Transformer capable of improving maintenance efficiency

Abstract

The invention discloses a transformer capable of improving the maintenance efficiency, and belongs to the field of transformers. The transformer capable of improving the maintenance efficiency comprises a transformer body and a porcelain sleeve installed at the top of the transformer body; a conducting rod is vertically inserted in the porcelain sleeve; a porcelain cap sleeves the conducting rod and is located at the top of the porcelain sleeve; the top of the porcelain cap is also provided with a gasket; the conducting rod is provided with a pressure-bearing structure at the top of the gasket; and the pressure-bearing structure is in threaded connection with the conducting rod. The transformer further comprises a pressing structure which is arranged above the pressure-bearing structure and is in movable sleeve connection with the conducting rod; the pressing structure is pressed and clamped on the pressure-bearing structure; the pressure-bearing structure comprises a base in threaded connection with the conducting rod; a guide groove is formed in the position, close to the top, of the annular face of the base; a protruding guide partition protrusion is arranged in the middle of the guide groove; the time difference of manually winding electric wires one by one and manually taking out fastening screws one by one can be eliminated, time loss is reduced, and the overhaul efficiency is improved.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a transformer capable of improving maintenance efficiency. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the primary winding is supplied with alternating current, alternating magnetic flux is generated, and the alternating magnetic flux induces an alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns. The main function is to transmit electric energy, therefore, the rated capacity is its main parameter. [0003] The measurement and insulation inspection and insp...

Problems solved by technology

[0003] The measurement and insulation inspection and inspection of power transformers is an important item in the transformer test. It has high sensitivity for checking the overall insulation of the transformer. It can effectively detect foreign objects that affect the insulation of the conductive part of the transformer, and the insulation is partially or completely damp and dirty. Severe deterioration of insulating oil, insulation breakdown and severe thermal aging defects. Generally, when performing insulation inspection and maintenance for transformers, the fastening screws of the conductive rods on the transformer porcelain bushings will be unscrewed one by one to free up the test section of the conductive rods. According to the number of porcelain bushings on the transformer, the test wires are wound on the conductive rods one by one, and finally the insulating guide rod is used for current testing. Due to the cumbersome maintenance and testing process of the transformer, the maintenance efficiency is reduced and the operators are laborious.
