Description

Technical Field

[0001] This utility model relates to the field of high-voltage lines, specifically to a crossarm insulator for high-voltage lines. Background Technology

[0002] High-voltage lines typically refer to transmission lines that carry voltages of 10kV or higher. High-voltage lines require crossarm insulators during operation. As an important component of the power system, high-voltage line crossarm insulators are mainly used in overhead lines. They serve both to insulate the conductors from the ground and to act as crossarms. In high-voltage lines, crossarm insulators are mainly used to support the conductors and ensure that the conductors maintain sufficient insulation distance from the ground, towers, and other metal components to prevent current leakage and short-circuit accidents.

[0003] A search revealed a high-voltage line crossarm insulator with publication number CN215770705U, specifically disclosing a high-voltage line crossarm insulator, relating to the technical field of high-voltage transmission auxiliary devices. Addressing the problem that existing insulators cannot effectively resist vibration, the following solution is proposed: It includes a mounting plate and a connecting device fixedly connected to the mounting plate. A receiving cover is fixedly connected inside the connecting device. A guide pipe is fixedly connected to one side of the receiving cover, and a damping device is fixedly connected to the other end of the guide pipe. A ceramic insulating sleeve is sleeved on the outside of the damping device, and a contact tube is fixedly sleeved in the middle of the ceramic insulating sleeve. A limiting device, fixedly connected to the damping device, is connected to the contact tube. This utility model has a simple structure and is easy to use. It can convert the kinetic energy of the impact into internal energy. Simultaneously, through the buffering of multiple buffer parts, it can reduce the sway amplitude, protect the life of the device, and ensure the overall operation.

[0004] The existing high-voltage line crossarm insulators are cumbersome to install due to the different cable positions and angles in high-voltage lines, and the straight connection between the two ends of the crossarm insulators. This increases the time operators spend working at heights. In addition, the high-voltage line crossarm insulators in the aforementioned comparative cases also lack convenient means to adjust the installation angle and install quickly. This not only delays the overall installation and use efficiency in high-voltage lines in the long run, but also makes subsequent maintenance more complicated.

[0005] Therefore, it is necessary to invent a crossarm insulator for high-voltage lines to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high-voltage line crossarm insulator. Through a mounting base, adjusting groove, mounting bolts, damping shaft, adjusting frame, connecting hardware, first clamp, and second clamp, the installation method is not only quick and efficient but also allows for adjustment of the installation angle and position, ensuring the crossarm insulator aligns with the high-voltage line. This achieves rapid installation, reducing the time spent by operators working at heights. Furthermore, after the cable is connected, the second clamp can be pressed against the first clamp to secure the cable passing through the connecting hardware, ensuring the stability of the crossarm insulator on the high-voltage line. This addresses the problem in existing high-voltage line crossarm insulators where the straight-through connection method at both ends is cumbersome due to varying cable positions and angles, increasing the time spent by operators working at heights. Additionally, the aforementioned comparative cases also lack convenient methods for adjusting the installation angle and rapid installation, which, in the long run, not only delays the overall installation and use efficiency on high-voltage lines but also makes subsequent maintenance cumbersome.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crossarm insulator for high-voltage lines, comprising a crossarm insulating core rod, and a crossarm insulator body for use on high-voltage lines;

[0008] The mounting base is located at the bottom of the crossarm insulating core rod and is used for docking with the high-voltage line. An adjustment groove is provided on the top of the mounting base, and a reinforcing shim is provided above the adjustment groove. A mounting bolt passes through the top of the reinforcing shim.

[0009] A damping shaft is located at the top of the crossarm-type insulating core rod and is used to connect and install an adjustment frame. A connecting hardware is fixedly installed above the adjustment frame. A first wire clamp is provided inside the connecting hardware. A telescopic rod is fixedly installed at the bottom of the first wire clamp. A torsion spring is provided outside the telescopic rod. An abutment screw passes through the top of the connecting hardware. A second wire clamp is fixedly installed at one end of the abutment screw.

