Oil conservator capsule damage monitoring device for transformer

Abstract

The invention belongs to the field of mechanical structures, and more specifically relates to a capsule damage monitoring device for an oil storage tank for a transformer. The device includes an oil storage tank, a capsule, a joint pipe, an oil level gauge and a moisture absorber. In the cabinet, the inside of the oil conservator is provided with a cavity structure for filling the transformer oil layer; one end of the capsule is connected to the oil conservator, and the bottom of the other end floats on the surface of the transformer oil layer; connected, the moisture absorber is arranged on the outside of the oil conservator; the device includes a monitoring module, the monitoring module is arranged on the top of the oil conservator, and the monitoring module includes a float for sensing pressure changes in the oil conservator and a float for the float In the alarm structure for issuing an alarm, the float is arranged in the cavity structure. The present invention uses a monitoring device so that the capsule breakage monitoring device of the oil conservator uses the principle that after the capsule is damaged, air accumulates on the upper part of the oil conservator and drives the movement of the float. The buoyancy of the float in the oil and in the air is different to measure Whether the oil tank has air intake is used to judge whether the capsule is damaged, and the alarm structure is triggered to send a signal to realize the monitoring of capsule damage.

Description

technical field [0001] The invention belongs to the field of mechanical structures, and more specifically relates to a capsule damage monitoring device for an oil conservator used in a transformer. Background technique [0002] Transformer oil conservator capsules are widely used in power system transformers. Its function is to isolate the contact between transformer oil and air, prevent oxygen and moisture in the air from immersing in the oil, and prevent oxygen aging or deterioration, resistivity reduction, and dielectric loss of transformer oil. Increase, protect the transformer from the erosion of harmful components, and prolong the service life. [0003] During the production, transportation, installation and operation of transformer oil conservator capsules, due to various reasons, there are cases of damage and air leakage. When the capsule is damaged, it will lose the function of isolating the contact between the transformer oil and the air. The transformer oil will ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned technologies, and provide a monitoring device for capsule damage of oil conservator for transformers. By setting up the monitoring device, it can detect whether the capsule oil conservator is damaged, and deal with the defects in time, thus avoiding the transformer oil from being exposed to sunlight. Irradiation aging and deterioration, reducing the sealing surface, solved the problem that the fully-sealed capsule oil conservator adopts an all-metal structure and cannot directly observe the damage and air intake of the capsule
