Voltage guiding device, sealing device and method for manufacturing insulating hydrophobic coating layer

Abstract

The invention discloses a voltage guiding device, a sealing device and a method for manufacturing an insulating hydrophobic coating layer. The surface of the voltage guiding device is coated with an insulating hydrophobic coating layer for increasing a surface contact angle. The voltage guiding device comprises a lead, an external mounting flange, an internal mounting flange, an outer side grading shield, and an inner side grading shield. The lead penetrating a wall body of a sealing device is used for guiding a needed voltage into the inside of the sealing device. The external mounting flange is installed at the outer side of the wall body; and a screw hole for fixation is arranged at the connection part of the external mounting flange and the outer side of the wall body, thereby realizing fixed connection between a guiding rod and the wall body. The internal mounting flange is installed at the inner side of the wall body; and a screw hole for fixation is arranged at the connection part of the internal mounting flange and the inner side of the wall body, thereby realizing fixed connection between the guiding rod and the wall body. The outer side grading shield is connected to the external mounting flange detachably in a covering mode; and the inner side grading shield is connected to the internal mounting flange detachably in a covering mode. Therefore, a high voltage can be guided safely to carry out a high-humidity environment voltage test and corona discharging caused by water drops can be prevented effectively.

Description

technical field [0001] The invention relates to the field of electrical technology and the technical field of new electrical materials, in particular to a method for manufacturing a voltage guiding device, a sealing device and an insulating hydrophobic coating. Background technique [0002] In the field of power system transmission and distribution or aerospace, it is inseparable from the study of electrical phenomena in high humidity environments. The electrical phenomena of various electrical equipment will be affected by the electromagnetic environment, and the influence of environmental humidity has attracted much attention. [0003] Taking the voltage experiment in a high humidity environment as an example, the voltage is usually introduced through a high-voltage wall bushing, which is mostly used in large-scale high-humidity environment simulation systems. The wall bushing is mostly used to guide high voltage from one end of the wall to the other. Withstand higher vol...
