Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, and more particularly to a high-voltage switch cabinet for mining that is easy to maintain and suitable for upgrading, reconstruction and subsequent maintenance. Background Art

[0002] In the mining industry, the importance of power equipment cannot be ignored. The mining industry requires a large amount of electricity to drive equipment, and high and low voltage distribution cabinets, as key components of power transmission and distribution, play a very important role. Mining high-voltage switchgear has strong sealing, dust and explosion resistance and other features.

[0003] When a switch cabinet is first installed, it is often customized as a whole cabinet, with the cabinet and components customized according to functional requirements. However, after a period of use, routine maintenance or component replacement often encounters the following problems: 1. The existing cabinet can generally only be inspected through the front or back door openings. However, the space inside the cabinet is limited, and there are blind spots in the inspection of some components inside the cabinet, and tools are difficult to use, which makes maintenance operations inconvenient. 2. When the position of the circuit or components is adjusted, the space inside the original customized cabinet that was originally installed is limited and generally cannot meet the needs of partial disassembly and replacement. It is often necessary to rewire and adjust the position of the corresponding components. If it is difficult to disassemble the components, they need to be completely disassembled or destructively disassembled and then reassembled. The difficulty and cost of subsequent upgrades and maintenance are greatly increased. 3. Components located on the sides of the cabinet are currently the most difficult to maintain and inspect. Switch cabinets generally have door openings and opening and closing panels on both sides, but components on the sides and corners are generally difficult to inspect and maintain after installation. In particular, when components in these locations are damaged and replaced, the surrounding components must also be removed. This is especially true for large switch cabinets with multiple cabinets interconnected, where there are no reserved inspection and observation ports between the cabinets. Replacing components between multiple cabinets is even more complicated and difficult. In some special cases, the cabinets may even need to be destroyed before replacement. Utility Model Content

Therefore, by opening multiple window holes on both sides of the main cabinet 1, the equipment can be moved in more visual and operating directions during maintenance, making the maintenance process more convenient. After the outer cover 4 is inserted into the outer frame 2, the window hole can be closed. The sealing performance of the window hole can be ensured by the inner cover assembly 7 being close to the inner fixed frame 3, thereby ensuring the mining performance of the device. The two locking frames 5 can be controlled to shift outward through the driving mechanism 6, so that the two locking frames 5 are inserted into the pin holes on the front and back of the outer frame 2, so that the outer cover 4 can be locked inside the outer frame 2 to prevent it from falling off. In addition, the cabinet of this application differs from other mining cabinets in that multiple sets of cabinets can be interconnected and spliced ​​to form an integrated cabinet, and multiple cabinets can be connected through window holes. The window holes that need to be blocked are inserted into the outer frame 2 through the outer cover 4. This does not damage the cabinet structure and can achieve independent sealing of the window holes, greatly improving the flexibility of subsequent upgrades and modifications. Compared with low-voltage switchgear, the high-voltage switchgear mentioned in this application has a higher voltage level and load. This application can effectively meet higher electricity safety standards.
