Description

Technical Field

[0001] This utility model belongs to the field of circuit breaker technology, and in particular relates to a quick-installation circuit breaker. Background Technology

[0002] In modern power systems, circuit breakers play a crucial role as key protection and control devices. They can quickly disconnect circuits when faults such as overloads and short circuits occur, protecting electrical equipment and personnel. With the continuous development of the power industry, higher requirements are being placed on the performance and ease of use of circuit breakers.

[0003] Some existing circuit breakers are not easy to dissipate heat quickly during use, which may make it difficult to effectively dissipate the heat generated during operation. This can lead to an increase in the temperature of internal components, accelerate component aging, and affect the performance and lifespan of the circuit breaker. At the same time, high temperature can also cause problems such as increased contact resistance and changes in tripping characteristics, making the circuit breaker's opening and closing unreliable, the electrical connection unstable, and increasing the probability of failure. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-installation circuit breaker, which solves the problem of some existing circuit breakers not being able to dissipate heat quickly during use by setting a heat dissipation mechanism.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a quick-installation circuit breaker, including a mounting housing, on which a heat dissipation mechanism and a mounting mechanism are provided.

[0006] The heat dissipation mechanism includes a mounting cavity opened on the front side of the mounting housing. A circuit breaker body is slidably connected to the inner wall of the mounting cavity. A heat dissipation window is fixedly connected to the bottom of the circuit breaker body. A support frame is fixedly connected to the inner wall of the heat dissipation window. A cooling fan is fixedly connected to the support frame. An air outlet is fixedly connected to the top of the circuit breaker body. Both the heat dissipation window and the cooling fan are slidably connected to the mounting cavity.

[0007] Furthermore, a filter plate is fixedly connected to the inner wall of the heat dissipation window, and extension windows are fixedly connected to the top and bottom of the mounting housing.

[0008] Furthermore, the installation mechanism includes positioning blocks that are fixedly connected to the left and right sides of the circuit breaker body, and the left and right sides of the mounting housing are provided with sliding grooves.

[0009] Furthermore, positioning rods are slidably connected to the inner walls of both sliding grooves, positioning grooves are provided on the sides of the two positioning blocks that are far apart from each other, and the ends of the two positioning rods that are close to each other extend into the interior of the corresponding positioning grooves and are slidably connected to the corresponding positioning grooves.

[0010] Furthermore, a connecting plate is fixedly connected to each of the two positioning rods, and a spring is wound around each of the two positioning rods.

[0011] Furthermore, one end of each of the two springs is fixedly connected to the corresponding connecting plate, and the other end of each of the two springs is fixedly connected to the inner wall of the corresponding slide groove.

[0012] Furthermore, each of the two positioning rods has a fixing plate fixedly connected to its opposite end, and each fixing plate has two bolts threadedly connected to the mounting housing.

[0013] This utility model has the following beneficial effects: 1. By setting up a heat dissipation mechanism, when the circuit breaker body generates heat during operation, the cooling fan is activated. The cooling fan rotates and generates airflow, which enters through the heat dissipation window, is filtered by the filter plate, and then blows onto the circuit breaker body, carrying away the heat generated during operation. The heat dissipation mechanism dissipates the heat generated during operation in a timely manner, preventing the temperature of the internal components of the circuit breaker body from rising, which would accelerate the aging of the internal components and affect the performance and lifespan of the circuit breaker body. It also reduces problems such as increased contact resistance and changes in tripping characteristics caused by high temperature, ensuring reliable opening and closing of the circuit breaker body, maintaining stable electrical connections, effectively reducing the probability of faults, reducing the risk of power outages caused by faults, ensuring the continuous and stable operation of the power system, and providing reliable power support for various power-dependent equipment and production activities.

[0014] 2. By setting up an installation mechanism, the circuit breaker body is slid into the installation cavity. After the circuit breaker body is fully slid into the installation cavity, the fixing plate is pressed, causing the fixing plate to move towards the installation housing. When the fixing plate moves, it drives the positioning rod to move, and then the end of the positioning rod away from the fixing plate slides into the positioning groove. The installation mechanism enables the circuit breaker body to be quickly installed and removed, allowing workers to quickly remove it from the installation position without spending a lot of time tightening screws and disconnecting wires, saving manpower and time costs. This greatly speeds up the troubleshooting and repair process, effectively shortens the power outage time, and reduces the inconvenience and losses caused by power outages to residents' lives and industrial production. In addition, the convenient quick installation and removal feature also makes it easy to replace the circuit breaker body in a timely manner when the equipment is upgraded or replaced, improving the adaptability and stability of the power system and ensuring the efficiency and reliability of power supply.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5As shown, this utility model is a quick-installation circuit breaker, including a mounting housing 1. The mounting housing 1 is equipped with a heat dissipation mechanism 2 and a mounting mechanism 3. The heat dissipation mechanism 2 includes a mounting cavity 21 located on the front side of the mounting housing 1. A circuit breaker body 22 is slidably connected to the inner wall of the mounting cavity 21. A heat dissipation window 23 is fixedly connected to the bottom of the circuit breaker body 22. A support frame 24 is fixedly connected to the inner wall of the heat dissipation window 23. A cooling fan 25 is fixedly connected to the support frame 24. An air outlet 26 is fixedly connected to the top of the circuit breaker body 22. Both the heat dissipation window 23 and the cooling fan 25 are slidably connected to the mounting cavity 21. A filter plate 27 is fixedly connected to the inner wall of the heat dissipation window 23. Both the top and bottom of the circuit breaker are fixedly connected to extension windows 28, which dissipate heat from the circuit breaker body 22 through the heat dissipation mechanism 2. This dissipates the heat generated during operation in a timely manner, preventing the temperature of the internal components of the circuit breaker body 22 from rising, which would accelerate the aging of the internal components and affect the performance and lifespan of the circuit breaker body 22. It also reduces problems such as increased contact resistance and changes in tripping characteristics caused by high temperature, ensuring reliable opening and closing of the circuit breaker body 22, maintaining stable electrical connections, effectively reducing the probability of faults, lowering the risk of power outages caused by faults, ensuring the continuous and stable operation of the power system, and providing reliable power support for various power-dependent equipment and production activities.

