Pillar insulating part for solid cabinet

Technical Field

The invention relates to a post insulator, in particular to a post insulator for a solid cabinet.

Background

Post insulators serve two basic functions in overhead transmission lines, namely supporting the conductors and preventing current from flowing back to ground, and must be guaranteed not to fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulators do not play a significant role and damage the service life and operating life of the entire line. The existing post insulator only plays a role in supporting a wire and preventing current from flowing back to the ground, and can be used only by external accessories (such as a bottom fixing plate, a conducting rod and the like) in the actual use installation and disassembly processes, so that the problems of inconvenience in installation and high production cost exist.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a pillar insulator for a solid cabinet, which solves the problems of the conventional pillar insulator that it only functions to support a wire and prevent current from flowing back to the ground, and is inconvenient to install and high in production cost.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a pillar insulating part for solid cabinet, includes the insulator and seals and arranges in conducting rod in the insulator, the one end of insulator is equipped with binding post I once, and the other end is equipped with binding post II and binding post III once, the insulator adopts epoxy pouring formula structure as an organic whole, and the surface spraying has the aluminium bisque.

The primary wiring terminal I is of a contact type structure, and the primary wiring terminal II and the primary wiring terminal III are of groove type structures.

The primary wiring terminal II is arranged along the axial direction of the conducting rod, and the primary wiring terminal III is arranged along the direction perpendicular to the conducting rod.

And the outer sides of the primary wiring terminal I, the primary wiring terminal II and the primary wiring terminal III are respectively provided with a high-voltage shielding net.

And the end part of the primary wiring terminal III is provided with a mounting flange, and a low-voltage shielding net is arranged in the mounting flange.

The bottom of insulator is equipped with two bases, all is equipped with the installation inserts on each base.

The two bases and the insulator are of an integrated structure, and the bases and the primary wiring terminals III are located on two sides of the insulator.

The invention has the advantages and beneficial effects that:

1. high mechanical strength and convenient installation: the integrated design of the invention ensures that the installation and fixation are firmer and more stable, the support is firmer and more stable, the installation and the disassembly are convenient, corresponding installation accessories are not required to be processed for installation, the aluminum powder is sprayed on the outer surface, and the direct grounding is realized.

2. The interchangeability is good, the commonality is high: the invention adds a conductive path (the size is the same as the primary wiring installation size of the corresponding mutual inductor), and if the mutual inductor needs to be installed, the support column can be detached and directly installed without adjusting the installation size.
