Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a modular and easy-to-assemble power distribution cabinet and an assembling method thereof. Background Art

[0002] A power distribution cabinet is a general term for a motor control center. It is a low-voltage power distribution device that is composed of switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment assembled in a closed or semi-enclosed metal cabinet or on a screen according to electrical wiring requirements. It is widely used in industry, commerce, construction, communications, transportation, and other fields, such as factories, shopping malls, office buildings, residential areas, substations, communication base stations, airports, ports, and other places. It provides power distribution and control services for various electrical equipment, controls and protects electrical equipment. When a circuit fails such as overload, short circuit, or leakage, it can quickly cut off the power supply to protect the safety of equipment and personnel. At the same time, it distributes the electrical energy of a circuit of the upper-level distribution equipment to each power unit according to different needs, and transmits the power to the power supply unit. The integrated distribution cabinet usually adopts an integral structural design. In terms of transportation, the integral distribution cabinet is large and heavy, which brings great inconvenience to transportation and lacks flexibility. A large amount of on-site wiring, debugging and fixing work is often required at the installation site. At the same time, the components of the integral distribution cabinet are highly correlated. Once a fault occurs, maintenance is difficult. In order to solve the problems of the above-mentioned integral distribution cabinet, modular and easy-to-assemble distribution cabinets came into being. The distribution cabinet is divided into multiple functional independent modules, and the distribution cabinet is moved to the designated location for assembly. The use of modular distribution cabinets can improve production efficiency, shorten production cycle, reduce transportation costs, simplify installation process and facilitate maintenance.
