Referring to fig. 1 and 2, the present invention provides a high voltage cable temperature detecting device 100, which includes a temperature detecting module 10 and a monitoring host 20. The temperature detection module 10 includes a point type temperature detector 11, a line type temperature detector 12 and a surface type temperature detector 13, wherein the point type temperature detector 11 is arranged on a high voltage cable 200 and is used for detecting the temperature of a position point where the point type temperature detector 11 is positioned to obtain first temperature data, the line type temperature detector 12 is arranged on the high voltage cable 200 along the extending direction of the high voltage cable 200 and is used for detecting the line temperature of a section of the high voltage cable 200 where the line type temperature detector 12 is positioned to obtain second temperature data; the surface temperature detector 13 is disposed corresponding to at least a partial area of the high voltage cable 200, and is configured to detect and acquire a surface temperature of the at least a partial area of the high voltage cable 200 to obtain third temperature data; the monitoring host 20 is connected to the temperature detection module 10, and the monitoring host 20 is configured to identify a temperature anomaly location of the high voltage cable 200 according to the first temperature data, the second temperature data, and the third temperature data. It should be understood that, referring to fig. 2, the high voltage cable temperature detecting apparatus 100 of the present embodiment may simultaneously obtain the first temperature data of one or more detection points on the high voltage cable 200, the second temperature data of one or more sections of the high voltage cable 200, and the third temperature data of one or more areas, and it should be noted that the detection ranges of the point type temperature detector 11, the line type temperature detector 12, and the surface type temperature detector 13 may be independent of each other or at least partially overlap. The monitoring host 20 can monitor and calculate the three temperature data at the same time, so that the temperature of the whole high-voltage cable 200 can be detected more accurately, false alarm of abnormal temperature condition is reduced, the pressure of manual inspection is relieved, and the maintenance cost is reduced.
According to the high-voltage cable temperature detection device 100 provided by the embodiment of the application, the first temperature data of the position point of the point type temperature detector 11, the second temperature data of the high-voltage cable 200 section of the line type temperature detector 12 and the third temperature data of at least partial area of the high-voltage cable 200 are obtained to identify the temperature abnormal position of the high-voltage cable 200, so that multi-dimensional three-dimensional monitoring of the point, line and surface of the cable is realized, the temperature monitoring is more accurate, the judgment of the abnormal position is more accurate, and the accuracy of the temperature detection of the high-voltage cable 200 is improved.
Specifically, the spot temperature detector 11 is provided at the periphery of the high voltage cable 200. Referring to fig. 3, in this embodiment, the point temperature detector 11 may be a contact temperature sensor, and may be directly fixed on the periphery of the insulating layer of the high voltage cable 200, which needs to perform temperature detection, by fastening, pasting, etc., and the point temperature detector 11 may upload the detected first temperature data to the monitoring host 20 by means of wireless communication. The point type temperature detector 11 is simple and convenient to install and construct, the point type temperature detector 11 is arranged on the periphery of the high-voltage cable 200, so that the point type temperature detector 11 does not influence the operation of the high-voltage cable 200 in the detection process, and the high-voltage cable 200 is easier to install and construct on the periphery of the high-voltage cable 200.
Further, the wire-type temperature detector 12 is provided inside the high-voltage cable 200 in a wire-like shape. Referring to fig. 4, the components of the high voltage cable 200 generally include a conductor, an inner insulating layer, an inner protective layer, a filler (armor) and an outer insulation layer, the linear temperature detector 12 is used, and the linear temperature detector 12 is disposed inside the high voltage cable 200, that is, in the outer insulation layer of the high voltage cable 200, so that the linear temperature detector 12 is more attached to the inner conductor of the high voltage cable 200, thereby obtaining the wire temperature during the operation of the high voltage cable more accurately, and making the detection more accurate.
Specifically, the wire-type temperature detector 12 is an optical fiber temperature detector, and the optical fiber temperature detector is disposed in the high-voltage cable 200. The optical fiber sensing technology is developed along with the vigorous development of optical fiber communication in seventies of the last century, and compared with the traditional sensor, the optical fiber temperature detector adopting the optical fiber sensing technology has a series of advantages of light weight, corrosion resistance, high temperature resistance, water resistance, moisture resistance, electromagnetic interference resistance, easy integration, concealment and the like, and therefore, the optical fiber temperature detector has quite application in severe and complex environments. Besides the characteristics, the optical fiber sensing technology also has the capability of acquiring measured distribution information which changes with time and space in a sensing optical fiber area in real time. The optical fiber temperature detector can accurately measure the temperature, stress, bending, vibration and other information of any point on the optical fiber along the line, so that more accurate temperature data can be obtained. Meanwhile, since the optical fiber itself is thin and stable in properties, it does not affect the performance of the high voltage cable 200 even if it is installed inside the high voltage cable 200. By arranging the optical fiber temperature detector in the high-voltage cable 200, the optical fiber can accurately detect the high-voltage cable without affecting the transmission function of the high-voltage cable.
