Device for detecting damage of air bag of main transformer oil conservator

Abstract

The invention relates to a device for detecting damage of an air bag of a main transformer oil conservator. The device comprises a box body, a cover body and a bolt assembly, wherein an inflation pipe and an inflation nozzle are arranged in the box body, a connecting flange is arranged at the other end of the inflation pipe, an inflation valve is arranged on the inflation pipe, a pressure gauge is arranged on the inflation valve, and the damage condition of an air bag is judged according to the numerical value change of the pressure gauge. The device has the advantages that the inflation pipe is installed on a main transformer oil conservator breather through the connecting flange on the inflation pipe, the main transformer oil conservator breather is directly connected with the air bag in the oil conservator, the air bag is inflated through the main transformer oil conservator breather, and the damage condition is judged by observing the numerical value change of the pressure gauge on the inflation pipe; therefore, the air bag can be detected without opening the main transformer oil conservator, the detection process is simplified, an accurate basis is provided for judging whether the air bag is intact or not, the problem of air bag breakage is not expanded to a power grid accident, and the whole device is relatively simple in detection process and low in use cost.

Description

technical field [0001] The invention relates to a device for detecting damage to an air bag of a main transformer oil conservator. Background technique [0002] The main transformer oil conservator is an important part of the main transformer. When the volume of transformer oil expands and shrinks with the change of oil temperature, the oil conservator plays the role of oil storage and replenishment. When the oil level of the main transformer oil conservator is abnormal, the current Some inspectors cannot judge whether there is a problem with the airbag, but need to disassemble the oil conservator to check the airbag, which is not only cumbersome but also needs to waste a lot of transformer oil. This device can only be used to detect it when the oil level gauge of the main transformer oil conservator is abnormal. The condition of the airbag cannot be detected in real time. Contents of the invention [0003] The purpose of the present invention is to provide a device for d...
