Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular is a dustproof dust cover for contact fingers of an isolating switch and a manufacturing method thereof. Background Art

[0002] Ensuring the stability of the power system in the high-altitude areas of western China is an important issue in the current power system. The most deployed and critical nodes in the power system are switchgear.

[0003] High-voltage disconnectors work in high-altitude environments, and their mechanical transmission mechanisms are exposed to various atmospheric environments for a long time, and are subject to erosion by wind, sand, rain and snow. Therefore, oxides and dust are easily accumulated at the switch transmission joints, which hinders the movement of the switch when it is opened or closed. If it cannot be discovered and repaired in time, it will cause operation jams, inadequate opening and closing, insulator breakage, loose contacts and heating, and eventually lead to failures. In order to avoid heating of contact fingers, the existing technology generally uses loop resistance testing to assist in judging the heating of GIS; directly measures the heating of GIS equipment through fiber Bragg grating temperature measurement and infrared temperature measurement; However, the above methods all simulate and monitor the temperature of the housing and contact fingers, and cannot directly eliminate the impact of wind dust, salt, alkali, oxides, dust and birds nesting on the contact fingers on the contact fingers. There are also dust covers on the disconnectors, but during operation, the disconnectors may produce a certain degree of deformation or vibration due to operation and environmental factors (such as wind vibration, thermal expansion and contraction caused by temperature changes), which may cause the dust cover mounted on the outside to shake and move. Therefore, a dustproof dust cover for the disconnector contact fingers and a method for making the same are proposed to solve the problems raised in the background technology.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any technician in the field to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details to obscure the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0022] Example 1 like Figures 1 to 6 As shown, the present invention provides a dust cover for contact fingers of a disconnecting switch that is dustproof, comprising a base 1, a dust cover body 2 is movably connected inside the base 1, a bidirectional threaded rod 3 is movably connected to the top of the inner cavity of the dust cover body 2, a slide plate 4 is slidably connected to both ends of the bidirectional threaded rod 3, a rotating assembly 5 and a moving assembly 6 are movably connected inside the slide plate 4, a second connecting rod 8 is fixedly connected at an equal angle in an annular manner on the surface of the slide plate 4, a clamping block 7 is hinged at one end of the second connecting rod 8 away from the slide plate 4, a lifting assembly 9 is movably connected inside the base 1, a switch body 12 is placed inside the base 1, and a cover plate 13 is provided at the end of the switch body 12; The rotating assembly 5 includes a rotating disk 51, a first arc groove 52 is formed in an annular manner at equal angles on the surface of the rotating disk 51, two symmetrical second arc grooves 53 are formed in an annular manner on the outer wall in the middle of the rotating disk 51, and four first connecting rods 54 are movably connected to the opposite sides of the two slide plates 4; The lifting assembly 9 includes a moving plate 91 , and inclined grooves 92 are formed on both sides of the moving plate 91 .

[0023] The above scheme is adopted: the turntable 51 is driven to rotate along the trajectory of the second arc groove 53 through the connecting column on the round rod 61, and then the first connecting rod 54 cooperates with the first arc groove 52, so that the first connecting rod 54 drives one end of the block 7 to move in the direction of the second connecting rod 8. The block 7 is made of silicone rubber material, so that the block 7 can adapt well to the dynamic changes of the contact fingers. The block 7 rotates around the second connecting rod 8 as the axis, and then after one end of the block 7 moves, it can drive the other end to rotate in the direction close to the cover plate 13 until the block 7 is engaged with the cover plate 13, thereby combining the entire device with the switch body 12, thereby preventing the device from shaking when the switch body 12 moves.

[0024] like Figures 3 to 5As shown, a protrusion that is movably engaged with the inside of the first arc groove 52 is provided on the side of the first connecting rod 54 close to the slide plate 4, and a straight groove is provided on the inner wall of the slide plate 4 for circumferentially limiting the protrusion. The end of the first connecting rod 54 close to the second connecting rod 8 is hinged to the block 7, and the curvature of the second arc groove 53 is sixty degrees. The movable component 6 includes a round rod 61, and the outer wall of the round rod 61 is provided with two connecting columns that are movably engaged with the inside of the second arc groove 53.

[0025] The above scheme is adopted: a straight groove is opened through the inner wall of the slide plate 4, and its function is that when the turntable 51 rotates, the straight groove limits the circumferential position of the protrusion on the first connecting rod 54, so that the protrusion can only drive the first connecting rod 54 to move axially toward the second connecting rod 8 along the trajectory of the first arc groove 52, thereby ensuring the normal operation of the device.

[0026] like Figures 3 to 5 As shown, the connecting column of the outer wall of the round rod 61 passes through the outer wall of the turntable 51 and extends to the outside of the turntable 51, one end of the connecting column of the round rod 61 is fixedly connected to a square block 62, one side of the square block 62 is fixedly connected to a spring plate 63, the square block 62 is elastically connected to the slide plate 4 through the spring plate 63, the round rod 61 passes through the outer wall of the slide plate 4 and extends to the outside of the slide plate 4, the block 7 is L-shaped, the block 7 rotates around the hinge with the second connecting rod 8 as the axis, the block 7 is made of silicone rubber material, the first connecting rod 54 moves toward the direction of the second connecting rod 8 and drives the block 7 to rotate, and the block 7 is engaged with the outer wall of the cover plate 13 after rotating.

