Abstract
Description
Technical Field
[0001] This invention relates to a surge arrester, and more particularly to an installation and testing structure for a surge arrester. Background Technology
[0002] A surge arrester is an electrical device that can release the energy of lightning or power system overvoltage, protecting electrical equipment from transient overvoltage damage, and interrupting follow current to prevent system grounding short circuits. It is usually connected in parallel with the protected equipment. Surge arresters can effectively protect electrical equipment. Once an abnormal voltage occurs, the surge arrester will activate and play a protective role. When the voltage value returns to normal, the surge arrester will quickly return to its original state to ensure normal power supply to the system.
[0003] With the development of infrastructure capabilities, electricity has been brought to almost all areas, including remote ones. Base stations can be built in sparsely populated mountainous areas to connect the network and electricity. When cables pass through relatively open areas, they and signal towers are easy targets for lightning strikes during thunderstorms because there are no tall buildings around. Therefore, it is necessary to install surge arresters on the poles of cables, signal towers, or relay cables to conduct the energy of lightning strikes to the ground, thereby protecting cables, signal towers, and various electrical components. Surge arresters are usually fixed on poles or signal towers using brackets.
[0004] However, existing surge arrester mounting brackets often prioritize stability, using multiple levels of rods and fasteners to secure the entire arrester. While this ensures stability, surge arresters require annual inspections before the rainy season to guarantee their normal performance and grounding capabilities. Operators at high altitudes face complex mounting brackets, making comprehensive testing difficult. Yet, without proper securing, cantilevered surge arresters cannot remain stable in open outdoor environments.
[0005] Therefore, the purpose of this case is to provide a structure that can better fix the surge arrester and facilitate the testing and inspection of the surge arrester installation. Summary of the Invention
[0006] This invention provides an installation and testing structure for surge arresters, which can effectively solve the above-mentioned problems.
[0007] This invention is implemented as follows:
[0008] An installation and testing structure for a surge arrester, locked to the mounting surface, includes:
[0009] Two crossbars extending in the plane of the mounting surface;
[0010] An outer connecting arm secured between the two crossarms;
[0011] Lightning arrester secured to the bottom crossbar;
[0012] A lateral fixing structure that is slidably disposed inside the two crossbeams and movably abuts against the middle section of the surge arrester;
[0013] The longitudinal frame forms a cross-shaped structure with the transverse frame, and the longitudinal frame has a locking structure that abuts against the side wall of the middle section of the surge arrester.
[0014] A directional testing frame is installed below the bottom crossbar, and the directional testing frame is in movable contact with the surge arrester;
[0015] A mobile testing frame is installed above the top crossbeam; the mobile testing frame is used to acquire information about surge arresters throughout the line.
[0016] As a further improvement, the lateral fixing structure includes a slide block that slides with the inner side of the crossbeam, a lead screw located above the slide block, a rotating motor locked below the slide block, a nut seat threaded onto the lead screw, and a positioning member locked onto the nut seat, the positioning member being engaged with the side wall of the surge arrester.
[0017] As a further improvement, the positioning element includes an L-shaped extension arm, a hinge shaft fixed on the extension arm, a cleaning seat welded to the hinge shaft, a micro motor disposed in the cleaning seat, a shaft disc sleeved on the output shaft of the micro motor, several bristles inserted into the shaft disc, and a torsion spring sleeved on the outside of the hinge shaft.
[0018] As a further improvement, the positive fixing structure includes a top fixing bracket that snaps onto the upper part of the surge arrester's middle section and a bottom fixing bracket that snaps onto the lower part of the surge arrester's middle section.
[0019] As a further improvement, the cross structure formed by the horizontal and vertical frames of the base plate has a mounting plate for accommodating the surge arrester at the top, and the directional detection frame is located at the bottom of the mounting plate at a position corresponding to the gap between the horizontal and vertical frames.
[0020] As a further improvement, the orientation detection frame includes a mounting base locked to the mounting plate, a steering motor disposed in the mounting base, a rotating shaft connected to the steering motor, a flip plate snapped onto the rotating shaft, and a plurality of probes disposed on the flip plate.
