Problems solved by technology

Due to the large amount of oil in the main transformer, the whole adding process needs to be heated, dissolved and filtered repeatedly, and the procedure is very cumbersome.
Moreover, the addition is often restricted by the weather and the environment, requiring the cooperation of a large number of people, materials, and machines, which is time-consuming and laborious, increasing a lot of operating costs and maintenance costs, and seriously affecting the reliability of the main transformer operation and power supply indicators.

Abstract

The invention discloses an electrified replenishing device for a transformer oil additive. The device comprises an automatic additive dissolving system, an automatic control and monitor system and a vacuum degassing oil injection system. According to the electrified replenishing device for the transformer oil additive disclosed by the invention, the transformer oil additive can be replenished when a primary transformer operates in an electrified state, so that the chemical property and the electric property of the transformer oil are quickly enhanced, and the potential safety hazards of the device caused by degradation of the transformer oil are avoided. In the operating process, the device can be used for replenishing the additive, dewatering, degasing, filtering mechanical impurities and the like at the same time, so that the conventional additive replenishing operating step is greatly simplified.

Description

technical field [0001] The invention relates to a transformer oil additive supplementing device, in particular to a special device suitable for live supplementary transformer oil additive supplementation for main transformers of various voltage levels. Background technique [0002] In recent years, during the operation of the main transformer of the power grid, it was found that the content of additives (T501 antioxidant) in the main transformer oil with a long operating life has decreased year by year due to operation loss, and some have been lower than the standard value (0.15%). During the operation of the main transformer, once the content of the additive (T501 antioxidant) in the oil decreases, it will directly affect the oil quality level of the transformer oil, prompt the rapid deterioration of the transformer oil, and cause a rapid decrease in the chemical and electrical properties of the transformer oil, seriously Shorten the service life of transfo...
