DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

If the specific posture changes, the directional indication will also change accordingly.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

Taking "A and / or B as an example", it includes solution A, or solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] In the field of power detection and maintenance, due to reasons such as not being allowed to operate after a ground fault, the defective grounding of the porcelain bottle cannot be fully ablated, resulting in frequent intermittent tripping faults caused by deteriorated insulators in the distribution network. This problem plagues the troubleshooting of distribution network faults, increases the troubleshooting time, has a great impact on the control of distribution network fault rate and the improvement of power supply reliability, and seriously restricts the realization of production goals.

[0033] However, for intermittent tripping faults, traditional troubleshooting methods such as manual inspections are mainly relied on, which takes a long time to troubleshoot, is inefficient, and it is difficult to accurately locate the tower where the deteriorated insulator exists. For lightning faults, there is a lack of effective auxiliary detection methods, making it difficult to arrange lightning protection measures in advance to prevent the formation of lightning faults.

[0034] In view of this, the present application provides a power fault detection system for solving the inefficient and incomplete technical problems in the prior art. In order to achieve one or part or all of the above purposes or other purposes, the present application proposes a power fault detection system and its installation method, wherein the power fault detection system includes a live installation device and a current monitoring device. The live installation device includes a grounding wire, a connecting assembly, a grounding pin and an insulating operating rod. The connecting assembly is fixed to the side of the tower away from the ground, and connects the insulating operating rod and one end of the grounding wire. The grounding pin is arranged on the ground, and the other end of the grounding wire is connected to the grounding pin; the current detection device includes a structural assembly, a detection assembly and a data processing assembly. The structural assembly is fixedly connected to the side of the tower close to the ground, the detection assembly and the data processing assembly are arranged on the structural assembly, and the detection assembly is electrically connected to the grounding wire and the data processing assembly.

[0035] The following will be combined Figures 1 to 5 , the power fault detection system provided in the embodiment of the present application is described in detail through specific examples.

[0036] Please also read Figures 1 to 5 , Figure 1 A schematic diagram of the structure of the power fault detection system provided in the embodiment of the present application Figure 1 ; Figure 2 A partial schematic diagram of a power fault detection system provided in an embodiment of the present application Figure 1 ; Figure 3 A partial schematic diagram of a power fault detection system provided in an embodiment of the present application Figure 2 ; Figure 4 for Figure 3 A schematic diagram of the structure of the power fault detection system as viewed from above is shown; Figure 5 for Figure 3The schematic diagram of the internal structure of the waterproof box of the power fault detection system shown. One embodiment of the present invention proposes a power fault detection system 100, including a live installation device 10 and a current monitoring device. The live installation device 10 includes a grounding wire 11, a connecting component 13, a grounding pin 15 and an insulating operating rod 17. The connecting component 13 is fixed to the side of the tower away from the ground, and connects the insulating operating rod 17 with one end of the grounding wire 11. The grounding pin 15 is set on the ground, and the other end of the grounding wire 11 is connected to the grounding pin 15; the current detection device 30 includes a structural component 31, a detection component 33 and a data processing component 35. The structural component 31 is fixedly connected to the side of the tower close to the ground. The detection component 33 and the data processing component 35 are arranged on the structural component 31, and the detection component 33 is electrically connected to the grounding wire 11 and the data processing component 35.

[0037] It can be understood that the live installation device 10 in the circuit fault detection system is used in the process of power fault detection, and the connection component 13 fixed on the side of the pole tower away from the ground is connected to one end of the ground wire 11, and the other end of the ground wire 11 is connected to the ground pin 15, and the ground pin 15 is inserted into the ground according to the preset position. In this way, the inherent power grid network usually set on the pole tower can have a grounding branch through the connection component 13, the ground wire 11 and the ground pin 15. On the other hand, the process of installing the connection component 13 from the ground or other positions on the side of the pole tower away from the ground can be achieved by the insulating operating rod 17 in the live installation device 10. Specifically, the operation and maintenance personnel who implement this maintenance process can hold and fix one end of the insulating operating rod 17 by hand with insulating gloves or other means, and control the movement trajectory of the insulating operating rod 17 so that the insulating operating rod 17 drives the other end of the fixed connection component 13 to move relatively, so that the connection component 13 can be flexibly fixed at a fixed position on the side of the pole tower away from the ground. The live installation device 10 using the insulating operating rod 17 realizes the live installation process of the circuit fault detection system, so that the on-site layout process of the system does not affect the power supply reliability. During the device installation and / or troubleshooting process, there is no need to power off other power lines of the power grid fixed on the tower, thereby reducing the local power outage time that may be caused by device installation and troubleshooting, improving the power supply reliability of the power grid using the circuit fault detection system, and also improving the flexibility and economy of the use of the power grid fault detection system.

