Description

Technical Field

[0001] The utility model relates to the field of busbars, in particular to a low-voltage cabinet busbar mounting bracket. Background Art

[0002] A busbar is a conductor used to transmit electricity, usually made of conductive materials such as copper or aluminum. It is widely used in power systems of various sizes, including low-voltage, medium-voltage and high-voltage electrical systems. The main function of the busbar is to transmit electrical energy from a power station to various electrical equipment or loads. It can carry large currents while having low resistance and voltage drop to ensure the effective transmission and distribution of electrical energy. In power systems, busbars are usually divided into two types: DC busbars and AC busbars. DC busbars are mainly used in DC transmission systems, while AC busbars are used in AC transmission systems. The design of the busbar takes into account factors such as the current it carries, temperature rise, and short-circuit capability to ensure safe operation and efficient energy consumption of the system.

The utility model does not need to install and fix the tubular busbars one by one, the entire mounting bracket is convenient to install, the installation efficiency is fast, the installation time is short, and it is also convenient to disassemble in the future.

[0004] Moreover, during the installation and removal of the busbar by the existing busbar mounting bracket, the bolts need to be tightened one by one for installation and removal. When a short circuit occurs in the busbar and the busbar needs to be repaired or replaced, the operation becomes cumbersome and time-consuming, resulting in an increased risk of injury to maintenance personnel during the operation and increased safety hazards, thereby increasing the maintenance cycle and maintenance costs, affecting the normal use and operation of the equipment.

[0005] Therefore, it is necessary to provide a new low-voltage cabinet busbar mounting bracket to solve the above technical problems. Utility Model Content
