AC low-voltage power distribution cabinet

Abstract

The invention discloses an AC low-voltage power distribution cabinet, which comprises a power distribution cabinet body and a power distribution cabinet door, and is characterized in that the power distribution cabinet body adopts a universal cabinet and is formed by locally welding cold-formed steel; a solar panel is arranged in the center of the top of the power distribution cabinet body, alarmindicating lamps are arranged at the four corners of the top of the power distribution cabinet body, supporting legs are installed at the four corners of the bottom of the power distribution cabinet body, an interlayer plate is transversely arranged in the power distribution cabinet body, and a heat insulation plate is arranged on the inner wall of the power distribution cabinet body; and when a power distribution cabinet door is closed, an electromagnetic lock and a micro-touch switch are installed at the contact position of the power distribution cabinet door and the power distribution cabinet body, the electromagnetic lock is installed on the inner side of the power distribution cabinet door, and the micro-touch switch is fixed to the power distribution cabinet body and corresponds to the electromagnetic lock. The quality and the precision of the cabinet body are ensured, the universal coefficient is improved, the factory can conveniently realize pre-production, the production and manufacturing period is shortened, and the working efficiency is improved. Moreover, the AC low-voltage power distribution cabinet is good in ventilation and exhaust performance, is stable in structure, facilitates the observation and detection of conditions in the cabinet, and prolongs the service life.

Description

technical field [0001] The invention relates to power equipment, in particular to an AC low-voltage power distribution cabinet. Background technique [0002] The power distribution cabinet is the final equipment of the power distribution system. According to the requirements of the power supply system, the power distribution equipment can be divided into the following three categories: [0003] (1) First-level power distribution equipment, collectively referred to as power distribution centers, which are centrally installed in substations of enterprises and distribute power to lower-level power distribution equipment in different locations; [0004] (2) Secondary power distribution equipment is the general term for power distribution cabinets and motor control centers; [0005] (3) The final power distribution equipment is collectively referred to as the lighting power distribution box. [0006] In some larger final-level power distribution equipment, it is often necessary...

Problems solved by technology

[0008] Most of the power distribution cabinets used in the prior art are fixed and installed with plates through locks, and the integrity is good. However, the power distribution cabinets tend to be partially damaged during use, which leads to inconvenient repairs and poor use effects. poor

[0009] The existing power distribution cabinet is a closed structure, it is difficult for the operator to operate in time, and the bearing strength is relatively weak, which reduces the overall strength of the power distribution cabinet, shortens the service life of the power distribution cabinet, and greatly reduces the reliability of the power distribution cabinet. ;The traditional low-voltage power distribution method mainly realizes power distribution, control, protection, monitoring and other functions through low-voltage switch control cabinets composed of circuit breakers, contactors, thermal relays, fuses, control relays, and various electrical instruments; The capacitor cabinet of this traditional switch cabinet needs to be equipped with a variety of analog pointer instruments, which brings great inconvenience to production, storage and maintenance, and it is mainly manual direct operation, which cannot realize intelligent management, and the safety performance and work efficiency are low.
