Transformer oil leakage on-line plugging assembly and sealing method thereof

Abstract

The present invention discloses a transformer oil leakage online blocking assembly, which comprises an isolating layer and a sealing cover, wherein the isolating layer covers a transformer oil leakage part, the sealing cover covers the isolating layer, a sealed air pressure cavity is formed between the sealing cover and the isolating layer, and a ventilation valve is arranged on the sealing cover. By adopting a method of covering and adhering the isolating layer on a leakage part of a transformer and applying a stress thereon, the pressure inside and outside the transformer can be balanced, thereby the purpose that the transformer oil does not leak in the blocking process is achieved, the problem that the transformer insulating oil leaks during the curing process of an adhesive when the adhesive is adopted for adhering and leaking stoppage is solved, the effective acting time of blocking is prolonged, the operation method is simple, the material is easily obtained, and the blocking is convenient to implement without cutting off power or discharging oil.

Description

technical field [0001] The invention relates to the field of sealing and plugging, in particular to an online plugging component of transformer oil leakage and a sealing method thereof. Background technique [0002] The transformer is one of the most important electrical equipment in the power system, and its operating status directly affects the safety level of the system. Transformer oil leakage occurs from time to time, serious leakage not only reduces the service life and affects its normal operation, but also may cause irreparable and harmful effects on the safe and stable operation of the power grid. At present, adhesives are usually used to plug the leakage of transformer insulating oil. However, this method often has glue flow when applying adhesives, which is inconvenient to operate. If the pressure is high, the insulating oil will leak during the curing process of the adhesive, resulting in poor plugging effect or even failure of the plugging operation. [0003] ...
