Problems solved by technology

Previous manufacturing and use experience shows that the high-hanging horizontal oil conservator has disadvantages such as complicated manufacturing, unstable reliability, cumbersome maintenance and installation, strict external live insulation space requirements, and poor safety in the manufacturing and installation process.
The application of high-hanging oil conservator has led to great hidden dangers and defects in oil-immersed electrical equipment in terms of sealing performance, material usage, and maintenance

Abstract

The invention discloses an insulating oil volume compensation device system for an oil immersed electrical device. The insulating oil volume compensation device system comprises an electrical device body filled with insulating oil. An oil volume compensation device is arranged in a low position on the side face of the electrical device and connected with the electrical device through an oil way system. The oil volume compensation device is a volume expansion heat dissipation device. An insulating oil inlet and an insulating oil outlet which are communicated with the oil way system are formed in the volume expansion heat dissipation device. The oil volume compensation device is composed of a plurality of elastic elements and a shell arranged outside the elastic elements. According to the insulating oil volume compensation device system for the oil immersed electrical device, the external structure of the electrical device is greatly simplified, and space is saved; real fuel tank tight welding and sealing can be achieved for the electrical device, and therefore a user does not need to maintain the electrical device, reliability of the electrical device is improved, and manufacturing cost and maintenance cost are saved.

Description

technical field [0001] The invention relates to the field of oil-immersed electric equipment, in particular to an insulating oil volume compensating device system for oil-immersed electric equipment. Background technique [0002] Oil-immersed power equipment such as transformers, reactors, and capacitors all need to consider the volume change of insulating oil as the temperature changes. To solve this problem, an oil volume compensation device is needed. At present, the oil volume devices of all large-capacity power equipment all adopt horizontal high-hanging oil conservator (also known as oil conservator) in order to maintain the highest oil level of the power equipment body and ensure reliable internal insulation. Its structure is as figure 1 As shown, the compensation system is composed of the main body of the power equipment 1, the insulating oil 2, the gas relay 3 and the oil conservator 8 at the high position. When in use, the lowest oil level of the oil conservator ...