[0038] It should be noted that at least one end of the insulating operating rod 17 away from the connecting component 13 has an insulating material, and the insulating material can specifically be polyethylene, polyvinyl chloride, silicone rubber, polytetrafluoroethylene, epoxy resin, phenolic resin or a composite material, etc. This application does not make any specific limitations on this.

[0039] It can be understood that the power monitoring device in the circuit fault detection system is used in the process of power fault detection to provide a certain detection capability for intermittent and concealed insulator grounding faults, and to provide a certain auxiliary detection means for lightning flashover to the ground, so that the operation and maintenance personnel can arrange lightning protection measures according to the detection situation, improve the detection efficiency of insulator grounding faults, and effectively prevent the formation of lightning faults, and further improve the fault handling efficiency and accuracy of the power fault detection system 100. Specifically, the process of the power detection device detecting the power grid relies on the detection component 33 to detect the current and / or voltage parameters in the grounding wire 11 led by the pole tower top connection component 13, so as to indirectly obtain the working state of the power grid formed on the pole tower in the local area. Further, when the detected current and / or voltage parameters cannot intuitively display the specific conditions and faults, the data processing component 35 electrically connected to the detection component 33 can obtain the parameters obtained by the detection component 33 and process them, so as to present the detection results more intuitively, thereby improving the fault handling efficiency and accuracy of the power fault detection system 100.

[0040] On the other hand, the structural component 31 of the current detection device 30 is used to fix the monitoring component and the data processing component 35, so that the monitoring component and / or the data processing component 35 can have a relatively fixed position relationship with the pole tower, while avoiding the influence of factors such as dust, droplets, etc. in the external environment on the precision electronic devices in the monitoring component and / or the data processing component 35, thereby improving the use stability of the current monitoring device and the power fault detection system 100.

[0041] As a possible implementation, please also refer to Figure 1 and Figure 2 The power grid tower includes a flat iron, and the connecting assembly 13 includes a fixed clamping member 131 and an insulating rod connecting member 133. The fixed clamping member 131 is fixed to the flat iron, and the grounding wire 11 is connected to the fixed clamping member 131; the insulating rod connecting member 133 is fixed to the fixed clamping member 131, and the end away from the fixed clamping member 131 is detachably connected to the insulating operating rod 17.

[0042] It is understandable that the flat iron of the power grid tower is usually set at the top of the tower and used for connecting the power grid line between two adjacent towers. It usually has a flat plate-shaped part to facilitate the clamping or fixing of other detection devices. The connection method of the fixed clamping member 131 and the insulating dry connector is a detachable connection, which can be a bolt connection, a snap connection, a key connection, a threaded connection, a quick release connection, a flange connection or a pin connection, etc. This application does not make specific restrictions on this. The fixing method of the fixed clamp 131 and the flat iron is also detachable, so that the operation and maintenance personnel can detachably fix the fixed clamp 131 to the preset position of the flat iron through the insulating rod connector 133 to electrically connect the two, and then separate the insulating rod connector 133 from the fixed clamp 131 through a detachable connection, so that the fixed clamp 131, the grounding wire 11 and the grounding pin 15 form a complete grounding wire 11 and avoid the possible influence of the insulating rod connector 133 on the line, while ensuring the accuracy of the current detection effect of the current monitoring device, further increase the flexibility and efficiency of use of the power fault detection system 100.

[0043] As a possible implementation, see Figure 1 and Figure 2 The fixed engaging member 131 is formed with a engaging groove 131a, the flat iron abuts against one side wall of the engaging groove 131a, and a through first mounting hole 131b is formed on the other side wall of the engaging groove 131a. The insulating rod connecting member 133 is passed through the first mounting hole 131b and abuts against the flat iron.

[0044] It can be understood that the first mounting hole 131b in the clamping groove 131a is used to guide the movement trajectory of the insulating rod connecting piece 133. In this way, the insulating rod connecting piece 133 passing through the first mounting hole 131b can move along the direction of the first mounting hole 131b to approach and clamp the flat iron, or move away from the flat iron to separate the fixed clamping piece 131 from the flat iron. In this way, there is no need to set up other structures or add other components. The installation and disassembly process of the fixed clamping piece 131 and the flat iron can be realized through the displacement process of the insulating rod connecting piece 133, further improving the installation efficiency of the fixed clamping piece 131 and the live installation device 10, thereby improving the use efficiency of the power fault detection system 100.

[0045] Preferably, the cross-section of the clamping groove 131a can be U-shaped, and the flat iron abuts against the smooth end surface on one side of the clamping groove 131a, and the end surface of the insulating rod connecting piece 133 close to the flat iron is set corresponding to the shape of the end surface of the flat iron on this side. In this way, the clamping effect of the fixed clamping piece 131 and the insulating rod connecting piece 133 on the flat iron is further increased when the fixed clamping piece 131, the flat iron and the insulating rod connecting piece 133 abut against each other.

