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

[0020] Such as figure 1 As shown, the present invention is an epoxy resin insulating cap, and the insulating cap is a hollow cylinder with one end open. When the insulating cap 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 insulating cap. Fitted into the mounting hole of the main circuit of the high-voltage switchgear, the insulating cap isolates the conductive parts of the main circuit from the outside world, improving the insulation of the high-voltage switchgear to the outside world.

[0021] In a preferred embodiment, the outer cylindrical surface of the open end of the insulating cap is provided with an annular boss 1 . When the insulating cap is matched with the sealing ring of the insulating cap, the insulating cap is completely inserted into the seali...

Abstract

The invention discloses an epoxy resin insulating cap. The epoxy resin insulating cap is characterized in that the insulating cap is a hollow cylinder with an opening in one end. The epoxy resin insulating cap has the beneficial effects as follows: when the insulating cup is used for blocking conductive parts on main circuits of high-voltage switchgear, safety between the conductive parts and other conductors can be protected, interphase short circuit between the main circuits or external discharge can be prevented, the distances between interphase and external conductors can be shortened, andthe manufacturing dimension of the high-voltage switchgear can be reduced; and meanwhile, the conductive parts are sealed by adopting the insulating cap, so that contact with the external air can beeliminated, thereby preventing long-term oxidization of the conductive parts.

Description

technical field [0001] The invention relates to the technical field of electric switchgear accessories, in particular to an epoxy resin insulating cap. Background technique [0002] Epoxy resins generally refer to organic compounds containing two or more epoxy groups in their molecules. Except for a few, their relative molecular weights are not high. The molecular structure of epoxy resin is characterized by active epoxy groups in the molecular chain, and the epoxy groups can be located at the end, middle or ring structure of the molecular chain. Due to the active epoxy groups in the molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble polymers with a three-way network structure. All polymer compounds containing epoxy groups in their 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 surface ...
