High-low voltage prefabricated substation with good protection performance

Abstract

The invention discloses a high-low voltage prefabricated substation with good protection performance. The high-low voltage prefabricated substation comprises a bearing plate, a groove is formed in anupper end of the bearing plate, a first gear is rotatably connected to a bottom in the groove, a first notch is formed in a side wall of one end in the groove, a moving groove is formed in the first notch, and a reset mechanism is arranged in the moving groove. The situation that rain and snow easily enter a box body due to the fact that a side wall of the box body is opened in the past is avoided; the heat dissipation capability can be well ensured; a machine body can be ensured to be in an adaptive working temperature environment; meanwhile, a baffle and the box body can be connected into awhole; the baffle is prevented from rotating at will and can be effectively matched with the box body to isolate the machine body from the external environment, when foreign object collision occurs, the box body and the baffle can prevent the machine body from directly bearing collision, external force is counteracted in a deflection and movement mode, it is guaranteed that the machine body is notdamaged, the normal operation of the machine body is guaranteed, and the service life of the machine body is prolonged.

Description

Technical field [0001] The invention relates to the technical field of prefabricated substations, in particular to a high and low voltage prefabricated substation with good protection performance. Background technique [0002] The prefabricated substation realizes electrical connection through cables or bus bars, and all high and low voltage power distribution devices and transformers are conventional stereotyped products. The prefabricated substation has the advantages of small size, small area, light weight, low cost, and reliability. It is also called "box substation" or "prefabricated substation. [0003] Prefabricated substations generally can be remotely controlled and managed to ensure safe and reliable operation, and have the advantages of convenient maintenance, small on-site installation, short installation and debugging cycle, and movement with load centers, making them suitable for: "residential communities, "Urban public change, bustling downtown, urban residential ar...

AI Technical Summary

Problems solved by technology

[0004] However, because it is generally installed in residential quarters, urban public substations, bustling downtown areas, etc., vehicle collisions may occur. Prefabricated substations are generally fixed directly on the base layer, which cannot well offset the impact force. Some prefabricated substations generally have vents directly on both sides of the box body, which cannot well block the entry of rainwater, which is not conducive to ensuring the safety of equipment operation
