In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0033] In this embodiment, if Figures 1 to 3 As shown, the pressurized wire fixing device is used to fix the pressurized wire 70 of the lightning arrester 50. The pressurized wire fixing device includes: an insulating vertical rod 10 and an insulating horizontal rod. The axis of the insulating vertical rod 10 is set at an angle to the vertical direction, the first end of the insulating vertical rod 10 overlaps the upper end of the lightning arrester 50, and the second end of the insulating vertical rod 10 contacts the ground. The first end of the insulating horizontal rod is adjustably connected to the first end of the insulating vertical rod 10, and the pressurized wire 70 is fixedly connected to the second end of the insulating horizontal rod.

[0034] In this way, the insulating vertical rod 10 is tilted and overlapped on the lightning arrester 50, which is simple and convenient to install, and the use of a base is avoided, reducing the volume and weight of the pressurized line fixing device. The insulating cross bar is connected to the insulating vertical rod 10, so that the pressurized line 70 led out of the connecting end of the lightning arrester 50 can be connected to the second end of the insulating cross bar, and because the position of the insulating cross bar on the insulating vertical rod 10 is adjustable, the insulating cross bar can adjust the height of the second end of the insulating cross bar according to the height of the pressurized line 70, so that the pressurized line 70 can be better horizontally led out. In addition, since the insulating cross bar is connected to the insulating vertical rod 10, the use of a base is avoided, the volume and weight of the pressurized line fixing device are reduced, and it is easy to carry and operate. Therefore, the technical solution of this embodiment effectively solves the problem that the pressurized line fixing device in the related art is large in volume and heavy in weight, and it is troublesome to carry. At the same time, due to the reduction in volume and weight, the operator can operate more easily during use, improving work efficiency and safety. This design significantly reduces the space occupation of the device, allowing the operator to easily put it into a tool box or a transport vehicle, greatly improving the portability of the device. Especially when maintaining power facilities in mountainous or remote areas, this lightweight feature allows operators to carry it to the work site more easily, reducing logistics costs and manpower burden.

[0035] like Figures 1 to 5As shown, the insulating cross bar includes a rod body 21 and a clamping member 22 arranged on the first end of the rod body 21, and the clamping member 22 can clamp the insulating vertical rod 10. The design of the clamping member 22 makes the connection between the insulating cross bar and the insulating vertical rod 10 more stable, and also facilitates the disassembly and assembly of the insulating cross bar and the insulating vertical rod 10, thereby improving the operating efficiency. In the maintenance and testing process of the power system, this feature of rapid disassembly and assembly can save a lot of time, especially in the occasion where the equipment needs to be frequently moved. The clamping member 22 includes a first swing arm 221 and a second swing arm 222 arranged opposite to each other, and a clamping member 223 penetrated on the first swing arm 221 and the second swing arm 222, and the clamping member 223 has a clamping position that makes the first swing arm 222 approach each other to clamp the insulating vertical rod 10 and a loosening position that makes the first swing arm 221 and the second swing arm 222 move away from each other to loosen the insulating vertical rod 10. The structure of the clamping member 22 is simple, easy to process and assemble, and convenient to use.

[0036] like Figures 1 to 5 As shown, the clamping member 223 is a bolt, a first threaded hole is provided on the first swing arm 221, and a second threaded hole is provided on the second swing arm 222, and the bolt is inserted into the first threaded hole and the second threaded hole. The first threaded hole and the second threaded hole have opposite rotation directions, and the bolt rotates to drive the first swing arm 221 and the second swing arm 222 to move closer to each other or away from each other. By designing that the first threaded hole and the second threaded hole have opposite rotation directions, it can be ensured that when tightening the bolt, the first swing arm 221 and the second swing arm 222 can move toward the center at the same time, so as to clamp the insulating vertical rod 10 more evenly, thereby ensuring the stability and reliability of the connection. It can also be ensured that when loosening the bolt, the first swing arm 221 and the second swing arm 222 can move outward at the same time, so as to loosen the insulating vertical rod 10 more quickly. The design that the first threaded hole and the second threaded hole have opposite rotation directions makes the operation more convenient and improves the work efficiency.

