Direct-viewing maintenance-free respirator provided oil cup for transformer and using method thereof

Abstract

The invention discloses a direct-viewing maintenance-free respirator with an oil cup for a transformer and a using method of the maintenance-free respirator. The direct-viewing maintenance-free respirator with the oil cup for the transformer comprises the maintenance-free respirator with the oil cup. The maintenance-free respirator with the oil cup is connected with a respirator state observer. The respirator state observer comprises an upper end cover. The upper end cover is provided with an air outlet pipe, the lower end part of the air outlet pipe is provided with a through groove, the upper end cover is connected with a transparent cylinder, the transparent cylinder is connected with the lower end cover, the lower end cover is provided with an air inlet pipe, the air inlet pipe is connected with a metal filter screen, the upper end part of the air inlet pipe is provided with a through groove, an inverted transparent cover is connected between the air inlet pipe and the air outlet pipe and insulating oil is injected into the transparent cylinder. The using method of the maintenance-free respirator comprises the steps that the maintenance-free respirator is connected with the transformer through a flange plate, and the air outlet pipe is connected with an air inlet of the transformer. According to the invention, the working states of the maintenance-free respirator is directly indicated and the working state indicating device is high in reliability, not prone to damage, free of blockage and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of transformer respirator, in particular to an intuitive maintenance-free respirator with an oil-carrying cup for transformers and a use method thereof. Background technique [0002] Transformer respirator, also known as transformer hygroscopic device, the function of transformer respirator is to dehumidify and filter the air entering the transformer, remove moisture and impurities in the air, make the air entering the transformer dry and free of impurities, and prevent transformer oil from being damaged. Under the action of moisture and impurities, the deterioration and aging are accelerated, so as to avoid the reduction of the physical and chemical properties of the transformer oil, such as electric strength, heat dissipation strength and arc suppression performance. In order to ensure that the transformer respirator maintains a stable working condition, it is necessary to monitor the working condition of ...

AI Technical Summary

Problems solved by technology

In general, indicator lights or floating balls are used to monitor transformer respirators, but the working environment of transformers is high temperature and high radiation, and the reliability of electronic products is greatly reduced in this environment. Using indicator lights is easy to damage and difficult to maintain. The light is not intuitive enough; and the use of floating balls is prone to clogging and difficult to maintain

Therefore, the commonly used transformer respirator, the working state indication is not intuitive, and the working state indicating device has low reliability, is easy to be damaged, easy to be blocked, and difficult to maintain
