Oil conservator capsule damage monitoring device for transformer

Abstract

The invention belongs to the field of mechanical structures, and in particular relates to an oil conservator capsule damage monitoring device for a transformer. The device comprises an oil conservator, a capsule, a connection tube, an oil level indicator and a moisture absorber; the capsule is arranged in the oil conservator; a cavity structure used for filling the oil layer of the transformer is arranged in the oil conservator; one end of the capsule is connected with the oil conservator; the bottom of the other end of the capsule floats on the surface of the oil layer of the transformer; the capsule is connected with the moisture absorber through the connection tube; the moisture absorber is arranged outside the oil conservator; the device comprises a monitoring module; the monitoring module is arranged on the top of the oil conservator; the monitoring module comprises a floater and an alarm structure; the floater is used for inducing pressure change in the oil conservator; the alarm structure is used for giving an alarm; and the floater is arranged in the cavity structure. According to the oil conservator capsule damage monitoring device for the transformer disclosed by the invention, the monitoring device is set and used; therefore, by utilization of the principle that air accumulates at the upper part of the oil conservator to drive the floater to move after the capsule is damaged, the buoyancy forces of the floater in oil and air are different; whether air enters the oil conservator or not is measured, so that whether the capsule is damaged or not is judged; the alarm structure is triggered to given an alarm; and thus, capsule damage monitoring is realized.

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
