The outlet switch module 200 is arranged in the arc extinguishing chamber 100A. Specifically, the outlet switch module 200 includes an arc contact and a main contact. At least one of the arc contact and the main contact can be movably arranged so that the arc contact and the main contact can be connected or disconnected. Specifically, the outlet switch arc extinguishing chamber online monitoring module includes a temperature measuring mechanism 300 and a monitoring mechanism 400. The temperature measuring mechanism 300 is installed on the housing 100 through the mounting through hole 110A, and the outlet switch module 200 is located within the detection range of the temperature measuring mechanism 300.

[0034] The generator outlet switch device described in the embodiment of the present application can avoid the contact of the outlet switch module 200 from being closed or disconnected by limiting the arc space position and accelerating the arc extinguishing to prevent the arc from continuing to burn, thereby ensuring the safety of the device.

[0035] The generator outlet switch device described in the embodiment of the present application detects and processes the temperature of the outlet switch module 200 by setting a temperature measuring mechanism 300 and a monitoring mechanism 400, so as to promptly discover the temperature rise caused by poor contact of the outlet switch module 200, avoid accidents such as fire or explosion caused by long-term accumulation of heat, and has the advantages of improving safety and improving the intelligence of the equipment.

[0036] Combination Figure 3 As shown, Figure 3The schematic diagram of the structure of the temperature measuring mechanism 300 of the generator outlet switch device in an embodiment of the present application is shown. In some embodiments, the temperature measuring mechanism 300 includes a thermal imaging sensor 310, an environmental detection sensor 320, a housing 330 and a fixing component 340. The thermal imaging sensor 310 and the environmental detection sensor 320 are installed in the housing 330. The housing 330 is provided with a detection through hole. The thermal imaging sensor 310 and the environmental detection sensor 320 detect the outlet switch module 200 in the arc extinguishing chamber 100A through the detection through hole. The fixing component 340 is installed in the installation through hole 110A, and the housing 330 is installed in the fixing component 340. By encapsulating the thermal imaging sensor 310 and the environmental detection sensor 320 in the housing 330, and fixing the housing 330 in the installation through hole 110A using the fixing component 340, the thermal imaging sensor 310 and the environmental detection sensor 320 detect the outlet switch module 200. The thermal imaging sensor 310 can obtain the temperature distribution image of the object being measured, and cooperate with the environmental detection sensor 320 to detect the internal stability. The results of the two can also be compared with each other to more accurately determine the temperature of the outlet switch module 200. The thermal imaging sensor 310 and the environmental detection sensor 320 detect the highest temperature point of the outlet switch module 200 and the internal temperature of the generator outlet switch device, so that measures can be taken in advance when the temperature is abnormal to avoid further serious accidents such as fire or explosion, thereby improving the reliability of the operation of the generator outlet switch device and enhancing the safety and intelligence of the generator outlet switch device.

[0037] In an optional embodiment, if Figure 3 As shown, the thermal imaging sensor 310 includes an infrared imaging sensor 311 and a visible light imaging sensor 312. The infrared imaging sensor 311 and the visible light imaging sensor 312 are arranged toward the exit switch module 200, and the infrared imaging sensor 311 and the visible light imaging sensor 312 are both electrically connected to the monitoring mechanism 400. By arranging the infrared imaging sensor 311 to obtain the heat distribution diagram of the exit switch module 200, and then the visible light imaging sensor 312 to obtain the image of the exit switch module 200, the heat map and the image are combined for analysis, and the temperature of the exit switch module 200 can be accurately determined. If a fire or explosion occurs, the internal situation can be observed in real time through the visible light imaging sensor, and an accurate judgment can be made in time to improve the safety of the equipment.

[0038] Furthermore, if Figure 3As shown, the thermal imaging sensor 310 also includes a fill light 313, which is arranged toward the outlet switch module 200, and is used to provide a light source for the visible light imaging sensor 312. Since the generator outlet switch device is closed and has no light source inside, the visible light imaging sensor 312 cannot form an image in the dark. By adding the fill light 313, the visible light imaging sensor 312 can be assisted to obtain a clear image, thereby ensuring the reliability of the operation of the temperature measuring mechanism 300.

[0039] In an optional embodiment, if Figure 4 As shown, the fixing assembly 340 includes a transition flange 341 and a fixing sleeve 342. The transition flange 341 is arranged in the mounting through hole 110A, and the transition flange 341 is connected to the housing 100 through a fastener 343. The transition flange 341 is provided with a mounting cavity 341A, the housing 330 can be movably mounted in the mounting cavity 341A, and the fixing sleeve 342 can be movably connected to the transition flange 341. The fixing assembly 340 is used to fix the temperature measuring mechanism 300. Since the housing 100 is provided with a mounting through hole 110A, the transition flange 341 is installed in the mounting through hole 110A through the fastener 343, and then the housing 330 of the temperature measuring mechanism 300 can be installed in the mounting cavity 341A of the transition flange 341, and the fixing sleeve 342 can clamp the transition flange 341 to limit the housing 330, so that the temperature measuring mechanism 300 can be fixed on the housing 100 and the sealing of the housing 100 is ensured. When the sensor needs to be disassembled, the fixing sleeve 342 can be disassembled to conveniently remove the housing 330 and the sensor in the housing 330 , which has the advantages of good sealing and convenient disassembly and assembly.

