AI Technical Summary
The existing combined vacuum circuit breaker mechanism side plates do not provide support and buffer for the circuit breaker main shaft, which may cause the main shaft to shake or vibrate during rotation, resulting in damage to the main shaft and main shaft hole.
A combined vacuum circuit breaker mechanism side plate was designed. By setting a support rod and a ring spring in the groove on the support base, the support rod and the support plate are pressed towards the center of the main shaft hole, providing support and buffering to avoid shaking and vibration.
This effectively avoids damage to the circuit breaker spindle from impacts with the spindle hole, thus extending its service life.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum circuit breaker technology, specifically to a combined vacuum circuit breaker mechanism side plate. Background Technology
[0002] A combined vacuum circuit breaker is a high-voltage switchgear that integrates a vacuum circuit breaker with other high-voltage electrical equipment (such as disconnecting switches, grounding switches, and current transformers) into a single enclosed module. It combines the high breaking capacity of vacuum arc-extinguishing technology with the compactness of modular design, and is widely used in power systems for circuit protection and control.
[0003] In combined vacuum circuit breakers, the mechanism side plate is an important component of the circuit breaker's mechanical structure. It is mainly used to support and fix internal components and ensure the stability and insulation performance of the overall structure.
[0004] The existing combined vacuum circuit breaker mechanism side plate does not have a mechanism to support and buffer the circuit breaker main shaft, which may cause the circuit breaker main shaft to wobble or vibrate when rotating. This can easily cause the circuit breaker main shaft to collide with the main shaft hole on the side plate, resulting in damage to the circuit breaker main shaft and the main shaft hole, thus affecting its service life.
[0005] 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. Utility Model Content
[0006] The present invention provides a combined vacuum circuit breaker mechanism side plate to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A side plate for a combined vacuum circuit breaker mechanism includes a side plate body. A main shaft hole is formed on the surface of the side plate body. A support seat is provided on one side of the side plate body, concentric with the main shaft hole. A plurality of sliding grooves are formed on the surface of the support seat. A support rod is slidably arranged in each of the plurality of sliding grooves. A support plate is provided at the end of the support rod near the center of the main shaft hole. A slot is provided at the end of the support rod away from the support plate. A ring spring is sleeved on the outside of the support seat. The ring spring is inserted into the slot.
[0009] Preferably, the support base is provided with a cover plate on its front side.
[0010] Preferably, a plurality of the grooves are evenly distributed along the center of the support base.
[0011] Preferably, the support plate has an arc-shaped structure. Beneficial effects
[0012] The above-mentioned technical solutions in the side plate of the combined vacuum circuit breaker mechanism provided by this utility model embodiment have at least one of the following technical effects:
[0013] This utility model, through the above-mentioned technical solution, uses the contraction of the annular spring to push the support rod and support plate towards the center of the main shaft hole, which can effectively provide support and buffer for the circuit breaker main shaft, avoid the swaying or vibration during the rotation of the circuit breaker main shaft, and prevent the circuit breaker main shaft and main shaft hole from being damaged by collision, thus providing protective redundancy and improving service life.

[0023] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.
[0024] like Figure 1-4 The diagram shown is a structural schematic of a side plate of a combined vacuum circuit breaker mechanism according to a preferred embodiment of the present invention.
[0025] In this embodiment, a side plate body 1 is included. A main shaft hole 2 is formed on the surface of the side plate body 1 for the circuit breaker main shaft to pass through. A support seat 3 is provided on one side of the side plate body 1, concentric with the main shaft hole 2. Several sliding grooves 4 are formed on the surface of the support seat 3, and support rods 5 are slidably mounted within each of the grooves 4. A support plate 6 is provided at the end of each support rod 5 near the center of the main shaft hole 2, and a slot 7 is provided at the end of each support rod 5 away from the support plate 6. A ring spring 8 is sleeved on the outside of the support seat 3 and is engaged in the slot 7, providing inward pressure to the support rods 5. The contraction of the ring spring 8 causes the support rods 5 and support plates 6 to press towards the center of the main shaft hole 2, effectively providing support and buffering for the circuit breaker main shaft. This prevents wobbling or vibration during the rotation of the circuit breaker main shaft, thus avoiding collision damage between the main shaft and the main shaft hole 2, providing redundancy and ensuring service life.
[0026] In this embodiment, a cover plate 9 is provided on the front side of the support base 3. The cover plate 9 is fixed to the front side of the support base 3 by screws. The cover plate 9 covers the slide groove 4. The support rod 5 can be disassembled by removing the cover plate 9.
[0027] In this embodiment, a plurality of the sliding grooves 4 are evenly distributed along the center of the support base 3, and at least six sliding grooves 4 are provided.
[0028] In this embodiment, the support plate 6 has an arc-shaped structure, which allows it to better fit the surface of the circuit breaker spindle.
[0029] The present invention relates to a combined vacuum circuit breaker mechanism side plate, the installation method, connection method or setting method of which are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.
