Abstract
The invention discloses a composite sleeve penetrating through a cabinet. The composite sleeve comprises a power bus pipe composed of an electric conduction copper bar core, wherein the electric conduction copper bar core is at least wrapped by a composite silicone rubber layer, a flange plate is arranged in the middle of the power bus pipe, the power bus pipe is divided into a first power bus pipe section and a second power bus pipe section through the flange plate, and umbrella skirts are arranged on the outer surface, located on the first power bus pipe section, of the composite silicone rubber layer. The composite sleeve has the advantages of being long in creepage distance, capable of resisting oxidation, high in pollution resistant capacity and convenient to install, and the service life of the high-voltage switch cabinet can be effectively prolonged.
Description
Technical field
The present invention relates to the sleeve pipe that a kind of energized conductor passed or introduced wall, electric equipment metal shell, be specifically related to a kind of compound cabinet sleeve pipe of wearing that high-voltage switch gear is used cashier's office in a shop.
Background technology
The cabinet sleeve pipe of wearing using in existing high-tension switch cabinet adopts epoxy resin formula bushing mostly, although these sleeve pipe insulation property can reach instructions for use, but the copper bar that can only be applied between high-tension switch cabinet and switch cubicle is worn cabinet installation, and while installing, can only make copper bar level or at right angle setting, can not adjust arbitrarily angled; Simultaneously, when high-tension switch cabinet copper bar is connected outward with cabinet in needs connecting cabinet, as use switch cubicle epoxy resin bushing, because existing epoxy resin bushing is creepage less than distance, the outside a large amount of dust of switch cubicle makes the anti-pollution characteristic of epoxy resin bushing and anti-fouling flashover performance all can not reach specification requirement effect, cause pollution flashover electric discharge problem, cause switch cubicle device fails, and epoxy resin formula bushing is oxidizable in high temperature filthy environment, cause that existing to wear cabinet Service Life of Casing short.
Summary of the invention
The object of the present invention is to provide a kind of creepage ratio apart from large, resistance to oxidation, the antifouling ability compound cabinet sleeve pipe of wearing strong, easy for installation.
For achieving the above object, a kind of compound cabinet sleeve pipe of wearing of the present invention, comprise the power bus-bar pipe being formed by conduction copper rod core, described conduction copper rod core is at least coated one deck composite silicone rubber layer outward, the middle part of power bus-bar pipe is provided with ring flange, ring flange is divided into first paragraph power bus-bar pipe and second segment power bus-bar pipe by power bus-bar pipe, and the composite silicone rubber layer outer surface of first paragraph power bus-bar pipe is provided with full skirt.
Between described conduction copper rod core and composite silicone rubber layer, be also provided with epoxy resin layer.
The two ends of described power bus-bar pipe are equipped with stainless steel end cap.
Adopting after technique scheme, is conductor by take conduction copper rod core, has increased flow conductivity, prevent large electric current by time bus pipe overheated; By covering composite silicone rubber layer outward as insulation material at conduction copper rod core, outer surface utilizes hydrophobicity and the oxidation resistance that composite silicone rubber is good, effectively protects the insulation property of bus pipe; The composite silicone rubber layer outer surface of first paragraph power bus-bar pipe is set as umbrella skirt construction, strengthens the creepage than distance of bus pipe, effectively solves pollution flashover electric discharge problem, greatly strengthens the stability of bus pipe performance.
The present invention has following characteristics and advantage:
1, withstand voltage insulation property are high;
2, realize the arbitrarily angled installation of copper bar, improve convenience is installed;
3, antifouling ability is strong;
4, creepage larger than distance;
5, oxidation resistent susceptibility is strong;
6, simple in structure, easily installation, non-maintaining.
Accompanying drawing explanation
Fig. 1 is a kind of compound cabinet sleeve structure schematic diagram of wearing of the present invention;
Fig. 2 is that Fig. 1 is along A-A to cutaway view.
Embodiment
Below in conjunction with accompanying drawing, a kind of compound cabinet sleeve pipe of wearing of the present invention is described further;
From Fig. 1, Fig. 2, a kind of compound cabinet sleeve pipe of wearing of the present invention, comprise the power bus-bar pipe 10 being formed by conduction copper rod core 1, the outer at least coated one deck composite silicone rubber layer 3 of described conduction copper rod core 1, the middle part of power bus-bar pipe 10 is provided with ring flange 4, ring flange 4 is divided into first paragraph power bus-bar pipe 5 and second segment power bus-bar pipe 6 by power bus-bar pipe 10, and composite silicone rubber layer 3 outer surface of first paragraph power bus-bar pipe 5 are provided with full skirt 31.
The technology of the present embodiment is mainly solved by the following technical programs: by conduction copper rod core 1 outer cladding composite silicone rubber layer 3 and epoxy resin layer 2, improve oxidation resistance; By the middle part at power bus-bar pipe 10, ring flange 4 is set, ring flange 4 is divided into first paragraph power bus-bar pipe 5 and second segment power bus-bar pipe 6 by power bus-bar pipe 10, composite silicone rubber layer 3 outer surface of first paragraph power bus-bar pipe 5 are provided with full skirt 31, the creepage distance that compares of bus pipe 10 increases electric power, effectively solve electric discharge problem, strengthen the stability of power bus-bar pipe 10 performances.
In the present embodiment, the two ends of described power bus-bar pipe 10 are equipped with stainless steel end cap 7, can strengthen overall appearance, can play all pressure effects again, and the pollution flashover electric discharge of conduction copper rod core 1 is had to good inhibitory action; By ring flange 4, power bus-bar pipe 10 is installed on the cabinet wall of high-tension switch cabinet, with trip bolt, ring flange 4 is fastening, realize easily install, non-maintaining object; Two of the present invention is conduction copper rod core 1, while installing and using, as long as copper bar to be connected need to be beaten to the hole with copper contact rod core 1 corresponding size, back-out the crimping copper screw cap on conduction copper rod core 1, copper bar is enclosed within on conduction copper rod core 1, tighten crimping copper screw cap, copper bar to be connected so just can, with on the arbitrarily angled conduction copper rod core 1 that is fixed on power bus-bar pipe 10 two, be realized copper bar different angles and be installed again.