[0021] As a further improvement, the four flip plates fit together tightly when not in use to form a quadrangular pyramid structure.
[0022] As a further improvement, rain and snow sensors and wind sensors are installed on the cross frame and longitudinal frame, and the rain and snow sensors and wind sensors are electrically connected to the steering motor.
[0023] As a further improvement, the mobile inspection frame includes a guide rail welded to the top of the crossbeam, guide rails of adjacent crossbeams connected together, a mobile trolley slidably connected within the guide rail, and a camera locked onto the mobile trolley, the bottom of the camera not extending beyond the bottom of the guide rail.
[0024] As a further improvement, a plurality of delay pads are provided on the top of the inner side of the guide rail, the surface roughness of the delay pads is greater than that of the guide rail, and a piezoelectric sensor is provided on the inner side of the delay pads.
[0025] The beneficial effects of this invention are:
[0026] This invention integrates and fixes the surge arrester in the middle section using a lateral and forward fixing structure, thus stably securing the arrester. Simultaneously, a directional testing frame is installed at the bottom of the arrester, enabling testing at the fixed location. A mobile testing frame then allows for mobile testing of the arresters along the entire line. This entire solution achieves secure locking of the arresters while eliminating the need for maintenance personnel to climb to their locations for inspection. It allows for both directional testing at individual locations and mobile testing across the entire line, resulting in a more comprehensive testing process. Attached Figure Description

[0037] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0038] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0039] In open outdoor environments, where there are no other buildings, cable trays, poles, and signal towers located in open areas become targets for lightning strikes during thunderstorms. Therefore, installing surge arresters on cable support structures, installation structures, and relay structures is unavoidable. Existing methods for fixing surge arresters employ various complex structures to securely lock the entire arrester in place. However, while this ensures stability, it also increases the difficulty of maintenance. Maintenance personnel must navigate around these complex structures to perform repairs, requiring them to climb along the entire line, which poses a safety risk. Therefore, to address the aforementioned technical problems, this paper proposes the following technical solution:
[0040] Reference Figure 1-9As shown, an installation and testing structure for a surge arrester, locked onto a mounting surface, includes: two horizontal frames 1 extending within the plane of the mounting surface; an outer connecting arm 2 locked between the two horizontal frames 1; a surge arrester A locked onto the bottom horizontal frame 1; a lateral fixing structure 3 slidably disposed inside the two horizontal frames 1 and movably abutting against the middle section of the surge arrester A; a longitudinal frame 4 forming a cross shape with the horizontal frames 1, the longitudinal frame 4 having a positive fixing structure 41 locked onto the side wall of the middle section of the surge arrester A; a directional testing frame 5 disposed below the bottom horizontal frame 1, the directional testing frame 5 movably abutting against the surge arrester A; and a mobile testing frame 6 disposed above the top horizontal frame 1, the mobile testing frame 6 being used to acquire information about the surge arresters A throughout the entire line.
[0041] For example, in this embodiment, the entire surge arrester A is installed on a pole, such as a utility pole, and the entire crossbar 1 is fastened to the pole by clamps.
[0042] Subsequently, in order to improve the connection between the two crossbars 1, the two crossbars 1 need to be connected together by the outer connecting arm 2 through the screw and nut, so that the crossbars 1 are stable and the surge arrester A can be locked to the inner side of the lower crossbar 1, thus completing the initial fixation of the surge arrester A. However, at this time, the surge arrester A is prone to loosening under external forces, such as wind and rain.
[0043] Therefore, additional fixing structures are needed. In the existing technology, the arrester A is fixed at different positions, so that the arrester A is fixed in multiple positions. Although this improves the fixing effect, it does not leave any other space for maintenance personnel or other maintenance equipment, making maintenance extremely difficult before the rainy season.
