Description

Technical Field

[0001] The present application relates to the technical field of power transformation equipment, and in particular to a grounding device with a long-term power testing function and a power testing control method thereof. Background Art

[0002] In the field of electric power, in traditional grounding operations, operators need to perform an electrical test before hanging the ground wire. However, cumbersome operations or negligence may result in failure to perform an electrical test or inaccurate electrical test, and the power may be reversed through an abnormal path. If the equipment or line is still energized, the suddenly hanging ground wire may cause the operator to get an electric shock and cause a safety accident. In addition, incorrectly hanging the ground wire when the equipment is energized may also cause equipment damage or further electrical accidents.

[0003] In some cases, the transmission line is not energized after power testing, but an unexpected power outage may occur after a long time interval. If the ground wire is not immediately connected and the operation is repeated, there may be a risk of connecting incorrectly, resulting in the aforementioned personal safety accidents, equipment damage, or electrical accidents.

[0004] In the prior art, in order to solve the above problems, when hanging the ground wire, the electrical test operation generally adopts an integrated device of contact and induction testers or a direct-swing grounding switch. The integrated device of contact and induction testers improves the operating efficiency by building two types of testers into the insulating operating rod, but the cost is high. The direct-swing grounding switch simplifies the operating process, reduces labor intensity, and is suitable for frequent power system maintenance occasions. The above two schemes have their own characteristics, and the appropriate equipment type can be selected according to specific needs. However, the above two schemes have limitations on functions such as real-time reminders and early warnings, which will affect the staff's judgment of the live line status during work, and there are still safety hazards in actual operations. Summary of the invention

[0005] In view of this, the present application provides a grounding device with a long-term electrical testing function and an electrical testing control method thereof, which are used to solve the technical problem in the prior art that the grounding device cannot provide real-time reminders and warnings, and there are safety hazards.

When the threaded rod moves, the clamp is driven to form a clamping opening between the clamp and the top of the monkey clamp body for clamping or loosening the power transmission line. Since the threaded rod is connected to the insulating rod through a fixed head, the threaded rod can be driven to rotate by rotating the insulating rod, so that the threaded rod drives the clamp to approach or move away from the top of the monkey clamp, thereby clamping or loosening the power transmission line.

[0037] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0038] Reference Figures 1 to 3 The embodiment of the present application provides a grounding device with a long-term electrical testing function, comprising an insulating rod 10, a wire hanging device for hanging wires arranged at the first end of the insulating rod 10, and also comprising an electrical testing module 20 arranged in the insulating rod 10, a power supply module 21 electrically connected to the electrical testing module 20, an electrical testing contact 22 electrically connected to the electrical testing module 20 and capable of conducting with the wires on the wire hanging device, and an operating panel 23 electrically connected to the electrical testing module 20 and arranged outside the insulating rod 10, wherein a control switch 24 is provided on the operating panel 23, and an alarm device 25 is also provided on the operating panel 23.

[0039] In this embodiment, an electrical testing module 20, a power module 21, an operation panel 23 and an alarm device 25 are arranged in the insulating rod 10 to realize a multifunctional integrated design, which not only simplifies the carrying and use of the equipment, but also improves the operating efficiency and convenience; and the electrical testing module 20 is connected to the power module 21, which has a long-term electrical testing function and can still accurately detect the live state of the line or equipment after a long time interval. When reverse power transmission is detected in the line, the alarm device 25 automatically sends an alarm signal to promptly remind the operating personnel to take corresponding measures to eliminate potential safety hazards, thereby providing protection for the safety of the operating personnel.

