Description

[0001] The present application relates to the technical field of power equipment maintenance, and in particular to a ground wire hanging auxiliary device and a ground wire hanging system. Background Art
[0002] The main function of the grounding wire is to conduct the residual charge in the power-off equipment and the line, and reduce the harm caused by the line being electrified due to lightning strikes in the distance, misoperation, line induction electrification, reverse power transmission of equipment, etc. during the maintenance process. When repairing power equipment, it is necessary to hang a temporary grounding wire to ensure the personal safety of the staff. A complete temporary grounding wire consists of a grounding head, a short-circuit grounding cable and a grounding hook. When hanging, the grounding hook needs to be hung on the three-phase line respectively. However, in some substations, since the main transformer is installed indoors, its three-phase line mainly enters and exits from the roof, which makes the setting height of the three-phase line relatively high, and then a longer short-circuit grounding cable is required to realize the temporary grounding operation of the three-phase line. The longer short-circuit grounding cable will cause the overall weight of the grounding wire to be very heavy. The existing technology mainly uses the insulated operating rod to manually control the grounding hook to the corresponding three-phase line. In addition, the indoor space is narrow, which makes it very difficult for the staff to hang the grounding wire, and it often takes a lot of time to hang the grounding wire. Utility Model Content

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0023] In one embodiment, Figure 1 As shown, the embodiment of the present application provides a ground wire hooking auxiliary device 100, which may specifically include a control box 110 and a lifting buckle 121 assembly 120, wherein the lifting buckle 121 assembly 120 may specifically include at least one buckle 121 for fixing the ground wire and a power mechanism for driving at least one buckle 121 to lift and lower, so as to lift the ground wire to a predetermined height. The control box 110 may specifically be electrically connected to the power mechanism to control the power mechanism to work.
[0024] It can be understood that the ground wire hanging auxiliary device 100 mentioned in the embodiment of the present application can be used in a substation, so that when the power equipment is repaired, the ground wire hanging operation of the three-phase line of the corresponding power equipment can be completed with the assistance of the ground wire hanging auxiliary device 100. The ground wire is generally composed of a ground wire head, a short-circuit grounding cable and a ground wire hook. In order to realize the ground wire hanging operation of the three-phase line of the corresponding power equipment, the ground wire hook of the corresponding ground wire needs to be hung at the corresponding position of the three-phase line, that is, the buckle 121 needs to drive the ground wire hook of the corresponding ground wire to perform synchronous lifting and lowering movement. Therefore, the buckle 121 needs to be compatible with the ground wire hook to realize the clamping operation of the corresponding ground wire hook. At the same time, in order to enable the buckle 121 to drive the ground wire hook of the corresponding ground wire to rise synchronously to the same or close height as the three-phase line, the maximum rising height of at least one buckle 121 driven by its power mechanism should be greater than or equal to the highest height above the ground of the three-phase line.
[0025] In this way, the ground wire hanging auxiliary device 100 of the embodiment of the present application can first clamp the ground wire hook of the ground wire through the buckle 121 when hanging the ground wire, and then control the power mechanism through the control box 110 to drive the buckle 121 to rise, and then drive the buckle 121 to raise the ground wire hook of the corresponding ground wire to a predetermined height (specifically, it can be a height close to the three-phase line to be hung). Then, the ground wire hook of the corresponding ground wire can be directly hung to the corresponding position of the three-phase line to be hung by manually operating the insulating operating rod. The entire ground wire hanging process can save a lot of time and physical effort because the lifting buckle 121 assembly 120 automatically lifts the heavy ground wire 200.
[0026] In some examples, such as Figure 1 As shown, the power mechanism can be specifically arranged adjacent to the three-phase line to be mounted, and the height of the power mechanism from the ground is greater than or equal to the highest height of the three-phase line to be mounted from the ground. The power mechanism can specifically include a motor power module 122 and at least one winch mechanism 123 drivingly connected to the motor power module 122, at least one winch mechanism 123 is arranged in a one-to-one correspondence with at least one buckle 121, the winch mechanism 123 includes an insulating rope 1231 and a winch 1232, one end of the insulating rope 1231 is fastened with a corresponding buckle 121, and the other end of the insulating rope 1231 is wound around the winch 1232, so that when the motor power module 122 drives the winch 1232 to rotate, the insulating rope 1231 is rolled up or unrolled by the winch 1232 to achieve the lifting operation of the corresponding buckle 121. In this way, the above-mentioned structure can be set so that each buckle 121 can be freely switched between the position adjacent to the ground and the position adjacent to the three-phase line to be connected under the action of the corresponding winch mechanism 123, so as to assist the staff to complete the connection operation of the corresponding grounding line. Further, the motor power module 122 can specifically include a power motor 1221 and a transmission 1222, and the motor shaft of the power motor 1221 is connected to the transmission 1222 through a coupling to drive the output shaft of the transmission 1222 to rotate, and the winch 1232 of each winch mechanism 123 is sleeved and fixed on the output shaft of the transmission 1222 to rotate synchronously with the output shaft of the transmission 1222. In this way, the above-mentioned structure can be set so that the high-speed rotation of the power motor 1221 can be converted into low-speed high-torque rotation through the conversion of the transmission 1222, and then the winch 1232 of each winch mechanism 123 on the output shaft can be better driven to rotate.
