[0025] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] refer to Figure 1 As shown, a surge protector with monitoring function includes a socket 1, a plurality of surge protection modules 2 sequentially plugged into the socket 1, and a monitoring box 3 disposed on one side of the socket 1.

[0027] Specifically, refer to Figure 3 and Figure 4 , Figure 5 As shown, the surge protection module 2 includes a housing 21, inside which is provided a varistor 22 and a first electrode connector 23 and a second electrode connector 24 located on both sides of the varistor 22; the first electrode connector 23 and the second electrode connector 24 are electrically connected to the varistor 22, and one end of the first electrode connector 23 extends out of the housing 21 to form a first pin 231; one end of the second electrode connector 24 extends out of the housing 21 to form a second pin 241.

[0028] refer to Figure 5 and Figure 6 As shown, the varistor 22 includes a varistor sheet 221, a first electrode 222 is provided on the surface of the varistor sheet 221, and a second electrode 223 is provided on the bottom surface of the varistor sheet 221; the first electrode 222 is electrically connected to the first electrode connector 23; the second electrode connector 24 is electrically connected to the second electrode 223, and an insulating encapsulation layer 224 is covered at the connection between the first electrode 222 and the second electrode 223 and on the outer surface of the varistor sheet 221.

[0029] By setting the insulating encapsulation layer 224, the varistor 221 and the connection points of the first electrode 222, the second electrode 223 and the varistor 221 can be effectively insulated and protected, and the varistor 221 can be prevented from being damaged by the internal and external environment after long-term use. This achieves a good insulation effect, effectively isolates the varistor 221 from the external environment, and improves the arc resistance performance during use.

[0030] The housing 21 has a support frame 25 inside; the support frame 25 has a mounting plate 26 inside, and the varistor 22 is mounted on the first side of the mounting plate 26; the mounting plate 26 has mounting holes 261 that pass through both sides; the support frame 25 has a mounting groove 251 on one side that communicates with the second electrode 223, the first electrode 222 passes through the mounting hole 261 and is electrically connected to the first electrode connector 23, and the second electrode 223 passes through the mounting groove 251 and is electrically connected to the second electrode connector 24.

[0031] refer to Figure 1 and Figure 2 As shown, the socket 1 is provided with plug holes 101 corresponding to the first plug 231 and the second plug 241 respectively and used for electrical connection with the line. The surge protection module 2 is inserted into the plug holes 101 through the first plug 231 and the second plug 241 respectively.

[0032] A contact rod 211 is provided on the outside of the housing 21, and the contact rod 211 is located between the first pin 231 and the second pin 241. The socket 1 is provided with a contact interface 102 corresponding to the contact rod 211. The socket 1 is provided with a micro switch (not shown in the figure) and a remote signaling mechanism (not shown in the figure). The micro switch is located below the contact interface 102, and when the contact rod 211 is inserted into the contact interface 102, the micro switch is triggered, and the remote signaling mechanism sends an indication signal.

[0033] The monitoring box 3 includes a box body 31. The top of the box body 31 has several ventilation holes 32. Several sets of cooling fans 4 are fixedly installed on the top inner side of the box body 31, with the cooling fans 4 facing the ventilation holes 32. A dust filter (not shown in the figure) is provided inside each ventilation hole 32. A heat-conducting layer 6 is also provided inside the box body 31, and the heat-conducting layer 6 is fixedly installed on the side near the socket 1. In this embodiment, the box body 31 is made of a heat-conducting material.

[0034] The heat-conducting layer 6 works with the housing 31 to conduct the heat generated by the surge protection module 2 and the socket 1 into the housing 31, preventing local overheating of the surge protection module 2 and the socket 1, thereby improving the safety of the protector. The cooling fan 4 of the surge protection module 2 and the socket 1 is installed directly opposite the vent 32. The cooling fan 4 can effectively exhaust the hot air inside the housing through the vent 32, thereby reducing the temperature inside the housing 31. This dissipates the heat generated by the surge protection module 2 and the socket 1, preventing heat accumulation that could cause the surge protection module 2 and the socket 1 to overheat, affecting the service life of the surge protector or causing a safety accident, thus improving the performance stability of the surge protector.

