Transformer breather

Abstract

The invention relates to the technical field of transformer breathing device, and provides a transformer breather. The transformer breather comprises a flange plate, a breather top cover, a connection rod, a breather shell, a transparent bottom cover and an oil cup, wherein the flange plate is integratedly connected with the breather top cover, a feeding hole is formed in the breather top cover, a detachable plug is arranged on the feeding hole, the breather shell is fixedly installed with the breather top cover, a horizontal baffle plate is arranged at a lower end of the breather shell, a sleeve is sleeved at an outer edge of the horizontal baffle plate, a breathing sleeve is fixedly arranged at a bottom part of the horizontal baffle plate, an isolation layer mesh wraps a bottom part of the breathing sleeve, a round hole is formed in a middle part of the isolation layer mesh, the isolation layer mesh is detachably fixed on the breathing sleeve along the circumference, and the oil cup is fixedly arranged on an inner wall of a lower part of the sleeve. The transformer breather is reasonable and compact in structure and is not needed to be integratedly disassembled by employing a buckle structure, the silica gel replacement time is effectively shortened, the heavy gas protection withdraw time of a main transformer is reduced, and the safety running condition of the main transformer is improved.

Description

technical field [0001] The invention relates to the technical field of main transformer breathing apparatus, and is a transformer breathing apparatus. Background technique [0002] The temperature of the transformer will change at any time during operation, causing the oil level inside the transformer to increase or decrease. The oil conservator is a semi-closed oil conservator, so that the internal pressure of the transformer can be maintained due to the increase or decrease of the oil level. Therefore, in order to delay the deterioration speed of the transformer oil and prevent the air from polluting the insulating oil, the oil Install a respirator on the expiratory channel. The respirator is also called a silica gel tank. The transformer breathes through the silica gel, and then is filtered through the oil in the oil cup at the bottom of the respirator to ensure the drying of the air. [0003] With the advancement of operation and maintenance integration and unattended ...