[0037] like Figures 1 to 5As shown, the clamping member 22 also includes a first clamping flap 224 disposed on the swing end of the first swing arm 221 and a second clamping flap 225 disposed on the swing end of the second swing arm 222. The first clamping flap 224 is provided with a first accommodating notch 226 opened toward the second clamping flap 225, and the second clamping flap 225 is provided with a second accommodating notch 227 opened toward the first clamping flap 224. When the first swing arm 221 and the second swing arm 222 clamp the insulating vertical rod 10, the insulating vertical rod 10 is located in the first accommodating notch 226 and the second accommodating notch 227. Such a design of the first clamping flap 224, the second clamping flap 225, the first accommodating notch 226 and the second accommodating notch 227 can further enhance the stability of clamping, prevent the relative sliding between the insulating cross bar and the insulating vertical rod 10 caused by external force during use, and improve the reliability of the entire device. Moreover, due to the setting of the first accommodating notch 226 and the second accommodating notch 227, the notch shape between the first swing arm 221 and the second swing arm 222 can be more adapted to the outer surface of the insulating vertical rod 10, thereby making the first swing arm 221 and the second swing arm 222 clamp the insulating vertical rod 10 more reliable.

[0038] like Figures 1 to 5 As shown, the insulating cross bar includes a rod body 21, a clamping member 22 arranged on the first end of the rod body 21, and a connecting member 23 connecting the rod body 21 and the clamping member 22. The rod body 21 is provided with a first deformation notch 211 extending along the axial direction of the rod body 21, and the first deformation notch 211 penetrates the end surface of the first end of the rod body 21. The clamping member 22 extends into the first end of the rod body 21, and the connecting member 23 is arranged outside the first end of the rod body 21 and has a fixed state of fixing the clamping member 22 to the first end of the rod body 21 and a separated state of enabling the clamping member 22 to be separated from the first end of the rod body 21. The design of the first deformation notch 211 and the connecting member 23 enables the clamping member 22 to be firmly fixed on the rod body 21, and at the same time, when disassembly is required, the clamping member 22 can be easily separated from the rod body 21 by changing the state of the connecting member 23, which is convenient for the maintenance of the device and replacement of components. In the daily maintenance of the power system, this design can greatly reduce the maintenance time and cost and improve the availability of the equipment. The first deformation notch 211 and the clamping member 22 have simple structures and are easy to install and use.

[0039] like Figures 1 to 5 As shown, the diameter of the connecting member 23 is adjustable. When the diameter of the connecting member 23 decreases, the first deformation notch 211 is deformed, and the clamping member 22 is fixed in the first end of the rod body 21. By adjusting the diameter of the connecting member 23, the shape of the first deformation notch 211 can be changed, thereby achieving the fixing and release of the clamping member 22. This design not only simplifies the structure of the device, but also improves the convenience of operation, and is particularly suitable for occasions that require rapid adjustment.

[0040] like Figures 1 to 5 As shown, the insulating cross bar includes a rod body 21 and a fixing member 24 disposed on the second end of the rod body 21, and the fixing member 24 includes a fixing seat 241 and a first fixing ring 243 disposed outside the fixing seat 241. The diameter of the first fixing ring 243 is adjustable, and the first fixing ring 243 has a first clamping state in which the diameter is reduced and a first releasing state in which the diameter is increased. When the first fixing ring 243 is in the first clamping state, the pressurized wire 70 is fixed between the fixing seat 241 and the first fixing ring 243. When the first fixing ring 243 is in the first releasing state, the pressurized wire 70 can be taken out from between the fixing seat 241 and the first fixing ring 243. The setting of the first fixing ring 243 can fix the pressurized wire 70 between the fixing seat 241 and the first fixing ring 243, or take the pressurized wire 70 out from between the fixing seat 241 and the first fixing ring 243 by adjusting the diameter of the first fixing ring 243. The structure of the first fixing ring 243 is simple, and it is easy to process and install.