Further, referring to fig. 5, the surface temperature detector 13 is disposed corresponding to the position of the connector 201 of the high voltage cable 200 to obtain surface temperature data of the position of the connector 201 as the third temperature data. It should be noted that, in the link of high-voltage power transmission in the power system and other fields, a large number of bolts are needed at the joint 201 of the high-voltage cable 200 to connect two cables or the high-voltage cable 200 and equipment, and the junction is very easy to overheat, when the temperature exceeds a certain degree, the safe operation of the power grid is greatly damaged, so that the temperature at the joint 201 needs to be monitored in real time, so as to know whether the operation state of the power transmission line is normal. The surface temperature detector 13 is arranged corresponding to the position of the joint 201 of the high-voltage cable 200, so that temperature data at the joint 201 of the high-voltage cable 200 can be accurately obtained, abnormal conditions can be found in time, high-temperature damage to a power grid can be avoided, and in addition, the point temperature detector 11 and the line temperature detector 12 in the embodiment can be arranged at the joint 201 position and the high-voltage cable 200 section where the joint 201 is located. By providing the surface temperature detector 13 at the position of the joint 201 of the high voltage cable 200, the position of the joint 201, where the overheat phenomenon is likely to occur, can be detected, and the safe operation of the high voltage cable can be protected.
Specifically, the surface temperature detector 13 is an infrared imager, and the third temperature data is an infrared imaging chart. The infrared imager can image the whole object in real time in a 'face' mode, so that an operator can primarily judge the heating condition and the fault part through the image color and the hot spot tracking display function displayed by the screen, and then follow-up analysis is carried out, and the problem is confirmed with high efficiency and high accuracy. By installing the infrared imager at the position of the joint 201 of the high-voltage cable 200 to detect the temperature of the high-voltage cable, the normal work of the high-voltage cable is not affected while the temperature is accurately detected, and the installation and the construction are easier.
Further, the number of the surface-type temperature detectors 13 is at least two, and at least two of the surface-type temperature detectors 13 are disposed corresponding to different areas of the high-voltage cable 200.
In this embodiment, at least two of the surface temperature detectors 13 are disposed corresponding to the front surface area and the back surface area of the high voltage cable 200, respectively. As shown in fig. 5, it may be understood that when the infrared imager is disposed on one side, such as the front area, of the high-voltage cable 200, the infrared light emitted from the infrared imager cannot pass through the high-voltage cable 200, and the temperature of the other side, i.e., the back area, of the high-voltage cable 200 cannot be measured, so that the temperature measurement of the infrared imager is deviated, so that by disposing the surface-type temperature detectors 13 on the front area and the back area of the high-voltage cable 200, the surrounding detection of the high-voltage cable 200 by the surface-type temperature detectors 13 can be realized, the temperature detection of the high-voltage cable 200 can be more stereoscopic, and by disposing the surface-type temperature detectors 13 on the front area and the back area of the high-voltage cable, the accuracy of the temperature detection of the high-voltage cable can be more comprehensively and stereoscopically detected.
Referring to fig. 6, in another embodiment, the high voltage cable 200 includes at least two cable sets 210, each cable set 210 is configured to transmit a three-phase power signal, the first temperature data includes temperature data of three-phase cables of each cable set, and the second temperature data includes temperature data of three-phase cables of each cable set. As is well known, a three-phase circuit is a circuit composed of a three-phase power supply, a three-phase load, and a three-phase transmission line. The most basic structural feature of the circuit is that the circuit is provided with one or more groups of power supplies, each group of power supplies is composed of three sinusoidal power supplies with equal amplitude, equal frequency and identical phase difference, and the power supplies and the load adopt a specific connection mode. The three-phase circuit is widely applied to power systems such as power generation, power transmission, power distribution, high-power electric equipment and the like. In this embodiment, the high-voltage cable 200 includes at least two cable sets 210, each cable set 210 transmits a three-phase power supply signal, that is, each cable set 210 has at least three high-voltage cables 200 respectively transmitting three-phase power supply signals, so that the first temperature data includes the temperature data on the three-phase cables of each cable set 210 detected by the spot temperature detector 11, and the second temperature data includes the temperature data on the three-phase cables of each cable set 210 detected by the wire temperature detector 12. By detecting the first temperature data and the second temperature of the three-phase cable of each of the cable groups, the temperature detection of the high-voltage cable 200 can be made more accurate.
Referring to fig. 7, in another embodiment, each of the cable groups 210 includes a first phase cable 211, a second phase cable 212, and a third phase cable 213, the first phase cables 211 of at least two of the cable groups 210 are disposed adjacent to each other, the second phase cables 212 of at least two of the cable groups 210 are disposed adjacent to each other, the third phase cables 213 of at least two of the cable groups 210 are disposed adjacent to each other, the spot temperature detector 11 is disposed at the periphery of the first phase cables 211 of at least two of the cable groups 210 for outputting temperature data of the first phase cables 211 of at least two of the cable groups 210, and the wire temperature detector 12 is disposed at the periphery of each of the cables of at least two of the cable groups 210 for outputting temperature data of each of the cables. By providing the spot type temperature detector 11 at the outer periphery of the first phase cable 211 of at least two of the cable groups 210 and providing the wire type temperature detector 12 at the outer periphery of each cable of at least two of the cable groups 210, the accuracy of temperature detection can be improved.
