Description

Technical Field

[0001] The invention relates to the technical field of insulation pad performance testing, in particular to an adjustable insulation pad test bench. Background Art

[0002] Insulation mats are safety devices used for electrical insulation protection, primarily to prevent electric shock, equipment short circuits, and arcing. They are widely used in substations, distribution rooms, laboratories, and industrial equipment. Conductive testing of insulation mats is crucial. Regular field testing is required to ensure they are non-conductive or have sufficient resistance to prevent current leakage or short circuits, ensuring worker safety.

[0003] At present, field tests are often completed by using portable insulation pad test equipment, four insulation piers, and two fixed-size iron plates. However, due to the fixed size of the iron plates, the limited number of insulation piers, and the limited range of the test base, it is necessary to complete the insulation pad test of a longer length through segmented and multiple tests. The overall test efficiency is low. At the same time, each time the experimental operation is carried out, the equipment carried is too much and inconvenient to carry, and it takes up a lot of space.

[0004] There are also portable tooling in the prior art that aims to solve the problem of having to carry a lot of equipment and taking up a lot of space for each test. For example, the Chinese invention patent with publication number CN217085170U discloses a portable insulating pad detection and testing tool. The detection and testing tool includes a detection and testing platform, a support module installed on the detection and testing platform, and a grounding module connected to the support module for grounding. The detection and testing platform is provided with a first folding component for folding and storing inside, and the support module is provided with a second folding component for folding and storing with the detection and testing platform on the outside. The detection and testing tool can be folded and stored by the first folding component and the second folding component. At the same time, the high-voltage electrode module used can also be used in combination according to the size of the insulating pad, solving the technical problems in the prior art that the detection and testing tool is not convenient for folding and storing, which makes it inconvenient to carry, and is not convenient for testing insulating pads of different sizes.

[0005] Although the above-mentioned test tooling can be folded and stored, the surface for placing the insulating pads it provides is still very limited. For insulating pads with longer lengths, segmented and multiple tests are still required; secondly, the high-voltage electrode module needs to be selected in an appropriate size according to the size of the insulating pad, that is, high-voltage electrode modules of different specifications need to be carried during a single test. If multiple test tools are spliced ​​together to adapt to longer insulating pads, several test tools need to be carried, and the corresponding number of high-voltage electrode modules carried will also increase. In this way, a lot of space will be taken up in the transport engineering vehicle and the test site, and because each test tooling is composed of many parts, the overall size is large and the weight is heavy, it will cause inconvenience in carrying, transporting, and on-site assembly.

[0006] Therefore, it is necessary to provide an adjustable insulation pad test bench to solve the problem that it is difficult to adjust the size of the test base according to the length of the insulation pad. The test of insulation pads with longer lengths needs to be completed through segmented and multiple tests. The overall test efficiency is low, and each on-site test requires carrying a lot of equipment that takes up a lot of space and is heavy. Summary of the Invention

[0007] In order to solve the above problems, the present invention provides an adjustable insulation pad test bench, including a number of basic insulation boards and extended insulation boards, a number of common insulation boards, end clips, flexible silicone pads, and right-angle supports. A number of plug-in slots are provided on the basic insulation boards and the extended insulation boards; the length of the extended insulation boards is greater than that of the basic insulation boards; a number of joint slots are provided on the common insulation boards; a number of basic insulation boards and common insulation boards are assembled into a cube grid structure through vertical plug-in slots and joint slots, and the basic insulation boards and common insulation boards are mutually restricted in the front, back, left, and right directions; a number of extended insulation boards and common insulation boards are assembled into a rectangular grid structure through vertical plug-in slots and joint slots, and the extended insulation boards and common insulation boards are mutually restricted in the front, back, left, and right directions. They are limited to each other in the right direction; right-angle supports are provided on both the basic insulating board and the extended insulating board, and the right-angle supports are used to implement triangular support and fixation on the four inner right-angle parts of the cells in the grid structure; the right-angle supports complete the support at the same time as the grid structure is assembled; the end clips are provided on one side of the extended insulating board; when the two rectangular grid structures are spliced ​​in the length direction of the extended insulating board, the end clips connect and fix the two adjacent extended insulating boards; during the test, the insulating pad is laid flat on the assembled grid structure, and the flexible silicone pad is laid on the insulating pad.

[0008] Preferably, the plug-in slot and the engaging slot are both composed of a trumpet-shaped section and a vertical section, wherein the trumpet-shaped section on the engaging slot and the trumpet-shaped section on the plug-in slot are distributed vertically up and down, and the trumpet-shaped section is used to guide the vertical plug-in fitting process.

