The circuit breaker monitors the current size and automatically interrupts the circuit to prevent circuit overload when the current exceeds the set rated value. The vacuum circuit breaker in the circuit breaker is a switching device used to disconnect or connect the circuit. Compared with traditional air circuit breakers, vacuum circuit breakers have significant advantages in arc extinguishing performance and durability.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0039] In order to solve the above problems, the utility model proposes a circuit breaker device, which aims to provide a circuit breaker device that can realize multi-point detection of a vacuum circuit breaker so as to ensure that its detection value is more objective. Figures 1 to 3The present invention is a schematic structural diagram of an embodiment of a circuit breaker device provided by the present invention.

[0040] Please refer to Figures 1 to 3 The utility model proposes a circuit breaker device 1000, including a base 1, a vacuum circuit breaker 2, a fixed-point temperature monitoring device 3 and a mobile temperature monitoring device 4. The vacuum circuit breaker 2 is arranged on the base 1. The vacuum circuit breaker 2 includes an arc extinguishing tube 21. The arc extinguishing tube 21 has an incoming terminal 22 and an outgoing terminal 23. The fixed-point temperature monitoring device 3 includes three contact temperature sensors 31. The three contact temperature sensors 31 are respectively arranged on the cylinder body, the incoming terminal 22 and the outgoing terminal 23 of the arc extinguishing tube 21. The mobile temperature monitoring device 4 includes an infrared temperature measuring gun 42. The infrared temperature measuring gun 42 is arranged on the base 1 in a liftable manner and can measure the temperature of the end of the arc extinguishing tube 21.

[0041] The three contact temperature sensors 31 are respectively located at three measuring points of the arc extinguishing tube 21, namely, the first measuring point temperature sensor 311 is arranged at the cylinder part of the arc extinguishing tube 21, the second measuring point temperature sensor 312 is arranged at the incoming terminal 22 of the arc extinguishing tube 21, and the third measuring point temperature sensor 313 is arranged at the outgoing terminal 23 of the arc extinguishing tube 21. Since the temperature rise conditions of various points of the vacuum circuit breaker 2 are inconsistent, measuring the temperature change of a single point will not objectively reflect the temperature rise condition of the entire vacuum circuit breaker 2. The three temperature sensors on the arc extinguishing tube 21 can measure the temperatures of the three points respectively, so as to better monitor the working condition of the vacuum circuit breaker 2.

[0042] The technical solution of the utility model proposes a circuit breaker 1000 and a temperature rise detection system, wherein the circuit breaker 1000 includes a base 1, a vacuum circuit breaker 2, a fixed-point temperature monitoring device 3 and a mobile temperature monitoring device 4. The fixed-point temperature monitoring device 3 includes three contact temperature sensors 31, and the three contact temperature sensors 31 are respectively arranged on the cylinder body of the arc extinguishing tube 21 and the incoming terminal 22 and the outgoing terminal 23 of the arc extinguishing tube 21, and are used to measure the temperatures at three positions of the arc extinguishing tube 21. The mobile temperature monitoring device 4 can be raised and lowered on the base 1 and is located on one side of the arc extinguishing tube 21, and can measure the temperature rise of each point on the arc extinguishing tube 21, so that the temperature rise data of the vacuum circuit breaker 2 can be obtained through the fixed-point temperature monitoring device 3 and the mobile temperature monitoring device 4, so as to obtain a more objective detection result.

[0043] In order to realize that the infrared temperature measuring gun 42 can measure the temperature of different positions of the arc extinguishing tube 21 along the axial direction of the arc extinguishing tube 21, the mobile temperature monitoring device 4 includes a telescopic rod 41, the telescopic rod 41 is arranged on the base 1, and the infrared temperature measuring gun 42 is arranged at the end of the telescopic rod 41 away from the base 1. The extension and retraction of the telescopic rod 41 can drive the lifting and lowering of the infrared temperature measuring gun 42, thereby ensuring that the infrared temperature measuring gun 42 can measure multiple measurement positions of the arc extinguishing tube 21. Furthermore, the infrared temperature measuring gun 42 can also rotate around the telescopic rod 41. For details, please refer to Figure 2 and Figure 3 A rotating seat 43 is provided at the end of the telescopic rod 41, and the rotating seat 43 includes a seat body 431 and a driving wheel 433. The seat body 431 is provided at one side of the telescopic rod 41, and an annular strap 432 is provided on the side of the seat body 431 facing the telescopic rod 41. The seat body 431 is sleeved on the telescopic rod 41 through the annular strap 432. The seat body 431 is L-shaped as a whole, and the infrared temperature measuring gun 42 is provided on the seat body 431. A driving wheel 433 is provided on the side of the seat body 431 facing away from the infrared temperature measuring gun 42. The driving wheel 433 is rotatably provided on the side of the seat body 431 facing the telescopic rod 41, and is rotatably abutted against the outer peripheral wall of the telescopic rod 41. Under the rotation of the driving wheel 433, the seat body 431 will rotate around the telescopic axis, so that the infrared temperature measuring gun 42 can cover multiple vacuum circuit breakers 2 and measure different vacuum circuit breakers 2. In order to provide electric energy to the telescopic rod 41 and the driving wheel 433, the short-circuit device also includes a photovoltaic module 6, which is arranged on the ceiling 11 of the device. The photovoltaic module 6 can make a series of driving structures of the device independent of the power grid, and also make the device more environmentally friendly.

[0044] Furthermore, the circuit breaker device 1000 further includes a central processing unit 5. For details, please refer to Figure 1 The central processing unit 5 is connected to the three contact temperature sensors 31 for communication. The central processing unit can calculate the appropriate operating temperature range of the circuit breaker according to the temperature difference fed back by the three contact temperature sensors 31 based on the neural network algorithm, and then control the cooling device (not marked in the figure) to cool down the circuit breaker. If the circuit breaker is disconnected due to high temperature, the alarm bell connected to the vacuum circuit breaker 2 will start to ring.

[0045] The utility model also proposes a temperature rise detection system, which includes a circuit breaker 1000. The specific structure of the circuit breaker 1000 refers to the above embodiment. Since the temperature rise detection system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
