An internally adjusted insulating oil compensator for oil-containing electrical appliances

Abstract

The invention discloses an internal adjustment type insulating oil compensator for an oily electric appliance. The internal adjustment type insulating oil compensator comprises a case shell, wherein an opening is formed in a surface of the case shell; a circle of fixing surface is arranged at the opening of the case shell; and a radiating channel made of thin steel plates is formed in the case shell. The radiating channel has three layers, and two ends of the radiating channel are communicated with the outside. The thickness of each thin steel plate for making the radiating channel is 0.5mm. The internal adjustment type compensator covers a shell of a capacitor, a transformer or an electric reactor, the problem of oil leakage of the conventional capacitor, the conventional transformer or the conventional electric reactor is solved, corresponding expansion compensation on increase or reduction of the volume of insulating oil due to change of the temperature of oil in the shell of the capacitor, the transformer or the electric reactor is realized, and normal running of power appliances is ensured.

Description

technical field [0001] The invention belongs to the technical field of capacitor equipment, and relates to an internally adjustable insulating oil compensator for oil-containing electrical appliances. Background technique [0002] Oil-containing electrical appliances are generally composed of a core, insulating cooling oil and a shell. The electrical performance of the insulation in the core is closely related to the absolute pressure in the shell. Oil-containing electrical appliances include capacitors, transformers, reactors, etc. [0003] During the use of existing capacitors, transformers, and reactors, due to high internal temperature and volume expansion, the insulating and cooling oil in oil-containing electrical appliances will accumulate from the gap in the shell, causing damage to capacitors, transformers, and reactors. Make electrical appliances can not operate normally. Contents of the invention [0004] The purpose of the present invention is to provide an i...