[0040] Specifically, in this embodiment, the insulating rod 10 is a hollow cylindrical structure, and the inner cavity therein is used to place the above-mentioned electrical test contact 22, the operation panel 23, the electrical test module 20 and the power module 21. Of course, the insulating rod 10 can also be set as a square rod or a square tube. The insulating rod 10 is set as a hollow structure, which also reduces its weight and is convenient for carrying and operation. In this embodiment, the insulating rod 10 has a first end and a second end, and the end where the hanging wire device is located is defined as the first end, and the other end opposite thereto is defined as the second end. The above-mentioned electrical test contact 22, the operation panel 23, the electrical test module 20 and the power module 21 are arranged in sequence from the first end to the second end. In this way, the electrical test contact 22 is close to the hanging wire device, which facilitates the electrical test device to directly contact the transmission line on the hanging wire device for electrical test detection, and facilitates wiring in the inner cavity of the insulating rod 10, making its internal layout more reasonable, convenient for installation and subsequent inspection and maintenance.

[0041] In this embodiment, the electrical testing module 20 further includes a positioning detection circuit, a sensing unit for sensing electrical signals, a processing unit for analyzing and comparing the electrical signals, an anti-interference circuit connected to the processing unit, and an automatic power-off protection circuit.

[0042] In this embodiment, the positioning detection circuit can sense whether the grounding device is located on the transmission line to be detected. When the grounding device is connected to the transmission line to be detected, the electrical testing module performs an electrical testing operation. When the electrical testing module is performing the electrical testing, the sensing unit senses the electrical signal on the connected transmission line and transmits the electrical signal to the processing unit. The processing unit converts the electrical signal into a voltage signal and compares it with the preset threshold of the voltage signal. When the threshold is exceeded, it indicates that there is reverse power transmission in the transmission line. At this time, the automatic power-off circuit is turned on to disconnect the connection between the transmission line and the grounding device, thereby providing good protection for the operator. In addition, during the electrical testing process, the anti-interference circuit is activated to avoid electromagnetic interference with the electrical testing module and ensure the accuracy of the electrical testing.

[0043] In this embodiment, the automatic power-off circuit is the first layer of protection, and the second layer of protection is also provided by providing an alarm device 25. When the power test module 20 detects that the line is energized, the alarm device 25 gives an alarm in real time, so that the operator can be informed of the energized state of the line in time. Specifically, the alarm device 25 can be an indicator light 251, or a buzzer alarm 252, or both the indicator light 251 and the buzzer alarm 252 can be provided at the same time, so as to avoid the situation where one of the alarms fails and the other alarm can still alarm and remind the operator. Of course, the alarm device 25 is not limited to the indicator light 251 or the buzzer alarm 252 listed in this embodiment, and can also be an alarm device 25 of other types, such as a vibration alarm.

[0044] In this embodiment, the power test module 20 also includes a charging template (not shown in the figure), the charging module is electrically connected to the power module 21, and the operation panel 23 is also provided with a charging interface 26 electrically connected to the charging module. The charging interface 26 can more conveniently charge the power module 21 in the insulating rod 10, thereby better providing power supply for the power test module 20, avoiding the inconvenience of disassembly and installation caused by using dry batteries, etc. In this embodiment, since the power module 21 can provide power to the power test module 20 and can continuously test the power, it has a long-term power test function, and can still detect and judge the power status of the power transmission line or equipment after a long time interval, and issue an alarm in real time.

[0045] Furthermore, in other embodiments, the electrical testing module 20 also includes a wireless communication module, which can feed back the detection results of the electrical testing module 20 to the background monitoring terminal in real time, so that the background monitoring terminal can grasp the situation of the front work site in real time and make regulatory arrangements.

[0046] In this embodiment, a window corresponding to the size of the operation panel 23 is provided on the insulating rod 10, and the operation panel 23 protrudes from the outside of the insulating rod 10 through the window, so that when operating, the operation panel 23 can be touched, and the control switch 24 is a push-button switch, which has a better hand feel. Of course, the operation panel 23 can also be embedded in the window without protruding, and the control switch 24 can also be set as a sliding switch or a touch switch as needed.

[0047] In other embodiments, the above-mentioned power testing module 20 , power module 21 , operation panel 23 and alarm device 25 may also be integrated into a small control box, and the control box is disposed on the insulating rod 10 .

