[0028] To further illustrate the present invention, the following description is provided with reference to the accompanying drawings. It should be noted that the embodiments described below are merely some, and not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0029] refer to Figure 8 As shown, a surge protector monitoring method includes the following steps:

[0030] Step S1: Acquire real-time data from the surge protector at preset intervals and record the total time t required to acquire this data. This real-time data includes the surge protector's leakage current, voltage, temperature, and humidity. Acquiring real-time data at preset intervals ensures the timeliness and accuracy of monitoring data, capturing subtle changes in the surge protector's status and providing a solid foundation for subsequent analysis and evaluation. By collecting leakage current, voltage, temperature, and humidity values, multi-dimensional performance monitoring of the surge protector is achieved, providing a comprehensive understanding of its operating status.

[0031] Wherein, step S1 also includes: step S1 also includes: when I≥I1 and / or U≥U1 and / or T≥T max and / or H≤H min and / or H ≥ H max and / or H≤H min , a third warning signal is issued and monitoring of the surge protector is stopped. If any of the leakage current, voltage, temperature, and humidity values exceeds the preset threshold, it indicates that the surge protector has failed. At this time, a prompt is issued to the user and monitoring of the surge protector is stopped.

[0032] Step S2: pre-processing the acquired real-time data, wherein the pre-processing includes filtering, denoising and normalizing the acquired real-time data, which significantly improves the quality and usability of the real-time data.

[0033] Step S3: When t exceeds a preset time threshold, a first warning signal is issued. When t exceeds the preset time threshold, it indicates that the surge protector has failed and no further health status assessment is required. The preset time threshold is the maximum time required to obtain real-time data under normal conditions.

[0034] When t is less than or equal to a preset time threshold, the comprehensive health index of the surge protector is obtained based on the preprocessed leakage current, voltage, temperature, and humidity values. The comprehensive health index can intuitively reflect the usage status of the surge protector, allowing users to obtain the usage status of the surge protector in advance.

[0035] The calculation formula of the comprehensive health index A is: Wherein, ω1, ω2, ω3 and ω4 are all weight indices, and ω1+ω2+ω3+ω4=1; I, U, T, H represent the acquired leakage current value, voltage value, temperature value and humidity value respectively; I1 and U1 represent the threshold value of leakage current value and voltage value respectively; T max and T min They represent the maximum and minimum temperatures allowed by the surge protector’s operating environment; H max and H min They respectively represent the maximum and minimum humidity values allowed by the surge protector in its working environment.

[0036] Step S4: Evaluate the health status of the surge protector according to the obtained comprehensive health index, and issue different second warning signals according to the evaluation results.

[0037] In step S4, the steps for evaluating the health status of the surge protector are as follows:

[0038] Step S41: Obtain the real-time comprehensive health index A of the surge protector.

[0039] Step S42: When the comprehensive health index A is greater than the first preset comprehensive health index, the surge protector is in good working condition. When the comprehensive health index A is between the first and second preset comprehensive health indexes, the surge protector is in medium working condition. When the comprehensive health index A is less than the second preset comprehensive health index, the surge protector is in a failure risk state. The first preset comprehensive health index is greater than the second preset comprehensive health index. Both the good working condition and the medium working condition indicate that the surge protector can be used normally, but the comprehensive health index of the medium working condition is slightly worse. The failure risk state indicates that the surge protector is at risk of failure and requires special attention.

[0040] Step S43: issuing different second warning signals according to the health status of the surge protector.

[0041] Based on the comprehensive health index A, the health status of the surge protector is divided into three states: good, medium, and failure risk. This allows users to accurately grasp the degradation trend of the surge protector and avoid the ambiguity of traditional qualitative judgment that leads to the inability to timely discover the true status of the surge protector. This is conducive to the dynamic quantitative inspection of the surge protector and the stable use of the surge protector.

[0042] In this embodiment, the surge protector monitoring method further includes step S5: evaluating the remaining life L of the surge protector according to the obtained comprehensive health index, and issuing a fourth warning signal when the remaining life L is lower than a preset life threshold.