[0044] In response to the above situation, this case adopts a centralized fixing method. Specifically, the entire fixing point is integrated into the middle section of surge arrester A. A cross-shaped fixing method is used, that is, a cross structure of horizontal frame 1 and vertical frame 4 is used. The lateral fixing structure 3 is fixed to the middle section of surge arrester A using the left and right lateral fixing structure 3. At the same time, the front and back front fixing structure 41 is fixed to the upper and lower ends of the middle section of surge arrester A using the front and back front front fixing structure 41. In total, a two-way four-point fixing method is used at the middle section of surge arrester A. The surge arrester A is integrated and fixed in the middle section area of surge arrester A. After the bottom fixing effect is removed, surge arrester A is fixed to its installation position by multiple positions such as the sides, top, and bottom. The internal structure will not be easily changed and its use effect will not be affected.
[0045] Since the fixed points and structures are integrated in the middle of the surge arrester A, a large amount of space is left at the top and bottom of the crossbeam 1 to facilitate operation or installation of other structures. In this embodiment, in order to reduce the labor intensity of construction workers and ensure construction safety, an unmanned operation method is adopted. A directional testing frame 5 is set at the bottom of each surge arrester A, which can perform timed and fixed-point testing at specific times or when specific situations occur. In addition, mobile testing frames 6 are laid on each crossbeam 1 along the entire line, and all mobile testing frames 6 are connected together to form a complete maintenance line. Fixed-point, fixed-line, and fixed-surface testing can be carried out during the rainy season each year, and a more comprehensive maintenance of the surge arrester A can be carried out. Workers do not need to climb the entire cable to inspect each surge arrester A one by one.
[0046] For different models of surge arresters A, due to differences in length and number of sections, the lateral fixing structure 3 may need to be moved to different positions. Corresponding to different positions of surge arrester A, to achieve adjustment of the position of the lateral fixing structure 3, the lateral fixing structure 3 includes a slide block 31 that slides into the inner side of the crossbeam 1, a lead screw 32 located above the slide block 31, a rotary motor 33 locked below the slide block 31, a nut seat 34 threaded onto the lead screw 32, and a positioning member 35 locked onto the nut seat 34. The positioning member 35 is engaged with the side wall of the surge arrester A. In use, the rotation of the rotary motor 33 can be controlled to rotate the lead screw 32, thereby... The position of the nut seat 34 on the lead screw 32 changes, resulting in a vertical position change. After the vertical position change, it is necessary to make the lateral fixing structure 3 fit and press against the surge arrester A to improve the cooperation force between the two. Therefore, after the vertical position adjustment, the slide 31 slides in the cross frame 1. The inner side of the cross frame 1 is a structure with C-shaped steel welded together at both ends. The slide 31 is a slider structure equipped with a linear motor. It can first move the lateral fixing structure 3 away from the surge arrester A through the slide 31 to complete the vertical position change, and then move it closer to the surge arrester A to achieve the horizontal position adjustment. It can fix the middle position according to the specifications of the surge arrester A.
[0047] Since surge arrester A is fixed in a relatively open outdoor location, birds like to perch on the cables and rest. Their droppings can easily cover the composite line insulation string in surge arrester A, affecting the detection equipment's judgment of surge arrester A. Therefore, in order to avoid a large amount of bird droppings on surge arrester A, it is necessary to install cleaning equipment to clean the insulation string. However, since a lateral fixing structure 3 is required, installing a cleaning structure would easily cause a positional conflict between the two.
