Description

Technical Field

[0001] This utility model relates to the field of ring main unit protection technology, and in particular to a ring main unit protection device. Background Technology

[0002] A ring main unit is an electrical device consisting of a set of high-voltage switchgear installed in a metal or non-metal insulated cabinet or assembled into a modular ring main unit. Ring main units are usually installed outdoors, where the complex environment can easily damage the equipment. Therefore, ring main units should have a certain level of physical protection.

[0003] Existing ring main unit protection devices use a single-door panel design, which exposes the entire ring main unit to the outside world after the door is opened, increasing the risk of use and causing certain adverse effects on users. In order to address the shortcomings of existing technologies, we propose a ring main unit protection device. Utility Model Content

[0004] The main purpose of this utility model is to provide a ring main unit protection device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective device for a ring main unit includes a main body. A door panel is symmetrically and rotatably connected to the inner wall of the main body. A rubber strip is threaded through one side of the bottom of the inner wall of the main body. A first limiting groove is formed at the bottom of the inner wall of the main body. An insulating baffle is inserted into the first limiting groove. Four sets of observation ports are evenly formed on one side of the insulating baffle. An insulating cover plate is rotatably connected to the inner wall of each observation port. A rubber pad is detachably installed on one side of the insulating cover plate. Limiting plates are symmetrically and fixedly connected to the inner wall of each observation port. Through holes are symmetrically formed on one side of the insulating baffle. A fixing plate is fixedly connected to one side of the inner wall of each through hole. An elastic silicone column is fixedly connected to one side of the fixing plate. A movable pin is fixedly connected to one end of each elastic silicone column.

[0007] Preferably, one side of the door panel abuts against one side of the insulating baffle, and one side of the door panel abuts against one side of the insulating cover plate.

[0008] Preferably, one side of the rubber strip abuts against one side of the insulating baffle, and the top of the rubber strip abuts against one side of the bottom of the door panel.

[0009] Preferably, one side of the rubber pad abuts against one side of the limiting plate, one side of the limiting plate is vertically flush with one side of the insulating baffle, and a semi-circular groove is provided on one side of the observation port of the insulating baffle.

[0010] Preferably, a second limiting groove is provided on one side of the top of the inner wall of the protective device body. The second limiting groove provided in the protective device body is symmetrical to the first limiting groove, and the inside of the second limiting groove provided in the protective device body is inserted into the top of the insulating baffle.

[0011] Preferably, the movable pin is slidably connected to the through hole of the insulating baffle, and one end of the movable pin abuts against the bottom of the inner wall of the main body of the protective device.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the insulating baffle and insulating cover serve as the second layer of protection behind the door panel. Opening the insulating cover at the corresponding position on the insulating baffle allows operation of the ring main unit behind it, reducing the contact area between the ring main unit and the outside world during a single operation. With the insulating baffle and insulating cover as a second layer of protection, the ring main unit is safer to use.

[0014] 2. In this utility model, the movable pin is inserted into the through hole of the insulating baffle. The insulating baffle is pulled out from the second limiting groove of the main body of the protective device and then tilted out after entering the first limiting groove. The insulating baffle has a simple disassembly and assembly structure, which is convenient for operators. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-3As shown, a ring main unit protection device is provided. The ring main unit is housed by a main body 1. The main body 1 and the door panel 2 form the external protection of the ring main unit. When it is necessary to operate the ring main unit inside the main body 1, the door panel 2 is opened on the main body 1, exposing the insulating baffle 4 and insulating cover 5 behind the door panel 2. At this time, the insulating baffle 4 and insulating cover 5 work together with the main body 1 as the external protection of the ring main unit. Thus, the insulating baffle 4 and insulating cover 5 serve as the second layer of protection behind the door panel 2 on the main body 1. Then, the insulating cover 5 at the corresponding position on the insulating baffle 4 is opened according to the required operation position. The insulating cover 5 is pulled up through the semi-circular groove on one side of the observation port of the insulating baffle 4 and opened in the observation port of the insulating baffle 4, thereby operating on the surface of the ring main unit behind the insulating cover 5, reducing the exposed area of ​​the ring main unit when operating it, and isolating the ring main unit from the outside as much as possible.

[0022] After the operation is completed, the insulating cover plate 5 is placed on the insulating baffle 4. The insulating cover plate 5 closes again on the insulating baffle 4. Then the door plate 2 is closed. After the door plate 2 is closed on the main body 1 of the protective device, one side of the door plate 2 abuts against the insulating baffle 4 and the insulating cover plate 5. The insulating cover plate 5 pushes the rubber pad 6 to fit tightly against the side of the limiting plate 7. Thus, the door plate 2 is used to limit and fix the position of the insulating cover plate 5 inside the insulating baffle 4. The connection between the insulating baffle 4 and the insulating cover plate 5 is tighter, and the overall protection is better.

[0023] Example 2, as Figure 2 and Figure 4 As shown, a ring main unit protection device, when installing the ring main unit inside the main body 1 of the protection device or when the entire ring main unit needs to be opened for operation and maintenance, opens the door panel 2 and then opens the two insulating covers 5 on the bottom side of the insulating baffle 4. Then, it is inserted into the main body 1 of the protection device through the observation port opened in the insulating baffle 4. The movable pin 10 is pushed from the inside of the insulating baffle 4. The movable pin 10 compresses the elastic silicone column 9 in the through hole opened in the insulating baffle 4 with the fixed plate 8 as the base. The movable pin 10 retracts into the through hole opened in the insulating baffle 4, so that the movable pin 10 no longer restricts the insulating baffle 4, and pulls the insulating baffle. 4. The insulating baffle 4 moves downward, and the top of the insulating baffle 4 exits from the second limiting groove opened in the main body 1 of the protective device. The bottom of the insulating baffle 4 extends into the first limiting groove opened in the main body 1 of the protective device. Then, the insulating baffle 4 is tilted on the main body 1 to compress the rubber strip 3, so that the top of the insulating baffle 4 protrudes from the main body 1 of the protective device. Then, the insulating baffle 4 is pulled out from the first limiting groove opened in the main body 1 of the protective device, and the insulating baffle 4 is removed from the main body 1 of the protective device, which facilitates the subsequent installation of the ring main unit or the overall operation and maintenance inside the main body 1 of the protective device.

[0024] It should be noted that this utility model is a ring main unit protection device. In use, the insulating baffle 4 and the insulating cover 5 serve as the second layer of protection behind the door panel 2. When it is necessary to open the door panel 2 to operate the ring main unit inside the main body 1 of the protection device, the insulating cover 5 at the corresponding position on the insulating baffle 4 can be opened to operate the ring main unit behind it, reducing the contact area between the ring main unit and the outside world during a single operation. With the insulating baffle 4 and the insulating cover 5 as the second layer of protection, the use of the ring main unit is safer. Furthermore, by pushing the movable pin 10 into the through hole opened in the insulating baffle 4, the movable pin 10 no longer limits the insulating baffle 4. Then, the insulating baffle 4 is pulled out from the second limiting groove opened in the main body 1 of the protection device and inserted into the first limiting groove. The insulating baffle 4 is tilted and pulled out of the compression rubber strip 3 inside the main body 1 of the protection device. The insulating baffle 4 has a simple disassembly and assembly structure, which is convenient for operators.