[0046] As a possible implementation, see Figure 1and Figure 2 The fixed engaging member 131 is further formed with a second mounting hole 131c, which is spaced apart from the engaging groove 131a. The connecting assembly 13 further includes a fastener 135, which is passed through the second mounting hole 131c to fix the grounding wire 11 and the fixed engaging member 131.

[0047] It can be understood that the second mounting hole 131c and the corresponding fastener 135 are used to fix the grounding wire 11 and the fixed clamp 131. Specifically, the fastener 135 and the second mounting hole 131c can be fixed in a detachable connection manner such as screw connection, clamping, plug-in connection or pin connection. In this way, before the working process of the power fault detection system 100, the grounding wire 11 and the fixed clamp 131 can be fixed in advance so that the two have a relatively fixed positional relationship. Alternatively, during the working process of the power fault detection system 100, the grounding wire 11 and / or the fixed clamp 131 with different performance parameters can be replaced according to actual conditions without replacing the two together, thereby further improving the flexibility and economy of the use of the live installation device 10.

[0048] It should be noted that the extension direction of the second mounting hole 131c, which is spaced apart from the snap-in slot 131a, can be perpendicular to the extension direction of the first mounting hole 131b arranged in the snap-in slot 131a. In this way, during the use of the live installation device 10, the connection process of the flat iron, the fixed snap-fit ​​component 131 and the insulating rod connecting component 133 corresponding to the first mounting hole 131b and the connection process of the fixed snap-fit ​​component 131 and the grounding wire 11 corresponding to the second mounting hole 131c both have a large non-overlapping operating range, thereby improving the use flexibility and stability of the live installation device 10 and the power fault detection system 100.

[0049] As a possible implementation, see Figures 1 to 5 The structural component 31 includes a waterproof box 311 and a waterproof box 313. The waterproof box 311 is fixedly connected to the power grid tower, and a first accommodating chamber 311a is formed in the waterproof box 311, and the data processing component 35 is arranged in the first accommodating chamber 311a; the waterproof box 313 is fixedly connected to the waterproof box 311, and a second accommodating chamber 313a communicating with the first accommodating chamber 311a is formed, the detection component 33 is arranged in the second accommodating chamber 313a and is electrically connected to the data processing component 35, and the grounding wire 11 is passed through the waterproof box 313 and is electrically connected to the detection component 33.

[0050] It is understandable that the material of the waterproof box 311 and the waterproof box 313 can be plastic, fiberglass, polyurethane, polypropylene or synthetic rubber and other common water-resistant materials, which can be set according to different application requirements and use environments, and this application does not make specific restrictions on this. The waterproof box 311 is used to enclose a first accommodating chamber 311a to accommodate the data processing component 35, and the waterproof box 313 is used to enclose a second accommodating chamber 313a to accommodate the detection component 33. The first accommodating chamber 311a and the second accommodating chamber 313a are connected to each other so that the detection component 33 can be electrically connected to the data processing component 35. The waterproof box 311 and the waterproof box 313 are used to isolate the influence of environmental factors such as dust or droplets in the external environment on the precision electronic components that may exist in the monitoring component and the data processing component 35, and further increase the stability and service life of the data processing component 35, the monitoring component and the current monitoring device.

[0051] It is understandable that the fixed connection method of the waterproof box 311 and the waterproof box 313, which are respectively set, can be bonding, clamping, welding, bolting or plugging, etc., and this application does not make specific restrictions on this. In this way, the waterproof box 311 and the data processing component 35 set therein can be replaced according to different application scenarios, or the waterproof box 313 and the monitoring component set therein can be replaced flexibly when any of the data processing component 35 or the detection component 33 fails, without replacing the components in the other box body / box body, further increasing the flexibility and economy of the current monitoring device and the power fault detection system 100.

[0052] As a possible implementation, see Figure 5 The current detection device 30 also includes a charging board 37, which is fixedly connected to the top wall of the waterproof box 311 and electrically connected to the data processing component 35; and / or, the current detection device 30 also includes a storage battery 39, which is arranged in the first accommodating cavity 311a and electrically connected to the data processing component 35.