[0027] The above solution is adopted: through the design of the spring piece 63, its function is that when the slide plate 4 drives the moving assembly 6 to move away from the cover plate 13, at this time, the square block 62 will drive the round rod 61 to reset under the elastic force of the spring piece 63, so as to facilitate the next use of the device; The clamping block 7 is made of silicone rubber material, and its function is that since the contact fingers of the switch body 12 will perform actions such as opening and closing during operation, the clamping block 7 clamped with the cover plate 13 may need to move accordingly. Since silicone rubber has excellent flexibility and can adapt well to such dynamic changes, it can expand and contract and bend within a large range and will not break due to repeated movement, thereby ensuring the normal operation of the device.

[0028] Example 2 like Figure 1 and Figure 6As shown, a first threaded rod 93 is movably connected to the middle of the movable plate 91, and the first threaded rod 93 is threadedly connected to the base 1. Round blocks 10 are fixedly connected to both sides of the dust cover body 2. The round block 10 is initially located at the bottom end of the inclined groove 92. The inner wall of the base 1 is provided with a sliding groove for limiting the round block 10 in the vertical direction. After the movable plate 91 moves, it drives the round block 10 to slide upward along the trajectory of the inclined groove 92. The base 1 and the dust cover body 2 are both made of epoxy glass insulating material. A second threaded rod 11 is threadedly connected to one side of the dust cover body 2, and a cross groove is provided inside the bidirectional threaded rod 3 near one end of the second threaded rod 11. A cross block movable in the cross groove is provided at one end of the second threaded rod 11. When the second threaded rod 11 rotates, it drives the bidirectional threaded rod 3 to rotate and slide inside the bidirectional threaded rod 3.

[0029] The above scheme is adopted: by rotating the first threaded rod 93, the first threaded rod 93 drives the movable plate 91 to move toward the inside of the base 1, and the round block 10 is movably connected to the inside of the inclined groove 92, so that after the movable plate 91 moves, the round block 10 is driven to slide along the track of the inclined groove 92, and then, under the action of the limit of the sliding groove on the inner wall of the base 1, the round block 10 can only drive the dust cover body 2 to move upward, so as to achieve the height adjustment of the whole device, thereby improving the practicality and convenience of the whole device; The base 1 and the dust cover body 2 are both made of epoxy glass insulation material. The epoxy glass insulation material can maintain stable insulation performance under complex electrical conditions such as different voltage levels, frequencies and electric field distributions. Whether in industrial frequency alternating current or in some special high-frequency electrical environments, epoxy glass can effectively prevent current from passing through the dust cover, thereby ensuring the electrical insulation integrity of the disconnector; Epoxy glass insulation material has high strength and hardness, and can provide sufficient structural support for the dust cover. In outdoor environments, the dust cover may be affected by various external forces, such as strong winds, mechanical vibrations, ice and snow accumulation, etc. The use of epoxy glass material can effectively resist these external forces and prevent the dust cover from deformation and damage. At the same time, epoxy glass insulation material can also resist thermal aging. In long-term high temperature environments, many materials will gradually lose their performance due to thermal aging, but epoxy glass materials can maintain stable performance in a certain degree of high temperature environment, avoiding problems such as material embrittlement and decreased insulation performance due to thermal aging.

[0030] The working principle and use process of the present invention are as follows: the operator adjusts the height of the entire device according to different switch bodies 12, and drives the movable plate 91 to move toward the inside of the base 1 by rotating the first threaded rod 93. When the movable plate 91 moves, the round block 10 is movably engaged with the inside of the inclined groove 92, so that the round block 10 drives the dust cover body 2 to move upward along the track of the inclined groove 92, thereby realizing the height adjustment of the entire device; Subsequently, the switch body 12 is placed inside the base 1. At this time, the operator rotates the second threaded rod 11, thereby driving the two-way threaded rod 3 to rotate through the cooperation between the second threaded rod 11 and the cross groove, thereby causing the two slides 4 to move toward each other along the trajectory of the two-way threaded rod 3. While the slide 4 moves, it drives the rotating assembly 5 and the moving assembly 6 inside it to move together. When the slide 4 drives the round rod 61 to abut against the outer wall of the cover plate 13, the round rod 61 is forced to move toward the inside of the slide 4, thereby driving the connecting column and the square block 62 to move together, thereby causing the connecting column to drive the turntable 51 to rotate along the trajectory of the second arc groove 53. While the turntable 51 rotates, the first connecting rod 54 protrusion cooperates with the first arc groove 52, thereby causing the protrusion to drive the first connecting rod 54 to move toward the direction of the second connecting rod 8 along the trajectory of the first arc groove 52, thereby causing the first connecting rod 54 to drive one end of the block 7 to move together; After the first connecting rod 54 drives one end of the block 7 to move, the block 7 rotates around the second connecting rod 8 as the axis, thereby causing the other end of the block 7 to rotate toward the cover plate 13. When the round rod 61 is completely retracted into the slide plate 4, the block 7 is engaged with the cover plate 13, thereby combining the device with the switch body 12, thereby preventing the device from shaking or wobbling when the switch body 12 moves, thereby ensuring the normal operation of the device.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
