[0032] S3, push up and rotate the self-locking positioning plate so that the bayonet is separated from the positioning block, and when the positioning ear is against the limiting column, the rotation of the self-locking positioning plate is stopped;

[0033] S4. The operator uses the pole climbing tool to climb to a certain height of the pole, and then puts on insulating gloves;

[0034] S5. The operator vertically inserts the lower ends of the first vertical plate and the second vertical plate into the rectangular sleeve, and ensures that the rectangular sleeve can stably hold the first vertical plate and the second vertical plate;

[0035] S6. Use a lifting sleeve to slowly lift the main body assembly with the built-in series gap arrester to the vicinity of the insulator on which the built-in series gap arrester is to be installed, and then adjust the orientation of the main body assembly so that the opening of the first U-shaped groove is opposite to the root of the corresponding insulator, the first horizontal plate is located above the horizontal plate of the cross arm supporting the insulator, and the horizontal plate of the cross arm is opposite to the clamping gap level;

[0037] S8. After the main assembly stops moving horizontally, check whether the bayonet is completely locked on the positioning block. After the locking is completed, use a socket wrench to continuously rotate the first bolt so that its upper part is pressed against the bottom of the horizontal plate of the crossarm. When the four first bolts are tightened, use the wire hanging operation insulating rod to lift the wire clamp to the vicinity of the corresponding live wire. Then, by manipulating the wire hanging operation insulating rod, the clamping mouth of the wire clamp is placed on the live wire. Then, the wire hanging operation insulating rod is appropriately pulled down so that the live wire is tightly attached to the upper part of the clamping mouth. Then, the wire hanging operation insulating rod is rotated to press the top screw. When the movable clamping block continues to rise and realizes the tightening and pressing of the lower part of the live wire, the [-shaped pressure hook rises to the upper limit position. Then, by moving the wire hanging operation insulating rod, the hanging ring is separated from the upper part of the wire hanging operation insulating rod, and then the built-in series gap lightning arrester is installed and fixed near the insulator under live conditions;

[0043] S5. After the four first bolts are loosened, the main body assembly and the built-in series gap arrester are driven by the lifting sleeve to move in the direction of the horizontal plate away from the crossarm. During the movement, the main body assembly is separated from the crossarm. After separation, the lifting sleeve is used to keep the main body assembly at a certain height, and then the hanging wire is lifted to operate the insulating rod so that the upper part of the [-shaped pressure hook is inserted into the hanging ring, and then the bottom of the hanging ring is inserted into the one-shaped groove. When the bottom of the hanging ring is inserted into the one-shaped groove, the [-shaped pressure hook is lowered to achieve stable pressure placement of the hanging ring in the one-shaped groove, and then the hanging wire is rotated to operate the insulating rod to drive the movable clamp to continuously descend. After the movable clamp is lowered to the lower limit position, the wire clamp is moved to separate it from the live wire, thereby realizing the disassembly of the built-in series gap arrester near the insulator under live conditions.

[0044] The beneficial effects of the present invention are:

[0045] 1. The structure of the present invention is simple and easy to process and manufacture. In the actual production process, it can be standardized and mass-produced, and then it can be fully promoted and applied in the field of power supply technology.

[0046] 2. After the operator uses the electric pole to climb to a certain height, the present invention can be used to realize the live installation or removal of the lightning arrester on the cross arm, thereby making the installation or subsequent removal of the lightning arrester safe and convenient.

[0047] 3. After the self-locking positioning plate completes self-locking, the U-shaped groove on the self-locking positioning plate and the U-shaped groove on the first horizontal plate are perpendicular to each other and are clamped up and down at the root of the insulator on the crossarm. The clamping method of the self-locking positioning plate and the first horizontal plate at the root of the insulator improves the installation safety and stability of the main assembly on the crossarm. Even if the bolts for tightening become loose, the main assembly can be effectively prevented from falling off the crossarm, thereby effectively preventing the arrester from falling off.

[0048] 4. The self-locking positioning plate can be stably maintained in the self-locking position by the joint action of the positioning block, the limit column and the spring, thereby improving its self-locking stability at the root of the insulator. At the same time, by utilizing the compression capacity of the spring, it is convenient to realize the upward rotation and opening of the self-locking positioning plate, thereby facilitating the unlocking operation of the self-locking positioning plate.

[0049] 5. By utilizing the limiting effect of the limiting column on the supporting lug, the self-locking positioning plate can be quickly opened and positioned. After the self-locking positioning plate is opened and positioned, it can ensure that the root of the insulator can be synchronously inserted into the first U-shaped groove and the second U-shaped groove, thereby facilitating the synchronous clamping of the first horizontal plate and the self-locking positioning plate on the root of the insulator.

