Description
Technical Field
[0001] This invention relates to the field of climbing umbrella skirt installation, and in particular to a live installation method for climbing umbrella skirts. Background Technology
[0002] Creeper skirts are insulating components made of high-temperature vulcanized fluorosilicone rubber through injection or molding. They are bonded to the upper surface of the original porcelain or glass insulator skirts with adhesive to form a composite insulator, increasing the creepage distance and thus preventing flashover. Currently, there are two main installation methods for creepper skirts. The first is power outage installation, which involves shutting down the high-voltage equipment intervals or the entire station and manually installing them by personnel climbing to heights. This method is time-consuming and labor-intensive, requiring electrical testing before installation, and some high-voltage equipment cannot be shut down. Therefore, power outage installation can only be used as an emergency measure and cannot be used for the routine installation of creepper skirts. The second method involves installing the creepper skirts directly onto the original porcelain or glass insulator skirts before the insulator leaves the factory. However, this method is only suitable for new high-voltage equipment and cannot meet the needs of high-voltage equipment already in use. Therefore, solving the installation problem of creepper skirts for existing high-voltage equipment is crucial. Summary of the Invention
[0003] In view of this, the present invention proposes a live installation method for climbing skirts, which enables the installation of climbing skirts on insulators under energized conditions without power outages and with high safety.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The present invention discloses a live-line installation method for a climbing umbrella skirt, wherein the live-line installation method employs a live-line installation device made of insulating material, the live-line installation device comprising an insulating rod, a pair of clamps made of insulating material, a suction cup mechanism disposed in each of the clamps, and a negative pressure air extraction pipe connected to the suction cup mechanism; wherein the insulating rod is inclined and has a hollow structure, and an insulating plate is disposed on its top; Both clamps are horizontally mounted on the insulating plate via an insulating shaft, with the two clamps corresponding vertically. The insulating ropes of the clamps pass through the insulating plate and the insulating rod in sequence and exit from the bottom of the insulating rod. The two suction cup mechanisms are arranged symmetrically in the upper and lower parts. Each suction cup mechanism has multiple insulating suction cups fixed on the clamping clamp, and the insulating suction cups of the two suction cup mechanisms are arranged symmetrically in the upper and lower parts. Each insulating suction cup is provided with an extrusion structure for extruding and bonding the climbing skirt to the insulator. The extrusion structure is a dry ice piston pusher, which has a storage container, a piston disposed in the storage container, a piston rod disposed on the piston, and a pusher fixed to the outer end of the piston rod. The piston divides the storage container into a first chamber and a second chamber. The side wall of the storage container corresponding to the piston has an inlet with a sealing plug, and the end of the cylinder wall of the storage container corresponding to the second chamber has an exhaust hole. The specific steps of the live-line installation method are as follows: Step S1: Wipe the surface of the insulator to be fitted with the climbing skirt clean; trim the climbing skirt according to the parameters of the insulator so that the neck size of the insulator is consistent with the neck of the climbing skirt; apply silicone adhesive evenly to the overlapping edge of the trimmed climbing skirt. Step S2: Divide the extrusion structure into multiple groups, fill the first chamber of the storage container of each group of extrusion structures with dry ice in sequence and seal it with a sealing plug, and then insert the extrusion structure into the insulating suction cup; wherein the time interval between filling dry ice between two adjacent groups of extrusion structures is greater than or equal to 30 seconds. Step S3: Connect the negative pressure suction line to the external vacuum equipment, and then draw a vacuum. The upper insulating suction cup is attached to the upper surface of the climbing umbrella skirt, and the lower insulating suction cup is attached to the lower surface of the climbing umbrella skirt. Hold the insulating rod and move the climbing skirt above the insulator. The upper clamp is positioned above the insulator, and the lower clamp is positioned below the skirt. Step S4: Pull the insulating rope down to close the clamping pliers, which in turn closes the creeper skirt, making the overlapping parts of the creeper skirt stick together; then release the vacuum in the negative pressure pumping line through the insulating vacuum release valve, so that the creeper skirt falls off and is put on the insulator. In step S5, the dry ice in the dry ice piston pusher vaporizes and expands. The carbon dioxide gas produced by the vaporization pushes the piston, causing the pusher at the end of the piston rod to compress the climbing skirt and the insulator, making the climbing skirt and the insulator fit tightly together, thus realizing the live installation of the climbing skirt.