[0021] The mounting mechanism 3 includes positioning blocks 31 fixedly connected to the left and right sides of the circuit breaker body 22. Slide grooves 32 are provided on both the left and right sides of the mounting housing 1. Positioning rods 33 are slidably connected to the inner walls of both slide grooves 32. Positioning slots 34 are provided on the opposite sides of the two positioning blocks 31. The ends of the two positioning rods 33 extend into the corresponding positioning slots 34 and are slidably connected to them. Connecting plates 35 are fixedly connected to both positioning rods 33. Springs 36 are wound around both positioning rods 33. One end of each spring 36 is fixedly connected to the corresponding connecting plate 35, and the other end is fixedly connected to the inner wall of the corresponding slide groove 32. Both ends of the circuit breaker body 22 are fixedly connected to a fixing plate 37. Each fixing plate 37 is threadedly connected to the mounting housing 1 by two bolts 38. The installation mechanism 3 enables the circuit breaker body 22 to be quickly installed and removed, allowing workers to remove it from its installation position quickly without spending a lot of time tightening screws and disconnecting wires, saving manpower and time costs. This greatly speeds up the troubleshooting and repair process, effectively shortens the power outage time, and reduces the inconvenience and losses caused by power outages to residents' lives and industrial production. Furthermore, the convenient quick installation and removal feature also makes it easy to replace the circuit breaker body 22 in a timely manner when the equipment is upgraded or replaced, improving the adaptability and stability of the power system and ensuring the efficiency and reliability of power supply.

[0022] A specific application of this embodiment is as follows: When the circuit breaker body 22 generates heat during operation, the cooling fan 25 is activated. The cooling fan 25 is fixed to the inner wall of the heat dissipation window 23 by the support frame 24. The cooling fan 25 rotates to generate wind, and air enters from the heat dissipation window 23. It is filtered by the filter plate 27 to prevent dust and other impurities from entering the circuit breaker body 22 and affecting its normal operation. The air entering is blown towards the circuit breaker body 22 by the cooling fan 25, which carries away the heat generated during operation. This causes the hot air to rise and be discharged through the air outlet 26. At the same time, the extension windows 28 at the top and bottom of the housing 1 can promote air circulation, allowing external cold air to be better replenished, forming a continuous air circulation, and continuously carrying away the heat generated by the circuit breaker body 22, thereby achieving effective heat dissipation of the circuit breaker.

[0023] When it is necessary to disassemble the circuit breaker body 22, first loosen bolt 38 and remove it. After bolt 38 is removed, the fixing plate 37 is no longer fixed, and the spring 36 returns to its original position under its own elasticity. This causes the spring 36 to move the connecting plate 35. When the connecting plate 35 moves, it moves the positioning rod 33, thereby causing the positioning rod 33 to disengage from the positioning groove 34. After the positioning rod 33 disengages from the positioning groove 34, pull the circuit breaker body 22 forward to disassemble the circuit breaker body 22. When installing the circuit breaker body 22, slide the circuit breaker body 22 into the mounting cavity 21. When the circuit breaker body 22 is completely slid into the mounting cavity 21... Then, press the fixing plate 37 to move it toward the mounting housing 1. When the fixing plate 37 moves, it drives the positioning rod 33 to move, so that the end of the positioning rod 33 away from the fixing plate 37 slides into the positioning groove 34, thereby limiting and fixing the position of the positioning block 31. Then, the positioning block 31 limits and fixes the position of the circuit breaker body 22. When the positioning rod 33 moves, it drives the connecting plate 35 to move. When the connecting plate 35 moves, it drives the spring 36 to stretch. Finally, the fixing plate 37 is fixed to the mounting housing 1 by the bolt 38, so that the positioning rod 33 can no longer move, and the installation of the circuit breaker body 22 is completed.
