Problems solved by technology

Most of the conductive parts of the main circuit in the existing high-voltage switchgear are laid and installed in the open air, and the conductive parts are not covered and sealed to protect them. Short circuits or discharges to the outside are easy to occur between circuits. The degree of corrosion of parts shortens the service life of high-voltage switchgear

Embodiment

[0024] like Figure 1 to Figure 4 As shown, the present invention is an epoxy resin plastic insulating sealing cover, the sealing cover is a cylinder, one end surface of the sealing cover is provided with a circular blind hole 1, and the other end surface of the sealing cover is provided with a mounting hole 2. When the sealing cover blocks the main circuit of the high-voltage switchgear, it often blocks the connection part of the main circuit of the high-voltage switchgear. The connection part of the main circuit of the high-voltage switchgear is provided with a mounting hole for installing the sealing cover. In the installation hole of the main circuit of the high-voltage switchgear, the sealing cover isolates the conductive parts of the main circuit from the outside, and improves the insulation of the high-voltage switchgear to the outside world. The installation hole 2 is to use professional tools to install the sealing cover, improve the efficiency of assembly, and reduce...

Embodiment approach

[0027] In a preferred embodiment, the sealing cover is an epoxy insulating material. Epoxy resin is an excellent insulating material with high dielectric properties, surface leakage resistance, and arc resistance because its cured epoxy resin system has excellent insulating properties. The cured epoxy resin system has excellent mechanical properties. It has stable structure and excellent mechanical properties; the epoxy resin system after curing of epoxy resin has excellent alkali resistance, acid resistance and solvent resistance, and is suitable for use in severely polluted and severely corrosive places.

[0028] In a preferred embodiment, a threaded hole is provided inside the blind hole of the sealing cover, and the threaded hole is an insert nut 4 . The threaded hole is arranged inside the blind hole of the sealing cover to cooperate with a screw connecting the double-ended screw on the main busbar. The installation efficiency of the sealing cover. The insert nut 4 is n...

Abstract

The invention discloses an epoxy resin plastic insulation sealing cover. The sealing cover is a cylinder. A round blind hole (1) is formed in one end face of the sealing cover, and a mounting hole (2)is formed in the other end face of the sealing cover. The epoxy resin plastic insulation sealing cover has the beneficial effects that the sealing cover is used for blocking electric conduction partson main loops of high-voltage switch equipment; safety between the electric conduction parts and other conductors can be protected; interphase short circuits or outward discharge can be prevented from happening between the main loops; the distance between interphases and the outer conductors can be shortened; the manufacturing size of the high-voltage switch equipment can be reduced; meanwhile, the sealing cover is used for sealing the electric conduction parts; contact with outside air is eradicated; and the electric conduction parts are prevented from being oxidized in long time.

Description

technical field [0001] The invention relates to the technical field of power switchgear accessories, in particular to an epoxy resin plastic insulating sealing cover. Background technique [0002] Epoxy resins generally refer to organic compounds containing two or more epoxy groups in the molecule. Except for a few, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain, and the epoxy groups can be located at the end, middle or cyclic structure of the molecular chain. Due to the active epoxy groups in the molecular structure, they can be cross-linked with various types of curing agents to form insoluble polymers with a three-way network structure. All polymer compounds containing epoxy groups in the molecular structure are collectively referred to as epoxy resins. The cured epoxy resin has good physical and chemical properties, it has excellent bonding strength to the ...
