The cabinets are stably placed through a parallel connection base. The clamping groove and the convex insertion plate can be used to splice another set of parallel connection bases. The first parallel connection plate and the second parallel connection plate can be freely combined into a frame to fix the outer walls of the cabinets around. The inner surfaces of the first parallel connection plate and the second parallel connection plate can be mutually attached to the outer walls at the bases of multiple gas-insulated switchgear cabinets, so that when increasing or decreasing the number of cabinets, the connection between the cabinets can be made closer, and at the same time, the stability after parallel connection is ensured.

[0005] In order to solve the above technical problems, the utility model solves the problem that the external connection of the parallel connection device for gas-insulated switchgear cabinets is not tight when paralleling multiple cabinets, resulting in poor overall stability.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0034] Please refer to Figure 1 - Figure 6 , a parallel connection device for gas-insulated switchgear cabinets, including a parallel connection mechanism provided on a plurality of gas-insulated switchgear cabinets 1. The parallel connection mechanism includes a parallel connection base 2, a first parallel connection plate 3 and a second parallel connection plate 4. The first parallel connection plate 3 and the second parallel connection plate 4 can be freely combined and are located on the parallel connection base 2 for stability. One end of the parallel connection base 2 is provided with a clamping groove 201, and the other end is connected with a convex insertion plate 202.

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the parallel connection device for gas-insulated switchgear cabinets of this application mainly uses the parallel connection mechanism provided on the gas-insulated switchgear cabinet 1 to perform parallel connection processing between multiple cabinets. Among them, the parallel connection mechanism is mainly composed of a parallel connection base 2, a first parallel connection plate 3 and a second parallel connection plate 4 to perform parallel connection and integration between multiple cabinets. The parallel connection base 2 is used for stably placing the cabinets. The clamping groove 201 is opened on one side of the parallel connection base 2, and the convex insertion plate 202 is installed on the other side of the parallel connection base 2. The two are arranged to cooperate with each other for insertion, so that another group of parallel connection bases 2 can be spliced together later. There are two groups of both the first parallel connection plate 3 and the second parallel connection plate 4. After they are freely combined, they form a frame to fix the outer walls of the cabinets around. The inner surfaces of the first parallel connection plate 3 and the second parallel connection plate 4 can be mutually attached to the outer walls at the bases of a plurality of gas-insulated switchgear cabinets 1, so that when the number of cabinets is increased or decreased, the connection between the cabinets can be made closer, not only relying on the original connection structure for connection. At the same time, the stability after parallel connection is also ensured.

[0036] In some embodiments, the combined cabinet base 2, the first combined cabinet board 3 and the second combined cabinet board 4 can be completely designed according to the number of combined cabinets. Built-in grooves 203 are provided at the front and rear ends of the upper surface of the combined cabinet base 2, so that the first combined cabinet board 3 can be inserted therein to position the first combined cabinet board 3. Among them, a connection structure is arranged inside the built-in groove 203 to assist in installing the first combined cabinet board 3. The connection structure is mainly composed of an installation frame 7 and a bottom insertion plate 702, and two groups are arranged to match the built-in groove 203 and the first combined cabinet board 3. The bottom insertion plate 702 is fixedly installed at the bottom of the first combined cabinet board 3. The installation frame 7 can be slidably inserted into the convex insertion plate 202 and can be clamped into the groove above the installation frame 7. The bottom insertion plate 702 has a certain elasticity. When the bottom insertion plate 702 is clamped into the groove of the installation frame 7, a large frictional force is generated with the inner wall of its groove to ensure the stability of its connection. At the same time, after the set installation frame 7 is inserted into one end of the built-in groove 203, the other end is constructed into a bent state and fits with the outer wall of the combined cabinet base 2 to limit the installation frame 7. At the same time, with this design, the first combined cabinet board 3 being installed can be disassembled at any time, and the above overall structure can also be disassembled by removing the installation frame 7, realizing the flexibility between the structures.

[0037] It should also be noted that the two ends where the first combined cabinet board 3 and the second combined cabinet board 4 are butted are threadedly connected by long fastening bolts 5, so that the first combined cabinet board 3 and the second combined cabinet board 4 can be freely combined together, and at the same time, it is also convenient for the operation during combined cabinet. Among them, the long fastening bolts 5 are set to have a certain length, and the distance between the second combined cabinet board 4 and the first combined cabinet board 3 can be adjusted according to the difference in the combined cabinet length of the cabinet body to improve the applicability.

[0038] This application also provides a pressing block 701. The pressing block 701 is glued to the bottom of the bent end of the installation frame 7. When it is in close contact with the outer wall of the combined cabinet base 2, it hooks on the bottom of the combined cabinet base 2 and is in close contact with the bottom of the combined cabinet base 2 to further ensure the stability of the connection between the installation frame 7 and the combined cabinet base 2.

[0039] A stabilizing layer 401 is also provided in this application. The stabilizing layer 401 is designed with a rubber material and is glued to the inner surface of the second combined cabinet board 4. When the long fastening bolts 5 are tightened to install the second combined cabinet board 4 on the first combined cabinet board 3, the second combined cabinet board 4 exerts a squeezing force on the outer wall of the base of the inflatable cabinet body 1, so that the stabilizing layer 401 can be closely attached to the outer wall of the combined cabinet base 2, thereby increasing the frictional force at its connection and at the same time ensuring the stability of the second combined cabinet board 4 when fixing the cabinet body.

[0040] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6, a through hole 8 is also provided in the present application. A groove is provided in the middle of the upper surface of the cabinet combining base 2, so that a part of the bottom of the inflatable cabinet body 1 can be suspended thereon. A plurality of through holes 8 are evenly formed in the periphery of the groove to improve the heat dissipation of the bottom of the inflatable cabinet body 1. When the cabinet is lifted, the air circulation can be ensured.

[0041] A plurality of universal wheel members 6 are also provided in the present application. They are inserted at the four corners of the bottom of the cabinet combining base 2. The way of inserting and installing the universal wheel members 6 is convenient for subsequent disassembly according to different application scenarios.
