Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, and particularly relates to a switch cabinet with safety protection. Background Technique

[0002] The main function of the switch cabinet is to open, close, control and protect electrical equipment during the processes of power generation, power transmission, power distribution and power conversion in the power system. It is mainly applicable to various different occasions such as power plants, substations, petrochemical industries, metallurgical rolling mills, light industry and textile industries, factories and mines, residential quarters, high-rise buildings, etc.

[0003] Most of the existing switch cabinet doors are connected by screws or rivets, and only have basic dust-proof functions, but do not have the functions of flame retardancy and arc prevention. This greatly reduces the protection level of the cabinet body, and it is also easy to cause arc during the operation of the components in the cabinet or the arc overflow when a fault occurs, resulting in equipment accidents or personal injuries. At the same time, there are no protective components on both sides of the open door of the switch cabinet. Once the side of the switch cabinet is collided, it is easy to cause the deformation of the switch cabinet door. Even when the switch cabinet collides, it will cause certain damage to the internal parts of the switch cabinet, resulting in the switch cabinet being unable to be used normally.

[0004] In view of the above problems, a switch cabinet with safety protection is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a switch cabinet with safety protection, which solves the problems in the background technique that the arc overflow of the existing switch cabinet door is easy to cause equipment accidents or personal injuries, and at the same time, there are no protective components on both sides of the open door of the switch cabinet, and the collision during opening the door may cause certain damage to the internal parts of the switch cabinet.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0025] Combined Figure 1 , a switch cabinet with safety protection of the present utility model includes a switch cabinet body 1, a high-voltage component 2 is fixedly arranged inside the switch cabinet body 1, a protective cabinet door 3 is rotatably arranged on one side of the switch cabinet body 1, an earthing switch 4 is fixedly arranged at the lower end of the switch cabinet body 1. The switch cabinet body 1 includes a grounding bottom sealing plate 11, and the earthing switch 4 includes a flexible connecting piece 43 connected to the lower end of the switch cabinet body 1, a post insulator 42 connected to one side of the flexible connecting piece 43, a base frame 41 connected to one side of the post insulator 42, and a contact blade 44 for controlling the opening and closing of the base frame 41. The protective cabinet door 3 includes two groups of insertion posts 31 fixedly arranged at the upper end of the grounding bottom sealing plate 11, a cabinet door part 32 inserted through the insertion posts 31, and a rotary lock 34 rotatably engaged inside the grounding bottom sealing plate 11.

[0026] Specifically, the grounding bottom cover plate 11 surrounds and fixes the grounding switch 4. The flexible connecting piece 43 realizes the grounding of the high-voltage component 2. The base frame 41 is a support structure for the grounding switch 4, used to fix and support other components. The post insulator 42 prevents the grounding switch 4 from short-circuiting with other devices during operation. The contact blade 44 realizes the switching operation of grounding. The grounding switch 4, in combination with the grounding bottom cover plate 11, supports an isolation area. When a fault occurs, it can effectively prevent the generation and spread of electric arcs, ensuring the safe operation of the switch cabinet. The insertion post 31 penetrates and inserts into the cabinet door piece 32. The cabinet door piece 32 can be rotated open and pushed inward along the cabinet body. The rotary lock 34 can be rotated, enabling the cabinet door piece 32 to be opened or closed. The rotational storage of the cabinet door piece 32 provides additional protection for the equipment, preventing damage to the internal parts of the switch cabinet caused by collisions when the door is opened.

[0027] The following further describes the present utility model in conjunction with embodiments.

[0028] Embodiment 1:

[0029] Combined with Figures 2 - 4 , the switch cabinet body 1 includes a heightening post 12 provided at the lower end of the grounding bottom cover plate 11. An upper cover plate 13 is fixedly arranged inside the grounding bottom cover plate 11. The heightening post 12 increases the height to prevent the switch cabinet from being affected by moisture. The grounding bottom cover plate 11 provides support for the protective cabinet door 3, and the upper cover plate 13 realizes the internal enclosure of the switch cabinet.

[0030] The high-voltage component 2 includes a load joint 21 provided inside the upper cover plate 13. One end of the load joint 21 is connected with a connecting plate 22. One side of the connecting plate 22 is connected with a composite insulator 23. The load joint 21 is connected to the load. The connecting plate 22 is used to connect various components in the power system. The composite insulator 23 is an insulating device to prevent short circuits.

[0031] The high-voltage component 2 further includes a protector 24, which is connected to the grounding switch 4. The protector 24 monitors the voltage in real time. When the voltage exceeds or is lower than the set value, the protector 24 will send a signal to cause the grounding switch 4 to cut off the power supply, preventing the equipment from operating under abnormal voltage and ensuring the safety of the equipment.

[0032] Embodiment 2:

[0033] Combined with Figures 3 - 5 , the protective cabinet door 3 further includes a retaining piece 33 fixedly arranged at the center of the upper end of the heightening post 12. The retaining piece 33 realizes the blocking of one side of the cabinet door piece 32, ensuring that the two cabinet door pieces 32 are collinear when closed.

[0034] A slot 321 is formed inside the cabinet door piece 32. The insertion post 31 slides through the slot 321. After the cabinet door piece 32 is rotated open, the cabinet door piece 32 can be pushed to slide inward along the insertion post 31 to realize the storage protection of the cabinet door piece 32.

[0035] One side of the rotary lock 34 is provided with a large round block 341, and the other side is a small round block 342. When the rotary lock 34 rotates until the large round block 341 is on top, the two closed cabinet door members 32 can be locked. When the rotary lock 34 rotates until the small round block 342 is on top, the cabinet door members 32 can be opened.

[0036] The earthing switch 4 further includes a flexible connecting member 43 connected to one side of the protector 24. The flexible connecting member 43 is connected to the post insulator 42, and the flexible connecting member 43 is grounded to prevent damage to the earthing switch 4 caused by equipment vibration or displacement, and ensure that the high-voltage component 2 can be continuously grounded to spread the electric arc to the ground.
