However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In the description of the present invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements at the same time. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0036] In one embodiment, see Figures 1 to 6 and Fig.10A waist-hanging power distribution network patrol system includes a waist belt 100, a first power distribution network patrol instrument 200 and a second power distribution network patrol instrument 300. The first power distribution network patrol instrument 200 is hung on the waist belt 100, and the first power distribution network patrol instrument 200 includes a first shell 210, a partial discharge tester, an infrared tester, and a noise tester 240. The partial discharge tester, the infrared tester and the noise tester 240 are all arranged on the first shell 210.

[0037] The second power distribution network patrol instrument 300 is hung on the belt 100. The second power distribution network patrol instrument 300 includes a second shell 310 and a gas concentration sensor chip 320. The gas concentration sensor chip 320 is attached to the outer wall of the second shell 310. The gas concentration sensor chip 320 is used to detect SF6 gas concentration, ozone gas concentration, CO2 gas concentration, CO gas concentration or oxygen concentration.

[0038] In the above-mentioned waist-hanging power distribution network inspection system, the belt 100 is fastened to the waist of the inspector, for example, and the first power distribution network inspection instrument 200 and the second power distribution network inspection instrument 300 are both hung on the belt 100, which is convenient to operate and easy to carry; in addition, the partial discharge tester, infrared tester and noise tester 240 are all concentrated in the same first shell 210, which has the functions of partial discharge test, infrared temperature measurement and noise test. For the inspectors, there is no need to carry multiple independent testers, nor to consider the battery power and charging problems of each tester, so that it is not only convenient to carry, but also convenient for the inspectors to use, which can greatly improve the efficiency of the inspection work; in addition, since the gas concentration sensor chip 320 is used and the gas concentration sensor chip 320 is installed on the outer wall of the second shell 310, while satisfying the gas detection, it can also greatly reduce the device volume of the second power distribution network inspection instrument 300, which is convenient for the staff to carry and improves the efficiency of the inspection work.

[0039] For further information, see Figures 1 to 3 The waist belt 100 is provided with a hook 110, and the first housing 210 is provided with a through hole, and the hook 110 passes through the through hole and is hung on the hook 110. The second housing 310 is provided with a hanging buckle 340 for hanging on the waist belt 100. In this way, the first power distribution network patrol instrument 200 and the second power distribution network patrol instrument 300 are both conveniently hung on the waist belt 100, and the operation is convenient.

[0040] In addition, the waist belt 100 is provided with one or more hanging loops 120. The hanging loops 120 can be used to hang water, flashlights, etc., so that the patrol personnel can carry more small items of this type without having to hold them in their hands, and it is also more convenient to use.

[0041] For further information, see Figures 4 to 9 The first power distribution network inspection instrument 200 also includes a first controller. The first controller is electrically connected to the partial discharge tester, the infrared tester and the noise tester 240 respectively, and the first controller is used to control any one of the partial discharge tester, the infrared tester and the noise tester 240 to work, and receive the test data of the tester. In this way, the inspection personnel can control the required tester to perform the test work through the first controller according to their own needs, and the operation is more convenient.

[0042] In one embodiment, see Figures 4 to 9 , the first shell 210 includes a hand-held portion 211 and an arc-shaped connecting portion 212; the two ends of the connecting portion 212 are respectively connected to the two ends of the hand-held portion 211; specifically, the first shell 210 is in a D-shape as a whole. In this way, the hand-held portion 211 can be convenient for inspectors to hold to perform relevant testing work, and the operation is convenient. In addition, it is also convenient for the hook 110 on the belt 100 to pass through the D-shaped mouth area to hang the hand-held portion 211, so as to facilitate the installation of the first shell 210 and facilitate carrying. In addition, optionally, the hand-held portion 211 is connected to the connecting portion 212 to form an integrated structure.

[0043] In one embodiment, see Figures 4 to 9 , the infrared tester is arranged in the connecting part 212. The infrared tester includes an infrared camera 231 and a positioning laser transceiver 232 located on the side of the connecting part 212 facing away from the handheld part 211. The positioning laser transmitter is used to project a laser point on the device to be tested and obtain the distance information from the positioning laser transmitter to the device to be tested. The infrared camera 231 and the positioning laser transceiver 232 are arranged adjacent to each other, and the infrared camera 231 is used to obtain the infrared imaging picture information of the device to be tested. In this way, when the infrared tester is working, the infrared camera 231 obtains the infrared imaging picture information of the device to be tested, and the positioning laser transceiver 232 synchronously projects the laser point on the component to be tested of the device to be tested. The infrared tester can judge the temperature information of the component to be tested of the device to be tested according to the infrared imaging picture information (including the laser point projected on the component to be tested), and then can measure the heating condition of the device to be tested and whether there is a heating point.