[0048] Therefore, in this embodiment, the cleaning structure is hidden in the lateral fixing structure 3, which avoids spatial conflict between the two. The specific structure is as follows: the positioning member 35 includes an L-shaped extension arm 351, a hinge shaft 352 fixed on the extension arm 351, a cleaning seat 353 welded to the hinge shaft 352, a micro motor 354 disposed in the cleaning seat 353, a shaft disk 355 sleeved on the output shaft of the micro motor 354, and several bristles 356 inserted into the shaft disk 355. A torsion spring is sleeved on the outside of the hinge shaft 352. The positioning member 35 has two states: one is as a positioning structure, and the other is as... In the cleaning structure, when it is used as a positioning structure, the slide 31 moves towards the surge arrester A, so that the positioning member 35 is in a coiled state. At this time, the brush bristles 356 do not contact the insulating string of the surge arrester A. However, when it is used as a cleaning structure, the slide 31 moves away from the surge arrester A, and the torsion spring on the entire hinge shaft 352 is no longer under pressure. The cleaning seat 353 pops out, so that the brush bristles 356 contact the insulating string of the surge arrester A. The brush bristles 356 are rotated by the micro motor 354 driving the shaft disk 355 to perform cleaning. Due to the cooperation between the nut seat 34 and the lead screw 32, the brush bristles 356 can clean all parts of the outside of the surge arrester A.
[0049] In this embodiment, the cleaning seat 353 is set horizontally. However, in reality, the tilt position and length of the cleaning seat 353 can be changed according to the tilt angle and arrangement spacing of the insulation string to adapt to different specifications of surge arresters A.
[0050] In actual use, the extension arm 351 is made of wood or rubber, which can isolate the conductive relationship between the metal nut seat 34 and the hinge shaft 352. Even if the nut seat 34 is electrified, it cannot damage the structure of the micro motor 354.
[0051] After the lateral fixation is completed, the front-to-back fixation is required. In order to integrate the fixation points into the same point, the forward fixation structure 41 includes a top fixing bracket 411 that is snapped onto the upper part of the middle section of the surge arrester A, and a bottom fixing bracket 412 that is snapped onto the lower part of the middle section of the surge arrester A. This ensures that the two sides, top side, and bottom side of the middle section of the surge arrester A are all under pressure and are firmly fixed, while leaving space at the upper and lower ends of the surge arrester A.
[0052] As described above, a cross-shaped structure is formed between the horizontal frame 1 and the vertical frame 4. In order to improve the stability of the surge arrester A, the top of the cross-shaped structure formed by the horizontal frame 1 and the vertical frame 4 of the base plate is locked with a mounting plate B for placing the surge arrester A. However, the cross-shaped structure makes it difficult to set up the directional detection frame 5. Therefore, in this embodiment, the directional detection frame 5 is set at the bottom of the mounting plate B at the position corresponding to the gap between the horizontal frame 1 and the vertical frame 4, so that the directional detection frame 5 can be flipped to the position of the surge arrester A for detection.
[0053] Therefore, the directional testing frame 5 needs to be flipped. The directional testing frame 5 includes a mounting base 51 locked to the mounting plate B, a steering motor 52 set in the mounting base 51, a rotating shaft 53 connected to the steering motor 52, and a flipping plate 54 snapped onto the rotating shaft 53. The flipping plate 54 is provided with several probes 55, and each probe 55 has multiple pressure contacts. During the specific testing stage, the steering motor 52 drives the rotating shaft 53 to rotate, and the rotating shaft 53 causes the flipping plate 54 to rotate, causing all the probes 55 on the flipping plate 54 to rotate. After rotating, the probes 55 are attached to various positions of the surge arrester A to detect whether there is any damage or displacement on the outer surface of the surge arrester A. If one of the probes 55 does not detect a signal, it indicates that the surge arrester A has a local displacement phenomenon. At this time, it is necessary to mark it and conduct accurate testing by manual or other testing methods to ensure that all surge arresters A can be used normally before the rainy season.
[0054] During non-detection phases, to prevent damage to the flip plates 54 and the probes 55 on them, the four flip plates 54 are tightly fitted together to form a four-sided pyramid structure when not in use, with the tips of the pyramids pointing towards the ground. The flip plates 54 are retracted as much as possible to avoid damage. When the flip plates 54 are retracted, the steering motor 52 is locked, so they will not flip downwards due to gravity. The four-sided pyramid structure also provides a certain degree of support.