[0027] In some examples, such as Figure 1As shown, the control box 110 can be specifically arranged near the ground, and the control box 110 is electrically connected to the power mechanism by wire or wirelessly. In this way, through the above-mentioned structural arrangement, it is convenient for the staff to operate the control box 110 at any time. Furthermore, since the three-phase line needs to be connected to three grounding wires at the same time, the lifting buckle 121 assembly 120 in this example can specifically include three buckles 121, and each buckle 121 is driven by a winch mechanism 123. In this way, the three buckles 121 can simultaneously complete the synchronous rising operation of the ground wire hooks of the three grounding wires, so as to further save the hanging time.
[0028] In one embodiment, Figure 2 As shown, an embodiment of the present application provides a ground wire hanging system 1, which may specifically include the ground wire hanging auxiliary device 100 of the above embodiment and three grounding wires 200, each grounding wire 200 includes a ground wire head 210, a short-circuit grounding cable 220 and a ground wire hook 230, one end of the short-circuit grounding cable 220 is electrically connected to the ground wire hook 230, and the other end of the short-circuit grounding cable 220 is electrically connected to the ground wire head 210, and is electrically connected to the ground wire pile through the ground wire head 210.
[0029] It can be understood that the ground wire hooking system 1 mentioned in the embodiment of the present application can be used in a substation, so that when the power equipment is repaired, the ground wire hooking operation of the three-phase line of the corresponding power equipment is completed through the ground wire hooking system 1. The ground wire hooking auxiliary device 100 in this embodiment is completely the same in structure and function as the ground wire hooking auxiliary device 100 mentioned in the previous embodiment, and will not be repeated here.
[0030] In this way, the local wire hanging system 1 has the same functions and technical effects as the local wire hanging auxiliary device 100 mentioned in the previous embodiment, which will not be described in detail here.
[0031] In some examples, such as Figure 2 As shown, the ground wire hooking system 1 specifically also includes a computer key 300. At this time, the control box 110 specifically includes a control box body, a controller, and a lock 111 with a wireless code chip. The controller is built into the control box body, and the control box 110 is electrically connected to the power mechanism. The lock 111 is installed on the control box body, so that when the wireless code chip is successfully paired with the computer key 300, the control box body is opened to expose the controller. In this way, the safety performance of the control box 110 can be improved through the above-mentioned structural setting, that is, only when the staff holds the corresponding computer key 300 and opens the lock 111, can the controller be operated to perform the corresponding ground wire hooking operation.
[0032] In some examples, such as Figure 1As shown, the ground wire hooking system 1 specifically further includes a management host 400, and the ground wire hook 230 specifically includes a hook body and a ground wire hooking state detection module installed on the hook body, and the ground wire hooking state detection module is wirelessly connected to the management host 400. In this way, by setting the ground wire hooking state detection module, it is convenient for the staff to timely know the hooking state of the current ground wire 200 through the management host 400, so that the staff can timely adjust the hooking of the current ground wire 200.
[0033] It is understandable that the ground wire hooking state detection module may specifically include a micro switch and a path detection sensor, wherein the micro switch can be triggered only when the ground wire hook 230 of the current ground wire 200 is correctly hooked to the corresponding position of the three-phase line, so as to send a signal of successful physical hooking to the management host 400. The path detection sensor can be triggered only when the ground wire hook 230 of the current ground wire 200 is correctly hooked to the corresponding position of the three-phase line to form a corresponding ground loop, so as to send a signal of successful circuit hooking to the management host 400. The ground wire hooking state detection module may also specifically have a WAPI communication function, so as to wirelessly connect with the management host 400 through the WAPI base station 500.
[0034] In some examples, such as Figure 1 As shown, the ground wire hooking system 1 further includes an anti-misconnection adapter 600 and an electric detector 700. The anti-misconnection adapter 600 is wirelessly connected to the management host 400 and the computer key 300, respectively, and the electric detector 700 is wirelessly connected to the computer key 300. It can be understood that the wireless communication connection between the anti-misconnection adapter 600 and the management host 400 and the computer key 300, and the wireless communication connection between the electric detector 700 and the computer key 300 can be realized by Bluetooth or other wireless communication connection methods.
[0035] Thus, through the above-mentioned structural setting, when the staff performs the hooking operation of the grounding wire 200 , they can first send the operation sequence to the anti-mistake adapter 600 through the management host 400 , and the anti-mistake adapter 600 then sends the operation sequence to the computer key 300 . At this time, the staff can first use the computer key 300 to complete the disconnection of the circuit breaker switch and the opening of the isolating knife switch related to the main transformer line, that is, to realize the power-off operation of the three-phase line to be connected. Then, the electric tester 700 can be used to test the power of the three-phase line to be connected. If there is power, the electric tester 700 will sound and light alarm, and the discharge rod needs to be used to discharge the three-phase line to be connected before testing the power; if it is found that there is no power, the electric tester 700 will send the power-free information to the computer key 300, and the computer key 300 will obtain the authority to operate the next step. At this time, the computer key 300 can unlock the lock 111 of the control box 110. In this way, the use of the ground wire hanging auxiliary device 100 can be included in the anti-error system, and associated with the power test result to prevent the harm caused by the arbitrary hanging of the ground wire 200. Further, the ground wire hanging system 1 also includes a discharge rod for discharging the three-phase line to be connected.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
