Description

Technical Field

[0001] This utility model relates to the field of circuit breaker housing technology, and in particular to an insulating housing structure for a vacuum circuit breaker. Background Technology

[0002] Pole-mounted vacuum circuit breakers play a crucial role in power distribution networks, primarily used for the segmented switching, control, and protection of distribution lines. They are named for their superior arc-extinguishing performance, capable of reliably interrupting and making short-circuit currents. Both the arc-extinguishing medium and the insulating medium in the contact gap after arc extinguishing are high vacuum. This unique design gives them numerous advantages: compact size, lightweight, suitability for frequent operation, and maintenance-free arc-extinguishing components, leading to their widespread application in power distribution networks.

[0003] However, in existing technologies, the housing of vacuum circuit breakers mostly adopts a single-layer protective structure. Under the long-term exposure to complex outdoor environments, the gaps in the housing are prone to accelerated aging due to wind and sun exposure, leading to water ingress. More problematic is that water ingress is often difficult to detect in a timely manner, undoubtedly posing a potential hazard to the safe operation of the equipment. Therefore, an insulating housing structure for vacuum circuit breakers is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an insulating shell structure for a vacuum circuit breaker.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an insulating shell structure for a vacuum circuit breaker, comprising a circuit breaker body and a shell, wherein a sandwich groove is formed on the shell, and a long box is inserted and fixedly connected in the sandwich groove, wherein a plurality of heat sinks are fixedly connected in the long box, and a receiving cavity is formed in the long box; further comprising a processing component, wherein the processing component comprises a pair of first bends, the pair of first bends being located at opposite ends of the long box, for communicating the sandwich groove with the outside for heat dissipation and for drainage, and the processing component being connected to the first bends.

[0006] This utility model provides an insulating housing structure for a vacuum circuit breaker: it includes a circuit breaker body and a housing, the housing has a sandwich groove, a long box is inserted and fixed in the sandwich groove, a plurality of heat sinks are fixedly connected in the long box, and a receiving cavity is formed in the long box; it also includes a processing component, the processing component includes a pair of first bends, the pair of first bends are respectively located at opposite ends of the long box, for communicating the sandwich groove with the outside for heat dissipation, and for drainage, the processing component is connected to the first bends.

[0007] As a further description of the above technical solution: the processing component also includes an observation bottle located below the first bend. The top of the observation bottle is threadedly connected to a fixing plate, and the top of the fixing plate is fixedly connected to a first fixing pipe. A fan blade located inside the first bend is rotatably connected to the first fixing pipe. The first bend is also fixedly connected to a second fixing pipe. One end of the second fixing pipe is fixedly connected to the interlayer groove, and the other end of the second fixing pipe is inserted into the first fixing pipe. By setting up the observation bottle, the first fixing pipe, and the second fixing pipe, when water seeps into the shell, the water will first enter the receiving cavity and then be transported to the first fixing pipe through the second fixing pipes on both sides. The water flows into the observation bottle, which makes it convenient for maintenance personnel to understand the leakage situation in a timely manner.

[0008] As a further description of the above technical solution: Multiple heat-conducting rods are fixedly connected to the bottom of the long box body. These rods are inserted into the shell. By setting multiple heat-conducting rods at the bottom of the long box body, and using existing heat-conducting materials, it is beneficial to transfer heat from the shell to the long box body. Simultaneously, the multiple heat sinks inside the long box body facilitate heat dissipation. Furthermore, since the long box body is connected to the outside world through the first bend pipe, when wind blows, the airflow through the two first bend pipes accelerates the heat dissipation efficiency of the heat sinks. By setting fan blades, when wind blows, the airflow comes into contact with the fan blades, accelerating the airflow and further improving heat dissipation efficiency.

[0010] As a further description of the above technical solution: the long box body is inclined at both ends from the center, forming a downward slope structure.

[0012] This utility model has the following beneficial effects:

[0013] 1. Compared with the prior art, the insulating shell structure of this vacuum circuit breaker, by setting an observation bottle, a first fixed tube and a second fixed tube, allows water to seep into the housing first when there is water seepage, and then be transported to the first fixed tube through the second fixed tube on both sides. The water then flows into the observation bottle, making it easy for maintenance personnel to understand the leakage situation in a timely manner.