[0055] The steering motor 52 can be triggered in two ways. First, it can be remotely triggered, meaning the operator can periodically activate the steering motor 52 during two time periods each month, with each period approximately 15 days apart. The probe 55 will then periodically perform directional detection on the surge arrester A. Alternatively, a passive detection method can be used. Specifically, rain and snow sensors and wind sensors are installed on the crossbeam 1 and longitudinal frame 4. These sensors are electrically connected to the steering motor 52. Strong winds, rain, or snow can damage the surge arrester A. Therefore, when the rain and snow sensors detect a specific signal and send it to the terminal, the operator can immediately activate the steering motor 52 after the current extreme weather event ends. A safety check should be performed after each extreme weather event to ensure usability in the next extreme weather event.
[0056] After the aforementioned directional testing, the main focus is on checking whether the entire surge arrester A has shifted or significantly deviated. However, in reality, it's impossible to perform a more detailed test or determine the details of local locations. Therefore, to further improve the testing accuracy, a mobile testing frame 6 is installed above the surge arrester A. However, compared to the directional testing frame 5, the mobile testing frame 6 is more expensive to install, so it's not feasible to install one at each surge arrester A location. Therefore, the mobile testing frame 6 includes a guide rail 61 welded to the top of the crossbeam 1, with the guide rails 61 of adjacent crossbeams 1 connected. For example, if the entire cable spans ten kilometers and a total of ten surge arresters A are installed, then the mobile testing frame 6 needs to be... The system pauses ten times. It also includes a mobile cart 62 slidably connected within the guide rail 61, and a camera 63 locked to the mobile cart 62. The bottom of the camera 63 is not longer than the bottom of the guide rail 61. The mobile detection frame 6 mainly moves via the mobile cart 62. The camera 63 is used to obtain the specific situation of the surge arrester A and the cable. The camera 63 records the situation on the entire cable. It should be emphasized that the mobile cart 62 and the camera 63 are completely included in the guide rail 61. They will not be disturbed by external forces during the sliding process, ensuring stable movement. Furthermore, both the mobile cart 62 and the camera 63 face downwards, and their tops are protected by the guide rail 61.
[0057] During the entire movement of the mobile vehicle 62 and camera 63, most of the time is spent recording the cable, and only a small portion of the time is spent recording the surge arrester A. However, in order to ensure complete acquisition of information about the surge arrester A, several delay pads 611 are provided on the top of the inner side of the guide rail 61. The surface roughness of the delay pads 611 is greater than that of the guide rail 61. A piezoelectric sensor 612 is provided on the inner side of the delay pads 611. When the mobile vehicle 62 moves at a speed of 15 km / h, when it moves to the position of the delay pads 611, its speed will decrease significantly due to the roughness of the delay pads 611, which can increase the time for acquiring surface information of the surge arrester A, thus enabling more complete acquisition of surface information of the surge arrester A.
[0058] Furthermore, the camera 63 is actually an omnidirectional camera. The specific factor for its reversal is that when the mobile vehicle 62 moves to the position of the delay pad 611, it will simultaneously press on the piezoelectric sensor 612, causing the piezoelectric sensor 612 to cause the reversal structure of the camera 63 to rotate 45°, which can obtain information from the 45° direction of the surge arrester A. The delay pad 611 is provided in three sets, namely the direction facing the surge arrester A and the two 45° angle directions of the upper half of the surge arrester A. Therefore, surface information of the surge arrester A from different perspectives can be obtained from three directions. Moreover, compared with other areas on the cable, the dwell time is longer, the information obtained is clearer, and the burden on the operator when viewing is reduced.
[0059] The steering structure of the camera 63 and the signal flow between it and the piezoelectric sensor 612 are existing technologies and will not be described in detail here.
[0060] By using the bottom directional testing frame 5 and the top mobile testing frame 6, the position information of the entire surface of surge arrester A can be obtained. If there is no major damage, displacement or deformation on the surface of surge arrester A, the possibility of damage to its internal structure is also low. Therefore, based on the information obtained, the operator can determine that a small number of surge arresters A need to be inspected, while other surge arresters A that are not in problem can be ignored, reducing the workload while ensuring the normal operation of the entire cable.
[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
