Abstract

The invention provides a transformer vacuum oiling device which is characterized in that a crude oil storage tank, an oil filter, a oil filtering and storing tank, a nitrogen tank and a main controller are included, and the transformer vacuum oiling device further comprises a filtered oil storage tank sensing device, a transformer oil tank sensing device, an oil storage tank oil outlet control device, an oil storage tank nitrogen filling control device, a transformer nitrogen filling control device and a vacuum device vacuumizing a transformer oil tank, wherein the sensing devices and the control devices are in signal connection with the main controller, the crude oil storage tank is connected with the oil filter and the filtered oil storage tank in sequence, and the vacuum device vacuumizing the transformer oil tank is directly connected with the transformer oil tank in a sealed mode. By means of the transformer vacuum oiling device, automatic transformer oiling can be achieved, the oiling speed is high, safety and reliability are achieved, on-site oiling can be achieved, moving is convenient, and cost is low. The invention further provides an oiling method, and on-site quick and automatic oiling can be achieved.

Description

technical field [0001] The invention relates to the technical field of transformer oil injection, and more specifically, to a transformer vacuum oil injection equipment and an oil injection method. Background technique [0002] Transformers are one of the main equipment in power plants and substations. The transformer can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage used at all levels to meet the needs of power consumption. The transformer has an oil tank in which insulating oil is used for electrical insulation of the main body of the transformer. If there are bubbles in the insulating oil, it will reduce the insulation level of the transformer and cause a breakdown accident between turns. [0003] In order to improve the insulation level of the transformer, the existing transformer oiling process basically adopts vacuum oiling. With the rapid development of modern technology at this stage...

Problems solved by technology

In addition, due to the very high cost of vacuum oiling equipment, it forms a major development obstacle for developing small and medium-sized transformer manufacturers

At the same time, the vacuum oiling equipment is expensive, bulky, and cannot be moved. It can only be used at the transformer production site. The transformer must complete the oiling process before leaving the factory, which puts forward high requirements for the production, transportation and use of the transformer, which is not conducive to the development of the transformer. develop
