Description

Technical Field

[0001] The invention relates to the technical field of distribution network linear insulating terminal shields, and in particular to an insulating rod method-operated bird-proof insulating protective shield and a forming method thereof. Background Art

[0002] Birds move, nest and roost on power line towers, and are likely to touch live wires, causing short circuits, tripping and other accidents, which seriously affect the safe and stable operation of the power system and cause a large amount of economic losses. Installing bird-proof insulating covers on straight insulators in the bare distribution lines can prevent birds from contacting exposed wires and joints, and avoid economic losses caused by power outages due to phase-to-phase short circuits, grounding and other factors.

[0003] On the 10kV high-voltage distribution network, the main bird-proof insulating protective cover currently used is made of vulcanized silicone rubber material, which has the natural softness of rubber products. When working without power outages, it can only be installed with insulating gloves. The efficiency of high-altitude operations is low, and the operator's skill level and physical fitness are required to be high. In addition, there are certain safety risks in the operation process.

[0004] The use of insulating rods can keep workers away from contact with live parts, improving the safety of operations. At the same time, the use of insulating rods can realize automated operations, reduce labor intensity, and improve work efficiency and construction costs.

[0005] The bird-proof insulating protective cover used for the linear insulated terminal is a long tube structure. Since the silicone rubber material is soft, the current insulating protective cover cannot maintain its static shape during lifting and installation, and cannot meet the technical requirements of remote installation by the insulating rod operation method. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a bird-proof insulating protective cover and a forming method for insulating rod operation.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: The utility model discloses a bird-proof insulating protective cover for insulating pole method operation, comprising an insulator protective cover and a lifting ring located at the top thereof, wherein a wire protective cover I and a wire protective cover II are respectively arranged on both sides of the insulator protective cover, the wire protective cover I and the wire protective cover II are symmetrically arranged with respect to the insulator protective cover, openings are arranged at the lower ends of the wire protective cover I and the wire protective cover II, and the opening edges of the wire protective cover I and the wire protective cover II are respectively correspondingly arranged with a card edge I and a card edge II, and a detachable limiting structure is arranged on the card edge I and the card edge II.

[0008] Preferably, the detachable limiting structure includes a buckle, which is a flat spindle structure, one end of which is a conical structure, and a plurality of sockets corresponding to the buckle are provided on both the card edge I and the card edge II.

[0009] Preferably, the insulator protection cover is an inverted circular bowl-shaped structure.

[0010] Preferably, a composite material conformal skeleton is embedded in the middle layer of the insulator protection cover, the conductor protection cover I and the conductor protection cover II.

[0011] A method for forming a bird-proof insulating protective cover by an insulating rod method comprises the following steps: a composite material conformal skeleton forming process → a prefabricated part vulcanization forming process → a bird-proof insulating protective cover vulcanization process.

[0012] Preferably, the composite material conformable skeleton forming process comprises the following steps: (1) Providing a set of composite material conformable skeleton forming molds, which are a mold-matching structure of a conformable skeleton forming female mold and a conformable skeleton forming male mold; (2) The insulating fibers are laid in the fiber layer depression of the female mold cavity of the conformable skeleton forming mold to form a hollow skeleton structure, and liquid resin is brushed on the insulating fibers. The resin penetrates the insulating fibers. The resin is a high-temperature resin, and the conformable skeleton of the composite material is made of silicone rubber; (3) Close the positive mold for forming the conformable skeleton, lock the mold, and heat and cure; (4) After the mold has cooled, open the mold, take out the product, and remove the burrs.

[0013] Preferably, the preform vulcanization molding process includes the following steps: (5) Providing a set of preform vulcanization molds, which are the mold-matching structure of the preform vulcanization female mold and the preform vulcanization male mold; (6) placing the formed composite material conformable skeleton into the preform vulcanization female mold, and positioning the conformable skeleton by the concave shape of the female mold working surface; (7) Spray a layer of glue on the composite material conformable skeleton. After curing, it can enhance the bonding strength between the composite material conformable skeleton and the silicone rubber material, avoiding debonding and delamination due to the inertia of the silicone rubber surface; (8) Put the silicone rubber raw material into the preform vulcanization female mold, close the preform vulcanization male mold, close the vulcanizing press plate, and vulcanize. The working surface of the male mold only contacts the silicone rubber material; (9) After vulcanization is completed, the preform is taken out, the composite material conformal skeleton is located on the inner side of the preform, and the burrs are removed.

[0014] Preferably, the vulcanization process of the bird-proof insulating protective cover comprises the following steps: (10) Providing a set of vulcanization molds, including a protective cover vulcanization male mold, a protective cover vulcanization upper female mold, and a protective cover vulcanization lower female mold; (11) Put the prefabricated part on the protective cover vulcanization positive mold and apply a layer of glue on the outer surface to avoid debonding and delamination due to the inertia of the silicone rubber surface; (12) placing the silicone rubber raw material into the protective cover vulcanization lower female mold, closing the protective cover vulcanization upper female mold and the protective cover vulcanization lower female mold, and heating and vulcanizing; (13) After vulcanization is completed, the product is taken out and the composite material conformal skeleton is located in the middle of the thickness of the silicone rubber; (14) Glue and assemble the lifting ring on the workpiece, insert the assembly buckles into all the sockets of the card edge I, and complete the component assembly of the bird-proof insulating protective cover.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the conductor protection cover and the card edge are made of an integral silicone rubber, which can be used as a 10kV and 20kV insulator protection cover and has good universality on distribution network lines; the insulator and the nearby bare conductors can be insulated and isolated to prevent birds from touching high-voltage live bodies during activities, causing short circuits, grounding and other faults in the line, thereby ensuring the safe operation of the power line and avoiding economic losses caused by power outages.

[0016] The insulator protection cover and the conductor protection cover are embedded with a high-rigidity composite material insulation skeleton to ensure the overall rigidity and keep the appearance unchanged when lifting it at any part. The lifting ring in the middle of the transformer cover can be inserted into the hook ring of the gun-type insulation operating rod, and the insulation rod operation method can be implemented for installation. It can keep the operators away from contacting the live parts, improve the safety of the operation, and further use the insulation rod to realize automated operation, reduce labor intensity, improve operation efficiency and construction costs, and has a good promotion prospect.
