Description

Technical Field

[0001] The utility model relates to an insulation protection device for a comprehensive distribution box, in particular to an insulation protection device for a comprehensive distribution box, belonging to the technical field of comprehensive distribution boxes. Background Technique

[0002] A comprehensive distribution box is a new type of comprehensive control box integrating power distribution, metering, protection, control, and reactive power compensation, which is widely used in substations, factories, industrial and mining enterprises, large power plants, petroleum, chemical enterprises, large steel plants, power centers of high-rise buildings, reactive power compensation, metering, power distribution, etc. To prevent electric shock to workers when electrical equipment in the distribution box leaks electricity, an insulation protection board is used to isolate the electrical equipment from the distribution box housing.

[0003] An insulation protection device for a distribution box disclosed in the Chinese Patent Application Publication Specification CN213151384U insulates and blocks the mounting plate from the distribution box body through an insulation board, insulates and blocks the bolt from the first through hole of the distribution box body through an insulation cylinder, and insulates and blocks the nut from the outer wall of the distribution box through an insulation pad. Such a structure can completely insulate and block the distribution box body from the mounting plate, and the short-circuit current of the mounting plate will not be conducted to the distribution box body, achieving the purpose of insulation protection.

[0004] However, in the process of implementing the technical solution of the above patent, the electrical equipment is installed at a relatively deep position in the comprehensive distribution box. When the existing comprehensive distribution box is in use, to ensure the reasonable use of the space inside the distribution box, the mounting plate is set deep in the distribution box. After the electrical equipment is installed, the internal space of the distribution box becomes relatively crowded. When the electrical equipment has a leakage fault, it is necessary for the operator to reach into the distribution box to detect and repair. Due to the relatively crowded inside of the distribution box, it is easy for the operator to touch other electrical equipment when operating inside the distribution box, resulting in difficult leakage detection and repair work. And during normal ordinary operations, when the operator accidentally touches other electrical equipment, it is easy to cause the connection position of the electrical equipment to become loose, resulting in leakage. Content of the Utility Model

[0005] The purpose of the utility model is to provide an insulation protection device for a comprehensive distribution box to solve the above problems. It can push the electrical equipment out of the distribution box, so as to detect, repair and perform other ordinary operations on the electrical equipment in a relatively spacious space.

One side surface of each of the two anti-detachment sliders facing away from each other is fixedly connected with an anti-detachment rotating shaft. The two anti-detachment rotating shafts respectively penetrate through the two insulating connecting rods and are respectively rotatably connected with the two insulating connecting rods;

[0011] The above-mentioned square limiting rod penetrates through the U-shaped sliding frame and is slidably connected with the U-shaped sliding frame. The square limiting rod is adapted to the anti-detachment limiting guide frame. Two symmetrically arranged circular blocks are fixedly connected to the outer surface of the square limiting rod. Both of the two circular blocks are slidably connected to the inner wall of the hinge plate. Under the sliding action of the circular blocks and the hinge plate, when the hinge plate rotates in the hinge seat, it will drive the square limiting rod to move in the horizontal direction.

[0012] Furthermore, a second spring is fixedly connected to one side surface of the hinge plate close to the U-shaped sliding frame. The end of the second spring away from the hinge plate is fixedly connected to the outer surface of the U-shaped sliding frame. The setting of the second spring can push the hinge plate to reset after pressing the hinge plate.

[0029] An embodiment of the utility model provides an insulating protection device for a comprehensive distribution box.

[0030] Please refer specifically to Figure 1 、 Figure 3 and Figure 5 , including a comprehensive distribution box body 1.

Four L - shaped insulating sliding frames 8 are fixedly connected to the outer surface of the insulating moving plate 5. Four anti - detachment tracks 9 are fixedly connected to the inner wall of the comprehensive distribution box body 1. Through the arrangement of the insulating moving plate 5 and the L - shaped insulating sliding frames 8, the mounting plates 6 and the comprehensive distribution box body 1 are separated, thereby preventing the electrical equipment on the mounting plates 6 from leaking electricity to the comprehensive distribution box body 1 and causing electric shock to the operator. The four L - shaped insulating sliding frames 8 are respectively slidably connected to the inner walls of the four anti - detachment tracks 9. The L - shaped insulating sliding frames 8 and the anti - detachment tracks 9 play a guiding role in the movement of the insulating moving plate 5.

[0031] Please refer specifically to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , two symmetrical ejecting mechanisms 2 are arranged inside the comprehensive distribution box body 1. The ejecting mechanism 2 includes a rotating rod 22 rotatably connected to the inner wall of the comprehensive distribution box body 1 and two anti - detachment sliders 24 slidably connected to the inner wall of the insulating moving plate 5. A cabinet door 21 is fixedly connected to the outer surface of the rotating rod 22. Two symmetrical insulating connecting rods 23 are fixedly connected to the outer surface of the rotating rod 22. Anti - detachment rotating shafts 25 are fixedly connected to one side surfaces of the two anti - detachment sliders 24 away from each other. The two anti - detachment rotating shafts 25 respectively penetrate through the two insulating connecting rods 23 and are respectively rotatably connected to the two insulating connecting rods 23. When the insulating connecting rods 23 rotate, the insulating moving plate 5 can be driven to move through the anti - detachment rotating shafts 25 and the anti - detachment sliders 24.

