Description

Technical Field

[0001] The utility model relates to the technical field of transformer substation auxiliary equipment, in particular to a novel transformer substation cable trough box. Background Art

[0002] There are many internal lines in the substation, which are mainly routed through trough boxes. Cable trough boxes, as important carriers for laying cables in substations, are an indispensable tool for substation cable construction.

[0003] In addition, traditional cable trough boxes are generally made of stainless steel. Manufacturers transport trough boxes of fixed lengths to the substation construction site, and on-site construction personnel weld them into the required length as needed. This method uses welding, which not only has low safety performance during construction but is also cumbersome and wastes working time. In addition, most of the trough box covers are also welded during installation, making it inconvenient to disassemble later. Moreover, when arranging cables in current cable trough boxes, the cables are directly placed inside the trough boxes, which may cause the internal cables to become entangled, making subsequent maintenance inconvenient.

[0004] Therefore, a new type of substation cable trough box is proposed. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In order to overcome the shortcomings of the existing technology, a new type of substation cable trough box is proposed to solve the problems that the cable trough boxes are welded, resulting in slow connection efficiency between trough boxes, the box cover is welded, resulting in inconvenience in disassembly, and the internal cables are unevenly arranged, resulting in cable entanglement.

[0010] The box cover is provided with an elastic plate on the outer protruding part of the box cover, and a side clamping plate is vertically provided at the lower end of the elastic plate to fit and contact with the side of the slot box.

[0011] Furthermore, the insertion fixing block and the insertion fixing groove are arranged in a U shape, and the through positioning hole and the fixing threaded hole are located on the same central axis.

[0012] Furthermore, a fixing groove is provided at the upper end of the side of the groove box, and a fixing block is provided at the inner bottom end of the side clamping plate and connected to the fixing groove.

[0013] Furthermore, the fixing groove, the side clamping plate and the fixing block can be arranged at intervals.

[0014] Furthermore, a bottom placement plate is provided at intervals on the bottom end surface of the trough box, symmetrical positioning screws are installed on both sides of the bottom placement plate, a plurality of movable placement plates are provided on the upper end of the bottom placement plate, and middle positioning holes are provided on both sides of the movable placement plate to connect with the positioning screws, and a manual knob is connected to the top of the positioning screw.

[0015] Furthermore, the upper end surface of the bottom placement plate and the upper and lower end surfaces of the movable placement plate are both provided with corresponding arc-shaped placement grooves.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model has the following beneficial effects:
