[0002] Mine high-voltage protection switchgear is a common distribution protection switchgear for open-pit mines, underground mines (non-coal mines), large-scale water conservancy and power projects. It is suitable for supporting equipment with three-phase AC 50Hz and 10kV or less. It is used as a distribution protection switchgear for the front and branch trunk lines of mining equipment such as electric excavators and rotary drills to control the start and stop of high-voltage (6-10kV) asynchronous motors and variable frequency motors, and supply power to the main power transformer. With the progress of society and the need for green mine construction, the requirements for power system equipment are getting higher and higher, especially the requirements for the safety, stability, networking, maintainability and intelligence of mining equipment operation are increasing. The operating environment of traditional outdoor high-voltage switchgear for mines is harsh. Due to factors such as overheating and reduced insulation performance, the probability of failure increases during long-term uninterrupted operation of the switchgear, and the safety hazard is large. Once a failure occurs, it will cause significant losses to the enterprise.

[0003] There are many problems or inconveniences in the after-sales maintenance of traditional mining equipment, such as the inability to collect equipment operation data and the inability to know the equipment operation status, resulting in untimely equipment maintenance and failures that should not have occurred; once the equipment operation failure alarm is shut down, even if the manufacturer immediately arranges after-sales engineers to go to the production site, the mine production site is far away and the time spent will affect the timely recovery of the equipment; secondly, the on-site maintenance personnel have different levels of understanding of the equipment, and the effect of remote telephone communication is often not ideal, resulting in the manufacturer's engineers' inaccurate judgment of the cause of the equipment failure and the damaged parts. When the after-sales engineer arrives at the site to check, it may be necessary to take the parts, resulting in extended equipment downtime. Existing switch cabinets require a lot of labor to move or use forklifts to move. In the harsh mining environment, the transportation cost is high and the difficulty is great.

[0046] Further, refer to Figure 6 , further comprising a lifting mechanism 40 disposed between the chassis frame and the high-voltage protection switch cabinet 10, the lifting mechanism 40 being used for facilitating disassembly, assembly and maintenance of the high-voltage protection switch cabinet;

[0047] The lifting mechanism 40 comprises:

[0048] A support plate 42 is provided on the chassis frame; one end of the support plate 42 is hinged to the chassis frame;

[0049] A lifting cylinder 41, wherein the cylinder seat of the lifting cylinder 41 is fixedly connected to the chassis frame, and the output end of the lifting cylinder 41 is fixedly connected to the support plate 42;

[0050] The extension end 43 is disposed at one end of the support plate 42 away from the lifting cylinder 41; the extension end 43 can be automatically retracted from one end of the support plate 42;

[0051] A limit block 44 is movably disposed at the end of the extension end 43 , and the limit block 44 is used for limiting the position of the high-voltage protection switch cabinet.

[0052] In this embodiment, the support plate 42 is provided with an internal cavity, a track is provided inside the cavity of the support plate 42, an electric slider adapted to the track is provided on the extension end 43, and the extension end 43 can be automatically extended and retracted from the support plate.

In the case that the first door 11 and the second door 12 are damaged, the door buckles can temporarily replace the door locks to avoid the door being unable to be closed due to damage to the door body.

[0056] Furthermore, the touch display screen, CPU, electrical parameter detection unit, wireless transceiver module, locking switch control and sound and light alarm control are arranged in the second door 12. In this embodiment, the second door 12 is a low-voltage room door.

[0057] Furthermore, the rear side of the cabinet is provided with a cable connection barrel 18. In this embodiment, the number of the cable connection barrels 18 is 2 or 3, and one of the cable connection barrels 18 is used for incoming wires, another for outgoing wires, and one for outgoing wires is reserved.

[0058] Further, it also includes a signal light 14 arranged on the top of the cabinet. In this embodiment, the signal lights 14 are yellow and red. The yellow light indicates that the switch cabinet is energized, and the red light is a switch trip indicator light, and the red light indicates a switch trip warning.

[0059] Furthermore, it also includes a hook 13 arranged on the top of the cabinet and a forklift hole 27 arranged on the chassis frame, which is convenient for dragging in the mining area.