[0014] 2. Compared with the prior art, the insulating shell structure of this vacuum circuit breaker, by setting multiple heat-conducting rods at the bottom of the long box, using existing heat-conducting materials, facilitates the transfer of heat from the shell to the long box. Simultaneously, the multiple heat sinks inside the long box facilitate heat dissipation. Furthermore, since the long box is connected to the outside through the first bend pipe, when wind blows, the airflow through the two first bend pipes accelerates the heat dissipation efficiency of the heat sinks. By setting fan blades, when wind blows, the contact between the wind and the fan blades accelerates the airflow, thereby further improving the heat dissipation efficiency.

[0024] 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.

[0025] Reference Figures 1-7 The present invention provides an insulating housing structure for a vacuum circuit breaker, comprising a circuit breaker body 1 and a housing, wherein a sandwich groove 2 is provided on the housing, and a long box 3 is inserted and fixedly connected in the sandwich groove 2, wherein a plurality of heat sinks 4 are fixedly connected in the long box 3, and a receiving cavity 5 is formed in the long box 3; and further comprising a processing component, wherein the processing component comprises a pair of first bends 6, the pair of first bends 6 being located at opposite ends of the long box 3, for communicating the sandwich groove 2 with the outside for heat dissipation, and for drainage, and the processing component is connected to the first bends 6.

[0026] The processing assembly also includes an observation bottle 8 located below the first bend 6. A fixing plate 7 is threaded to the top of the observation bottle 8, and a first fixing pipe 9 is fixedly connected to the top of the fixing plate 7. A fan blade 10 located inside the first bend 6 is rotatably connected to the first fixing pipe 9. The first bend 6 is also fixedly connected to a second fixing pipe 11. One end of the second fixing pipe 11 is fixedly connected to the interlayer groove 2, and the other end of the second fixing pipe 11 is inserted into the first fixing pipe 9. By setting up the observation bottle 8, the first fixing pipe 9, and the second fixing pipe 11, when water seeps into the shell, the water will first enter the receiving cavity 5 and then be transported to the first fixing pipe 9 through the second fixing pipes 11 on both sides. The water flows into the observation bottle 8, which makes it easy for maintenance personnel to understand the leakage situation in a timely manner.

[0027] Multiple heat-conducting rods 12 are fixedly connected to the bottom of the long box 3. The multiple heat-conducting rods 12 are inserted into the shell. By setting multiple heat-conducting rods 12 at the bottom of the long box 3, and the heat-conducting rods 12 are made of existing heat-conducting materials, it is beneficial to transfer heat from the shell to the long box 3. At the same time, the multiple heat sinks 4 inside the long box 3 are beneficial for heat dissipation. In addition, since the long box 3 is connected to the outside through the first bend pipe 6, when the wind blows, the airflow flows through the two first bend pipes 6, which accelerates the heat dissipation efficiency of the heat sink 4. By setting fan blades 10, when the wind blows, the wind comes into contact with the fan blades 10, which accelerates the airflow, thereby further improving the heat dissipation efficiency.

[0028] The first bend 6 and the observation bottle 8 do not contact each other. The side wall of the fixing plate 7 is inclined. By setting the side wall of the fixing plate 7 to be inclined, rainwater dripping onto the fixing plate 7 can slide off during rainy weather, thus avoiding water accumulation.

[0029] The long box 3 is inclined from the center to both ends, forming a downward slope structure. By setting the receiving cavity 5 inside the long box 3 to be a downward slope structure that is inclined from the middle to both ends, when water enters the long box 3, it is beneficial to guide the accumulated water to the direction of the first bend pipe 6 on both sides.

[0030] A pair of clips 13 are fixedly connected to both ends of the fixed plate 7. The pair of clips 13 are arranged opposite each other and are made of elastic material. By setting a pair of clips 13, the clips 13 are attached to the first bent tube 6, and the first fixed tube 9 and the second fixed tube 11 are inserted into each other, thereby facilitating the assembly and disassembly of this structure.

[0031] Working principle: When water seeps into the shell, the water will first enter the receiving cavity 5 and then be transported to the first fixed pipe 9 through the second fixed pipe 11 on both sides. The water will then flow into the observation bottle 8, which will allow maintenance personnel to understand the leakage situation in a timely manner.

[0032] Since the long box 3 is connected to the outside world through the first bend 6, when the wind blows, the airflow flows through the two first bends 6, which accelerates the heat dissipation efficiency of the heat sink 4; by setting the fan blades 10, when the wind blows, the wind comes into contact with the fan blades 10, which accelerates the airflow, thereby further improving the heat dissipation efficiency.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