[0050] 6. By using the grounding lead clamping assembly to clamp and fix the grounding lead led out from the bottom of the arrester, it is convenient to lay the grounding lead in a directional manner along the cross arm direction or the pole direction, thereby improving the laying reliability and aesthetics of the grounding lead.

DETAILED DESCRIPTION

[0069] The following will be combined with specific embodiments and attached Figure 1-16 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the present invention, rather than all the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0070] The present invention provides a lightning arrester non-stop power installation assembly (such as Figure 1 and 2As shown), it includes a main body component, a lifting sleeve, and a socket wrench. The main body component includes a first L-shaped plate 1, a second L-shaped plate 2, a self-locking positioning plate 3, a clamping component, and a grounding lead clamping component. The first L-shaped plate 1 and the second L-shaped plate 2 are both made of steel plates of a certain thickness. The first vertical plate 11 of the first L-shaped plate 1 and the second vertical plate 21 of the second L-shaped plate 2 are fixedly connected by a detachable connection method. In actual applications, the detachable function of the first vertical plate 11 and the second vertical plate 21 is used to facilitate the adjustment of the upper and lower relative positions of the first L-shaped plate 1 and the second L-shaped plate 2, and then facilitate The vertical distance between the annular electrode 821 on the annular electrode external series gap arrester 82 and the live wire is adjusted, so that after the annular electrode external series gap arrester 82 is fixedly installed, it is ensured that the distance between the annular electrode 821 and the live wire meets the installation specification requirements; when the built-in series gap arrester 83 is installed using the main body component, by adjusting the upper and lower relative positions of the first L-shaped plate 1 and the second L-shaped plate 2, it is also convenient to adjust the distance between the upper part of the built-in series gap arrester 83 and the live wire 84, so that the distance between the built-in series gap arrester 83 and the live wire 84 meets the installation specification requirements;A first U-shaped groove 121 is arranged on the first horizontal plate 12 of the first L-shaped plate 1. In practical applications, the first U-shaped groove 121 is used to be clamped at the root position of the insulator 81. The self-locking positioning plate 3 is rotatably arranged on the upper part of the first horizontal plate 12. A second U-shaped groove 31 is arranged on the self-locking positioning plate 3. A rotation limiting component for preventing the self-locking positioning plate 3 from rotating is arranged on the first horizontal plate 12. After the rotation limiting component realizes the rotation limiting of the self-locking positioning plate 3, there is an upper gap between the first U-shaped groove 121 and the second U-shaped groove 31. In the upper and lower overlapped area, in actual application, the root of the insulator 81 passes through the upper and lower overlapped area between the first U-shaped groove 121 and the second U-shaped groove 31. When the self-locking positioning plate 3 is in the locked position, the first U-shaped groove 121 and the second U-shaped groove 31 are in a mutually perpendicular state, thereby realizing the self-locking positioning plate 3 and the first horizontal plate 12 embracing the root of the insulator 81. At the same time, since the self-locking positioning plate 3 is arranged on the first horizontal plate 12, the first horizontal plate 12 can be effectively prevented from being separated from the root of the insulator 81, which helps to improve the clamping stability of the first L-shaped plate 1 on the cross arm 9. The clamping component is arranged at the lower side of the first horizontal plate 12, and the clamping component is used to realize the fixed installation of the first L-shaped plate 1 at the installation position. The second horizontal plate 22 of the second L-shaped plate 2 is used to realize the installation support of the annular electrode external series gap arrester 82 or the built-in series gap arrester 83. In practical applications, the clamping component is used to realize the fixed installation of the first L-shaped plate 1 on the cross arm 9. When the clamping component becomes loose on the cross arm 9, the first horizontal plate 12 and the self-locking positioning plate 3 are used to embrace the root of the insulator 82, so that the second L-shaped The annular electrode external series gap arrester 82 or the built-in series gap arrester 83 on the plate 2 is effectively fixed on the cross arm 9. During the normal installation process, the installation position of the insulator 81 is used as a reference to assist in positioning the entire device to the correct position. Before the first bolt 43 is tightened, it is ensured that the entire device is securely clamped at the root of the insulator 81. Therefore, the installation reliability of the annular electrode external series gap arrester 82 or the built-in series gap arrester 83 is improved as a whole, thereby effectively preventing the annular electrode external series gap arrester 82 or the built-in series gap arrester 83 from falling;The lifting sleeve includes a rectangular sleeve 61 and a first insulating rod 62.

When the first vertical plate 11 and the second vertical plate 21 are vertically inserted into the insertion groove 611, the bolt smoothly slides into the U-shaped through groove 612.

