Description

Technical Field

[0001] The invention relates to the technical field of busbar connection, and in particular to a busbar insulation protection device. Background Art

[0002] Busbar is a conductive material used to transmit and distribute electric energy. It is usually made of metals such as copper and aluminum. It plays a vital role in the power system. It can transmit electric energy from the power source to various electrical equipment or loads, such as generators and transformers. Busbar is an indispensable and important part of the power system. It has the characteristics of good conductivity, high mechanical strength, good heat dissipation, and easy installation. It is widely used in power plants, substations, industrial plants, high-rise buildings, rail transportation and other fields.

[0003] Busbar connection is to connect two or more sections of busbars together to achieve power transmission and distribution. When connecting the busbars, it is usually necessary to peel the busbars to expose the metal of the busbars for easy connection. The exposed busbars are prone to leakage, affecting the safety of electricity use. Therefore, the busbars need to be insulated and protected. Therefore, we propose a busbar insulation protection device. Summary of the invention

[0005] A bottom plate, and a protection block symmetrically arranged on the top of the bottom plate;

[0006] A protection mechanism, the protection mechanism having an insulating structure, and used for insulating and protecting the busbar connection;

[0007] The top of the bottom plate is fixedly connected to the bottom of the protection block, the surface of the protection mechanism is fixedly connected to the side of the two protection blocks close to each other, and the two sides of the protection mechanism extend into the inside of the two protection blocks respectively, and the surface of the protection mechanism extending into the inside of the protection block is slidably connected to the inner side surface of the protection block;

[0008] Wherein, the protection mechanism includes:

By setting the telescopic rod, the limit assembly can slide out of the protection block when the busbar is inserted, thereby facilitating the insertion of the busbar. At the same time, before inserting the insulating assembly, the rubber part is fixed, and the insulating assembly can be limited when inserting the insulating assembly to avoid loosening when the insulating assembly fixes and insulates the busbar. After insertion, the exposed parts of the two busbars are located inside the insulating assembly, which can effectively insulate the exposed part of the busbar.

[0014] Furthermore, the limiting assembly includes a limiting cylinder, the outer side surface of the limiting cylinder is slidably connected to the inner side surface of the protection block, and the outer side surface of the limiting cylinder away from the slot plate is fixedly connected to the inner side surface of the plate body, the inner side surface of the limiting cylinder away from the plate body is fixedly connected to the limiting plate, and the limiting plates are evenly distributed along the circumference of the limiting cylinder, and the limiting plate is bent, and one side of the bending of the limiting plate extends out of the end of the limiting cylinder away from the plate body. The plate body moves, driving the limiting cylinder to slide out of the protection block, and then the busbar is inserted into the limiting cylinder. The busbar enters the center of several limit plates, and finally the limit plates clamp the busbar back to the inside of the protection block, and finally the exposed part of the busbar is inserted into the inside of the insulating component. Since the bent side of the limit plate extends to the outside of the limit cylinder, when the limit cylinder is reset, the limit plate and the inner side of the protection block are squeezed, and several limit plates are deformed to clamp the rubber of the busbar, thereby completing the fixed limit at the rubber, and can automatically complete the fixation of the busbar as the limit cylinder slides in and out, and the bending setting of the limit plate can produce a large deformation, so that busbars of different thicknesses can be fixed.

One end of the cone cylinder close to the limiting plate is provided with a deformation groove, and the deformation grooves are evenly distributed along the circumference of the cone cylinder. The position where the deformation groove is provided on the cone cylinder is made of elastic material. After the busbar is inserted into the limiting cylinder, it passes through the cone cylinder and the center of several limiting plates in sequence, and finally enters the interior of the insulating component. The setting of the cone cylinder and its conical inner wall can facilitate the insertion of the busbar, and the surface elasticity setting of the deformation groove provided on the cone cylinder can adapt to busbars of different diameters. The deformation of the cone cylinder can pre-fix the busbar before the limiting plate is fixed to the busbar, thereby achieving a limiting effect and ensuring the stability of the position of the busbar when it is fixed.