[0043] The remaining life of the surge protector is evaluated through a comprehensive health index, and a fourth warning signal is issued when the life is lower than the preset life threshold. This effectively realizes closed-loop management from status monitoring to life prediction, thereby being able to identify equipment aging trends in advance, providing a scientific basis for preventive maintenance, and avoiding failure of the surge protector caused by sudden failures.

[0044] The calculation formula for the remaining life L is: Among them L first Indicates the design life of the surge protector; A end Indicates the overall health index of the surge protector when it is time to replace it.

[0045] In this embodiment, the first warning signal, the second warning signal, the third warning signal, and the fourth warning signal can be indicated on the outside of the surge protector by indicator lights of different colors.

[0046] The present invention also provides a surge protector monitoring method, which obtains real-time data such as leakage current, voltage, temperature and humidity of the surge protector at preset time intervals to achieve comprehensive monitoring of the surge protector; then, a comprehensive health index of the surge protector is obtained based on the real-time data to evaluate the health status of the surge protector, which can promptly remind the user to pay attention to the use of the surge protector before the surge protector deteriorates or fails, and judge whether there is a risk of failure or deterioration of the function of the surge protector, thereby ensuring that potential problems of the surge protector are discovered in time and improving the safety of electrical equipment use.

[0047] refer to Figure 1 and Figure 2 As shown, a surge protector with a monitoring function includes an intelligent detection module and an indicator light (not shown in the figure) for indicating the health status of the surge protector. The intelligent monitoring module is used to execute a surge protector monitoring method as described above.

[0048] The surge protector has an automatic detection function, which can detect and reflect the health status of the surge protector in real time, and reflect the different health status of the surge protector in different colors through indicator lights, so as to timely discover potential problems of the surge protector and improve the safety of electrical equipment use.

[0049] The surge protector with monitoring function further includes a housing 1, a varistor 2, a first electrode connector 3, a second electrode connector 4 and a thermal trip mechanism 5. The indicator light is electrically connected to the varistor 2 through the intelligent detection module.

[0050] Specifically, refer to Figure 3 and Figure 4 As shown, a supporting frame 6 is provided inside the housing 1 ; a mounting plate 7 is provided inside the supporting frame 6 , and the varistor 2 is mounted on a first side of the mounting plate 7 .

[0051] Among them, reference Figure 1 As shown, the varistor 2 includes a varistor sheet 201, a first electrode 202 is provided on the surface of the varistor sheet 201, a second electrode 203 is provided on the bottom surface of the varistor sheet 201, and an insulating encapsulation layer 204 is covered on the connection between the first electrode 202 and the second electrode 203 and the outer surface of the varistor sheet 201.

[0052] By providing the insulating encapsulation layer 204, the varistor 201 and the connection locations of the first electrode 202, the second electrode 203 and the varistor 201 can be effectively insulated and protected by the insulating encapsulation layer 204, and the problem of the varistor 201 being damaged by the internal and external environments after long-term use can be avoided, thereby achieving a good insulation effect, effectively isolating the electrical contact between the varistor 201 and the external environment, and improving the arc resistance performance during use.

[0053] refer to Figure 6 、 Figure 7 as well as Figure 3 、 Figure 4 As shown, the first electrode connector 3 includes a first pin 301 and a thermal release 302. The thermal release 302 is welded to the first pin 301 and the first electrode 202, respectively, using a low-melting-point alloy. The second electrode connector 4 is welded to the second electrode 203 at one end and has a second pin 401 at the other end. In this embodiment, the low-melting-point alloy is Field's alloy, and the thermal release has a welded area S of ≥3 mm.

[0054] When an abnormal current or excessive temperature occurs in the circuit, the low-melting-point alloy will melt, causing the connection between the thermal release component 302 and the first pin 30 and the first electrode 202 to be disconnected, thereby quickly cutting off the circuit and preventing equipment damage or safety accidents such as fire, thereby improving the reliability and safety of the surge protector.

