Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to a testing platform for a handcart-type circuit breaker. Background Technology

[0002] Switchgear is a crucial component of power systems, and truck-mounted circuit breakers are an important part of switchgear. Typically, the truck-mounted circuit breaker needs to be assembled before being placed into the switchgear cabinet. This requires precise dimensions of all components on the truck-mounted circuit breaker for successful assembly. For example, significant dimensional errors in the contact arms of the truck-mounted circuit breaker can lead to poor contact between the stationary and moving contacts.

[0003] Therefore, it is necessary to inspect the assembly results of the handcart circuit breaker. Utility Model Content

[0004] In view of this, the present invention proposes a testing platform for a handcart-type circuit breaker, comprising:

[0005] Base;

[0006] The first frame is vertically disposed on the base;

[0007] The first mounting plate can be fixed to the first frame;

[0008] The first stationary contact group includes a plurality of upper stationary contacts. The first stationary contact group can be fixed to the first mounting plate, and the position of at least one of the upper stationary contacts on the first mounting plate is adjustable.

[0009] The second mounting plate can be fixed to the first frame;

[0010] The second stationary contact group includes a plurality of lower stationary contacts. The second stationary contact group can be fixed to the second mounting plate, and the position of at least one of the lower stationary contacts on the second mounting plate is adjustable.

[0011] Two slide rail assemblies are provided, and the base is capable of supporting the two slide rail assemblies. The handcart-type circuit breaker can slide close to the first stationary contact group and the second stationary contact group via the slide rail assemblies. The distance between the two slide rail assemblies is adjustable.

[0012] By setting up adjustable stationary contact assemblies and slide rail components, the assembly results of handcart-type circuit breakers can be inspected. This method is not only highly efficient but also allows for rapid detection of which structural components may be faulty. Furthermore, this inspection platform is compatible with various models of handcart-type circuit breakers, demonstrating strong versatility.

[0013] Optionally, according to the detection platform described above, the first stationary contact group includes three upper stationary contacts in a row, with the middle upper stationary contact fixed and the two side upper stationary contacts adjustable; and / or the second stationary contact group includes three lower stationary contacts in a row, with the middle lower stationary contact fixed and the two side lower stationary contacts adjustable. In this way, for a three-phase trolley circuit breaker, only the two side contacts need to be adjusted, thus improving the efficiency of stationary contact adjustment.

[0014] Optionally, according to the testing platform described above, the first frame is provided with several mounting holes, through which the first mounting plate and the second mounting plate can be fixed to the first frame. This fixing method is convenient to assemble and has low cost.

Furthermore, adjusting the position via the mounting holes is not only highly accurate but also relatively simple to implement.

[0016] Optionally, based on the detection platform described above, it may also include:

[0017] A first lifting mechanism, connected to the first mounting plate, is used to adjust the height of the first mounting plate in a direction perpendicular to the base; and / or

[0018] The second lifting mechanism, connected to the second mounting plate, is used to adjust the height of the second mounting plate in the direction perpendicular to the base. By first adjusting each mounting plate to its corresponding position using the lifting mechanism, and then fixing the position through the mounting holes, it is not only time-saving and labor-saving, but also highly accurate and relatively simple to implement.

[0019] Optionally, according to the testing platform described above, each of the upper stationary contacts is detachably fixed to the first mounting plate, and each of the lower stationary contacts is detachably fixed to the second mounting plate.

[0020] Optionally, according to the testing platform described above, the first mounting plate and the second mounting plate are provided with several fixing holes. The upper stationary contact can be adjusted to a position on the first mounting plate through the fixing holes, and the lower stationary contact can be adjusted to a position on the second mounting plate through the fixing holes. This allows for the replacement of the stationary contact, thereby making the testing platform more versatile.

[0021] Optionally, according to the detection platform described above, the first frame is provided with a first guide rail, which is perpendicular to the base, and the first mounting plate and the second mounting plate can slide along the first guide rail; and / or the base is provided with a second guide rail, and the slide rail assembly can slide along the second guide rail to adjust the distance between the two slide rail assemblies. This facilitates the lifting mechanism in adjusting the height of the mounting plate.

[0022] Optionally, based on the testing platform described above, each of the sliding components includes a first track that can be fixed to the base; and / or

[0023] Each of the sliding components includes a support frame and a second track, the support frame being fixed to the base and the second track being fixed to the support frame.

