Transformer oil purifier based on high-voltage pulse superimposed direct-current electric field

Abstract

The invention discloses a transformer oil purifier based on a high-voltage pulse superimposed direct-current electric field. The transformer oil purifier comprises a shell, a liquid inlet pipeline is mounted on the upper portion of the shell, and insulating supports are mounted on two sides of one end, extending into the shell, of the liquid inlet pipeline respectively. Filter modules are mounted on the insulating supports respectively, and a partition plate is arranged on one side, close to the inner wall of the shell, of each insulating support. A pole plate is mounted between each partition plate and the inner wall of the shell, a liquid outlet connector is arranged between each partition plate and the corresponding insulating support and positioned on the inner wall of the bottom of the shell, and a liquid outlet pipeline is mounted on each liquid outlet connector. A high-voltage pulse superimposed direct-current electric field generator is mounted above the shell and connected with each pole plate through a cable, and the upper portion of the shell is provided with slotted holes. The transformer oil purifier has advantages that automatic purification of transformer oil is realized, long-time operation of the purifier is realized as well, the filter modules can be replaced conveniently and quickly without influences on normal operations of the purifier, and high efficiency and convenience and quickness in maintenance and replacement are realized.

Description

technical field [0001] The invention relates to the technical field of purifiers, in particular to a transformer oil purifier based on high-voltage pulse superimposed DC electric field. Background technique [0002] Transformer oil is an important insulation and heat dissipation medium in transformers, and plays an important role in the safe operation of transformers. However, impurities will inevitably be mixed in during the production, storage, transportation, and installation of transformer oil, and after long-term operation of the transformer, it will age under the action of electricity, light, heat, and chemical factors, resulting in a large number of impurity particles, including metal particles, oil [0003] Decompose gas, colloid and fiber, etc., which will affect the performance of transformer oil. Traditional methods of purifying transformer oil, such as pressure oil filter filtration, adsorption filtration, and vacuum filtration, have limited purification effect...

Problems solved by technology

Traditional methods of purifying transformer oil, such as pressure oil filter filtration, adsorption filtration, vacuum filtration, etc., have limited purification effects on aging transformer oil, and it is difficult to meet the needs of online purification due to various restrictions

The patent No. 201320666567.3 proposes a transformer oil purifier. Although it solves the problem of generating a high-voltage pulse superimposed DC electric field, it does not point out the specific filtering process of the transformer oil and the structure of the purifier. Therefore, this invention proposes a high-voltage pulse superimposed DC electric field. field transformer oil purifier