[0009] Preferably, the right-angle support member includes a mounting seat and a reinforcement plate, the mounting seat is arranged on the basic insulation board / extended insulation board; the reinforcement plate is hingedly mounted on the mounting seat; when the grid structure is assembled, the non-hinged end of the reinforcement plate contacts the inner wall of the corresponding cell and forms a triangular structure with the corresponding inner right-angle portion.

[0010] Preferably, the right-angle support further comprises a limiting portion vertically disposed on the mounting base for limiting the rotation angle of the reinforcement plate. The limiting portion is a vertical column with a limiting end, which is slidably connected to the mounting base up and down, and the limiting end is located within the mounting base. When the vertical column moves upward to a maximum displacement, the limiting end is located above the reinforcement plate, and the rotation angle restriction of the reinforcement plate is released.

[0011] Preferably, the end clamp is composed of symmetrically arranged elastic clamps. When the end of the extended insulating plate is inserted between the symmetrical elastic clamps, the elastic clamp is elastically deformed. After the end of the extended insulating plate is inserted, the elastic clamp is pressed against the side of the extended insulating plate under the action of its own elastic force.

[0012] Preferably, the elastic clamping plate is composed of an inclined section and a curved section, the curved section is connected to the corresponding extended insulating plate, and the inclined sections of the symmetrical elastic clamping plates form an eight-shaped structure with the large-diameter end away from the curved section.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention adopts an assembled modular test base formed by plugging and assembling a simple and lightweight plate structure to replace several traditional insulating piers, and the size of the assembled modular test base can be adjusted on-site according to the size of the insulating pad, and a flexible silicone pad that can be freely rolled and folded and has excellent conductive properties is used to replace the iron plate with a fixed size. The flexible silicone pad can be adjusted arbitrarily according to the size of the insulating pad. At the same time, the concept of component sharing is adopted to ensure that the size of the assembled modular test base is adjustable, thereby reducing the components required to be carried and reducing the total weight of the equipment required to be carried.

[0014] 2. The present invention utilizes a cube-shaped grid structure assembled by vertically plugging together basic insulating panels and common insulating panels. These panels are mutually constrained in the front, rear, left, and right directions, making it suitable for testing single insulating pads for individual electrical cabinets. Furthermore, extended insulating panels and common insulating panels are vertically plugged together to form a rectangular grid structure. These panels are mutually constrained in the front, rear, left, and right directions, making it suitable for testing long, large insulating pads for rows of electrical cabinets. This eliminates the need for segmented or multiple tests. The grid structure is formed through a simple plug-in operation, allowing for rapid assembly. Furthermore, the basic insulating panels, common insulating panels, and extended insulating panels are easy to stack and carry, taking up minimal space.

[0015] 3. The grid structure assembled by the present invention has the advantages of high strength, light weight and uniform load distribution, which can ensure that the insulating pad is tested in a continuously stable state. At the same time, right-angle supports are added to the basic insulating board and the extended insulating board. When the grid structure is assembled, triangular supports are automatically implemented on the inner right-angle parts of the cells in the grid structure. There is no need to complete it in steps or through a complex structure, thereby further improving the structural strength and stability of the grid structure.

[0016] 4. The present invention utilizes end clips to splice and fix independent rectangular grid structures, further expanding the length range of adaptable insulating pads. At the same time, the basic insulating board and the extended insulating board are set to be inconsistent only in length, that is, two lengths of plate structures are adopted. Compared with the conductive performance test of insulating pads adapted to rows of electrical cabinets by splicing together several cube grid structures and end clips, the number of plate structures required for the use of rectangular grid structures and end clips is small, the construction efficiency is relatively high, and it caters to the concept of component sharing.