[0048] In this embodiment, the insulating rod 10 is a fixed single rod structure. In other embodiments, the insulating rod 10 can also be designed as a telescopic rod or a folding rod, which is convenient for on-site needs and storage. In addition, when the insulating rod 10 is a telescopic rod or a folding rod, a numerical scale can be set on each telescopic rod or folding rod to facilitate the control of the telescopic length of the insulating rod 10.

[0049] In this embodiment, the first end and the second end of the insulating rod 10 are connected to the wire hanging device and the external components through the quick-plug interface, respectively, which improves the installation efficiency and convenience. Specifically, the first end of the insulating rod 10 is detachably connected to the wire hanging device, and the other end of the insulating rod 10 can be extended to connect the external extension component or the fixed component. When in use, the insulating rod 10 is connected to the wire hanging device and the external component through the two quick-plug interfaces. After use, the wire hanging device and the external component can be quickly disassembled for easy storage and carrying.

[0050] Specifically, a fixing head 30 is provided at the first end of the insulating rod 10, and the above-mentioned wire hanging device is fixed on the fixing head 30, and the wire hanging device is connected to the fixing head 30 through a thread. The thread connection facilitates disassembly and assembly, and improves disassembly and assembly efficiency.

[0051] In this embodiment, the wire hanging device is a customized monkey head clamp 40 structure, which is provided with a threaded rod 42 for clamping the wire. The fixed head 30 has a first threaded hole (not shown in the figure), and the threaded rod 42 extends into and is fixed in the first threaded hole and contacts the electrical testing contact 22.

[0052] In other embodiments, a rotating snap-on plug-in structure may also be provided between the fixed head 30 and the wire hanging device. Specifically, for example, a snap-on interface may be provided on the side wall of the mounting hole of the fixed head 30, and a clearance position may be provided next to the snap-on interface. A joint may be provided at the other end of the threaded rod on the wire hanging device, and a snap-on may be provided on the joint. When the joint of the wire hanging device is inserted into the mounting hole of the fixed head 30, the snap-on is aligned with the clearance position and inserted. After the joint of the wire hanging device is in place, the joint of the wire hanging device is rotated so that the snap-on is inserted into the snap-on interface, thereby achieving a fixed connection between the fixed head 30 and the joint of the wire hanging device. When disassembling, the joint is rotated in the opposite direction so that the snap-on is withdrawn from the snap-on interface to the clearance position. At this time, the connecting end of the wire hanging device can be pulled out.

[0053] In other embodiments, the end of the threaded rod 42 close to the fixed head 30 can also be configured as a hanging ring, and the fixed head 30 can also be configured as a hook shape. The hook-shaped fixed head 30 and the hanging ring are detachably connected, and the fixed head 30 and the monkey head clamp 40 can also be quickly disassembled and assembled.

[0054] Reference Figure 2 In this embodiment, the monkey head clamp 40 includes a C-shaped monkey head clamp body 41, and a threaded rod 42 is movably arranged at the bottom end of the monkey head clamp body 41, that is, the threaded rod 42 is arranged along a direction perpendicular to the C-shaped opening of the monkey head clamp 40, and the end of the threaded rod 42 away from the fixed head 30 extends into the C-shaped opening, and a clamp 43 is arranged on this end. When the threaded rod 42 moves, the clamp 43 is driven to form a clamping opening between the top of the monkey head clamp body 41 for clamping or loosening the power transmission line. And because the threaded rod 42 is connected to the insulating rod 10 through the fixed head 30, the rotating insulating rod 10 can drive the threaded rod 42 to rotate, so that the threaded rod 42 drives the clamp 43 to approach or move away from the top of the monkey head clamp 40, thereby clamping or loosening the power transmission line.

