Transformer capsule type diaphragm oil storage cabinet

Abstract

The invention discloses a transformer capsule type diaphragm oil storage cabinet which comprises a cabinet body and a capsule bag arranged in the cabinet body. An oil injection port is arranged at the bottom of the cabinet body. The oil injection port is connected with a transformer through an oil delivery pipe. A magnetic oil meter is arranged on the cabinet body. The magnetic oil meter comprises a meter body, a connection rod mechanism and a buoy support point. One end of the connection rod mechanism is in transmission connection with the meter body, the other end of the connection rod mechanism is fixedly connected with the buoy support point arranged on the upper surface of the capsule bag, the middle lower portions at two ends of the capsule body are fixedly connected with the inner wall of the cabinet body, and the bottom of the capsule body is fixedly connected with the bottom of the cabinet body. The oil injection pipe is arranged at the bottom of the capsule bag, the oil injection pipe penetrates through the oil injection port to be connected with the oil delivery pipe, an oil inlet pipe is arranged on the lateral wall of the oil delivery pipe, a row of air discharge holes are arranged on the capsule bag, and an operation hole is arranged above the air discharge holes on the cabinet body. The cabinet is simple and novel in structure, capable of accurately measuring oil level of a transformer and good in sealing performance.

Description

technical field [0001] The invention relates to an oil conservator for a transformer, in particular to a capsule diaphragm oil conservator. Background technique [0002] The power transformer is one of the important electrical equipment in the power system. If an accident occurs, not only the power department itself will suffer a lot, but it will also have a great impact on the production and life of the power users. Therefore, improving its reliability is a must extremely important. As one of the components of the transformer protection device, the oil conservator is mainly used to store transformer oil and balance the internal pressure of the oil conservator, and at the same time isolate the transformer oil from the air to prevent the oxidation of the transformer oil. The transformer oil mainly plays the role of heat dissipation, cooling and insulation maintenance during the operation of the transformer. When the transformer oil is too small, the cooling circulation syste...

Problems solved by technology

This "false oil level" will bring serious consequences to the transformer. As mentioned earlier, accidents such as transformer burnout are prone to occur

At the same time, the tightness of the diaphragm or capsule oil conservator is not ideal, and the air can easily enter the transformer oil from the surroundings, causing a part of oxygen to dissolve in the transformer oil, and the oxygen in the air will make the transformer oil and the fibers soaked in the oil Aging, which affects the performance of the transformer