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 9 The present invention uses an assembled modular test base consisting of a basic insulating plate 1 and a common insulating plate 3 or an extended insulating plate 2 and a common insulating plate 3 to replace several traditional insulating piers. The basic insulating plate 1, the common insulating plate 3, and the extended insulating plate 2 are all lightweight epoxy resin insulating plates. The flexible silicone pad 6 in the present invention is a flexible graphite nickel-plated silicone pad with excellent electrical conductivity. The graphite nickel-plated silicone pad is used to replace the traditional iron plate. The graphite nickel-plated silicone pad can be rolled up and folded to adjust the length at will. Both the assembled modular test base and the flexible conductive silicone pad can be built and adjusted on-site according to the length of the insulating pad. It is convenient, fast and easy to carry, and can complete a one-time electrical conductivity test of the entire insulating pad. Specifically:

[0031] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 9The present invention provides an adjustable insulation pad test bench, comprising: a basic insulation board 1, an extended insulation board 2, a common insulation board 3, a right-angle support 4, an end clamp 5, and a flexible silicone pad 6. The lower ends of the basic insulation board 1 and the extended insulation board 2 are each provided with a plurality of plug-in slots 10 arranged linearly along the length direction, and the basic insulation board 1 and the extended insulation board 2 are both provided with a right-angle support 4. The upper end of the common insulation board 3 is provided with a plurality of joint slots 30 arranged linearly along its length direction. The number of joint slots 30 on a single common insulation board 3 is greater than the number of plug-in slots 10 on a single basic insulation board 1 and an extended insulation board 2. The basic insulation board 1, the extended insulation board 2, and the common insulation board 3 are all provided with a plurality of pieces, and the length of the extended insulation board 2 is greater than that of the basic insulation board 1. The basic insulation board 1, the extended insulation board 2, and the common insulation board 3 are all thin plate structures with the same performance, material, and thickness.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 9 Several basic insulation panels 1 and common insulation panels 3 are assembled vertically through insertion slots 10 and joint slots 30 to form a cubic grid structure (i.e., a modular test platform). The four sides of the cubic grid structure do not form semi-enclosed cells. Several extended insulation panels 2 and common insulation panels 3 are assembled vertically through insertion slots 10 and joint slots 30 to form a rectangular grid structure (i.e., a modular test platform). The four sides of the rectangular grid structure also do not form semi-enclosed cells. Upon completion of the grid structure assembly, right-angle supports 4 provide triangular support at the four inner right angles of the cells in the grid structure.

[0033] When building and assembling a modular test base on site, choose to build a cube grid structure or a rectangular grid structure according to the actual test method. For example, when conducting a conductivity test of the insulation pad of a separate electrical cabinet, since there is only a single and small-sized insulation pad, a cube grid structure (such as Figure 4 As shown in the figure, the cube grid structure is assembled by three basic insulating boards 1 and three common insulating boards 3. When conducting the conductivity test of the insulating pads of the electrical cabinets in a row, since the insulating pads are mostly long strips, a rectangular grid structure (such as Figure 6As shown, the rectangular grid structure is assembled from four linearly distributed common insulating plates 3 and two extended insulating plates 2. If the insulating pad is heavy, three extended insulating plates 2 can also be used simultaneously. If the length of the insulating pad requires multiple rectangular grid structures, two adjacent rectangular grid structures can be docked and fixed via end clamps 5 to accommodate longer insulating pads. In addition, compared to the conductive performance test of insulating pads adapted for rows of electrical cabinets using several cube grid structures combined with end clamps 5, the use of rectangular grid structures combined with end clamps 5 requires fewer plates, which improves construction efficiency. Therefore, the present invention uses extended insulating plates 2 and base insulating plates 1 that differ only in length.

[0034] See also Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 An end clip 5 is provided on one side of the extended insulating plate 2 and is comprised of symmetrically arranged elastic clips 50. The right-angle support member 4 includes a mounting base 40 provided on the base insulating plate 1 / extended insulating plate 2, and a stopper vertically disposed on the mounting base 40. The stopper is used to limit the rotation angle of the reinforcement plate 41. The reinforcement plate 41 is hingedly connected to the mounting base 40, and a rubber pad is provided on the end surface of the reinforcement plate 41 facing away from the mounting base 40.

[0035] See also Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 Taking the construction process of a cube grid structure as an example, the specific construction process is as follows: the assembler aligns the plug-in slot 10 on the basic insulating board 1 with the joint slot 30 on the common insulating board 3, and then vertically plugs the basic insulating board 1 into the vertically placed common insulating board 3 from top to bottom. At this time, the solid part of the joint slot 30 on the lower side of the common insulating board 3 is located in the plug-in slot 10, and the solid part of the basic insulating board 1 on the upper side of the plug-in slot 10 is located in the joint slot 30, and the upper and lower end surfaces of the basic insulating board 1 and the common insulating board 3 are flush (as shown in FIG. Figure 4 As shown), in this state, the basic insulating board 1 and the common insulating board 3 limit each other in the front, rear, left and right directions. One basic insulating board 1 is plugged into three common insulating boards 3 at a time, and the plug-in installation of the remaining basic insulating boards 1 is completed according to the above operation process.