[0041] In this embodiment, the pressurized wire fixing device also includes a nylon strap or Velcro 60 arranged between the clamping member 22 and the fixing member 24. The nylon strap or Velcro 60 can better connect the pressurized wire 70 to the insulating cross bar so that the pressurized wire 70 can be led out horizontally more horizontally and stably.

[0042] like Figures 1 to 5 As shown, a limiting notch 242 is provided on the fixing seat 241, and when the first fixing ring 243 is in the first clamping state, the pressurized line 70 is located in the limiting notch 242. The design of the limiting notch 242 can prevent the pressurized line 70 from sliding between the fixing seat 241 and the first fixing ring 243, ensuring that the fixed position of the pressurized line 70 is accurate, thereby improving the accuracy and safety of the test. When performing a high-voltage test on the lightning arrester 50, this design can prevent test errors or safety risks caused by the position deviation of the pressurized line 70. The setting of the limiting notch 242 greatly reduces the measurement error caused by the sliding of the pressurized line 70, thereby improving the accuracy of the test of the power equipment.

[0043] like Figures 1 to 5As shown, the rod body 21 is provided with a second deformation notch 212 extending along the axial direction of the rod body 21, and the second deformation notch 212 penetrates the end surface of the second end of the rod body 21. The fixing member 24 also includes a second fixing ring 244 arranged outside the second end of the rod body 21, and the fixing seat 241 is connected to the second fixing ring 244. The diameter of the second fixing ring 244 is adjustable, and the second fixing ring 244 has a second clamping state with a reduced diameter and a second release state with an increased diameter. When the second fixing ring 244 is in the second clamping state, the second deformation notch 212 is deformed, and the second fixing ring 244 fixes the fixing seat 241 on the rod body 21. When the second fixing ring 244 is in the second release state, the second fixing ring 244 can be separated from the rod body 21. The design of the second fixing ring 244 and the second deformation notch 212 further enhances the connection stability between the fixing member 24 and the rod body 21. At the same time, when disassembly is required, by adjusting the diameter of the second fixing ring 244, the fixing member 24 can be easily separated from the rod body 21, which is convenient for maintenance and component replacement of the device. The second deformation notch 212 and the second fixing ring 244 have simple structures, are easy to assemble and use, and improve work efficiency.

[0044] In this embodiment, the connecting member 23, the first fixing ring 243 and the second fixing ring 244 are preferably cable ties or elastically adjustable clamps.

[0045] like Figures 1 to 5 As shown, the pressurized line fixing device also includes an insulating flexible member 30 and a fixing buckle 40 arranged on the second end of the insulating cross bar. The fixing buckle 40 is fixed to the rod body 21 through a second fixing ring 244, and the first end of the insulating flexible member 30 is connected to the fixing buckle 40. The second end of the insulating flexible member 30 is connected to the ground, and the second end of the insulating flexible member 30 is spaced apart from the second end of the insulating vertical rod 10. The setting of the insulating flexible member 30 can reduce the swing of the insulating cross bar centered on the axis of the insulating vertical rod 10, prevent the device from tipping over or moving due to wind or external force during use, and improve the safety and reliability of the entire device. In outdoor operations of the power system, especially under high wind speed or complex terrain conditions, this design can effectively prevent the unstable state of the device, ensure the smooth progress of the test and the safety of the operator. The insulating flexible member 30 can ensure the stable fixation of the device and prevent accidental tipping or movement.

[0046] The inventor found that the arrester 50 DC 1mA reference voltage U 1mA and 0.75U 1mALeakage current is an important reference data for judging the performance of metal oxide arresters 50. For arresters 50 with a DC reference voltage U1mA greater than 66kV, there is a serious ionization current between the high-voltage lead and the base flange of the arrester 50. This interference current often causes the 0.75U1mA leakage current to fail to meet the program requirements, seriously affecting the health status judgment of the arrester 50. Therefore, the DC test of the arrester 50 requires that the pressurized line 70 be horizontally connected to reduce the leakage current. The height of the 500kV arrester 50 is relatively high, and the seat body that fixes the insulating rod also needs to be larger and heavier, otherwise the insulating rod is easy to topple over and the safety performance is low.

[0047] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0048] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0049] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