[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the following embodiments are provided to further illustrate this utility model in detail. The nouns and pronouns referring to "person" in this patent application are not limited to specific genders.

[0055] This utility model provides a testing platform for a trolley-type circuit breaker, used to inspect the assembly dimensions of the trolley-type circuit breaker. A trolley-type circuit breaker (not shown in the figure) generally includes a chassis and a circuit breaker, with the circuit breaker located on the chassis. The circuit breaker typically has three phases, each phase corresponding to a pole, and each pole has an upper moving contact and a lower moving contact. After the trolley-type circuit breaker is pushed into the switchgear cabinet, the upper moving contact needs to contact the upper stationary contact in the switchgear, and the lower moving contact needs to contact the lower stationary contact in the switchgear, so that the trolley-type circuit breaker can subsequently perform the corresponding actions and functions.

[0056] like Figure 1The diagram shown is a structural schematic of the testing platform for the handcart-type circuit breaker according to this utility model from one angle. Figure 2 The image shown is a structural schematic diagram of the testing platform for the handcart-type circuit breaker according to this utility model from another angle. Figure 3 The diagram shown is a partial structural schematic of the testing platform for the handcart-type circuit breaker according to this utility model.

[0057] The testing platform for the handcart-type circuit breaker includes a base 1, a first frame 2, a first mounting plate 3, a first stationary contact group, a second mounting plate 5, a second stationary contact group, and two slide rail assemblies.

[0058] Among them, such as Figures 1 to 3 As shown, the surface of the base 1 can be flat to facilitate the placement of other structures. To facilitate the overall movement of the testing platform, rings 11 fixed to its surface can be provided on the base 1, and these rings are located at the four corners of the base 1. When the testing platform needs to be moved, the crane (not shown in the figure) can be looped around these four rings 11 to lift the testing platform as a whole for movement.

[0059] The first frame 2 is vertically mounted on the base 1. The first frame 2 is mainly used to fix the first mounting plate 3 and the second mounting plate 5, which in turn are used to fix the stationary contact. Therefore, it is necessary to ensure the stability of the first mounting plate 3 and the second mounting plate 5. The first frame 2 can be positioned as follows: Figure 1 and Figure 2 The structure shown, namely the first frame 2, includes a base frame 21 and a mounting frame 22, with the mounting frame 22 fixedly connected to the top of the base frame 21. The base frame 21 includes four support legs. The front of the mounting frame 22 is rectangular, and the two sides are similar to triangles, with fixing plates 221 on both sides. The fixing plates 221 not only facilitate the assembly of the mounting frame 22 but also make the mounting frame 22 more stable. The mounting frame 22 is fixed to the top of the base frame 21.

[0060] The first mounting plate 3 and the second mounting plate 5 are both fixed to the first frame 2. As an example, such as... Figure 1 and Figure 2 As shown, the first mounting plate 3 is located above the second mounting plate 5, and the first mounting plate 3 is parallel to the second mounting plate 5.

[0061] The first stationary contact group includes multiple stationary contacts, and the second stationary contact group also includes multiple stationary contacts. To distinguish between opposing concepts, the multiple stationary contacts included in the first stationary contact group are referred to as "upper stationary contacts," and the multiple stationary contacts included in the second stationary contact group are referred to as "lower stationary contacts." The first stationary contact group can be fixed to the first mounting plate 3, and the position of at least one upper stationary contact 4 on the first mounting plate 3 is adjustable. The second stationary contact group can be fixed to the second mounting plate 5, and the position of at least one lower stationary contact 6 on the second mounting plate 5 is adjustable. Here, "the position of at least one upper stationary contact 4 on the first mounting plate 3 is adjustable" means that, for the multiple upper stationary contacts 4, the position of one or a portion of the upper stationary contacts 4 is adjustable, or the position of all the upper stationary contacts 4 is adjustable. Similarly, "the position of at least one lower stationary contact 6 on the first mounting plate 3 is adjustable" means that, for the multiple lower stationary contacts 6, the position of one or a portion of the lower stationary contacts 6 is adjustable, or the position of all the lower stationary contacts 6 is adjustable. As an example, the first stationary contact group includes three upper stationary contacts 4 arranged in a row, with the middle upper stationary contact 4 fixed and the two side upper stationary contacts 4 adjustable; and / or the second stationary contact group includes three lower stationary contacts 6 arranged in a row, with the middle lower stationary contact 6 fixed and the two side lower stationary contacts 6 adjustable. Thus, for a three-phase trolley circuit breaker, only the two side contacts need to be adjusted, improving the efficiency of stationary contact adjustment.

