Electric arc impact prevention generating device for high-voltage electrical equipment

Abstract

The invention discloses an electric arc impact prevention generating device for high-voltage electrical equipment, and the device comprises a fuse tube; an insulating support is arranged on the right side of the fuse tube, an arc extinguishing cover is fixedly connected to the upper end of the fuse tube, a first connecting piece is fixedly connected to the right side of the fuse tube, and a positioning assembly is arranged between the first connecting piece and the insulating support. The upper end of the first connecting piece is provided with an upper static contact. After the reinforcing assembly, the first connecting piece, the upper static contact and the rainproof cover are installed and connected, the first supporting plate, the second supporting plate and objects on the two sides form a stable triangular structure to support the first connecting piece, so the possibility of breakage possibly occurring for a long time is avoided; all parts on the upper side can be stabilized, so the screw looseness caused by shaking is further reduced; non-slip mats on the first supporting plate and the second supporting plate can enhance attachment of the first supporting plate and the second supporting plate and the first connecting piece, so the supporting effect is enhanced, durability is improved, and the durability of the whole structure is improved.

Description

technical field [0001] The invention relates to the field of electrical equipment protection, and more specifically relates to a device for preventing arc impact generation of high-voltage electrical equipment. Background technique [0002] Drop-out fuse is the most commonly used short-circuit protection switch for branch lines of 10kV distribution lines and distribution transformers. It has the advantages of economy, convenient operation, and strong adaptability to outdoor environments, so it is widely used in 10kV distribution lines and The primary side of the electric transformer is used as a protection to protect the electrical equipment and avoid damage. [0003] The arc chute at the position of the upper static contact and the upper moving contact of the drop-out fuse is generally only fixed by the bolt structure. This fixed connection method makes the bolt structure of the arc chute may loosen after a period of use, resulting in The arc extinguishing cover will rotat...

Problems solved by technology

[0003] The arc chute at the position of the upper static contact and the upper moving contact of the drop-out fuse is generally only fixed by the bolt structure. This fixed connection method makes the bolt structure of the arc chute may loosen after a period of use, resulting in The arc extinguishing cover will rotate, which will affect the arc extinguishing effect; in addition, there is a connecting piece on the upper side of the insulator of the dropout fuse, and holes need to be punched on the surface when pouring, and then the hole is filled with cement so that the connecting piece and the insulator are fixed on the At the same time, although the arc shape can increase the structural strength of the metal connector to a certain extent, it will make the pouring with the insulator weak and easy to loosen
