Description

Technical Field

[0001] This utility model relates to the field of vacuum circuit breaker technology, and specifically to a vacuum circuit breaker installation mechanism. Background Technology

[0002] Vacuum circuit breakers are named for their high vacuum nature, which is both the arc-extinguishing medium and the insulating medium between the contacts after arc extinguishing. They have the advantages of small size, light weight, suitability for frequent operation, and no maintenance required for arc extinguishing. They are widely used in power distribution networks and can be used in industrial and mining enterprises, power plants, and substations for the protection and control of electrical equipment. They are particularly suitable for applications requiring oil-free operation, minimal maintenance, and frequent operation. Circuit breakers can be installed in medium-voltage switchgear, double-layer switchgear, and fixed switchgear for the control and protection of high-voltage electrical equipment.

[0003] In the prior art, vacuum circuit breakers are all equipped with mounting plates for installation and fixation. The vacuum circuit breaker and the mounting plate are welded into a whole, and the mounting plate is then fixed to the outside by bolts. When the circuit breaker fails and needs to be replaced, the mounting plate also needs to be replaced, resulting in a waste of resources. Furthermore, the installation position and installation height cannot be adjusted, making it unsuitable for different installation environments. For example, patent application number CN201720372030.4, patent name is a prepaid high-voltage vacuum circuit breaker.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Summary of the Invention

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vacuum circuit breaker installation mechanism includes a vacuum circuit breaker and two installation mechanisms respectively installed on both sides of the vacuum circuit breaker. The installation mechanism includes an adjusting plate and an installation plate. Clamping plates are provided on both sides of the adjusting plate. Through grooves are formed on the surface of each clamping plate, and two fixing screws are provided in each through groove. Connecting blocks are provided on both sides of the bottom of the adjusting plate. Connecting blocks are provided on both sides of the rear of the installation plate. Nuts are provided on the rear side of each connecting block. Adjusting screws are inserted through each connecting block, and the threaded end of the adjusting screw is screwed to the nut. Elastic elements are sleeved on each adjusting screw.

[0008] Preferably, the elastic element is a spring, and both ends of the elastic element abut against connecting block one and connecting block two, respectively.

[0009] Preferably, fixing holes are provided on both sides of the surface of the mounting plate.

[0010] Preferably, a support plate is vertically provided at the bottom of the adjustment plate. Beneficial effects

[0011] The above-mentioned technical solutions of one or more technical solutions in the vacuum circuit breaker installation mechanism provided by this utility model embodiment have at least one of the following technical effects:

[0012] This utility model, through the aforementioned technical solution, allows the position of the mounting plate to be adjusted by turning the adjusting screw. This enables the mounting plate's fixing holes to be adjusted according to different installation locations during vacuum circuit breaker installation, allowing the vacuum circuit breaker to adapt to various installation environments. Furthermore, by changing the position of the adjusting plate on the vacuum circuit breaker, the height of the vacuum circuit breaker can be adjusted, allowing it to adapt to different installation heights. Moreover, when the vacuum circuit breaker is damaged, the mounting mechanism can be removed without replacing it simultaneously, avoiding resource waste. Attached Figure Description

[0020] like Figure 1-2 As shown, it is a structural schematic diagram of a vacuum circuit breaker installation mechanism according to a preferred embodiment of the present invention.

[0021] In this embodiment, a vacuum circuit breaker 1 and two mounting mechanisms 2 respectively installed on both sides of the vacuum circuit breaker 1 are included. Each mounting mechanism 2 includes an adjusting plate 3 and a mounting plate 4. Clamping plates 5 are provided on both sides of the adjusting plate 3, forming a right angle with the adjusting plate 3. The adjusting plate 3 is clamped onto the vacuum circuit breaker 1 by the two clamping plates 5. Each clamping plate 5 has a through groove 6 on its surface, and two fixing screws 7 are provided in each through groove 6. The fixing screws 7 fix the clamping plate 5, and the through grooves 6 allow the position of the adjusting plate 3 to be moved, thereby adjusting the height of the vacuum circuit breaker 1. The circuit breaker 1 can adapt to different installation heights. The bottom sides of the adjusting plate 3 are provided with connecting blocks 1 and 8, and the rear sides of the mounting plate 4 are provided with connecting blocks 2 and 9. The rear side of each connecting block 2 and 9 is provided with a nut 10. Each connecting block 1 and 8 is provided with an adjusting screw 11. The threaded end of the adjusting screw 11 is screwed to the nut 10. Each adjusting screw 11 is provided with an elastic element 12. By turning the adjusting screw 11, the position of the mounting plate 4 can be adjusted. In this way, when the vacuum circuit breaker 1 is installed, the position of the fixing hole of the mounting plate 4 can be adjusted according to different installation positions, so that the vacuum circuit breaker 1 can adapt to different installation environments.

[0022] In this embodiment, the elastic element 12 is a spring. The two ends of the elastic element 12 abut against the connecting block 8 and the connecting block 9 respectively. The elastic element 12 provides power to the mounting plate 4. When the adjusting screw 11 is loosened, the elastic element pushes the mounting plate 4 to move away from the vacuum circuit breaker 1.

[0023] In this embodiment, fixing holes 13 are provided on both sides of the surface of the mounting plate 4, and the mounting plate 4 is fixed by screws through the fixing holes 13.

[0024] In this embodiment, a support plate 14 is vertically provided at the bottom of the adjustment plate 3. The support plate 14 increases the contact area between the bottom of the adjustment plate 3 and the installation area, thereby improving the support stability.

[0025] The installation mechanism for a vacuum circuit breaker of this utility model is a common mechanical method in terms of installation, connection or setting. Any method that can achieve its beneficial effect can be implemented.

[0026] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0027] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions.