[0062] There are many ways to adjust the positions of the upper stationary contact 4 and the lower stationary contact 6. For example, a slide rail parallel to the base 1 can be provided on the mounting plate, and the positions of the upper stationary contact 4 and the lower stationary contact 6 on the mounting plate can be adjusted by the slide rail. Alternatively, it can be... Figure 1 and Figure 2 As shown, the first mounting plate 3 and the second mounting plate 5 are provided with several fixing holes 82. The upper stationary contact 4 can be adjusted to position on the first mounting plate 3 through the fixing holes 82, and similarly, the lower stationary contact 6 can be adjusted to position on the second mounting plate 5 through the fixing holes 82. The position of the fixing holes 82 can be adjusted according to actual needs, thus making the testing platform suitable for stationary contacts with different spacings. Using the fixing holes 82 to adjust the position of the upper stationary contact 4 on the first mounting plate 3 and the lower stationary contact 6 on the second mounting plate 5 is highly accurate and relatively simple to implement.

[0063] The base 1 can support two slide rail assemblies. The trolley circuit breaker can slide close to the first and second stationary contact groups via the slide rail assemblies. The distance between the two slide rail assemblies is adjustable. Through these slide rail assemblies, the trolley circuit breaker can be pushed with less effort, thereby allowing the moving contacts on the trolley circuit breaker to contact the stationary contacts.

[0064] During use, adjust the spacing between the stationary contacts to the specified dimensions matching the circuit breaker under test, and adjust the spacing between the two slide rail assemblies to the specified dimensions matching the circuit breaker under test. Push the circuit breaker under test onto the slide rail assembly. If it can move smoothly along the slide rail assembly to the mounting plate and contact each stationary contact, it indicates that the dimensions of the circuit breaker meet the requirements; otherwise, it does not meet the requirements. For example, if it cannot move along the slide rail assembly, it indicates that the chassis assembly of the circuit breaker does not meet the requirements; if it can move smoothly along the slide rail assembly but cannot contact one or more stationary contacts, it indicates that the assembly of the corresponding moving contact or pole does not meet the requirements.

[0065] This invention utilizes an adjustable stationary contact assembly and slide rail assembly to inspect the assembly results of a handcart-type circuit breaker. This method is not only highly efficient but also allows for rapid detection of potential structural faults. Furthermore, the testing platform is compatible with various models of handcart-type circuit breakers, demonstrating strong versatility.

[0066] Optionally, the first frame 2 is provided with several mounting holes 23, through which the first mounting plate 3 and the second mounting plate 5 can be fixed to the first frame 2. More specifically, the first mounting plate 3 and the second mounting plate 5 are provided with several first through holes 83, through which the first positioning member 81 passes through the corresponding mounting holes 23 and the first through holes 83, thereby fixing the first mounting plate 3 and the second mounting plate 5 to the first frame 2. This fixing method is convenient to assemble and has a low cost.

[0067] Optionally, both the first mounting plate 3 and the second mounting plate 5 can be adjusted in position on the first frame 2 via the mounting holes 23. This is because, for different handcart-type circuit breakers, not only may the spacing between contacts differ, but the spacing between the upper and lower contacts may also differ. Figure 1 and Figure 2 As shown, several mounting holes 23 are also provided in the direction perpendicular to the base 1. The spacing between each mounting hole 23 is different. These spacings can be set according to the spacing between the stationary contacts on the various models of handcart circuit breakers to be tested. In this way, by fixing the corresponding mounting holes 23 and the first through hole 83, the spacing between the upper stationary contact 4 and the lower stationary contact 6 can also correspond to the corresponding specifications of the handcart circuit breaker, making the testing platform more universal. Moreover, adjusting the position through the mounting holes 23 is not only highly accurate but also relatively simple to implement.