[0055] Further, as a preferred solution, an elastic member (not shown in the figure) can be sleeved below the clamp 43 at one end of the threaded rod 42 close to the fixed head 30, or at one end of the threaded rod 42 extending into the monkey clamp body 41. Specifically, the elastic member is a spring. When the clamp 43 is away from the top of the monkey clamp body 41, the spring is in a compressed state, and a clamping opening is formed between the clamp 43 and the top of the monkey clamp body 41 to hang the power line. After the power line is hung, the spring is in a telescopic state, and its elasticity is used to better clamp the power line in the clamping opening between the clamp 43 and the top of the monkey clamp body 41.

[0056] In this embodiment, the chuck 43 includes a base 431 connected to the threaded rod 42 and a clamping rod 432 extending from the base 431. The clamping rod 432 is located at the four corners of the base 431, and the two sides of the base 431 opposite to the top of the monkey head clamp body 41 have arc-shaped notches, and the top of the monkey head clamp body 41 is bent into an arc shape corresponding to the two arc-shaped notches. Such an arc-shaped structure adapts to and matches the outer wall of the power transmission line, so that the power transmission line can be clamped and fixed between the chuck 43 and the top of the monkey head clamp body 41.

[0057] Furthermore, in order to better fix the power line and achieve a good conductive effect, a plurality of puncture needles (not shown in the figure) can be arranged on the base 431 of the clamp 43. When the clamp 43 and the top of the monkey head clamp body 41 clamp the power line, the puncture needle is inserted into the power line, which can not only better fix the power line, but also contact the battery cell of the power line to better conduct electricity. The puncture needle is sharp, and when the clamp 43 is retracted, the puncture needle is also retracted, which will not restrict the movement of the clamp 43.

[0058] In this embodiment, Figure 1 It can be seen that the side wall of the monkey head clamp body 41 is also provided with a connection device for the ground wire. Specifically, the connection device includes a connection block 44 provided on the side wall of the monkey head clamp body 41, two bolts (not shown in the figure) provided on the connection block 44, and two nuts 45 sleeved on the two bolts. In a common ground wire structure, one end of the ground wire has a ground wire connector (not shown in the figure), which is a copper sheet with two perforations. The copper sheet is sleeved on the two bolts through the two perforations, and then screwed on the bolts through two nuts 45 to lock the copper sheet, thereby achieving a fixed connection between the ground wire and the monkey head clamp 40.

[0059] In this embodiment, the connecting block 44 is fixed on the monkey head clamp 40, and the ground wire connector is fixed on the connecting block 44. Of course, the connection of the ground wire can also adopt other structures. For example, a movable structure similar to the clamp 43 can also be adopted, that is, the connecting block 44 is movably connected to the monkey head clamp body 41 by a bolt. The bolt is turned to drive the connecting block 44 to approach or move away from the monkey head clamp body 41, and a clamping opening for the ground wire to pass through is formed between the connecting block 44 and the monkey head clamp body 41. Specifically, in order to better fix the power transmission line, a notch matching the outer wall of the ground wire can also be provided on the side wall of the connecting block 44 and / or the monkey head clamp body 41. Similarly, in order to achieve a better clamping effect, a spring can also be provided on the bolt. When the clamping opening between the connecting block 44 and the monkey head clamp body 41 is relatively opened, the spring is in a compressed state. When the ground wire penetrates into the clamping opening, the ground wire is more firmly fixed by the elasticity of the spring and the locking effect of the bolt.

[0060] Furthermore, in order to achieve a better conductive effect between the ground wire and the main wire after being connected, in other embodiments, a copper wire (not shown in the figure) may be provided between the clamp 43 and the connecting block 44 as an attachment point for conducting electricity. Specifically, one end of the copper wire may be sleeved on the bolt of the connecting block 44 through a copper sheet and fixed by a nut, and the other end of the copper wire may be fixed to the clamp 43 by a screw or the like.

[0061] In other embodiments, a ring or a hook may be provided on the top of the monkey head clamp body 41 to facilitate connection with other tools, such as a shooting gun, a hook, etc.