As the self-locking positioning plate 3 continues to rotate, when the bayonet 35 is completely moved to the top of the positioning block 122, the self-locking positioning plate 3 descends under the action of the spring 27 and gravity, thereby realizing the bayonet 35 being locked on the outside of the positioning block 122. When the self-locking positioning plate 3 is unlocked during high-altitude operation, in order to facilitate the rotation of the self-locking positioning plate 3, a plug-in hole 32 is set on the left side of the bayonet 35. Furthermore, a plug-in finger 613 is set on the upper part of the right side wall of the plug-in slot 611. When the plug-in finger 613 is inserted into the plug-in hole 32, it is convenient to use the lifting sleeve to realize the rotation unlocking of the self-locking positioning plate 3 at a high altitude position.

[0100] S7, horizontally move the main assembly to move it toward the horizontal plate direction of the cross arm 9, and during the continuous movement of the main assembly, the horizontal plate 91 of the cross arm 9 enters the clamping gap; the root of the insulator 81 enters the second U-shaped groove 31 and pushes the self-locking positioning plate 3 to rotate, thereby realizing the self-locking of the self-locking positioning plate 3;

[0101] S8. After the main assembly stops moving horizontally, check whether the bayonet 35 is completely locked on the positioning block 122. After the locking is completed, use a socket wrench to continuously rotate the first bolt 43 so that its upper part is pressed against the bottom of the horizontal plate of the cross arm 9. When the four first bolts 43 are tightened, use the wire hanging operation insulating rod 301 to lift the wire clamp 201 to the vicinity of the corresponding live wire 84, and then operate the wire hanging operation insulating rod 301 to make the clamping mouth of the wire clamp 201 be placed on the live wire 84, and then pull down the wire hanging operation insulating rod appropriately. 301 makes the live wire 84 close to the upper part of the clamping mouth, and then the wire-hanging operating insulating rod 301 rotates the pressing screw 3014 (that is, the upper fixing rod 3011 rotates), when the movable clamping block 2011 rises continuously and realizes the tightening pressing of the lower part of the live wire 84, the [-shaped pressing hook 3013 rises to the upper limit position, and then, by moving the wire-hanging operating insulating rod 301, the hanging ring 2013 is separated from the upper part of the wire-hanging operating insulating rod 301, and then the built-in series gap lightning arrester 83 is installed and fixed near the insulator 81 under the live condition;

[0102] The method for disassembling a built-in series gap arrester under power supply comprises the following steps:

[0103] S1. The operator uses the pole climbing tool to climb to a certain height of the pole, and then puts on insulating gloves;

[0104] S2. First, use a socket wrench to loosen the four first bolts 43 to a certain extent. The purpose of loosening the first bolts 43 is to smoothly realize the subsequent rotation and opening of the self-locking positioning plate 3. Therefore, the degree of loosening can be based on the shaking of the main assembly on the horizontal plate 91; then use a socket wrench or a lifting sleeve to push the self-locking positioning plate 3 upward and rotate it clockwise at the same time, so that the bayonet 35 is disengaged from the positioning block 122; when the lifting sleeve is used to push the self-locking positioning plate 3, the end of the plug-in finger 613 or the tapered cross bar 615 can be inserted into the plug-in hole 32, which facilitates the pushing and rotation of the self-locking positioning plate 3;

[0105] S3, after ensuring that the bayonet 35 is disengaged from the positioning block, the rectangular sleeve 61 is inserted into the lower part of the first vertical plate 11 and the second vertical plate 21, and the rectangular sleeve 61 is stably clamped at the lower part of the first vertical plate 11 and the second vertical plate 21;

[0106] S4, the lifting sleeve remains stationary, and then all four first bolts 43 are loosened using a socket wrench;

[0107] S5. After the four first bolts 43 are loosened, the main body assembly and the built-in series gap arrester 83 are driven by the lifting sleeve to move in the direction of the horizontal plate 91 away from the crossarm 9. During the movement, the main body assembly is separated from the crossarm 9. After separation, the lifting sleeve is used to keep the main body assembly at a certain height. Then, the hanging wire control insulating rod 301 is lifted to make the upper part of the [-shaped pressure hook 3013 inserted into the hanging ring 2013, and then, the bottom of the hanging ring 2013 is inserted into the one-shaped groove. When the bottom of the hanging ring 2013 is inserted into the one-shaped groove, the [-shaped pressure hook 3013 is lowered to achieve stable pressure placement of the hanging ring 2013 in the one-shaped groove. Then, the hanging wire control insulating rod 301 is rotated to drive the movable clamp 2011 to continuously descend. After the movable clamp 2011 is lowered to the lower limit position, the wire clamp 201 is moved to separate it from the live wire 84, thereby realizing the disassembly of the built-in series gap arrester 83 near the insulator under live conditions.

[0108] In the present invention, "up", "down", "front", "back", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0109] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