[0010] Preferably, an insulating and anti-fouling umbrella skirt is fixedly installed on the outside of the crossarm insulating core rod, an upper umbrella skirt cover is provided above the insulating and anti-fouling umbrella skirt, a double-headed insulating bolt passes through the upper umbrella skirt cover, and a lower umbrella skirt cover is movably connected to one end of the double-headed insulating bolt.

[0011] Preferably, the upper umbrella skirt and the lower umbrella skirt are threaded together, and the upper umbrella skirt is evenly distributed on the crossarm insulating core rod.

[0012] Preferably, a hexagonal nut is movably connected to the outside of the double-ended insulating bolt, and a fastening spring is provided on the outside of the double-ended insulating bolt.

[0013] Preferably, the mounting base is fixedly connected to the crossarm insulating core rod, and the connecting hardware is movably connected to the crossarm insulating core rod.

[0014] Preferably, the first clamp is movably connected to the connecting hardware, and the second clamp is threadedly connected to the connecting hardware.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model is equipped with a mounting base, an adjustment groove, mounting bolts, a damping shaft, an adjustment frame, connecting hardware, a first clamp, and a second clamp. When using this high-voltage line crossarm insulator, due to the different positions of the high-voltage line cables, the adjustment groove can be used to move the reinforcing shims and mounting bolts to adjust them to match the installation position of the line. This facilitates the connection of one end of the crossarm insulator to the high-voltage line cable first. Then, according to the installation requirements, the orientation of the connecting hardware can be adjusted through the damping shaft and the adjustment frame to make the crossarm insulator consistent with the high-voltage line cable before connection. This installation method is not only quick and efficient, but also allows for adjustment of the installation angle and position to ensure that the crossarm insulator is aligned with the high-voltage line, thus achieving the purpose of rapid installation and reducing the time spent by operators working at heights. At the same time, after the cable is connected, the contact screw can be twisted to squeeze the second clamp against the first clamp, thereby clamping and fixing the cable passing through the connecting hardware, thus ensuring the stability of the crossarm insulator on the high-voltage line.

[0017] 2. This utility model includes a crossarm-type insulating core rod, an insulating anti-pollution skirt, an upper skirt cover, a double-headed insulating bolt, a lower skirt cover, a hexagonal nut, and a fastening spring. When using this high-voltage line crossarm insulator, since the crossarm insulator is used outdoors for a long time, an upper and lower skirt cover can be installed on the outside of the insulating anti-pollution skirt using the double-headed insulating bolt. The fastening spring and hexagonal nut can adjust the tightness of the connection between the upper and lower skirt covers. This gives the insulating anti-pollution skirt a certain protective capability, reduces the damage to the insulating anti-pollution skirt caused by external factors, and also reduces the probability of large stains directly contacting the insulating anti-pollution skirt, ensuring the normal use of the high-voltage line crossarm insulator and reducing the risk of flashover.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The present invention is a crossarm insulator for high-voltage lines, comprising a crossarm insulating core rod 1 and a crossarm insulator body for use on high-voltage lines.

[0028] Mounting base 8 is located at the bottom of crossarm type insulating core rod 1 and is used for docking and installation with high voltage line. An adjustment groove 9 is provided above the mounting base 8, a reinforcing shim 10 is provided above the adjustment groove 9, and a mounting bolt 11 passes through the upper part of the reinforcing shim 10.