[0005] The beneficial effects are as follows: The live-line installation equipment of the present invention is made entirely of insulating material to ensure safety; two clamping clamps are installed at an interval on the upper part of the insulating rod, each clamping clamp having an insulating suction cup. During installation, the lower suction cup acts on the insulator, and the upper insulating suction cup acts on the climbing skirt. The squeezing structure inside the suction cup can be used to make the climbing skirt press against the insulator (such as the original porcelain skirt and glass skirt), thereby realizing the live-line installation of the climbing skirt without power interruption, which is particularly suitable for existing high-voltage equipment.
[0006] The extrusion structure of this invention is made of insulating material and utilizes the principle of dry ice vaporization to achieve the pushing of the jacking component. The structure is ingenious and highly safe. Furthermore, the dry ice filling time of the multiple dry ice piston-type pushers is spaced out, allowing for pushing at different times and positions, effectively ensuring a tight fit between the climbing skirt and the insulator, resulting in excellent installation. When the piston moves to the vent and positions the vent in the first chamber, excess carbon dioxide gas is discharged from the vent, facilitating piston reset and the addition of dry ice to the first chamber, ensuring the reusability of each dry ice piston-type pusher.
[0007] Preferably, the negative pressure suction pipeline includes a main air pipe and branch pipes connected to the insulating suction cups of each suction cup mechanism. The two branch pipes are connected to the main air pipe, and the main air pipe passes sequentially through the insulating plate and the insulating rod, exiting from the bottom of the insulating rod. More preferably, the main air pipe is equipped with an insulating vacuum release valve; the branch pipes are equipped with pipe joints that mate with each of the insulating suction cups. The beneficial effect is that, during actual installation, a vacuum pump is connected to the main air pipe, effectively ensuring that each insulating suction cup has negative pressure adsorption performance.
[0008] Preferably, the insulating suction cup includes a mounting cylinder and an adsorption portion disposed at the edge of the cylinder opening. The mounting cylinder in this invention provides sufficient mounting space for the extrusion structure. In actual installation, the mounting cylinder can be a rectangular structure or a circular structure; a circular structure is preferred in this invention.
[0009] More preferably, the mounting cylinder is provided with an air extraction pipe inside its wall, and the outer end of the air extraction pipe is provided with a quick-connect fitting for easy connection, enabling quick connection between the insulating suction cup and the negative pressure air extraction pipe.
[0010] Preferably, the clamping pliers include a pair of hinged handles and a clamp head disposed at one end of each handle. The clamp head has an arc-shaped structure, and multiple insulating suction cups are spaced apart on each clamp head. Advantages: The arc-shaped clamp head of the present invention facilitates the suction of creepage skirts and their installation on the insulator.
[0011] More preferably, the other ends of the two clamp handles are connected by an insulating connecting rope, the upper part of which is tied together. In actual operation, the clamp heads can be closed by pulling the insulating rope downwards, making operation simple and convenient. More preferably, a return spring is provided in the middle of the two clamp handles to reset the clamp heads. When the insulating rope is released, the clamp handles can automatically open under the action of the return spring, so that the clamp heads are initially in the open state, facilitating the suction operation of the climbing skirt and making installation convenient.
[0012] More preferably, the lower part of the insulating rod is provided with a handle, and the insulating rope passes through the insulating rod and is tied to the handle. The handle is easy to hold and convenient to operate.
