High voltage lead-out mechanism of electric power equipment

Abstract

The invention discloses a high-voltage lead-out mechanism of electric equipment. The inner wall of the base is equipped with a sleeve, the inner wall of the sleeve is connected with the outer wall of the base, and the outer wall of the sleeve is equipped with a lower sleeve. The inner wall of the sleeve is connected with the outer wall of the sleeve, and the inner wall of the sleeve is equipped with a conductive rod, and the outer wall of the conductive rod is connected with the inner wall of the sleeve. The high-voltage lead-out mechanism of the power equipment, through the cooperation between the base, the lower sleeve, the upper sleeve and the sleeve frame, under the action of the fixing bolts, the lower sleeve fixes the conductive rod on the base, making the connection of the conductive rod more firm, and then The position of the sliding seat and the adapter plate can be adjusted, thereby overcoming the defects in the design of the bushing body of the high-voltage lead-out mechanism of the traditional power equipment, and the shortcomings of single use function, which improves the service life of the power equipment and reduces the operator's maintenance and replacement. The operation difficulty of the internal components of the power equipment improves the work efficiency and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of electric machinery, in particular to a high-voltage lead-out mechanism of electric equipment. Background technique [0002] In high-voltage test equipment, such as test transformers and non-PD excitation transformers, high-voltage lead-out bushings are required. In the past, high-voltage lead-out bushings used porcelain bushings or capacitor bushings. Although porcelain bushings are low in cost, they are easy to collide. The bushing is broken, causing oil leakage from the bushing, and the capacitive bushing is often expensive, and the process is relatively complicated. In the prior art, for example, the invention patent with the application number 201020506158.3 includes the bushing body, the bushing body connected The flange and the high-voltage conductive rod are drawn out from the bushing body. The bushing body is made of high-temperature-resistant and high-insulation plastic particles at one time. The...

[0002] In high-voltage test equipment, such as test transformers and non-PD excitation transformers, high-voltage lead-out bushings are required. In the past, high-voltage lead-out bushings used porcelain bushings or capacitor bushings. Although porcelain bushings are low in cost, they are easy to collide. The bushing is broken, causing oil leakage from the bushing, and the capacitive bushing is often expensive, and the process is relatively complicated. In the prior art, for example, the invention patent with the application number 201020506158.3 includes the bushing body, the bushing body connected The flange and the high-voltage conductive rod are drawn out from the bushing body. The bushing body is made of high-temperature-resistant and high-insulation plastic particles at one time. The surface inside the bushing body is very smooth, which can avoid partial discharge. The outer surface of the bushing body is set as a skirt structure, which can effectively increase the creepage distance on the surface, and the upper and lower parts of the bushing body are provided with pressure equalizing rings. Although the structure of the invention is simple, there are many shortcomings and defects , in the existing equipment, there are defects in the design of the bushing body, the connection between the bushing body and the pole is stable, and it is easy to cause the shaking and tremor of the pole in the bushing body, and the bushing body can only be connected with one pole The rods are connected and fixed, and the function is single. In view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a high-voltage lead-out mechanism for electric equipment to overcome the above-mentioned defects in the prior art
