Technical Field
[0001] This utility model relates to the field of high-voltage testing technology for electrical equipment, and in particular to an insulation device suitable for high-voltage testing of densely arranged electrical equipment. Background Technology
[0002] High-voltage testing of electrical equipment is a crucial step in ensuring the safe operation of power systems. By simulating high-voltage operating conditions, it tests the insulation performance, mechanical strength, and electrical parameters of equipment, allowing for the timely detection of potential defects. High-voltage testing is a core method for power equipment testing and must be strictly followed in accordance with standardized procedures. It requires combining equipment principles with data comparison and analysis to ensure the safe and reliable operation of the power system.
[0003] In existing technologies, during high-voltage testing of electrical equipment, the equipment is often densely packed, making it difficult to achieve stable insulation isolation between different devices based on their specifications. This can lead to mutual interference between different devices under high-voltage conditions, posing certain safety hazards. Therefore, this invention designs an insulation device suitable for high-voltage testing of densely arranged electrical equipment. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the prior art by proposing an insulation device suitable for high-voltage testing of densely arranged electrical equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An insulation device suitable for high-voltage testing of densely arranged electrical equipment includes a base plate and a support. The support is fixedly connected to the upper surface of the base plate. A lead screw is rotatably connected inside the support. A motor is fixedly connected to the top of the support. The output shaft of the motor is fixedly connected to the top of the lead screw. A movable block is threadedly connected to the wall of the lead screw. The movable block is slidably disposed on the inner wall of the support. A folded insulating plate is fixedly connected to the bottom of the movable block. A connecting plate is fixedly connected to the side wall of the movable block. A fixing rod is fixedly connected to the inner wall of the connecting plate. An adjusting insulating plate is movably sleeved on the wall of the fixing rod.
[0006] Preferably, an insulating rubber pad is fixedly connected to the side wall of the adjusting insulating plate.
[0007] Preferably, a sector gear is fixedly connected to the side wall of the adjusting insulating plate, and rectangular openings are respectively provided on both sides of the movable block. A rack is slidably provided on the inner wall of the rectangular opening of the movable block, and the rack and sector gear are meshed with each other.
[0008] Preferably, a threaded ring is fixedly connected to the inner wall of the top of the movable block, a screw is threadedly connected to the inner wall of the threaded ring, the bottom wall of the screw is rotatably connected to the inner wall of the rack, and a handle is fixedly connected to the top of the screw.
[0009] Preferably, the movable block has a guide groove on the inner wall of the rectangular opening, and a guide slider is fixedly connected to the side wall of the rack, and the guide slider is slidably disposed on the inner wall of the guide groove.
[0010] Preferably, the end of the adjusting insulating plate facing away from the fixed rod has a weight-reducing notch.
[0011] Compared with the prior art, this utility model provides an insulation device suitable for high-voltage testing of densely arranged electrical equipment, which has the following beneficial effects: 1. This insulation device is suitable for high-voltage testing of densely arranged electrical equipment. After the motor is started, it drives the lead screw to rotate. The movable block moves up and down along the inner wall of the bracket due to the screw drive. The vertical height of the folded insulation plate can be precisely adjusted to meet the insulation isolation requirements of electrical equipment at different heights. The folded insulation plate is made of foldable insulation material. It automatically unfolds or folds when the movable block rises and falls. When rising, the folded insulation plate naturally unfolds due to gravity to form a vertical insulation barrier. When falling, the folded insulation plate gradually folds, reducing the space occupied by the device.
[0012] 2. This insulation device, applicable to high-voltage testing of densely arranged electrical equipment, converts linear motion into rotational motion of the adjusting insulation plate through the meshing of a rack and a sector gear. When the rack moves upward, the sector gear drives the adjusting insulation plate to rotate inward, reducing the insulation isolation range. When the rack moves downward, the adjusting insulation plate rotates outward, expanding the insulation coverage area. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example 1 Reference Figure 1-3 An insulation device suitable for high-voltage testing of densely arranged electrical equipment includes a base plate 1 and a support 2. The support 2 is fixedly connected to the upper surface of the base plate 1. A lead screw 3 is rotatably connected inside the support 2. A motor 4 is fixedly connected to the top of the support 2. The output shaft end of the motor 4 is fixedly connected to the top of the lead screw 3. A movable block 5 is threadedly connected to the wall of the lead screw 3. The movable block 5 is slidably disposed on the inner wall of the support 2. A folded insulating plate 6 is fixedly connected to the bottom of the movable block 5. A connecting plate 7 is fixedly connected to the side wall of the movable block 5. A fixing rod 8 is fixedly connected to the inner wall of the connecting plate 7. An adjusting insulating plate 9 is movably sleeved on the wall of the fixing rod 8. An insulating rubber pad 10 is fixedly connected to the side wall of the adjusting insulating plate 9. A weight-reducing notch is opened at the end of the adjusting insulating plate 9 away from the fixing rod 8. A sector gear 11 is fixedly connected to the side wall of the adjusting insulating plate 9. Rectangular openings are opened on both sides of the movable block 5. A rack 12 is slidably disposed on the inner wall of the rectangular opening of the movable block 5. The rack 12 and the sector gear 11 are meshed with each other.
[0017] After the motor 4 starts, it drives the lead screw 3 to rotate. The movable block 5 moves up and down along the inner wall of the bracket 2 due to the threaded transmission, which can precisely adjust the vertical height of the folded insulating plate 6 to meet the insulation and isolation requirements of electrical equipment of different heights.
[0018] The rack 12 meshes with the sector gear 11, converting linear motion into rotational motion of the adjusting insulation plate 9. When the rack 12 moves upward, the sector gear 11 drives the adjusting insulation plate 9 to rotate inward, reducing the insulation isolation range. When the rack 12 moves downward, the adjusting insulation plate 9 rotates outward, expanding the insulation coverage area.
[0019] The foldable insulating plate 6 is made of foldable insulating material and automatically unfolds or folds when the movable block 5 rises and falls. When it rises, the foldable insulating plate 6 unfolds naturally due to gravity to form a vertical insulating barrier. When it falls, the foldable insulating plate 6 folds gradually to reduce the space occupied by the device.
[0020] The angle of the adjusting insulation plate 9 is adjusted by the sector gear 11, which, together with the folding insulation plate 6, forms a three-dimensional insulation protection. The insulating rubber pad 10 is attached to the surface of the equipment to fill the gaps and prevent the high-voltage arc from breaking down along the contact surface.
[0021] Example 2 Reference Figure 1-3An insulation device suitable for high-voltage testing of densely arranged electrical equipment includes a threaded ring 13 fixedly connected to the inner wall of the top of a movable block 5, a screw 14 threadedly connected to the inner wall of the threaded ring 13, the bottom end of the screw 14 rotatably connected to the inner wall of a rack 12, a handle 15 fixedly connected to the top of the screw 14, a guide groove provided on the inner wall of the movable block 5 located at a rectangular opening, and a guide slider 16 fixedly connected to the side wall of the rack 12, the guide slider 16 being slidably disposed on the inner wall of the guide groove.
[0022] Rotating the handle 15 drives the screw 14 to rotate, and the screw 14 can push the rack 12 to slide stably within the rectangular opening. The cooperation between the guide slider 16 and the guide groove prevents the rack 12 from deviating and ensures the accuracy of angle adjustment.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
