Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage distribution cabinets, in particular to a high and low voltage distribution cabinet which is easy to maintain. Background Art

[0002] As the name implies, high and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. The low voltage distribution cabinets are then connected to distribution boards, control boxes and switch boxes of various power users. When used outdoors, they can protect internal switches, circuit breakers, fuses, buttons, indicator lights, instruments and wires.

[0003] After searching, the existing Chinese patent with publication number CN202320885029.7 discloses a high and low voltage distribution cabinet which is easy to maintain. In windy weather, the cabinet door can be quickly limited by L-shaped blocks, plug rods and limit plug blocks. By pulling out two plug strips, it can play a role in wind blocking. The plug strips can be used to limit the wind shield. The limit sleeve can prevent the plug rod from slipping on the L-shaped block. The spring makes the limit block more stable when inserted into the limit hole. The bolts and mounting plates are used to facilitate disassembly and assembly of the L-shaped block. When there is no wind, the cabinet door in the limited position will not affect the operating space of the maintenance personnel. The wind shield can be pushed back into the high and low voltage distribution cabinet without occupying the operating space.

[0004] The above technical scheme has the following defects: although such high and low voltage distribution cabinets can block the wind at the cabinet door position by inserting strips to prevent strong winds from affecting the operation of maintenance personnel, it may not be safe enough when emergency repairs are carried out in rainy and snowy weather. In order to facilitate maintenance in rainy and snowy weather, a high and low voltage distribution cabinet that is easy to maintain is proposed. The cabinet is provided with a retractable maintenance cabin, which can be retracted in the distribution cabinet during daily use. When the high and low voltage distribution cabinets are maintained in strong winds, the maintenance cabin can be electrically discharged, and the staff can carry out maintenance work in the maintenance cabin, thereby preventing the outer wall from being affected by rain, snow and strong winds.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