[0044] In one embodiment, see Figures 4 to 9, a push-type control switch 213 is provided on the first shell 210, and the push-type control switch 213 is electrically connected to the first controller. Specifically, the push-type control switch 213 is set in the form of a grab handle, and the grab handle can be convenient for the patrol personnel to perform manual pressing operations. When the grab handle is manually pressed, the push-type control switch 213 is connected accordingly, and a control signal is sent to the first controller, and the first controller controls the positioning laser transceiver 232 to emit a laser point or calculate and record the distance from the positioning laser transmitter to the device to be tested. In addition, the push-type control switch 213 is specifically arranged at the end of the side of the hand-held part 211 facing the connecting part 212, and is also located in the area surrounded by the hand-held part 211 and the connecting part 212, so that it is convenient for the patrol personnel to perform the pressing operation. In addition, when the push-type control switch 213 is pressed different times, the first controller executes different commands. For example, when the push-type control switch 213 is pressed once, the first controller controls the positioning laser transceiver 232 to emit laser and hits the laser point on the device to be tested; when the push-type control switch 213 is pressed again, the first controller controls the positioning laser transceiver 232 to stop emitting laser; when the push-type control switch 213 is pressed twice in succession, the first controller calculates and records the distance from the positioning laser transmitter to the device to be tested.

[0045] In one embodiment, see Figures 4 to 9 , the noise tester 240 is arranged on the side of the connecting portion 212 facing away from the handheld portion 211. In this way, the noise tester 240 can better test the noise situation in the power room. As an optional solution, the noise tester 240 can also be arranged at other parts of the first housing 210, for example, on the handheld portion 211.

[0046] In one embodiment, see Figures 4 to 9 , the partial discharge tester includes a geoelectric wave tester 221 and an ultrasonic tester 222. The geoelectric wave tester 221 and the ultrasonic tester 222 are respectively arranged on the end faces of the handheld part 211. In this way, the geoelectric wave tester 221 can test the geoelectric wave information emitted by the device to be tested, and the partial discharge condition of the device to be tested can be determined based on the tested geoelectric wave information; the ultrasonic tester 222 can correspondingly test the ultrasonic information emitted by the device to be tested, and the partial discharge condition of the device to be tested can also be determined based on the tested ultrasonic tester 222. Among them, when the patrol personnel hold the handheld part 211 in a normal posture, the end faces of the handheld part 211 are both in the horizontal plane, and the geoelectric wave tester 221 and the ultrasonic tester 222 are also in the horizontal plane accordingly, so that the geoelectric wave tester 221 and the ultrasonic tester 222 have a better testing effect.

[0047] In one embodiment, the first controller includes a switching control switch 250 disposed on the first housing 210. The switching control switch 250 is used to control the operation of the partial discharge tester, the infrared tester or the noise tester 240. Specifically, the switching control switch 250 can be a hand-push shift type switching control switch 250, a touch screen switching control switch 250, or a press type switching control switch 250, which will not be described in detail.

[0048] For further information, see Figures 4 to 9 , the first housing 210 is provided with 6 working gears, which are respectively the closing gear 214, the noise test gear 215, the infrared test gear 216, the ultrasonic test gear 217, the ground wave test gear 218 and the automatic gear 219. The switching control switch 250 is specifically a hand-push shifting switching control switch 250. When the switching control switch 250 is in the closing gear 214, the testers on the first housing 210 do not perform testing; when the switching control switch 250 is moved to the noise test gear 215, the noise tester 240 performs noise testing; when the switching control switch 250 is moved to the infrared test gear 216, the infrared tester performs infrared testing; when the switching control switch 250 is moved to the ultrasonic test gear 217, the ultrasonic tester 222 performs ultrasonic testing; when the switching control switch 2 50 When the ground wave test gear 218 is moved, the ground wave tester 221 performs the ground wave test; when the switching control switch 250 is moved to the automatic gear 219, the terminal control device, such as a mobile phone, computer or tablet, communicates with the first power distribution network patrol instrument 200 to control the various testers of the first power distribution network patrol instrument 200 to work, and the terminal control device can control the noise tester 240, infrared tester, ultrasonic tester 222 and any one of the ground wave tester 221 to perform testing according to its own needs, and obtain the test data of the tester.