[0036] Furthermore, during the top-down insertion of the basic insulating plate 1 onto the common insulating plate 3, the assembler rotates the reinforcing plate 41 until it contacts the stopper. The basic insulating plate 1, via the inverted U-shaped bracket 43, drives the mounting base 40 and reinforcing plate 41 downward in a synchronous manner. The reinforcing plate 41 moves toward the inner right-angled portion of the grid cell, and the rubber pad on the reinforcing plate 41 moves downward along the side of the common insulating plate 3. Finally, when the cube grid structure is assembled, the reinforcing plate 41 cannot rotate because its rotation angle is limited by the stopper and the rubber pad on the reinforcing plate 41 contacts the side of the common insulating plate 3. Consequently, the reinforcing plate 41 forms a stable triangular structure with the inner right-angled portion of the cell, enhancing the overall structural strength and stability of the cube grid structure. This in turn improves the cube grid structure's resistance to the graphite nickel-plated silicone pads and insulating pads, thereby ensuring that the insulating pads remain stable during the conductivity test.

[0037] The construction process of the rectangular grid structure is the same as that of the cube grid structure, and will not be repeated here. If two rectangular grid structures need to be spliced ​​in the length direction of the extended insulating plate 2, it is only necessary to insert the end of the extended insulating plate 2 between the symmetrical elastic clips 50 at the ends of adjacent extended insulating plates 2. During the insertion process, the elastic clip 50 undergoes adaptive elastic deformation until the ends of the two extended insulating plates 2 collide with each other. At this time, the elastic clip 50 is pressed against the side of the extended insulating plate 2 under the action of its own elastic force.

[0038] During the conductivity test, first lay the insulating pad flat on the assembled modular test base, then lay the graphite nickel-plated silicone pad on the insulating pad, and adjust the length of the graphite nickel-plated silicone pad according to the length of the insulating pad. Then use the existing test equipment to apply 15kV to one end of the graphite nickel-plated silicone pad, and use a voltage divider to monitor the voltage at the other end. If the voltage is still 15kV, it indicates that the insulation pad has good conductivity and meets the requirements.

[0039] See also Figure 1 、 Figure 2 and Figure 3 To improve the efficiency and smoothness of constructing a cube or rectangular grid structure, the following configuration is implemented: both the insertion slots 10 and the joint slots 30 consist of a bell-shaped section and a vertical section. The bell-shaped sections of the joint slot 30 and the insertion slot 10 are vertically arranged in an upper and lower direction. Specifically, the bell-shaped sections of the insertion slot 10 are located below the corresponding vertical sections, while the bell-shaped sections of the joint slot 30 are located above the corresponding vertical sections. During the vertical insertion of the base insulation board 1 / extended insulation board 2 onto the common insulation board 3, the bell-shaped sections guide the insertion and mating process, allowing assemblers to quickly align the insertion slot 10 and joint slot 30.

[0040] See also Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 , the right-angle support member 4 also includes a hanging portion fixedly connected to the mounting seat 40; the basic insulating plate 1 and the extended insulating plate 2 are both detachably connected to the corresponding hanging portion. The hanging portion is an inverted C-shaped frame 43, and the mounting seat 40 is fixedly connected to the vertical section of the corresponding inverted C-shaped frame 43. Both the basic insulating plate 1 and the extended insulating plate 2 are provided with a snap-in groove for the horizontal section of the inverted C-shaped frame 43 to be snap-fitted and installed. The right-angle support member 4 has two specifications. The difference between the two different specifications of the right-angle support members 4 is only the number of mounting seats 40. The mounting seats 40 correspond one-to-one to the reinforcing plates 41. In one specification of the right-angle support member 4, the inverted C-shaped frame 43 has only one vertical section with the mounting seat 40 installed (such as Figure 9 As shown), the two vertical sections of the inverted U-shaped frame 43 in another specification of the right-angle support member 4 are both equipped with a mounting seat 40 (as shown Figure 9 shown).

[0041] Of the three base extension plates that comprise the cube grid structure, the inverted C-shaped brackets 43 on the two side base extension plates have mounting blocks 40 installed on only one vertical segment, and this mounting block 40 is located within the corresponding cell. On the center base extension plate, however, both vertical segments of the inverted C-shaped bracket 43 are fitted with mounting blocks 40. This arrangement ensures that the inner right angles of the cells of the cube grid structure are all supported while also reducing the number of right-angle supports 4. This, in turn, reduces component costs and the total weight of the base extension plates and their respective right-angle supports 4, making them easier to carry.