[0013] Compared with existing technologies, the live-line installation equipment in this invention is made entirely of insulating materials to ensure safe installation. Two clamping clamps are installed at the top of the insulating rod, spaced apart vertically. Each clamping clamp has an insulating suction cup. During installation, the lower suction cup acts on the insulator, while the upper insulating suction cup acts on the climbing skirt. The squeezing structure inside the suction cup can be used to press the climbing skirt against the insulator (such as the original porcelain skirt and glass skirt), thereby realizing the live-line installation of the climbing skirt without power interruption. It is particularly suitable for existing high-voltage equipment. Attached Figure Description

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.
[0023] It should be noted that, in the description of this invention, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0024] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0025] It should be noted that the insulator in this embodiment refers to the original porcelain skirt or glass skirt of the high-voltage equipment.
[0026] This invention proposes a live-line installation method for climbing umbrella skirts, which employs dedicated live-line installation equipment. For example... Figure 1-3 As shown, the live-line installation equipment includes an insulating rod 1 made of fiberglass, a pair of clamping clamps 2 made of insulating fiberglass, a suction cup mechanism provided in each clamping clamp 2, and a negative pressure suction pipe connected to the suction cup mechanism; the insulating rod 1 is inclined to provide space for the insulating rope 3 and the negative pressure suction pipe described later; the top of the insulating rod 1 is provided with an insulating plate 4 made of polyethylene board, the insulating plate 4 has an upper flat surface and a lower inclined surface, the top of the insulating rod 1 is fixed to the lower inclined surface, and the angle α between the insulating rod 1 and the upper flat surface is between 100° and 130°, so that the insulating rod 1 is inclined to facilitate hand holding and operation; The upper surface of the insulating plate 4 has a vertically arranged insulating shaft 5 made of insulating glass fiber. The clamping pliers 2 are horizontally arranged on the insulating shaft 5, and the two clamping pliers 2 are arranged vertically and alternately. The insulating rope 3 of the clamping pliers 2 passes through the insulating plate 4 and the insulating rod 1 in sequence and comes out from the bottom of the insulating rod 1. The opening and closing of the clamping pliers 2 can be controlled by pulling the insulating rope 3. Each clamp 2 is equipped with a suction cup mechanism, and the two suction cup mechanisms are arranged symmetrically above and below. Each suction cup mechanism has multiple insulating suction cups 6 fixed on the clamp 2. Each insulating suction cup 6 is equipped with a pressing structure for pressing the climbing skirt 7 onto the insulator F, so as to achieve a tight fit between the climbing skirt 7 and the insulator F.
[0027] The invention is made entirely of insulating material to ensure safety. Two clamping clamps 2 are installed at an interval on the upper part of the insulating rod 1. Each clamping clamp 2 has an insulating suction cup 6, which acts on the climbing skirt 7 to prevent it from falling. When the climbing skirt 7 is closed, the squeezing structure inside the insulating suction cup 6 can be used to make the climbing skirt 7 press against the insulator F (such as the original porcelain skirt and glass skirt), thereby realizing the live-line installation of the climbing skirt 7 without power interruption, which is particularly suitable for existing high-voltage equipment.
[0028] Combination Figure 1It is known that the negative pressure suction pipeline includes a main air pipe 8.1 and branch pipes 8.2 connected to the insulated suction cups 6 of each suction cup mechanism. Both the main air pipe 8.1 and the branch pipes 8.2 are made of insulated pipes, and each branch pipe 8.2 is connected to the main air pipe 8.1 to ensure the negative pressure suction performance of the suction cups of each suction cup mechanism. The main air pipe 8.1 passes downward through the insulating plate 4 and the insulating rod 1 in sequence, and exits from the lower part of the insulating rod 1. The exiting part of the main air pipe 8.1 is equipped with an insulated vacuum release valve 8.3 for easy vacuum release. The branch pipes 8.2 are equipped with pipe joints 8.4 that mate with the insulated suction cups 6 one by one, which can realize the quick connection between the insulated suction cups 6 and the branch pipes 8.2.
