Description

Technical Field

[0001] The utility model relates to the technical field of lightning arrester temperature monitoring, in particular to an intelligent lightning arrester temperature monitoring device based on wireless transmission and an intelligent lightning arrester. Background Art

[0002] A lightning arrester is a commonly used protection device in a power supply system. The failure of a lightning arrester is a gradual deterioration process. When the lightning arrester deteriorates, its temperature gradually rises. When the lightning protection module fails, since the temperature of the lightning protection device rises sharply and reaches a certain temperature, usually around 150 °C, the low-temperature solder joints of the lightning protection device begin to melt, and the spring mechanical energy stored inside is released to disconnect or separate the lightning protection device from the protection circuit. When the lightning protection module is separated, usually a micro switch on the base of the lightning protection module is linked and released, changing from a normally open state to a normally closed state or vice versa. The changed state of the micro switch is transmitted to the upper computer through a telemetry interface. In the prior art, it can usually only be detected after the lightning arrester completely fails, which poses a great potential safety hazard. There are also some solutions that can detect the temperature information of the lightning protection module. However, these solutions require using the telemetry interface in the lightning arrester to transmit information, resulting in complex wiring and difficult installation and maintenance. Summary of the Utility Model

[0009] A further technical solution thereof is that both ends of the thin wire segment are fixed on both sides of the guide rail groove. When the low-temperature solder joint melts, the elastic member drives the impact rod to slide along the guide rail groove to break the thin wire segment.

[0026] See Figure 1-2 , an intelligent lightning arrester temperature monitoring device based on wireless transmission is proposed in the embodiments of the present utility model, which is applied to an intelligent lightning arrester. In this intelligent lightning arrester temperature monitoring device based on wireless transmission, temperature information is transmitted wirelessly, without using the telemetry interface in the lightning arrester to transmit temperature information, the wiring is simple, and installation and maintenance are easy. Specifically, the intelligent lightning arrester includes a lightning protection module 12, and the specific structure of the lightning protection module 12 is well known to those skilled in the art and will not be specifically described in this application. The intelligent lightning arrester temperature monitoring device based on wireless transmission includes a detection unit and a monitoring unit 2, and the detailed structure is introduced as follows:

[0027] The monitoring unit 2 includes a short-range wireless transceiver module 26, and the detection unit includes a short-range wireless temperature sensor 121. For example, the short-range wireless transceiver module 26 is an RFID transceiver module, and the short-range wireless temperature sensor 121 is an RFID temperature sensor. RFID is the abbreviation of Radio Frequency Identification, and its Chinese meaning is wireless radio frequency identification, which is a communication technology that can identify specific targets through radio signals and read and write relevant data.

[0028] The short-range wireless temperature sensor 121 is disposed on the lightning protection module 12 for detecting the temperature information of the lightning protection module 12 and sending the temperature information of the lightning protection module 12 to the short-range wireless transceiver module 26 of the monitoring unit 2; the short-range wireless transceiver module 26 is used for receiving the temperature information of the lightning protection module 12. The monitoring unit 2 is used to connect to a monitoring device and / or a gateway device to send the temperature information of the lightning protection module 12 to the monitoring device and / or the gateway device. The monitoring device can be a host computer, and the gateway device can upload the temperature information of the lightning protection module 12 to the cloud. Thus, the user can obtain the temperature information of the lightning protection module 12 in real time and take timely response actions when the temperature of the lightning protection module 12 reaches the set temperature threshold, thereby ensuring safety.

[0029] In the technical solution of the embodiment of the present utility model, the intelligent lightning arrester temperature monitoring device based on wireless transmission includes a detection unit and a monitoring unit 2. The monitoring unit 2 includes a short-range wireless transceiver module 26. The detection unit includes a short-range wireless temperature sensor 121. The short-range wireless temperature sensor 121 is arranged on the lightning protection module 12 and is used to detect the temperature information of the lightning protection module 12 and send the temperature information of the lightning protection module 12 to the short-range wireless transceiver module 26 of the monitoring unit 2. The monitoring unit 2 is used to be connected to a monitoring device and / or a gateway device. Thus, a user can obtain the temperature information of the lightning protection module 12 in real time and take timely response actions when the temperature of the lightning protection module 12 reaches a set temperature threshold, thereby ensuring safety. At the same time, in this intelligent lightning arrester temperature monitoring device based on wireless transmission, the temperature information is wirelessly transmitted through RFID technology, and there is no need to use a telemetry interface in the lightning arrester to transmit the temperature information, so the wiring is simple and the installation and maintenance are easy.

[0030] Further, in some embodiments, such as this embodiment, the short-range wireless temperature sensor 121 includes a sensor body 1213 and an RF antenna 1211. The sensor body 1213 is connected to the RF antenna 1211 through a wire. Specifically, the sensor body 1213 may include a sensor chip and a sensor temperature probe. The sensor temperature probe is connected to the sensor chip. The sensor temperature probe can be arranged on a lightning protection element of the lightning protection module 12 to improve the accuracy of temperature measurement. The lightning protection element can be, for example, a varistor. The sensor chip is connected to the RF antenna 1211 through a wire. The RF antenna 1211 is used to send the temperature information of the lightning protection module 12 to the short-range wireless transceiver module 26.