[0032] Please refer specifically to Figure 1 、 Figure 3 and Figure 4 Above the integrated power distribution box body 1, a limiting mechanism 3 is provided. The limiting mechanism 3 includes a limiting seat 31 fixedly connected to the outer surface of the insulating moving plate 5 and a fixed pipe 32 fixedly connected to the upper surface of the integrated power distribution box body 1. An insulating limiting rod 33 is slidably connected to the inner wall of the fixed pipe 32. An inclined surface is provided on the insulating limiting rod 33. When the insulating moving plate 5 moves outwards, it can push the insulating limiting rod 33 upwards through the inclined surface of the insulating limiting rod 33. The insulating limiting rod 33 penetrates through the integrated power distribution box body 1 and is slidably connected to the integrated power distribution box body 1. The insulating limiting rod 33 and the limiting seat 31 are adapted to each other. When the insulating moving plate 5 moves to the outermost part, the insulating limiting rod 33 can be inserted into the limiting seat 31, thereby fixing the position of the insulating moving plate 5.

[0033] A operating plate 34 is fixedly connected to the top end of the insulating limiting rod 33. A first spring 35 is fixedly connected to the bottom surface of the operating plate 34. The bottom end of the first spring 35 is fixedly connected to the upper surface of the integrated power distribution box body 1. The first spring 35 is always in a stretched state, so that the insulating limiting rod 33 is always subjected to a downward force.

[0034] Please refer specifically to Figure 1 and Figure 6 On the outer surface of the insulating moving plate 5, two symmetrically arranged anti - detachment limiting guide frames 7 are fixedly connected. On the outside of each mounting plate 6, two symmetrically arranged adjusting mechanisms 4 are provided. The adjusting mechanism 4 includes a square limiting rod 45 and a U - shaped sliding frame 41 fixedly connected to the outer surface of the mounting plate 6. The U - shaped sliding frame 41 is slidably connected to the outer surface of the anti - detachment limiting guide frame 7. A hinge seat 42 is fixedly connected to the outer surface of the U - shaped sliding frame 41. An articulated plate 43 is hinged to the inner wall of the U - shaped sliding frame 41. The anti - detachment limiting guide frame 7 guides the up - and - down movement of the U - shaped sliding frame 41 and the mounting plate 6.

[0035] The above - mentioned square limiting rod 45 penetrates through the U - shaped sliding frame 41 and is slidably connected to the U - shaped sliding frame 41. The square limiting rod 45 is adapted to the anti - detachment limiting guide frame 7. A plurality of limiting holes adapted to the square limiting rod 45 are provided on the anti - detachment limiting guide frame 7. Inserting the square limiting rod 45 into the corresponding limiting hole of the anti - detachment limiting guide frame 7 can fix the U - shaped sliding frame 41. Two symmetrically arranged circular blocks 46 are fixedly connected to the outer surface of the square limiting rod 45. Both circular blocks 46 are slidably connected to the inner wall of the articulated plate 43. Under the sliding action of the circular blocks 46 and the articulated plate 43, when the articulated plate 43 rotates in the hinge seat 42, it will drive the square limiting rod 45 to move horizontally.

[0036] One side of the hinge plate 43 close to the U-shaped sliding frame 41 is fixedly connected with a second spring 44. The end of the second spring 44 away from the hinge plate 43 is fixedly connected to the outer surface of the U-shaped sliding frame 41. The setting of the second spring 44 can push the hinge plate 43 to reset after pressing the hinge plate 43.

[0037] Working principle: When opening two cabinet doors 21 synchronously, the insulating connecting rod 23 is driven to rotate around the rotating rod 22 through the rotating rod 22, so as to drive the anti-disengagement rotating shaft 25 and the anti-disengagement slider 24 to move. Under the sliding action of the L-shaped insulating sliding frame 8 and the anti-disengagement track 9, the insulating moving plate 5 is driven to move towards the outside of the integrated power distribution box body 1. At this time, the electrical equipment on the mounting plate 6 will move to the outside of the integrated power distribution box body 1. At the same time, the insulating moving plate 5 will push the insulating limiting rod 33 to move upward through the inclined surface of the insulating limiting rod 33. At this time, the first spring 35 is stretched. When the limiting seat 31 moves to directly below the insulating limiting rod 33, the insulating limiting rod 33 is pushed into the limiting seat 31 under the elastic force of the first spring 35, so that the position of the insulating moving plate 5 is fixed. Then, the electrical equipment on the mounting plate 6 can be subjected to leakage detection or other operations;

[0038] By pressing the bottom of the hinge plate 43, the second spring 44 is compressed, and the hinge plate 43 will drive the circular block 46 and the square limiting rod 45 to move away from the anti-disengagement limiting guide frame 7. Then, the U-shaped sliding frame 41 can be moved up and down. When the hinge plate 43 is released, under the elastic force of the compressed second spring 44, the hinge plate 43 is pushed to reset, and the square limiting rod 45 is inserted into the corresponding limiting hole of the anti-disengagement limiting guide frame 7 to complete the fixation of the mounting plate 6. This device can push the insulating moving plate 5, the mounting plate 6 and the electrical equipment out of the integrated power distribution box body 1 when the cabinet door 21 is opened, so that the electrical equipment can be subjected to leakage detection, maintenance and other general operations in a relatively spacious space.