[0029] Combination Figure 2 It is known that the insulating suction cup 6 includes a mounting cylinder 6.1 and an adsorption part 6.2 disposed at the edge of the cylinder opening of the mounting cylinder 6.1. The adsorption part 6.2 has an adsorption surface, which can act on the climbing umbrella skirt 7 during use to facilitate adsorption. In actual installation, the mounting cylinder 6.1 is fixed on the clamping head 2.2 of the clamping pliers 2 to realize the connection between the insulating suction cup 6 and the clamping head 2.2. An air extraction pipe 6.3 is provided inside the cylinder wall of the mounting cylinder 6.1, and a quick connector 6.4 is provided at the outer end of the air extraction pipe 6.3. The quick connector 6.4 can be quickly connected to the pipe connector 8.4, thereby realizing the quick connection between the insulating suction cup 6 and the negative pressure air extraction pipeline.
[0030] Combination Figure 2 It is understood that the extrusion structure is a dry ice piston-type pusher made of insulating material, which includes a storage container 9.1 for holding dry ice, a piston 9.2 disposed within the storage container 9.1, a piston rod 9.3 disposed on the piston 9.2, and a pusher fixed to the outer end of the piston rod 9.3. The piston 9.2 divides the container into a first chamber and a second chamber. The piston rod 9.3 extends outward from the second chamber and is fixed to the pusher, which is preferably a pusher plate 9.4. An inlet hole is provided on the side wall of the storage container 9.1 opposite to the piston 9.2 (the side wall corresponding to the first chamber), and a sealing plug 9.5 (made of insulating material) is screwed into the inlet hole. When dry ice is placed into the first chamber, the sealing plug 9.5 is used to seal the inlet hole to ensure the pushing stroke of the piston 9.2 and the pusher plate 9.4. An exhaust hole 9.6 is provided at the end of the cylinder wall of the storage container 9.1 corresponding to the second chamber. When the gas pushes the piston rod 9.3 beyond its pushing stroke, the exhaust port 9.6 connects to the first chamber, allowing excess carbon dioxide gas to escape from the first chamber. This facilitates the refilling of dry ice into the first chamber and ensures the reusability of each dry ice piston actuator. Furthermore, during actual installation, the gap between the exhaust port 9.6 and the wall of the mounting cylinder 6.1 is designed to ensure the proper discharge of excess carbon dioxide gas.
[0031] During installation, the vaporization of dry ice causes the piston rod 9.3 to extend outward. The push plate 9.4 at the outer end of the piston rod 9.3 compresses the creepage skirt 7, thereby squeezing out the gas between the creepage skirt 7 and the insulator F, ensuring the bonding effect.
[0032] In actual manufacturing, the mounting cylinder 6.1 and the storage container 9.1 have the same structure, which can be either rectangular or circular. In this embodiment, both the mounting cylinder 6.1 and the storage container 9.1 are circular.
[0033] Combination Figure 1 and Figure 3 It is known that the clamping pliers 2 includes a pair of hinged handles 2.1 (both handles 2.1 are hinged to an insulating shaft) and a clamp head 2.2 located at one end of each handle 2.1. The clamp head 2.2 has an arc-shaped structure, which facilitates the closing of the climbing umbrella skirt 7. The other end of the handle 2.1 is connected by an insulating connecting rope 10, and the upper part of the insulating rope 3 is tied together with the insulating connecting rope 10. In actual operation, the clamp head 2.2 can be closed by pulling the insulating rope 3 downwards, which is simple and convenient. A return spring 2.3 is provided in the middle of the two handles 2.1 to open the two clamp heads 2.2. When the insulating rope 3 is released, the handles 2.1 can automatically open under the action of the return spring 2.3.
[0034] Combination Figure 1 It is known that a handle 11 is provided at the lower part of the insulating rod 1. The insulating rope 3 passes through the insulating rod 1 and is tied to the handle 11. A through groove is opened on the insulating rod 1 with the same inclination direction as it. The handle 11 can move in the through groove. The insulating rope 3 can be pulled down by moving the handle 11, which is convenient for operation.