[0031] Further, the wire includes a thin wire segment 1212. The diameter of the thin wire segment 1212 is relatively thin and will break when impacted. In this embodiment, the diameter of the thin wire segment 1212 is 0.1 - 0.2 mm. For example, the diameter of the thin wire segment 1212 is 0.1 mm, 0.15 mm or 0.2 mm.

[0032] Further, in order to accurately transmit the tripping information of the lightning protection module 12. The monitoring unit 2 further includes a PCB board 124, an impact rod 123, and an elastic member 126. The impact rod 123 is disposed on one side of the thin wire segment 1212. The impact rod 123 is welded to the PCB board 124 through a low-temperature solder joint 125. The elastic member 126 is configured to drive the impact rod 123 to break the thin wire segment 1212 when the low-temperature solder joint 125 melts. The low-temperature solder joint 125 refers to a solder joint obtained by soldering with low-temperature solder. When the low-temperature solder joint 125 melts, it is considered that the lightning protection module 12 has performed a tripping action. In this embodiment, when the low-temperature solder joint 125 melts, the elastic member 126 drives the impact rod 123 to break the thin wire segment 1212. When the thin wire segment 1212 is broken, the RF antenna 1211 cannot form a loop and cannot respond to the query of the short-range wireless transceiver module 26. Accordingly, the monitoring unit 2 determines that the lightning protection module 12 has performed a tripping action and sends the tripping information to the host computer (monitoring device) or the cloud.

[0033] Further, the monitoring unit 2 further includes a guide rail groove 122, and the impact rod 123 is embedded in the guide rail groove 122. Specifically, the guide rail groove 122 plays a good guiding role to ensure that the impact rod 123 can reliably break the thin wire segment 1212 without error.

[0034] Further, both ends of the thin wire segment 1212 are fixed on both sides of the guide rail groove 122. When the low-temperature solder joint 125 melts, the elastic member 126 drives the impact rod 123 to slide along the guide rail groove 122 to break the thin wire segment 1212. Specifically, both ends of the thin wire segment 1212 can be welded and fixed on both sides of the guide rail groove 122. The height of the impact rod 123 is higher than the height of the thin wire segment 1212. When the low-temperature solder joint 125 melts, the elastic member 126 drives the impact rod 123 to slide along the guide rail groove 122 and impact the thin wire segment 1212, causing the thin wire segment 1212 to break.

[0035] Further, the elastic member 126 is compressively disposed in the guide rail groove 122, and both ends of the elastic member 126 are respectively in contact with the guide rail groove 122 and the impact rod 123. When the low-temperature solder joint 125 melts, the elastic energy stored in the elastic member 126 is released, driving the impact rod 123 to slide along the guide rail groove 122 to break the thin wire segment 1212.

[0036] Specifically, the elastic member 126 is a spring. The spring has good elastic recovery ability and high reliability, and can ensure that the impact rod 123 can break the thin wire segment 1212.

[0037] Further, the monitoring unit 2 further includes a main control unit 25 and a communication interface unit. The main control unit 25 is connected to the communication interface unit and the short-range wireless transceiver module 26. The communication interface unit includes an RS485 interface 22, an RJ45 interface 23, and an NB-IOT interface 24. The RS485 interface 22, the RJ45 interface 23, and the NB-IOT interface 24 are all connected to the main control unit 25. The communication interface unit includes various types of communication interfaces, so as to be able to adapt to various types of monitoring devices and / or gateway devices.

[0038] Further, the monitoring unit 2 further includes a power interface 21, and the power interface 21 is used to connect to an external power supply. The external power supply may specifically be commercial power. The power interface 21 is used to access commercial power to supply power to the main control unit 25.

[0039] It can be understood that the short-range wireless temperature sensor 121 is configured with a power supply module, and this power supply module is used to supply power to the short-range wireless temperature sensor 121.

[0040] Working principle

[0041] Under normal circumstances, after the short-range wireless temperature sensor 121 receives the inquiry information from the short-range wireless transceiver module 26, it feeds back the temperature information it measures. After the monitoring unit 2 receives the feedback information, it judges the deterioration degree of the lightning protection module 12 according to the temperature characteristics of the lightning protection module 12, and further transmits the deterioration degree information to the upper computer or the cloud through the RS485 interface 22 or the RJ45 interface 23 or the NB IOT interface. The remote maintenance personnel determine whether to replace the lightning protection module 12 in advance according to the reported deterioration information to avoid accidents.

[0042] When the lightning protection unit trips, the impact rod 123 will move along the guide rail groove 122 and break the thin wire segment 1212 above the guide rail groove 122. After the thin wire segment 1212 is disconnected, the RF antenna 1211 cannot form a closed loop, and the short-range wireless temperature sensor 121 will not be able to respond to the query information of the short-range wireless transceiver module 26. Based on this, the monitoring unit 2 judges that the lightning protection module 12 has tripped and sends the trip information to the upper computer or the cloud.

[0043] The embodiment of the present invention provides an intelligent lightning arrester, and the intelligent lightning arrester includes the intelligent lightning arrester temperature monitoring device based on wireless transmission as provided in any of the above embodiments.

The intelligent lightning arrester 1 includes three main forms. One is the split type, in which the lightning protection module 12 and the base 11 are inseparable.