[0035] The dust filter (not shown in the figure) installed inside the vent 32 can effectively prevent dust and other impurities from entering the inside of the box 31, which helps to keep the inside of the box 31 clean.

[0036] The heat sink 5 is symmetrically installed on both sides inside the box 31, and the heat sink 5 is provided with a plurality of heat dissipation holes 51. The heat sink 5 is located on one side of the heat-conducting layer 6.

[0037] The heat sink 5 can disperse the heat transferred from the heat conduction layer 6 into the housing 31 to a larger surface area and dissipate it outside the housing 31, thereby assisting the cooling fan 4 in dissipating heat from the housing 31 and improving the heat dissipation efficiency of the housing 31. The setting of the heat dissipation holes 51 can further promote air convection and enhance heat exchange efficiency.

[0038] The housing 31 also houses a controller 7 and a temperature sensor 8 and a humidity sensor 9 electrically connected to the controller 7. The cooling fan 4 is electrically connected to the controller 7. The probe of the humidity sensor 8 passes through the housing 31 to detect the humidity outside the housing 32. In this embodiment, the temperature sensor 8 is a PT1000 type SWL-T1L-UL7; the humidity sensor 9 is a DS18B20; and the controller 7 is a programmable logic controller, specifically a Siemens S7-200.

[0039] The humidity sensor 9 can monitor the humidity level of the environment around the surge protector in real time through the probe passing through the housing 31. This helps to avoid the surge protector from internal short circuits or corrosion caused by high humidity, which could affect the performance and lifespan of the surge protector.

[0040] The housing 31 has an outlet hole (not shown in the figure). The cooling fan 4 is electrically connected to the temperature sensor 8, and the probe of the temperature sensor 8 passes through the outlet hole and contacts the socket 1 to detect the temperature of the socket 1.

[0041] Temperature sensor 8 directly contacts socket 1 through its lead-out hole, enabling real-time acquisition of surface temperature data for socket 1 and eliminating the lag in temperature detection inside housing 31. By monitoring the temperature, potential problems with the surge protector can be detected and diagnosed in a timely manner. Simultaneously, the efficiency of cooling fan 4 can be adjusted based on the temperature data to dissipate heat promptly and prevent overheating.

[0042] Specifically, the monitoring box can detect and collect temperature and humidity data, which can then be sent to the client for recording and alerts, improving the safety of surge protector use. When the temperature is too high, the controller 6 controls the cooling fan 4 to improve heat dissipation efficiency.

[0043] The housing 31 is equipped with a sound and light alarm 10, which is electrically connected to the controller 7.

[0044] When the temperature sensor 8 and humidity sensor 9 detect abnormal temperature or humidity, the audible and visual alarm 9 will issue an audible and visual alarm signal to remind the inspectors, making it easier for them to obtain the test results and improving the safety of the surge protector.

[0045] By incorporating a monitoring box 3, which houses a temperature sensor 8 and a humidity sensor 9, the surge protector's temperature and external humidity can be monitored. This enables safe monitoring of the surge protector, preventing internal short circuits or corrosion caused by high humidity, which could affect its performance and lifespan. Temperature data also allows for timely detection of abnormal usage and adjustment of the cooling fan 4 for efficient heat dissipation. This proactive approach alerts users to potential surge protector malfunctions or failures, ensuring timely detection of any problems and improving the safety of electrical equipment. Furthermore, the cooling fan 4 and vents 32 effectively conduct heat away from the surge protector, enhancing its safety and extending its lifespan.

[0046] Preferably, the box 31 is provided with a power supply interface (not shown in the figure), which is electrically connected to the controller 7 and is used to monitor the power supply of the box 3.

[0047] Preferably, a power supply battery (not shown in the figure) is also provided inside the housing 31, and the power supply battery is electrically connected to the controller 7.
