Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage electrical cabinets, in particular to a high-voltage electrical cabinet. Background Art

[0002] High-voltage electrical cabinets are made of steel and are used to protect components. They are generally made of hot-rolled and cold-rolled steel. Cold-rolled steel is softer than hot-rolled steel, making it more suitable for cabinet construction. They are widely used in the chemical industry, environmental protection, power systems, metallurgy, industry, nuclear power, fire safety monitoring, transportation, and other sectors.

[0003] A Chinese invention patent with announcement number CN120165316A discloses a closed outdoor high-voltage electrical cabinet, comprising a closed cabinet body mechanism and a bearing mechanism installed within the closed cabinet body mechanism. A built-in compression spring is connected within the gap between the two outer shells. The slider at the bottom of the wiring slider is then movably installed within the gap between the other two outer shells, while the other end of the built-in compression spring acts on the surface of the slider. When the wires connected to the protector pass through the multiple sets of transverse holes inside the primary and secondary sheaths in sequence, the multiple sets of outer shells fixed in the recessed holes at the top of the pad can cooperate with the horizontal movement of the two beams to provide a bearing force for the multiple wiring sliders to slide laterally. The multiple wiring sliders spaced apart can provide adjustable paths for paralleling multiple strands of the lower outgoing wires of the circuit breaker, paralleling multiple loads of the upper incoming wires of the circuit breaker, and for the incoming and outgoing wires of the circuit breaker, thereby effectively ensuring that the arranged multiple strands of wire will not be compressed and wear against the notches of the cabinet body.
