Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breaker technology, specifically a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] The integrated primary and secondary pole-mounted circuit breaker is a key integrated and intelligent device in the power distribution network, undertaking functions such as short-circuit protection, overload protection, fault isolation, remote monitoring, and data acquisition. Its core feature is the deep integration of traditional "primary equipment" and "secondary equipment," realizing the miniaturization, intelligence, and integrated operation of the equipment.

[0003] Pole-mounted circuit breakers are exposed to the outdoors for extended periods. Factors such as temperature, vibration, and component wear can cause minor displacements or gaps in the mechanical mechanism. The spring beneath the isolating blade can compensate for these errors through its elasticity. However, over long periods of operation, the spring's elasticity gradually decreases, affecting its compensation effect on the components within the pole-mounted circuit breaker. Therefore, the spring needs to be replaced. Since pole-mounted circuit breakers are typically located at high altitudes, replacing the spring requires disassembling the connecting pole. Connecting the pole to the corresponding components of the circuit breaker requires bolts and positioning holes for proper alignment and fixation. This high-altitude operation is difficult and hinders the efficiency of spring replacement. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: such as Figure 1 - Figure 6 The illustrated primary and secondary integrated pole-mounted circuit breaker includes a mechanism box 1, a bracket 2 fixedly installed on one side of the mechanism box 1, and a rocker arm 3 rotatably installed inside the bracket 2. Rotating arms 4 are fixedly sleeved at both ends of the rocker arm 3. Mounting rods 5 are provided on one side of each of the two rotating arms 4. The ends of the two mounting rods 5 away from their respective rotating arms 4 are slidably connected to the bracket 2. Auxiliary springs 6 are sleeved on the outside of each of the two mounting rods 5. Mounting heads 7 are provided at the ends of the two mounting rods 5 near the rotating arms 4, and the two mounting heads 7 are rotatably connected to the two rotating arms 4 respectively. A support mechanism is provided inside the bracket 2 at the end away from the mechanism box 1, and a connecting mechanism is provided inside the ends of the two mounting rods 5 near the rocker arms 3.

[0018] The support mechanism includes two sliding rods 8 and two U-shaped frames 13. A top plate 10 is fixedly installed on the top of the two sliding rods 8. An H-shaped connecting frame 11 is slidably sleeved on the outside of the two sliding rods 8. A U-shaped frame 12 is fixedly sleeved on the end of the H-shaped connecting frame 11 away from the two sliding rods 8. The bottom of the two U-shaped frames 13 is rotatably connected to two mounting heads 7 respectively. The two ends of the U-shaped frame 12 are located inside the two U-shaped frames 13 respectively. A limit component is provided on the top of the H-shaped connecting frame 11.

[0019] The bottom of the two sliding rods 8 are fixedly mounted on a mounting base plate 9, and the bottom of the mounting base plate 9 is fixedly connected to the bracket 2.

[0020] The limiting assembly includes a pull rod 14, which is movably sleeved in the middle of the H-shaped connecting frame 11. A return spring 15 is sleeved on the outside of the bottom end of the pull rod 14, and a limiting plate 16 is rotatably sleeved on the outside of the top end of the pull rod 14.

[0021] The connecting mechanism includes connecting blocks 17. Two connecting blocks 17 are symmetrically slidably disposed at one end of the mounting rod 5 near the mounting head 7. A push block 18 is fixedly installed at one end of each of the two connecting blocks 17. A return spring 21 is fixedly installed between the side of the two connecting blocks 17 that is close to each other and the inner wall of the mounting rod 5.

[0022] Both mounting heads 7 have circular mounting grooves 19 inside, and the two circular mounting grooves 19 cooperate with the two mounting rods 5 respectively.

[0023] One side of each of the two circular mounting slots 19 is connected to a circular limiting slot 20. The diameter of the two circular limiting slots 20 is larger than the diameter of their respective circular mounting slots 19. The two circular limiting slots 20 cooperate with their respective connecting blocks 17.

[0024] Working principle: When replacing the auxiliary spring 6 on the outside of one of the mounting rods 5, first press the two push blocks 18 inwards simultaneously. The two push blocks 18 move closer to each other and squeeze the corresponding reset spring 21. The two connecting blocks 17 then retract into the mounting rod 5. At this time, the mounting rod 5 can be directly pulled out from one end of the bracket 2, and the auxiliary spring 6 on its outside can be removed. The process of removing the auxiliary spring 6 on the outside of the other mounting rod 5 is the same as above. At this time, the two mounting heads 7 rotate under their own gravity. Then, they pull the H-shaped connecting frame 11 to move upward along the two sliding rods 8. As the H-shaped connecting frame 11 moves upward, it drives the U-shaped frame 12 to move synchronously, thereby driving the two U-shaped frames 13 to rotate to a vertical position. When the H-shaped connecting frame 11 moves to the top, it pulls the pull rod 14 to move upward. The return spring 15 is compressed by force, and then the limiting plate 16 is rotated so that the limiting plate 16 is located at the top of the top plate 10. At this time, the position of the entire H-shaped connecting frame 11 can be fixed. As the two U-shaped frames 13 rotate, they drive their respective corresponding mounting heads 7 to rotate, so that the orientation of the circular mounting grooves 19 in the two mounting heads 7 is the same as the installation direction of the two mounting rods 5, thereby facilitating the subsequent installation of the two mounting rods 5. Subsequently, the two mounting rods 5 are inserted into the bracket 2, and the new auxiliary springs 6 are then fitted onto the outside of the two mounting rods 5. Finally, one end of each of the two mounting rods 5 is inserted into the two circular mounting slots 19. Through the set connection mechanism, the mounting rods 5 can be quickly disassembled and assembled with the mounting head 7, which replaces the existing method of fixing the mounting rods 5 by mutual correspondence between bolts and positioning holes, and is conducive to improving the replacement effect of the auxiliary springs 6.