[0042] If three extended insulating plates 2 and four common insulating plates 3 are used to build a rectangular grid structure (such as Figure 11 As shown in FIG, three extended insulating plates 2 are arranged at equal intervals. The extended insulating plates 2 on both sides still use the original right-angle support members 4 of the corresponding specifications. The original right-angle support member 4 on the extended insulating plate 2 in the middle is removed, and the right-angle support member 4 with the mounting seat 40 installed on both vertical sections of the inverted U-shaped frame 43 is installed on the extended insulating plate 2 in the middle (as shown in FIG. Figure 11 As shown), this ensures that several cells of the rectangular grid structure can all receive internal right-angle supports. At the same time, by setting up some shared parts, it can reduce the cost of parts and facilitate portability.

[0043] like Figure 10As shown, if a rectangular grid structure is constructed using two extended insulating plates 2 and four common insulating plates 3, and the distance between the two extended insulating plates 2 is small (to accommodate narrow, elongated insulating pads), all the right-angle supports 4 on the extended insulating plates 2 are replaced with right-angle supports 4 with mounting brackets 40 mounted on both vertical sections of the inverted C-shaped bracket 43. Replacing the right-angle supports 4 requires only the simple removal of the horizontal section of the inverted C-shaped bracket 43, without requiring complex operations.

[0044] See also Figure 4 、 Figure 5 、 Figure 6 、 Figure 10 and Figure 11 In order to facilitate the stacking of the extended insulating board 2 and the basic insulating board 1, reduce the occupied space and facilitate carrying, the following settings are made: the limiting part is a vertical column 42 with a limiting end, the vertical column 42 is slidably connected to the mounting seat 40 up and down, and the limiting end is located inside the mounting seat 40; before stacking the extended insulating board 2 and the basic insulating board 1, when the vertical column 42 is moved up to the maximum displacement position, the limiting end is located between the upper end of the reinforcing plate 41 and the inner top wall of the mounting seat 40, the rotation angle limit of the reinforcing plate 41 is released, and then the reinforcing plate 41 is rotated to make it contact the extended insulating board 2 / basic insulating board 1, and then the extended insulating board 2 / basic insulating board 1 can be placed horizontally with the side connected to the mounting seat 40 facing downward. At this time, the mounting seat 40 serves as the placement fulcrum of the extended insulating board 2 / basic insulating board 1. In addition, when the extended insulating plate 2 is in a horizontal state and the side connected to the mounting seat 40 faces downward, the linear distance between the lower end surface of the corresponding mounting seat 40 and the lower end surface of the extended insulating plate 2 is greater than the maximum linear distance between the lower end surface of the extended insulating plate 2 and the elastic clamping plate 50 located at the lower side (see Figure 11 ), therefore, the mounting base 40 still serves as a support for placing the extended insulating plate 2, and the elastic clip 50 does not serve as a force support, so as to avoid the elastic clip 50 being subjected to additional deformation when the extended insulating plate 2 and the basic insulating plate 1 are stacked, thereby affecting its use function.

[0045] When two extended insulating plates 2 and four common insulating plates 3 are used to build a rectangular grid structure, the distance between the two extended insulating plates 2 is relatively large. Therefore, in order to improve the effect of the reinforcing plate 41 on improving the structural strength of the rectangular grid structure, the length of the reinforcing plate 41 corresponding to the extended insulating plate 2 is set to be greater than the length of the reinforcing plate 41 corresponding to the basic insulating plate 1 (e.g., Figure 6 ), thereby increasing the size of the stable triangular structure formed.

[0046] See also Figure 6 and Figure 7The elastic clip 50 consists of an inclined section and a curved section. The curved section is connected to the corresponding extended insulating plate 2. The inclined sections of the symmetrical elastic clip 50 form an "eight" structure between them, with the larger end facing away from the curved section. This "eight" structure guides the insertion of the ends of the extended insulating plates 2, facilitating quick and smooth insertion between the symmetrical elastic clips 50. The curved sections of the elastic clip 50 are mounted with abutment plates, which are removably attached to the side of the corresponding extended insulating plate 2 using plastic screws (plastic screws are conventional). The removable design of the elastic clip 50 facilitates subsequent replacement.

[0047] It should be noted that, in the present invention, all components except the flexible silicone pad 6 are made of lightweight and non-conductive materials.