[0040] Furthermore, if Figure 4 As shown, the overall outer diameter of the transition flange 341 is designed to be larger than the mounting through hole 110A, so that even if the fastener 343 becomes loose, the transition flange 341 will not fall into the arc extinguishing chamber 100A.

[0041] In an optional embodiment, if Figure 4 As shown, the fixing sleeve 342 is connected to the transition flange 341 through a threaded pair. By connecting the fixing sleeve 342 and the transition flange 341 through a threaded pair, after the housing 330 is placed in the installation cavity 341A, the fixing sleeve 342 is screwed to the installation cavity 341A of the transition flange 341 through a thread, so that the housing 330 and the sensor are firmly installed in the installation cavity 341A. In other embodiments, the fixing sleeve 342 can also be a shrink buckle. After the housing 330 is placed in the installation cavity 341A, the fixing sleeve 342 is detachably mounted on the transition flange 341. The shrink buckle can press the installation cavity 341A to fix the housing 330. The housing 330 can be removed by loosening the fixing sleeve 342, so that the temperature measuring mechanism 300 can be easily inspected and repaired.

[0042] In an optional embodiment, if Figure 4 As shown, the fixing assembly 340 further includes a first sealing ring 344 and a second sealing ring 345. The inner wall of the installation cavity 341A is provided with a first sealing groove 341B, the first sealing ring 344 is arranged in the first sealing groove 341B, the end surface of the transition flange 341 connected to the housing 100 is provided with a second sealing groove 341C, and the second sealing ring 345 is arranged in the second sealing groove 341C. By providing the first sealing groove 341B and installing the first sealing ring 344, the gap between the transition flange 341 and the housing 100 is filled by the first sealing ring 344, and by providing the second sealing groove 341C and installing the second sealing ring 345, the gap between the transition flange 341 and the housing 100 is filled by the second sealing ring 345, thereby improving the sealing between the entire temperature measuring mechanism 300 and the housing 100, and ensuring the stability of the equipment operation.

[0043] In an optional embodiment, if Figure 5 As shown, the monitoring mechanism 400 includes a server 410, a display 420, a data acquisition unit 430, a switch 440, a power module 450 and a screen cabinet 460. The server 410, the display 420, the data acquisition unit 430, the switch 440, and the power module 450 are arranged in the screen cabinet 460. The display 420 is electrically connected to the server 410, the data acquisition unit 430 is installed on the server 410, the data acquisition unit 430 is electrically connected to the temperature measuring mechanism 300 through the switch 440, the power module 450 is electrically connected to the temperature measuring mechanism 300, and the power module 450 is used to provide power to the temperature measuring mechanism 300. The temperature measurement mechanism 300 collects temperature data and image data and transmits them to the data acquisition unit 430 through the switch 440. The data acquisition unit 430 processes the received temperature data and image data using mathematical morphology to eliminate the connection parts between the phases, highlight the main features of the outlet switch module 200, and determine the overall area of ​​the equipment according to the area size. The server 410 marks and analyzes the identified area and displays the results on the display 420. When an abnormal situation occurs, the server 410 can output it to the alarm center. At the same time, the server 410 records the relevant information, which is convenient for statistical analysis of the temperature changes in the entire monitoring period, and has the advantage of high intelligence.

[0044] In an optional embodiment, if Figure 1 and Figure 2As shown, the housing 100 includes an inspection cover 110, and an inspection port is provided at the top of the housing 100. The inspection cover 110 is covered on the inspection port, and the inspection cover 110 is movably connected to the housing 100, and the installation through hole 110A is provided on the inspection cover 110. Because the heat in the housing 100 will rise, the best effect is achieved by measuring the temperature downward from the top of the arc extinguishing chamber 100A. Therefore, it is better to install the temperature measuring mechanism 300 on the top of the housing 100, and the top of the general housing 100 is provided with an inspection port and covered with an inspection cover 110, so by setting the installation through hole 110A on the inspection cover 110, the temperature of the outlet switch module 200 can be measured from top to bottom, thereby improving the accuracy of the detection. Moreover, if the temperature measuring mechanism 300 is installed later, it can be set on the detachable inspection cover 110 to improve the convenience of installation.

[0045] The outlet switch arc extinguishing chamber online monitoring module and generator outlet switch device described in the embodiments of the present application have the following beneficial effects:

[0046] 1. By setting up a temperature measuring mechanism 300 and a monitoring mechanism 400 to detect and process the temperature of the outlet switch module 200, the temperature rise caused by poor contact of the outlet switch module 200 can be discovered in time, avoiding accidents such as fire or explosion caused by long-term accumulation of heat, which has the advantages of improving safety and improving the intelligence of the equipment.

[0047] 2. The thermal imaging sensor 310 is used in conjunction with the environmental detection sensor 320 for detection. The results of the two can also be compared with each other to more accurately determine the temperature of the outlet switch module 200, so that measures can be taken in advance when the temperature is abnormal to avoid further serious accidents such as fire or explosion, thereby improving the reliability of the operation of the generator outlet switch equipment and enhancing the safety and intelligence of the generator outlet switch equipment.
