Description

Technical Field

[0001] The present invention relates to the technical field of high and low voltage power cabinets, in particular to a high and low voltage power cabinet for electric power engineering. Background Art

[0002] High and low voltage power cabinets are equipment for connecting high-voltage or low-voltage cables. High and low voltage power cabinets are used for switching, controlling or protecting the power generation, transmission, distribution, energy conversion and consumption of power systems. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets then transfer to distribution boxes for each power user. The external line of the power cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Indoor high and low voltage power switch cabinets are one of them.

[0003] The patent with the patent announcement number CN220732012U relates to the technical field of high and low voltage power cabinets, specifically a high and low voltage power cabinet for electric power engineering, comprising a cabinet body, two hair dryers fixedly mounted on the bottom of the inner wall of the cabinet body, a ventilation net fixedly mounted on the inner wall of the cabinet body, a controller fixedly mounted on the front of the cabinet door, a placement mechanism provided inside the cabinet body, and a handle fixedly mounted on the front of the cabinet door. The high and low voltage power cabinet for electric power engineering has a placement mechanism provided inside the cabinet body. During assembly, the required electrical components are locked with the threaded holes on the top of the fixed block by screws, and the fixed block is passed through the corresponding assembly hole according to the position where the electrical components need to be installed. At this time, the card block will shrink into the card slot when passing through the assembly hole, and the card block will reset after passing through the assembly hole, thereby fixing the electrical components on the fixed block to the assembly plate, solving the problem that the position of electrical components in high and low voltage power cabinets on the market cannot be adjusted at will.

[0004] In the above patent, a placement mechanism is set inside the cabinet, and the card block will shrink into the card slot when passing through the assembly hole. After passing through the assembly hole, the card block is reset, thereby fixing the electrical components on the fixed block on the assembly plate. However, it is inconvenient to adjust the height when installing the equipment, resulting in the need for other equipment to assist in installation and maintenance. For this reason, a high and low voltage power cabinet for power engineering with a height adjustment function is designed. Summary of the Invention
