[0001] The utility model relates to the technical field of permanent magnet mechanism intelligent pole-mounted vacuum circuit breaker equipment, in particular to a permanent magnet mechanism intelligent pole-mounted vacuum circuit breaker. Background Art

[0002] The permanent magnet mechanism intelligent pole-mounted vacuum circuit breaker is a vacuum circuit breaker that uses a permanent magnet mechanism to achieve intelligent gate disconnection. Since it does not require manual operation, the intelligent gate opening and closing function makes it widely used in high-altitude power systems.

[0003] To protect the existing permanent magnet mechanism intelligent pole-mounted vacuum circuit breakers during transportation, they are mounted on sleepers through pre-set bolt holes at the bottom. When the circuit breaker is subsequently installed, the sleepers are removed and the circuit breaker is mounted on an overhead circuit rack through the bolt holes. During transportation, the bolt holes are prone to constant interaction with the sleepers due to bumps, and repeated disassembly and assembly processes can cause thread wear, affecting the subsequent installation stability of the circuit breaker. Therefore, the present invention proposes a permanent magnet mechanism intelligent pole-mounted vacuum circuit breaker that prevents excessive wear of the bolt holes. Utility Model Content

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1-4 As shown, the present invention proposes a permanent magnetic mechanism intelligent pole-mounted vacuum circuit breaker, which includes a circuit breaker housing 1 and support legs 11 fixedly mounted on both sides of the bottom of the circuit breaker housing 1. The support legs 11 are provided with bolt holes 111 for mounting the circuit breaker housing 1 by bolts.

[0029] In this embodiment, the vacuum circuit breaker includes an anti-strain support mechanism 2 for connecting to the circuit breaker housing 1 and the sleeper 3 respectively so that the support leg 11 and the bolt hole 111 opened thereon are idle. The anti-strain support mechanism 2 includes a base 21 that is clamped to the bottom of the circuit breaker housing 1, an adjustable connecting base 22 that is connected to the bottom side of the base 21 and can be adjusted downward in height to allow the support leg 11 to be suspended in the air, a limiting strip 23 that limits the connection between the adjustable connecting base 22 and the sleeper 3, and a heat dissipation hole 24 that passes through the base 21 and the adjustable connecting base 22. The anti-strain support mechanism 2 can be removed from the circuit breaker when it is installed, or it can be retained thereon. When retained, the heat dissipation hole 24 can prevent it from affecting the heat dissipation effect of the circuit breaker;

[0030] Specifically, a slot 211 for the support leg 11 to be inserted into is provided at both ends of the base 21, and a positioning support plate 112 for positioning the adjustable connecting base 22 is fixedly connected to the inner and outer walls of the support leg 11;

[0031] The bottom inner side of the base 21 defines an inner cavity 212 for vertical movement of the adjustable connector 22. An adjustment screw 223 is threadedly connected to the adjustable connector 22. The top end of the adjustment screw 223 is rotatably connected to the inner wall of the inner cavity 212. The adjustable connector 22 also defines a finger groove 224 for facilitating rotation of the adjustment screw 223. When the adjustment screw 223 is rotated, the threaded engagement between the adjustment screw 223 and the adjustable connector 22 causes the adjustable connector 22 to move up and down.

[0032] A positioning ridge 31 is fixedly connected to the upper surface of the sleeper 3, and a positioning slot 222 is provided at the bottom of the adjustable connecting seat 22 for the positioning ridge 31 to engage. The positioning ridge 31 has a first limiting hole 311, and the limiting strip 23 has a second limiting hole 232 at each end that can align with the first limiting hole 311. After the two are aligned, the limiting shaft 4 can be inserted. The limiting shaft 4 can be a screw shaft or a pin shaft.

[0033] A pair of positioning shafts 231 are fixedly connected to the side of the limiting strip 23 facing the adjustable connecting seat 22. The adjustable connecting seat 22 is provided with a positioning hole 221 for the positioning shaft 231 to be horizontally inserted. The position of the limiting strip 23 on the adjustable connecting seat 22 is limited by the insertion of the two.

[0034] The working principle of this embodiment is as follows: To reduce or avoid vibration damage to the support legs 11 and the bolt holes 111 thereon during transportation, etc., the holder 21 is mounted from one side to the bottom of the circuit breaker housing 1. During installation, the two support legs 11 are positioned in the corresponding slots 211, and the positioning bracket 112 is positioned at the bottom of the holder 21 to position the holder 21. The adjusting screw 223 is then rotated, and the threaded engagement between the adjusting screw 223 and the adjustable connecting seat 22 causes the adjustable connecting seat 22 to move downward until the support legs 11 are suspended in the air. Place the entire device on the sleeper 3 so that 33 is inserted into the corresponding positioning slot 222, and then install the limiting strip 23 to the front of the adjustable connecting seat 22. During installation, the two positioning shafts 231 are respectively inserted into the corresponding positioning holes 221, and then use the limiting shaft 4 to connect and fix the positioning protrusion 31 through the second limiting hole 232 and the first limiting hole 311. The installation between the anti-strain support mechanism 2 and the sleeper 3 is completed. At this time, the support leg 11 remains suspended and does not directly contact the sleeper 3. The vibration generated during transportation is difficult to act on the support leg 11, thereby reducing or avoiding strain caused by vibration.

[0035] In summary, through the design of the anti-strain support mechanism 2, the circuit breaker can be fixedly connected to the sleeper 3 during transportation, etc., so that the support leg 11 and the bolt hole 111 thereon remain idle to reduce strain; through the height-adjustable design of the adjustable connecting seat 22, not only can the anti-strain support mechanism 2 be used to support the circuit breaker and the sleeper 3 when connected and ensure that the support leg 11 is suspended in the air, but the adjustable connecting seat 22 can also be retracted into the inner cavity 212 when the circuit breaker is installed on a high-altitude circuit rack to avoid obstructing the use of the support leg 11.

[0036] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