[0068] Optionally, the testing platform further includes a first lifting mechanism 91 and / or a second lifting mechanism 92. The first lifting mechanism 91 is connected to the first mounting plate 3 and is used to adjust the height of the first mounting plate 3 in the direction perpendicular to the base 1. The second lifting mechanism 92 is connected to the second mounting plate 5 and is used to adjust the height of the second mounting plate 5 in the direction perpendicular to the base 1. Both the first lifting mechanism 91 and the second lifting mechanism 92 can include a rod and a turntable. The rod is connected to the corresponding mounting plate, and the operator can rotate the turntable to move the mounting plate to the corresponding mounting hole 23 before fixing it. In this way, by first adjusting each mounting plate to the corresponding position using the lifting mechanism and then fixing the position through the mounting hole 23, it is not only time-saving and labor-saving, but also highly accurate and relatively simple to implement.

[0069] Optionally, in order to limit the movement direction of the first mounting plate 3 and the second mounting plate 5, a first guide rail 222 can be provided on the first frame 2. The first mounting plate 3 and the second mounting plate 5 can move up and down along the first guide rail 222 in a direction perpendicular to the base 1. This also facilitates the lifting mechanism to adjust the height of the mounting plates. Figure 1 and Figure 2 Two first guide rails 222 are shown. When the first mounting plate 3 and the second mounting plate 5 are moved to the required height, in addition to the positioning element 81 for fixing the position, other fasteners can be used to further fix the first mounting plate 3 and the second mounting plate 5, such as using bolts to fix the mounting plates to the first guide rails 222. Optionally, each upper stationary contact 4 is detachably fixed to the first mounting plate 3, and each lower stationary contact 6 is detachably fixed to the second mounting plate 5. For different handcart-type circuit breakers, the corresponding stationary contact models may be different. For example, the stationary contact of the high current rating is larger, and the stationary contact of the low current rating is smaller. Therefore, both the upper stationary contact 4 and the lower stationary contact 6 can be detachably fixed to the mounting plate, which can realize the replacement of the stationary contact, thereby making the detection platform more versatile. Specifically, detachable fixing can be achieved through fixing holes 82. For ease of installation, both the first mounting plate 3 and the second mounting plate 5 are provided with elongated holes 86, so that each stationary contact can be detachably fixed through the fixing holes 82.

[0070] Optionally, in the first structure, each sliding component includes a first track 71, which can be fixed to the base 1. As an example, such as... Figures 1 to 3As shown, the base 1 has several mounting holes 12. The first rail 71 can be fixed to the base 1 through the mounting holes 12, and its position on the base 1 can be adjusted through the mounting holes 12. Adjusting the position through the mounting holes 12 is convenient and provides good positioning. The edge of the first rail 71 can be provided with several second through holes 84. The positioning element 81 can pass through the mounting holes 12 and the second through holes 84, thus fixing the rail to the base 1. This slide rail assembly can be used for the detection of floor-mounted trolley circuit breakers. For this first structure, since the base 1 has a certain height, an inclined surface 85 can also be placed at the edge of the base 1. Through the inclined surface 85, the trolley circuit breaker can be easily moved onto the first rail 71.

[0071] Optionally, in the second structure, each sliding component includes a support frame 72 and a second rail 73. The support frame 72 can be fixed to the base 1, and the second rail 73 is fixed to the support frame 72. The support frame 72 adjusts the position of the second rail 73 to suit the position of the center-mounted circuit breaker. As an example, the base 1 is provided with several mounting holes 12, and the support frame 72 is provided with a third through hole. The positioning member 81 can pass through the mounting holes 12 and the third through hole, so that the support frame 72 can be fixed to the base 1 through the mounting holes 12, and the position of the support frame 72 on the base 1 can be adjusted through the mounting holes 12. This installation method is more convenient.

[0072] like Figures 1 to 3 As shown, the sliding components of the two structures described above can coexist, or one of them can be used at a time. When both structures are present, if the second structure is required, it can be used directly; if the first structure is required, the support frame 72 and the second track 73 can be moved to either side. This will not affect the testing of the floor-mounted circuit breaker, further improving the versatility of the testing platform.

[0073] Optionally, a second guide rail 13 can be provided on the base 1. The slide rail assembly can slide along the second guide rail 13 to adjust the distance between the two slide rail assemblies. The presence of the second guide rail 13 can make the movement of the slide rail assembly smoother and prevent deviation in the direction of movement. Figures 1 to 3 Two second guide rails 13 are shown. After the slide rail assembly moves to the required distance, in addition to the positioning element 81 to fix the slide rail assembly, other fasteners can be used to fix the position of the slide rail assembly, such as bolts to fix the slide rail assembly to the second guide rail 13. The specific choice can be made according to actual needs.

[0074] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