[0029] A damping shaft 12 is located at the top of the crossarm-type insulating core rod 1 and is used to connect and install an adjusting frame 13. A connecting hardware 14 is fixedly installed above the adjusting frame 13. A first wire clamp 15 is provided inside the connecting hardware 14. A telescopic rod 16 is fixedly installed at the bottom of the first wire clamp 15. A torsion spring 17 is provided outside the telescopic rod 16. An abutment screw 18 passes through the top of the connecting hardware 14. A second wire clamp 19 is fixedly installed at one end of the abutment screw 18. After the cable is connected, the abutment screw 18 can be twisted to squeeze the first wire clamp 15 through the second wire clamp 19, thereby clamping and fixing the cable passing through the connecting hardware 14, thus ensuring the stability of the crossarm-type insulator when used on high-voltage lines.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, an insulating and anti-pollution umbrella skirt 2 is fixedly installed on the outside of the crossarm insulating core rod 1. An upper umbrella skirt sleeve 3 is provided above the insulating and anti-pollution umbrella skirt 2. A double-headed insulating bolt 4 passes through the upper umbrella skirt sleeve 3. One end of the double-headed insulating bolt 4 is movably connected to a lower umbrella skirt sleeve 5. The upper umbrella skirt sleeve 3 and the lower umbrella skirt sleeve 5 can be installed on the outside of the insulating and anti-pollution umbrella skirt 2 through the double-headed insulating bolt 4. The upper umbrella skirt sleeve 3 and the lower umbrella skirt sleeve 5 are threadedly connected. The upper umbrella skirt sleeves 3 are evenly distributed on the crossarm insulating core rod 1. The upper umbrella skirt sleeves 3 and the lower umbrella skirt sleeve 5 give the insulating and anti-pollution umbrella skirt 2 a certain protective ability and reduce the damage to the insulating and anti-pollution umbrella skirt 2 caused by external factors. A hexagonal nut 6 is movably connected to the outside of the double-headed insulating bolt 4. A fastening spring 7 is provided on the outside of the double-headed insulating bolt 4. The fastening spring 7 and the hexagonal nut 6 can adjust the tightness of the connection between the upper umbrella skirt sleeve 3 and the lower umbrella skirt sleeve 5.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the mounting base 8 is fixedly connected to the crossarm insulating core rod 1, and the connecting hardware 14 is movably connected to the crossarm insulating core rod 1. Due to the different positions of the high-voltage line cables, the adjusting groove 9, the moving reinforcing shim 10 and the mounting bolt 11 can be adjusted to match the line installation position, so that one end of the crossarm insulator can be connected to the high-voltage line cable first. The first clamp 15 is movably connected to the connecting hardware 14, and the second clamp 19 is threadedly connected to the connecting hardware 14. The connecting hardware 14 has a simple structure and is easy to operate. If a fault occurs, it is convenient for maintenance personnel to replace it in time without delaying the normal use of the high-voltage line crossarm insulator.

[0032] The working principle of this practical application is as follows: First, when installing the crossarm insulator on a high-voltage line, remove the crossarm insulator. Then, using double-ended insulating bolts 4, install the upper skirt sleeve 3 and lower skirt sleeve 5 on the outside of the insulating anti-pollution skirt 2 for each skirt 2. Next, by turning the hexagonal nut 6 and pressing the fastening spring 7, the tightness of the connection between the upper and lower skirt sleeves 3 and 5 can be adjusted. This gives the insulating anti-pollution skirt 2 a certain level of protection, reducing damage caused by external factors and decreasing the probability of large stains directly contacting it. Then, depending on the location of the high-voltage line cable, the adjusting groove 9, the moving reinforcing shim 10, and the mounting bolts 11 can be adjusted to match the installation position of the line. This facilitates the connection of one end of the crossarm insulator to the high-voltage line cable, followed by installation according to requirements. The orientation of the connecting hardware 14 is adjusted by using the damping shaft 12 and the adjusting bracket 13 to align the crossarm insulator with the high-voltage line cable before connection. This installation method is not only quick and efficient but also allows for adjustment of the installation angle and position, achieving rapid installation. After the cable is connected, the contact screw 18 can be twisted to press the second clamp 19 against the first clamp 15, thereby clamping and fixing the cable passing through the connecting hardware 14, ensuring the stability of the crossarm insulator on the high-voltage line. After all installations are completed, the crossarm insulator can be used normally on the high-voltage line. Finally, after completing the installation and use of all high-voltage line crossarm insulators according to the above operations, routine maintenance of the device is required. This completes the usage process of the high-voltage line crossarm insulator.