[0055] Among them, the mounting plate 7 is provided with mounting holes 8 running through both sides; one side of the supporting frame 8 is provided with a mounting groove 9 connected to the second electrode 202, the first electrode 202 passes through the mounting hole 8 and is welded to the thermal release component 302, and the second electrode 203 passes through the mounting groove 9 and is welded to the second electrode 203 connecting piece.

[0056] refer to Figure 3 and Figure 5 As shown, an observation window 10 is provided on the top of the shell 1, and a fault status indication area 11 is provided on the top of the carrier 6; the fault status indication area 11 is opposite to the observation window 10; the thermal trip mechanism 5 includes a rotating shaft 501 and a rotating member 502 arranged on the second side of the mounting plate 7, and the rotating member 502 is provided with a first end angle A, a second end angle B and a third end angle C, and the first end angle A can be rotatably mounted on the rotating shaft 501, and is connected to an abutment rod 503 near one end of the shell 1, and the second end angle B is located on one side of the thermal trip member 302; the third end angle B is located above the fault status indication area 11, and a normal status indication area 12 is provided on the side of the third end angle B facing the observation window 10.

[0057] An opening 13 is provided at the bottom of the housing 1. When the surge protector is plugged into a socket 14, the abutment rod 503 passes through the opening 13 to trigger the micro switch 141 in the socket, and the rotating member 502 rotates around the rotating shaft 501 in a direction close to the thermal release member 302 so that the second end angle B is in close contact with the thermal release member 302, and the normal state indication area 12 is located directly below the observation window 10, and the normal state indication area 12 is located above the fault state indication area 11.

[0058] When the surge protector is plugged into a socket 14, the micro switch 141 abuts against the abutment rod 503 and applies an upward force to the abutment rod 503. The abutment rod 503 is connected to the first end angle, thereby causing the rotating member 502 to rotate around the rotating shaft 501 in a direction close to the thermal release member 302, that is, rotates in a clockwise direction until it is in close contact with the thermal release member 302. At this time, the varistor 2 is working normally, and the normal status indicator area 12 can be observed through the observation window 10 to indicate that the varistor is in normal use.

[0059] After the thermal release part 302 is desoldered, the rotating part 502 continues to rotate around the rotating shaft 501 in the direction close to the thermal release part 302 and drives the abutment rod 503 to disengage from the micro switch 141, and the third end angle C is away from the observation window 10, so that the fault status indication area 11 is located directly below the observation window 10.

[0060] When the low-melting-point alloy at both ends of the thermal release component 302 melts at high temperature, the connection between the thermal release component 302 and the first electrode 202 and the first pin is disconnected, causing the thermal release component 302 to become desoldered and the varistor to be in a tripped state. At this time, the thermal release component 302 falls, causing the second end corner B to lose its limiting support. Since the position of the rotating shaft is located at the first end corner A, that is, the center of gravity is offset to one side of the first end corner A, under the action of gravity, the second end corner B, which has lost its abutment, rotates around the rotating shaft 501 in a direction close to the thermal release component 302, that is, continues to rotate clockwise, causing the normal state indicator area 12 on the first end corner A to move away from the observation window 10, and thus causing the fault state indicator area 11 to be located directly below the observation window 10. It can be seen through the observation window 10 that the fault state indicator area 11 indicates that the varistor 2 is in a tripped state.

[0061] Among them, a limit plate 15 is provided on the mounting plate 7, and the limit plate 15 is located above the thermal release part 302. After the thermal release part 302 is unsoldered, the rotating part 502 continues to rotate around the rotating shaft in the direction close to the thermal release part 302 until it abuts against the limit plate 15, that is, Figure 5 The state of the rotating member 502 is shown, thereby limiting the excessive rotation of the rotating member 502.

[0062] In this embodiment, the normal status indicator area 12 and the fault status indicator area 11 are marked with different colors. Specifically, the normal status indicator area 12 is marked with green, and the fault status indicator area 11 is marked with red. The coordinated design of the observation window 10 and the fault status indicator area 11 and the normal status indicator area 12 allows users to intuitively judge the device status, allowing users to quickly troubleshoot faults.

Obviously, other modifications and variations may be made based on the contents of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
