Transformer Oil Level Adjusting Device

Abstract

The invention relates to the technical field of transformer auxiliary protection device, which is a transformer oil level adjusting device, comprising an oil filling mechanism, an oil tank and a driving mechanism. An oil drain pipe is communicated with the oil tank, a valve is fixedly installed on the oil drain pipe, an air inlet pipe communicating with the inside of the oil tank is fixedly installed on the upper part of the oil tank, and a piston plate which divides the oil filling mechanism into an air chamber and an oil chamber is arranged in the oil filling mechanism. As that structure ofthe invention is reasonable and compact, easy to use, which will fill the tubing, the oil drain pipes are respectively communicated with the oil pillow, Once the actual oil level of the oil pillow deviates from its standard oil level, The valve is opened or the driving mechanism drives the piston plate to move, and the oil drain or oil filling operation is carried out, so as to adjust the actual oil level of the oil sleeper to the standard oil level, so as to ensure that the actual oil level of the oil sleeper runs according to the standard oil level of the oil temperature and oil level curveof the oil sleeper, thereby avoiding damage to the oil sleeper and ensuring the normal operation of the transformer.

Description

technical field [0001] The invention relates to the technical field of transformer auxiliary protection devices, and relates to a transformer oil level regulating device. Background technique [0002] In the power system, in order to meet the technical requirements of the transformer in terms of insulation and heat dissipation, the transformer windings are completely immersed in transformer oil. This kind of transformer is called an oil-immersed power transformer. The volume of the transformer oil contained in the oil-immersed power transformer changes continuously with the operating temperature. This phenomenon is called the respiration of the transformer. The larger the capacity, the more significant the respiration. At present, this kind of transformer is used to compensate the volume change of transformer oil through its oil conservator (commonly known as oil conservator). The capacity compensation of oil conservator is designed under certain operating conditions, that i...

Problems solved by technology

[0003] The invention provides a transformer oil level regulating device, which overcomes the shortcomings of the prior art and can effectively solve the problem that the actual oil level of the oil conservator deviates from the standard oil level when the existing main transformer operates under non-good working conditions. When the degree is large, it is easy to cause irreversible damage to the oil conservator
