[0002] With the rapid development of the power industry, high-voltage metering cabinets are widely used in substations, industrial and mining enterprises, and other places as an indispensable and important equipment in the power system. However, due to the possibility of electrical failures, short circuits or overloads inside the equipment, explosion accidents sometimes occur when the high-voltage metering cabinets are in use. Such explosion accidents are often sudden and destructive. Once they occur, the huge energy generated by the explosion will not only damage the equipment itself, but also cause serious damage to the equipment itself.

[0003] Then the doors of most existing box-type transformer high-voltage metering cabinets are usually locked by simple buckles or door locks. They may be ejected under the impact of the explosion, forming high-speed flying objects, which directly threaten the lives and safety of on-site staff and surrounding personnel. Therefore, we need to design an explosion-proof box-type transformer high-voltage metering cabinet that can ensure that the cabinet door will not fly out due to the impact force and cause personal injury during an explosion.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] See also Figure 1-5 The utility model provides a technical solution: an explosion-proof box-type high-voltage metering cabinet, comprising a box body 1, a first rotating shaft 3 is arranged on one side of the box body 1, the first rotating shaft 3 is connected to a cabinet door 2, a third installation groove 22 is opened on the inner side of the box body 1, a baffle 23 is arranged in the third installation groove 22, a plurality of slide grooves 16 are opened on both sides of the third installation groove 22, a plurality of second sliders 17 are arranged on both sides of the baffle 23, the second sliders 17 are limited by the slide grooves 16, and a buffer component is designed on the side of the baffle 23.

[0019] In this embodiment, a third mounting groove 22 is opened through the inner side of the box body 1, a baffle 23 is arranged in the third mounting groove 22, a plurality of slide grooves 16 are opened on both sides of the third mounting groove 22, a plurality of second sliders 17 are arranged on both sides of the baffle 23, the second sliders 17 are limited by the slide grooves 16, and a buffer component is designed on the side of the baffle 23, so that when an explosion occurs in the high-voltage metering cabinet, the internal shock wave will immediately touch the baffle 23, causing the buffer component to operate and triggering the locking structure at the same time, so that the cabinet door 2 is locked to prevent the cabinet door 2 from flying out due to the impact force and causing damage.

[0020] Specifically, the buffer assembly includes a first slide bar 5, a first installation groove 4 is opened on the inner side of the third installation groove 22, the first slide bar 5 is installed inside the first installation groove 4, a first slider 6 is slidably arranged on the periphery of the first slide bar 5, first springs 7 are arranged on both sides of the first slide bar 5, a protective sleeve 8 is arranged on the periphery of the first spring 7, the protective sleeve 8 is fixedly connected to the first slider 6, and a locking structure is arranged on the end of the first slide bar 5 close to the cabinet door 2; a second installation groove 11 is opened on one side of the baffle 23, a second slide bar 12 is installed inside the second installation groove 11, second springs 13 are arranged on the periphery of both ends of the second slide bar 12, the second spring 13 is fixedly installed at both ends inside the second installation groove 11, a connecting block is arranged on one end of the second spring 13, a second rotating shaft 14 is rotatably arranged on the side of the first slider 6, the second rotating shaft 14 is connected to the telescopic rod 15, and the telescopic rod 15 is connected to the connecting block through the second rotating shaft 14.

[0021] In this embodiment, a third mounting groove 22 is provided on the inner side of the box body 1 of the box-type transformer high-voltage metering cabinet, and a slidable baffle 23 is installed in the groove. The two sides of the baffle 23 cooperate with the slide groove 16 through multiple second sliders 17 to ensure the stability and smoothness of the baffle 23 during the sliding process. In order to enhance the buffering effect of the baffle 23, a buffer assembly is introduced on the side of the baffle 23. When the first slider 6 moves along the first slide rod 5 when subjected to external force, the impact force is buffered by the compression of the first spring 7, thereby reducing the damage of the impact force to the box body 1 and the internal equipment. The provision of the protective sleeve 8 not only enhances the protective effect of the first spring 7, but also ensures the stability of the first slider 6 during the sliding process. The locking structure designed at one end of the first slide rod 5 enables the cabinet door 2 to be locked tightly in the event of an explosion to prevent dangerous accidents. This not only improves the explosion-proof performance of the box body 1, but also enhances its structural stability and durability, making the box-type transformer high-voltage metering cabinet safer and more reliable in practical applications.

[0022] Specifically, the locking structure includes a connecting sleeve 10, a fourth mounting groove 9 is opened at one end of the first sliding rod 5 close to the cabinet door 2, the connecting sleeve 10 is arranged in the fourth mounting groove 9, a section of the fourth mounting groove 9 is opened with a groove 18, a limiting sleeve 19 is arranged in the groove 18, the limiting sleeve 19 is connected to the connecting sleeve 10, and an even limiting groove 20 is opened on the inner side of the cabinet door 2, and a limiting ring 21 is installed in the limiting groove 20.

[0023] In this embodiment, a fourth mounting groove 9 is opened at one end of the first sliding rod 5 close to the cabinet door 2, and a connecting sleeve 10 is arranged in the fourth mounting groove 9. A groove 18 is opened at a section of the fourth mounting groove 9, and a limiting sleeve 19 is arranged in the groove 18. The limiting sleeve 19 is connected to the connecting sleeve 10. An even limiting groove 20 is opened on the inner side of the cabinet door 2, and a limiting ring 21 is installed in the limiting groove 20. Through a simple structure, when the buffer assembly is triggered, the cabinet door 2 can be locked in time to prevent the occurrence of dangerous accidents.

[0024] Specifically, the diameter of the limiting groove 20 is the same as the diameter of the slot 18 .

[0025] In this embodiment, the diameter of the limiting groove 20 is the same as the diameter of the slot 18 , so that the limiting sleeve 19 can smoothly enter the limiting groove 20 and fit closely therewith, thereby achieving stable locking of the cabinet door 2 .

[0026] Specifically, the buffer assembly and the locking structure are evenly arranged in an array inside the third installation groove 22 .

[0027] In this embodiment, the buffer components and locking structures are evenly arrayed inside the third installation groove 22, so that the impact force resistance inside the box-type high-voltage metering cabinet is improved, which not only optimizes the force distribution, but also allows the impact force to be dispersed and absorbed more evenly and effectively.

[0028] The working principle and use process of the utility model are as follows: when using an explosion-proof box-type high-voltage metering cabinet, when encountering an explosion, the buffer component inside the cabinet will be activated immediately, and the impact force can be effectively absorbed and dispersed through the coordinated action of multiple first slide bars 5 and first springs 7 evenly arrayed in the third mounting groove 22. At the same time, the locking structure ensures that the cabinet door 2 is tightly closed, and works together with the buffer component to limit the energy and fragments generated by the explosion within the cabinet. This design enables the cabinet to maintain structural integrity when facing an explosion, and effectively prevents damage to the external environment and personnel caused by the explosion.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
