DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following preferred embodiments are referred to and are given, and the utility model is further explained in detail. However, it should be indicated that, many details listed in the specification are only for making the reader have a thorough understanding of one or more aspects of the utility model, and even if these specific details are not implemented, these aspects of the utility model can also be realized.

[0023] Please refer to Figures 1 to 6 , the utility model provides a kind of low-voltage reactive power compensation cabinet, technical scheme is as follows:

[0024] Including cabinet body 1, the cavity 2 is provided in the cabinet body 1, the cabinet body 1 is equipped with multiple control modules 3, the cabinet body 1 front end is equipped with cabinet door, and cabinet door includes main cabinet door 4 and small cabinet door 5, the main cabinet door 4 is equipped with lock hole 6, and the main cabinet door 4 is equipped with lock core 7 inside, the small cabinet door 5 is equipped with lock catch 8, and lock core 7 is matched with lock catch 8, the cabinet body 1 is equipped with auxiliary assembly for the cabinet door convenient opening and closing.

[0025] In actual application, compensation cabinet is often placed in machine room, substation and other narrow space, when the side of compensation cabinet is adjacent to other equipment, maintenance personnel will encounter space limitation when needing to open cabinet door, leading to cabinet door cannot be completely opened;This situation increases the maintenance difficulty of maintenance personnel, cannot fully expose equipment in cabinet, and further limit operation space;

[0026] By setting cabinet door as main cabinet door 4 and small cabinet door 5, small cabinet door 5 can quickly access key components inside compensation cabinet, such as capacitor, contactor, etc., avoid opening entire main cabinet door 4, for some daily inspection or small range maintenance task, maintenance personnel only need to open small cabinet door 5 to enter working area, reduce unnecessary operation steps, improve work efficiency;

[0027] When a large-scale maintenance work needs to be carried out, the main cabinet door 4 can be conveniently opened through the auxiliary assembly, avoiding the situation that the cabinet door cannot be completely opened due to space limitation, which limits the operation field of view of the maintenance personnel and increases the risk of misoperation.

[0028] The auxiliary assembly comprises a placing box 9 arranged on the outer side wall of the cabinet body 1, a placing cavity 10 is formed in the placing box 9, and the main cabinet door 4 can move in and out of the placing cavity 10, two slide rails 11 are symmetrically arranged in the placing cavity 10, slide grooves 12 matched with the slide rails 11 are formed in the upper and lower ends of the main cabinet door 4, and the main cabinet door 4 is designed in a segmented manner and connected through a connecting assembly.

[0029] The main cabinet door 4 designed in a sliding switch mode can be operated in a narrow environment through the cooperation of the slide rails 11 and the slide grooves 12, without the need of a large space for outward opening; this design is particularly suitable for occasions where the space for placing the compensation cabinet is limited, without the need of reserving a large side space, and the main cabinet door 4 can be opened or closed by sliding along the slide rails 11, thereby maximizing the use of the limited installation space.

[0030] The main cabinet door 4 of the traditional compensation cabinet often needs a large outward opening angle to be completely opened, while the sliding main cabinet door 4 only needs to be slid along the slide rails 11, thereby reducing the space requirements in front and back or left and right, especially in the case that other equipment is placed on one side of the cabinet body 1, the design of the sliding switch significantly reduces the influence of space limitation on the maintenance work.

[0031] The main cabinet door 4 is divided into a front door 401 and a rear door 402, the lock hole 6 is arranged on the front door 401, and the connecting assembly comprises two recesses 13 symmetrically formed on the side wall of the front door 401, two slide blocks 14 are arranged in each recess 13, the two slide blocks 14 are respectively located on the upper and lower sides of the recess 13, a rotating rod 15 is arranged between the two slide blocks 14, a connecting plate 16 is arranged on each rotating rod 15, and the other end of each connecting plate 16 is hingedly connected with the rear door 402.

[0032] The slide blocks 14 arranged in the recesses 13 can ensure that the front door 401 moves stably when being opened and closed. Through the close cooperation of the slide blocks 14 and the recesses 13, the front door 401 will not shake or jam; especially in the case of space limitation or frequent operation, this design can effectively reduce accidental damage caused by shaking of the cabinet door and ensure smoother use.

[0033] The design of the sliding block 14 and the groove 13 provides more opening angle options for the front door 401, and through the sliding of the sliding block 14, the front door 401 can be flexibly adjusted to meet the needs of different maintenance tasks; for example, in some cases where the door body needs to be partially opened, the maintenance personnel can control the opening range of the front door 401 without having to open the door body completely, and at the same time, the rotating radius of the entire main cabinet door 4 is reduced, further improving the convenience of opening and closing the main cabinet door 4.

[0034] The cross-sectional shape of the sliding rail 11 is in the shape of a sandglass; due to the narrow middle and wide ends of the sandglass-shaped sliding rail 11, this shape can better lock the sliding groove 12 at the upper and lower ends of the cabinet door, avoiding the sliding groove 12 from disengaging from the track, thereby improving safety and stability; the sandglass-shaped structure provides a natural guide to keep the pulley in the center of the track, reducing left and right swinging during sliding. This can ensure smoother and more stable opening and closing of the cabinet door, reducing the phenomenon of jamming; and the sandglass structure can evenly distribute the weight of the cabinet door, reducing the excessive pressure on one side of the sliding rail 11, thereby prolonging the service life of the sliding rail 11 and the cabinet door.

[0035] The lock hole 6 is hexagonal, and the lock hole 6 is provided with an opening 17, and the lock hole 6 is provided with a protruding portion 18; the hexagonal lock hole 6 plus the opening 17 design limits the insertion method of the lock, and only a specific shape key or tool can be used to correctly unlock, the internal protruding portion 18 tightly fits with a specific part of the key or tool, further limiting the insertion direction and rotation angle, preventing non-workers from trying to open with mismatched keys or tools; the protruding portion 18 in the lock hole 6 is equivalent to an additional mechanical protection, only a key with a specific groove 13 or shape can match it, even if trying to break forcibly or using a universal key, the lock will not be able to rotate due to the mismatched shape, enhancing the anti-theft and anti-misoperation mechanism of the compensation cabinet.

[0036] The above only describes preferred embodiments of the present application, and it should be noted that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