[0035] In this invention, the clamping clamp 2 is in a normally open state. Four insulating suction cups 6 are installed on each clamping head 2.2 of the clamping clamp 2. To ensure a tight fit between the creeper skirt 7 and the insulator F, the insulating suction cups 6 are divided into four groups. The grouping method of the insulating suction cups 6 on the upper and lower clamping clamps 2 is described below. Figure 8 Combining Figure 8 It can be seen that the insulating suction cups marked a1, a2, a3 and a4 form one group, the insulating suction cups marked b1, b2, b3 and b4 form another group, the insulating suction cups marked c1, c2, c3 and c4 form another group, and the insulating suction cups marked d1, d2, d3 and d4 form yet another group. Due to the time difference in the dry ice filling time of the dry ice piston pusher in the four groups of insulating suction cups 6, the push plate 9.4 in the four groups of insulating suction cups is pushed in batches at intervals, effectively ensuring the installation effect of the climbing umbrella skirt 7.
[0036] The live-line installation method for the climbing umbrella skirt of the present invention includes the following specific steps: Step S1: Wipe the surface of insulator F, where the additional climbing skirt will be installed, clean it thoroughly. The surface of this skirt must be free of moisture and oil. See insulator F for details. Figure 5 Trim the creepage extension skirt 7 according to the parameters of insulator F so that the neck size of insulator F matches the neck size of creepage extension skirt 7. Then, evenly apply adhesive (preferably silicone sealant) to the overlap of the trimmed creepage extension skirt 7. See the details for the creepage extension skirt. Figure 4 ; Step S2: Divide the dry ice piston pushers into multiple groups, fill the first chamber of the storage container 9.1 of each group of dry ice piston pushers with dry ice in sequence and seal it with a sealing plug 9.5, and then insert the dry ice piston pushers into the mounting cylinder 6.1 of the insulating suction cup 6; wherein the dry ice filling time interval between two adjacent groups of dry ice piston pushers is greater than or equal to 30s, so as to realize the batch pushing and squeezing of the push plate 9.4; Step S3: Connect the negative pressure evacuation line to an external vacuum equipment (such as a vacuum pump), and then evacuate the vacuum. The upper insulating suction cup 6 is attached to the upper surface of the creeper skirt 7, and the lower insulating suction cup 6 is attached to the lower surface of the creeper skirt 7. Holding the insulating rod 1, the creeper skirt 7 is positioned above the insulator F. The upper clamping clamp 2 is positioned above the insulator F, and the lower clamping clamp 2 is positioned below the skirt. See details... Figure 6 ; After the climbing skirt 7 is in place, pull the insulating rope 3 downward to close the clamp head 2.2, and then close the climbing skirt 7; use the insulating vacuum valve 8.3 to release the vacuum of the insulating suction cup, so that the climbing skirt 7 falls off and is put on the insulator F from top to bottom; In step S5, the dry ice in the dry ice piston actuator vaporizes and expands. The carbon dioxide gas generated by the vaporization of the dry ice pushes the piston 9.2, causing the piston rod 9.3 to extend outward, thereby compressing the creepage-enhancing skirt 7 and the insulator F, making the creepage-enhancing skirt 7 and the insulator F fit tightly together and expelling the gas in the adhesive. When the pushing stroke is exceeded, the excess carbon dioxide gas is discharged through the exhaust port to relieve pressure, realizing the live installation of the creepage-enhancing skirt 7 on the insulator F. See details below. Figure 7 In this process, the dry ice in the dry ice piston actuator is vaporized in batches, thereby enabling the push plate to be pushed in batches, so as to make the climbing skirt as close as possible to the insulator F.
[0037] In this invention, multiple climbing skirts 7 can be continuously installed under power by repeating steps S1-S5.
[0038] Finally, it should be emphasized that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
