Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to an electric power construction ring network cabinet which is easy to maintain. Background Art

[0002] Ring main unit is a high-voltage switch cabinet, which is mainly used in electrical transmission and distribution equipment. It is generally installed in a metal or non-metallic insulating cabinet, and can also be made into an assembled interval ring main unit. The core part of the ring main unit adopts load switches and fuses, which has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. The lighting equipment inside the existing ring main unit is usually fixed and designed to be built-in or integrated in the cabinet to provide necessary lighting, which is convenient for operators to perform maintenance and inspection work in dim or night conditions. These lighting equipment can be LED lights or other types of lighting. They are usually powered by the power supply system of the cabinet to ensure stable lighting when needed. However, the use of fixed lighting equipment requires the addition of LED lighting in various areas of the cabinet. More lighting equipment will increase the manufacturing and production costs of the ring main unit, resulting in a certain waste of resources. Utility Model Content

[0014] As a further improvement of the above technical solution: the trapezoidal lead screw and the guide rail are arranged parallel to each other.

[0015] The beneficial effect of this improvement is that the mutually parallel arrangement enables the trapezoidal lead screw to drive the lead screw slider to push the storage tray out, thereby ensuring the stability and reliability of the storage tray when sliding.

[0016] To facilitate sliding of the mounting base:

[0017] As a further improvement of the above technical solution: a sliding groove is provided in the position of the square groove close to the mounting seat.

[0018] The beneficial effect of this improvement is that during the lighting process, the position of the LED lamp can be adjusted by pulling the mounting seat to slide along the square groove and the slide groove opened on the square groove, so that the device can fully illuminate the interior of the ring network cabinet, and the sliding groove can guide and limit the sliding of the mounting seat.

[0019] To facilitate the installation of the LED lamp on the mounting base:

[0020] As a further improvement of the above technical solution: a limiting plug rod is circumferentially welded on the outer side of the LED lamp, and a battery is arranged at the bottom of the LED lamp.

[0021] As a further improvement of the above technical solution: an L-shaped sliding groove is provided on the inner circumference of the mounting seat.

[0022] The beneficial effect of this improvement is that the limiting plug rod welded on the outer side of the LED lamp can be inserted into the L-shaped sliding groove opened on the inner side of the mounting seat and then rotated, so that the LED lamp can be firmly and quickly installed in the mounting seat.

[0023] To facilitate the partitioning of the device:

[0024] As a further improvement of the above technical solution: the storage trays are distributed at equal intervals on the inner side of the ring network cabinet.

[0025] The beneficial effect of this improvement is that the interior of the device can be partitioned by using storage trays distributed at equal intervals. BRIEF DESCRIPTION OF THE DRAWINGS