[0049] In one embodiment, see Figures 4 to 9, the first housing 210 is also provided with a first data interface 260 electrically connected to the first controller. The first data interface 260 is used to electrically connect to a control device or a power supply device. Specifically, the first data interface 260 uses a universal USB interface, which is convenient for connecting to a mobile phone, a computer or a tablet through, for example, a USB data cable 400. In this way, after the first data interface 260 is connected to the control device or the power supply device through the data cable 400, the control device (such as a mobile phone, a computer, a tablet or the second power distribution network patrol instrument 300) or the power supply device (such as a power bank) supplies power to each tester of the first power distribution network patrol instrument 200, and the first power distribution network patrol instrument 200 does not need to be equipped with a battery; in addition, each tester of the first power distribution network patrol instrument 200 is connected to the power supply through the first data interface 260, so that each tester of the first power distribution network patrol instrument 200 does not need to be equipped with a battery, so that the structure is simplified and convenient for patrol personnel to carry.

[0050] In one embodiment, see Figures 10 to 13 The second power distribution network inspection instrument 300 also includes a second controller and a prompt device 330. The prompt device 330 is arranged on the second shell 310. The prompt device 330 and the gas concentration sensor chip 320 are both electrically connected to the second controller. The second controller is used to control the prompt device 330 to perform a prompt operation when the gas concentration detected by the gas concentration sensor chip 320 is not within the preset range. In this way, when the second power distribution network inspection instrument 300 is used to inspect the power distribution network, if the gas concentration sensor chip 320 detects that the SF6 gas concentration, ozone gas concentration, CO2 gas concentration, CO gas concentration or oxygen concentration is not within the preset range, for example, the SF6 gas concentration, ozone gas concentration, CO2 gas concentration or CO gas concentration exceeds the specified value, or the oxygen concentration is lower than the fixed value, the second controller controls the prompter to perform a prompt operation accordingly, and the staff avoids or prepares countermeasures in advance according to the prompt, which greatly improves safety.

[0051] It is understandable that the preset ranges of SF6 gas concentration, ozone gas concentration, CO2 gas concentration, CO gas concentration and oxygen concentration can be set according to actual conditions. Specifically, for example, the SF6 gas concentration is not greater than 6g / m 3 When the SF6 gas concentration in the power room is detected to be greater than 6g / m 3 When the ozone concentration is less than 260 μg / m 3 When the ozone concentration in the power room is detected to be greater than 260μg / m 3When the concentration of CO2 in the power room is greater than 3%, the prompt device 330 performs a prompt operation, thereby avoiding the adverse phenomena such as fatigue, coughing, chest tightness and pain, skin wrinkling, nausea and headache, accelerated pulse, memory loss, and decreased vision caused by the staff working beyond the concentration range; for another example, the CO2 gas concentration is not greater than 3%. When the CO2 gas concentration in the power room is detected to be greater than 3%, the prompt device 330 performs a prompt operation, thereby avoiding the adverse phenomena such as damage to the human respiratory organs, poisoning of the body, and suffocation and death caused by the staff working beyond the concentration range; for another example, the CO gas concentration is not greater than 57mg / m 3 When the CO gas concentration in the power room is detected to be greater than 57 mg / m 3 When the oxygen concentration in the power room is detected to be lower than 19.5%, the prompt device 330 performs a prompt operation, thereby avoiding adverse phenomena such as fainting and suffocation caused by the staff working in the hypoxic range.

[0052] For further information, see Figures 10 to 13 The prompt device 330 is a speaker, a flashing light or a vibration mechanism. When it is detected that the gas concentration is not within the preset range, the prompt device 330, for example, gives a voice prompt to the staff through a speaker, or gives a prompt to the staff through frequent flashing of a flashing light, or gives a prompt to the staff through vibration of a vibration mechanism.

[0053] In one embodiment, see Figures 10 to 13 , the gas concentration sensor chips 320 are multiple, and the multiple gas concentration sensor chips 320 are used to detect the concentration of multiple gases in SF6, ozone, CO2, CO and oxygen. Specifically, there are five gas concentration sensor chips 320, and the five gas concentration sensor chips 320 are used to detect the concentration of SF6, ozone, CO2, CO and oxygen. In this way, on the one hand, the second power distribution network patrol instrument 300 can realize the concentration detection of multiple gases in SF6, ozone, CO2, CO and oxygen, and the detected gas concentration information is more comprehensive, thereby improving safety; on the other hand, the concentration detection of multiple gases is respectively carried out by using corresponding gas concentration sensor chips 320, and the multiple gas concentration sensor chips 320 are all assembled on the outer wall of the second shell 310, which is convenient for the staff to carry. The staff does not need to carry multiple separate gas concentration detection devices to carry out patrol work, and the patrol work efficiency can be greatly improved, and the patrol intensity of the staff is reduced.

