation, a power outage is required to replenish the oil, so it has caused great harm to people's life and production. Certain influence, in the course of practice, develop a kind of transformer oil replenishing device, such as the application of application number 201410724926.5, including the oil tank, the internal gear pump is installed in the oil tank, the oil inlet of the internal gear pump is located in the oil tank The bottom and its oil outlet communicate with one end of an oil pipe, and the other end of the oil pipe protrudes out of the oil tank. Out of the oil tank and connected with a crank, so that the internal gear pump can be driven by rotating the crank; when in use, first fill up the transformer oil in the oil tank of the oil replenishing device of the present invention, and then remove the end of the oil pipe and extend it into the transformer Then, by manually rotating the handle, the oil outlet of the internal gear pump can be driven to inject oil into the transformer. Of course, oil can be pumped by rotating the handle in the opposite direction. From this, it can be seen that the transformer compensation given above Although the oil device is easy to use, it cannot achieve intelligent oil replenishment operation