[0062] In other embodiments, the monkey head clamp 40 may also have two monkey head clamp bodies 41 disposed back to back, that is, the monkey head clamp 40 has two clamping openings for threaded rods at the same time, so that two power transmission lines can be hung at the same time.

[0063] Regardless of the structure of the monkey head clip 40, the monkey head clip 40 can be made of cooked aluminum integral die-casting, which is beautiful and durable, and is corrosion-resistant and anti-oxidation, and can effectively prevent rust. Of course, the monkey head clip 40 can also be made of copper material as needed.

[0064] In this embodiment, the wire hanging device also includes a ground wire (not shown in the figure) and a grounding pin (not shown in the figure) connected to the ground wire. One end of the ground wire is fixed on the monkey head clamp body 41, and the other end of the ground wire is fixedly connected to the grounding pin.

[0065] Furthermore, the grounding pin is a T-shaped structure that is cold-galvanized, and a connecting plate for connecting to the ground wire is provided on the grounding pin. The connecting plate can also be used to engage in the matching structure of bolts and nuts to lock the grounding connector of the subway. Of course, a grounding pin with a straight-line structure can also be used, and a connecting hole is directly provided on the top of the straight-line structure, and the grounding connector of the ground wire is fixed at the connecting hole through a fastener.

[0066] The bottom of the grounding needle has a high-hardness conical needle tip, and a hose protective cover is provided on the high-hardness conical needle tip. When not in use, the hose protective cover is covered on the needle tip of the grounding needle to prevent the needle tip from piercing or injuring the operator or other parts, and also protect the grounding needle.

[0067] In this embodiment, the second end of the insulating rod 10 is further provided with a connection joint 50, and the external component is extended through the connection joint 50 to lengthen the insulating rod 10, or the insulating rod 10 is fixed through the connection joint 50. A second threaded hole (not shown in the figure) is provided in the connection joint 50, and the outer wall of the connection joint 50 also has an external thread (not shown in the figure). In this way, when lengthening or fixing the insulating rod 10, it can be selected to connect and fix through the second threaded hole or the external thread according to the actual situation on site. Of course, the connection joint 50 can also adopt other structures, that is, it can be adaptively designed according to the specific structure of the component to be extended.

[0068] Reference Figure 3 The insulating rod 10 is connected to an extension rod 60 through the connecting joint 30, so that it is more convenient to work on site. After the work is completed, the extension rod 60 can be disassembled using the connecting joint 30 for easy storage and carrying.

[0069] In this embodiment, when the grounding device with a long-term power test function is used, it performs power test while hanging the line, and can timely discover the reverse power transmission of the power transmission line, effectively avoiding the prior art of performing power test before hanging the line, and the possible equipment damage accident or operator safety accident caused by inaccurate power test or power test. At the same time, since the grounding device has its own power test module 20, there is no need to perform power test operation, which also saves the time of hanging the line, and significantly improves the safety and convenience of power operation.

[0070] Further, refer to Figure 4 This embodiment also provides a method for controlling the electric power detection using the above-mentioned grounding device with a long-term electric power detection function, the method comprising:

[0071] The positioning detection circuit detects whether the grounding device is located on the transmission line to be detected. Specifically, the positioning detection circuit mainly determines whether the grounding device is located on the transmission line to be detected by sensing whether the height of the grounding device is a preset height through a position sensor;

[0072] When the detection circuit detects that the grounding device is located on the transmission line, the sensing unit of the power detection module starts to sense the electrical signal on the transmission line;

[0073] The detected electrical signal is analyzed and compared by the processing unit. When the electrical signal reaches a set threshold, the processing unit sends a drive signal to the alarm device to sound an alarm. At the same time, the automatic power-off protection circuit is activated. Specifically, the electrical signal is a current signal, and the threshold can be directly a current threshold or a voltage threshold. When it is a current threshold, the processing unit directly compares, and when it is a voltage threshold, it is necessary to convert the current signal into a voltage signal for comparison.

[0074] When processing the signal to analyze and compare the electrical signal, the anti-interference circuit is activated.
