Description

Technical Field

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

[0002] In the power distribution network of a power system, pole-mounted circuit breakers (PBRs) are critical equipment, bearing the important responsibility of protecting lines and equipment from overloads, short circuits, and other faults. Traditional PBR designs typically consist of two main parts: primary equipment and secondary protection and control devices. Primary equipment mainly includes the switch body, such as a vacuum circuit breaker or an SF6 gas-insulated circuit breaker, which directly participates in the opening and closing of the circuit. The secondary protection and control devices are responsible for monitoring electrical parameters, determining fault types, and executing protective actions. They are connected to the primary equipment via cables to achieve information exchange and control. However, this separate design has several shortcomings. First, the physical separation between the primary equipment and the secondary protection and control devices requires long-distance cable connections, which not only increases system complexity and cost but also easily introduces electromagnetic interference and signal attenuation, affecting system stability and reliability. Second, the separate design makes equipment maintenance, upgrades, and replacements cumbersome and time-consuming, reducing operational efficiency. Finally, with the development of smart grids, the requirements for the intelligence and integration of distribution equipment are increasing, and traditional separate PBR designs are no longer sufficient to meet the needs of modern distribution networks.

[0003] To address the aforementioned issues, the integrated primary and secondary pole-mounted circuit breaker has emerged. This integrated pole-mounted circuit breaker is a new type of power distribution equipment that tightly integrates primary switching equipment with secondary protection control units. However, existing integrated pole-mounted circuit breakers have certain drawbacks. For example, Chinese patent CN 221447073 U discloses a deeply integrated intelligent pole-mounted circuit breaker, comprising a circuit breaker with a mounting base symmetrically fixedly connected to its lower end. A restraining frame is slidably mounted on the upper part of the mounting base. A spring bar is provided on the upper part of the mounting base, with one end of the spring bar fixedly connected to the mounting base. The upper end of the spring bar is in movable contact with the restraining frame. A bolt is clamped inside the restraining frame, and the bolt penetrates the mounting base and the restraining frame. The device utilizes the elastic force of the spring clip to act upwards on the restraint frame, keeping the restraint frame on the upper side. The bolt is inserted into the bolt, and the restraint frame clamps the bolt and stabilizes it on the upper side. During installation, the bolt is pressed down and screwed into the target threaded hole, thus facilitating the installation of the circuit breaker. When using this device, if it needs to be fixed to a utility pole, traditional devices can only be used for fixed utility poles of a certain size and cannot be adjusted according to the actual usage scenario. Furthermore, fixing requires twisting many fixing structures, which increases the difficulty of fixing the device and reduces its fixing efficiency. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0023] The primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker body 1 for connecting lines. A support member 2 is fixedly connected to the bottom of the circuit breaker body 1. A fixing member 3 is installed on one side of the support member 2. The fixing member 3 includes a connecting part and a clamping plate 37. An installation cavity that abuts against the utility pole is formed between the connecting part and the clamping plate 37.

[0024] The connecting part includes multiple side rods 32, and a clamping plate 37 is sleeved between the multiple side rods 32. A pull plate 36 is provided on both sides of the clamping plate 37 symmetrically. A spring 310 is installed between the pull plate 36 and the clamping plate 37. A clamping rod 39 is fixedly connected to the side of the pull plate 36 facing the clamping plate 37. One end of the clamping rod 39 extends into the interior of the clamping plate 37 and abuts against the side rods 32.

[0025] With the above technical solution, when personnel need to install the circuit breaker body 1, the support 2 is placed on one side of the utility pole, and the fixing part 3 on one side of the support 2 is pressed tightly against the utility pole. Then, the clamping plate 37 is placed on the other side of the utility pole, so that the side rod 32 passes through the clamping plate 37, and the utility pole is placed between the side rod 32 and the clamping plate 37. The clamping plate 37 is pulled, so that the clamping plate 37 moves along the side rod 32 until the clamping plate 37 touches the utility pole. The spring 310 pulls the pull plate 36, so that the pull plate 36 moves. When the pull plate 36 moves, it will drive the clamping rod 39 to move, so that one end of the clamping rod 39 is inserted into the inside of the clamping plate 37 until the clamping rod 39 touches the side rod 32, thereby fixing the clamping plate 37 and fixing the support 2 to the utility pole. The circuit breaker body 1 is supported by the support 2. Then, the cables that need to be connected are connected to the circuit breaker body 1, thereby controlling the on / off of the line.

[0026] Specifically, in one embodiment, regarding the aforementioned support member 2:

[0027] like Figures 1-5 As shown, the support member 2 includes a base frame 21, and a reinforcing frame 22 is fixedly connected to the bottom of the base frame 21.

[0028] In this embodiment, after the device is fixed to the utility pole, the base frame 21 is supported by the fixing member 3, and the strength of the base frame 21 is increased by the reinforcing frame 22.

[0029] Furthermore, regarding the aforementioned connecting portion in this utility model:

[0030] like Figures 1-5 As shown, the connecting part includes two side plates 31, which are fixedly connected to the two symmetrical sides of the base frame 21 respectively, and the side rod 32 is fixedly connected to the side plate 31 adjacent to the side of the base frame 21.

[0031] In this embodiment, the side plate 31 is supported by the base frame 21, and the side rod 32 is supported by the side plate 31. When the side plate 31 is placed on one side of the utility pole, it is engaged with the side rod 32 by the clamping plate 37. The spring 310 pulls the pull plate 36, which causes the pull plate 36 to move the clamping rod 39, so that the clamping rod 39 moves into the inside of the clamping plate 37 and abuts against the side rod 32, thereby fixing the device on the utility pole.

[0032] To increase the adjustment range of the device, such as Figures 1-5As shown, an extension rod 33 is provided at the end of the side rod 32 away from the side plate 31. A connecting rod 311 is fixedly connected to one end of the extension rod 33 near the side rod 32, and a second connecting hole 34 matching the connecting rod 311 is opened at the other end. The free end of the side rod 32 is recessed to form a first connecting hole 38 matching the connecting rod 311.

[0033] In this embodiment, before the personnel need to fix the device, the extension rod 33 is screwed to the second connecting hole 34 on another extension rod 33 through the connecting rod 311. According to the above steps, the personnel connect the required number of extension rods 33 to adjust the length of the extension rod 33. After the length of the extension rod 33 is adjusted, the extended rod 33 with the adjusted length is screwed to the first connecting hole 38 on the side rod 32 through the connecting rod 311 to increase the adjustment range of the clamping plate 37.

[0034] When adjusting the device, to ensure a tighter fit between the locking lever 39 and the extension lever 33 and side lever 32, such as... Figures 3-5 As shown, both the extension rod 33 and the side rod 32 have an indentation on one side to form a side groove 35 that matches the locking rod 39.

[0035] In this embodiment, when the locking rod 39 abuts against the extension rod 33 and the side rod 32, the side groove 35 engages to make the locking plate 37 more secure after it is fixed.

[0036] To ensure a more secure fit when the device contacts the utility pole, such as Figures 1-5 As shown, arc-shaped plates 312 are fixedly connected to the opposite sides of the card plate 37 and the base frame 21, and the opposite sides of the two arc-shaped plates 312 are concave to form arc-shaped grooves.

[0037] In this embodiment, after the device is fixed, the arc plate 312 abuts against the utility pole, making the device more secure.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