[0054] In one embodiment, see Figures 10 to 13, multiple gas concentration sensor chips 320 are arranged on the same side of the second shell 310. Further, as an optional solution, the outer wall of the second shell 310 is also equipped with an openable protective cover, and the protective cover is arranged outside the multiple gas concentration sensor chips 320. In this way, when the second power distribution network patrol instrument 300 is not working, the protective cover is arranged outside the multiple gas concentration sensor chips 320, which plays a protective role for the multiple gas concentration sensor chips 320 and prevents the gas concentration sensor chips 320 from being damaged; when the second power distribution network patrol instrument 300 is performing patrol work, the protective cover can be opened.

[0055] In one embodiment, the second shell 310 is provided with a wiring hole, the second controller is disposed in the second shell 310, and the signal line of the gas concentration sensor chip 320 passes through the wiring hole and is electrically connected to the second controller.

[0056] In one embodiment, see Figures 10 to 13 The second power distribution network inspection instrument 300 also includes a power bank. The power bank is disposed in the second housing 310, and the power bank is electrically connected to the gas concentration sensor chip 320, the second controller, and the prompt device 330, respectively. In this way, the power bank can supply power to the gas concentration sensor chip 320, the second controller, and the prompt device 330, respectively. In order to achieve a more durable power supply, the power bank uses, for example, a battery with an ultra-large capacity.

[0057] Generally, the equipment used for power distribution network inspections is mostly electronic equipment (including mobile phones). Due to long hours of working outside, the batteries of electronic equipment are easily exhausted and unable to continue working.

[0058] For further information, see Figures 10 to 13 The second housing 310 is provided with a plurality of charging interfaces 312, and the charging interfaces 312 are electrically connected to the power bank. The charging interface 312 is specifically a USB interface, which is a universal interface that can be conveniently electrically connected to other electronic devices for power supply or charging.

[0059] In one embodiment, see Figures 10 to 13, a second data interface 313 is also provided on the second housing 310. The second data interface 313 is electrically connected to the second controller, and the second data interface 313 is also used to electrically connect to the first power distribution network patrol instrument 200. In this way, after the first data interface 260 of the first power distribution network patrol instrument 200 is connected to the second data interface 313 of the second power distribution network patrol instrument by the data line 400, on the one hand, the first power distribution network patrol instrument 200 sends the detected detection data to the second power distribution network patrol instrument 300 through the second data interface 313, and stores the detection data through the second controller of the second power distribution network patrol instrument 300, sends it to the user's mobile phone or sends it to the terminal device (such as a PC); on the other hand, after the first power distribution network patrol instrument 200 is electrically connected to the second data interface 313, the second data interface 313 can power or charge the first power distribution network patrol instrument 200, which can extend the working time of the first power distribution network patrol instrument 200.

[0060] In one embodiment, see Figures 1 to 3 ,and Figures 10 to 13 The second housing 310 is also provided with a third data interface 314. The third data interface 314 is electrically connected to the second controller, and the third data interface 314 is also used to electrically connect to a mobile phone. In this way, after the mobile phone is electrically connected to the third data interface 314 through the data line 400, the detection data can be obtained, and the second power distribution network patrol instrument 300 can also be controlled, for example, the preset range of gas concentration can be adjusted through the mobile phone.

[0061] In one embodiment, see Figures 10 to 13 The second housing 310 is also provided with a data transceiver antenna 315. The second controller is electrically connected to the data transceiver antenna 315. Thus, the second controller wirelessly sends the detection data to the terminal device through the data transceiver antenna 315, which is convenient for remote control.

[0062] In one embodiment, see Figures 10 to 13 The second housing 310 is also provided with a power display module 316. The power display module 316 is electrically connected to the power bank, and is used to display the current power of the power bank. Specifically, the power display module 316 is a display screen or a display light. The current power of the power bank is displayed by the power display module 316, so that the staff can understand the power status of the power bank.

[0063] In one embodiment, see Figures 10 to 13, a power switch button 317 is also provided on the second housing 310. The power switch button 317 is set on the power supply circuit of the power bank. When the power switch is turned on, the power bank provides power to the second controller, the gas concentration sensor chip 320 and the prompt device 330, and the second controller, the gas concentration sensor chip 320 and the prompt device 330 work normally; when the power switch is turned off, the power supply circuit of the power bank is disconnected, and the second controller, the gas concentration sensor chip 320 and the prompt device 330 no longer work, thereby avoiding the power waste of the power bank.