[0053] It should be noted that the charging plate 37 can be a solar charging plate 37 that converts solar energy in the external environment into electrical energy based on the photovoltaic effect and inputs it into the internal part. In this way, the charging plate 37 can provide the data processing component 35 electrically connected thereto with the electrical energy required for normal operation, thereby avoiding the possibility that the data processing component 35 cannot process data normally due to insufficient power supply, and increasing the working stability of the current monitoring device and the power fault detection system 100. On the other hand, the charging plate 37 fixed to the top wall of the waterproof box 311 has a larger surface area than the waterproof box 313 corresponding to the volume of the waterproof box 311, thereby ensuring that the charging plate 37 is firmly fixed while increasing its photoelectric conversion efficiency as much as possible, thereby improving the use efficiency of the current monitoring device.

[0054] It can be understood that the energy storage battery 39 arranged inside the first accommodating cavity 311a is a device that can store electrical energy and release electrical energy when needed. It is also used together with the charging plate 37 to provide the electrically connected data processing component 35 with the electrical energy required for normal operation, thereby avoiding the possibility that the data processing component 35 cannot process data normally due to insufficient power supply, and increasing the working stability of the current monitoring device and the power fault detection system 100.

[0055] As a possible implementation, see Figures 1 to 5 The current detection device 30 also includes a display screen 36 , which is embedded in the bottom wall of the waterproof box 311 and electrically connected to the data processing component 35 .

[0056] It is understandable that the display screen 36 is a common user-circuit interaction method in the field, which is used to characterize the internal working state of the power supply device and the possible detection data of the ground wire 11 by the detection component 33. For example, a current or voltage sensor is set by the detection component 33, which collects the required data and is then processed by the data processing component 35 and then transmitted to the display screen 36, and presented to the operation and maintenance personnel in a form that can be distinguished by the naked eye. In this way, while increasing the user experience, the flexibility of use of the current monitoring device and the power fault detection system 100 is further improved.

[0057] As a possible implementation, see Figures 1 to 5 The structural component 31 also includes a cable tie 32, which is looped around the power grid tower to fix the power grid tower and the waterproof box 311; and / or, the current detection device 30 also includes a waterproof switch 38, which is arranged on the bottom wall of the waterproof box 311 and is electrically connected to the data processing component 35.

[0058] It should be noted that the cable tie 32 is a belt-like object made of plastic or metal commonly used in the art, and is mainly used to tie and fix items. Compared with methods such as clamping, bolting or plugging, it has a better fixing effect and a lower cost, and can be reused many times, further increasing the flexibility of use of the structural assembly 31. Preferably, the number of cable ties 32 can be at least two groups, and at least two groups of cable ties 32 are arranged at intervals along the height direction. In this way, the multiple groups of cable ties 32 are respectively arranged around the power grid tower to achieve the fixation of the tower and the waterproof box 311, further improving the stability of use of the structural assembly 31.

[0059] It is understandable that the waterproof switch 38 disposed on the wall of the waterproof box 311 realizes the control effect of the electrically connected data processing component 35 through physical actions such as opening and closing, without opening the waterproof box 311 or additionally adjusting other components so that the operation process contaminates the data processing component 35 accommodated in the first accommodating chamber 311a, further improving the working stability of the current monitoring device. Furthermore, the waterproof switch 38 is provided with sealing materials and special structures to achieve the waterproof and dustproof functions of preventing droplets and dust from entering the first accommodating chamber 311a. At the same time, it is arranged on the bottom wall of the waterproof box 311, and compared with other parts of the waterproof box 311, it has a closer distance to the ground, which is more friendly to the operation of the operation and maintenance personnel, and the waterproof switch 38 can be operated without the help of other auxiliary tools. In this way, the use stability and flexibility of the current monitoring device and the power fault detection system 100 are further improved.

[0060] As a feasible implementation, the detection component 33 includes a fast saturation through-type current transformer, and the grounding wire 11 is arranged through the fast saturation through-type current transformer.

[0061] It should be noted that the fast saturation through-type current transformer is a specially designed current transformer, which combines the installation convenience of the through-type current transformer and the fast response characteristics of the fast saturation current transformer. Especially in the case of rapid detection and response to short circuit and other faults, it can provide accurate current signals to protect the safe and stable operation of power equipment and systems. In this way, the detection effect of the sudden change in the instantaneous fault of the insulator is improved in a targeted manner, and the fault display efficiency of the power fault detection system 100 is improved.

[0062] As a feasible embodiment, the data processing component 35 includes an Internet of Things transmission module. When the data processing component 35 obtains the relay change signal when the abnormal current changes transmitted by the detection component 33, the signal is used as a trigger signal. The Internet of Things transmission module transmits the detection information to a preset address through a wireless network so that the operation and maintenance personnel can obtain it, further improving the detection efficiency and usage flexibility of the power fault detection system 100.

[0063] See also Figure 6 The technical solution of the present invention also proposes an installation method, which is applied to the power fault detection system 100 as any one of the above-mentioned embodiments. The specific structure of the power fault detection system 100 refers to the above-mentioned embodiments.
