Abstract

The utility model discloses a high grade protective solid insulating bus duct which is characterized in that: a dual layer high-temperature resistance mica insulating belt(2) is wrapped outside a carrier copper bar(10). The copper bar and the mica insulating belt are then compacted by a heat-shrink insulating bushing(8). A shell(5) with arched bottom and top and two lateral shell proximate matters(4) are welded into a groove body, the assembled carrier copper bar assembly(1) is installed inside a groove. Surrounding of the carrier copper bar assembly(1) inside the groove is filled by CEC resin casting. An output power source faucet(9) is arranged at any place on top of the arched shell(5). The utility model has the property of high grade insulating protection and water proof property. The utility model also has the advantages of small size, light weight, large load current, excellent corrosion-resistant property, long service life and maintenance-free.

Description

High-grade protection type solid insulation bus duct

The utility model relates to high and low voltage bus groove, refers in particular to the bus duct that adopts high-grade protection type solid insulation.

The power supply of at present general high level or heavy construction or industrial enterprise is transported to power distribution cabinet, is transported to the floor factory building by power distribution cabinet again by transformer.The power transmission busbar that each power unit adopted generally adopts assembled, and this class bus duct has following two point defects: 1, in order to keep better heat radiating effect, the insulating spacer that is adopted between copper bar and copper bar is all thicker big, cause bus bulky, big from weight, a large amount of locus have been taken, give construction and fixedly brought great difficulty, and firm degree is also lower; 2, can not contact water and liquid, particularly can not be immersed in the liquid and work.

The purpose of this utility model is improved at the shortcoming in the background technology, provides a kind of and by CEC synthetic resin conducting copper is carried out integrated poured high-grade protection type solid insulation bus duct after the certain rule arrangement is fixing.

The technical scheme that realizes the utility model purpose is such: the skin of carrier copper bar twines double-deck high temperature resistant mica insulation band, the reusable heat insulating sleeve that contracts tightens copper bar and mica insulation band, the end, top arcuate-shaped housings and two blocks of side shell section bars are welded into a cell body, the carrier copper bar assembly that combines is loaded in the groove, fill with the CEC resin-cast in all around space of carrier copper bar assembly in groove, and the out-put supply socket is opened in the optional position on the arcuate-shaped housings of top.

The bus duct core body that is poured into by CEC synthetic resin has good heat-conducting, and increased area of dissipation, make the temperature rise of high-grade protection type solid insulation bus duct very low, adopt the utility model can make the degree of protection of bus duct bring up to IP67, every performance index all can meet and exceed GB7251.1～2-1997 standard, can be in the rated voltage of rated current and 115% or ambient temperature-25 ℃ to+50 ℃ and height above sea level long-term operate as normal below 4000 meters; The insulation resistance that can make each bus duct unit is all greater than 20M Ω, owing to be integrated pouredly not corroded by any corrosion thing, so useful life is long especially, add that adopting side shell and end shell to be welded into cell body pours into a mould, and has saved the die cost in the casting process.

The utility model simultaneously also routinely the bus duct socket bus that equally is processed into any distance with the outside branch of jack box; The employing transition joint connects, and partly applies one deck solid insulation protective agent in connection, and field joint head place cast CEC synthetic resin can be installed and used high-grade protection type solid insulation bus duct according to the scene and required to connect into random length and position trend.

The arc section bar that shell of the present utility model can adopt carbon steel sheet to make also can adopt materials such as aluminium alloy or stainless steel.

The utlity model has high-grade insulating protection and rainproof, water resistance, have that volume is little, in light weight, load current is big, intensity is high, anti-moving strong, advantages such as decay resistance is strong, degree of protection is high, long service life, maintenance-free of steady heat stabilizing power.Because CEC synthetic resin has good fire-retardant fireproof performance, can make fireproof bus duct as requested simultaneously, press the test of GB9978 standard combustion curve, fire resistance period can reach 35min, and has improved the electric property and the mechanical performance of bus-bar system.

The utility model execution mode is provided by the following drawings:

Accompanying drawing 1 is the three-dimensional appearance design sketch

Accompanying drawing 2 is front views

Accompanying drawing 3 is Fig. 2 vertical views

Accompanying drawing 4 is Fig. 2 end views

Accompanying drawing 5 is insulation busbar internal anatomys

1-insulating carrier copper bar assembly among the figure, 2-is high temperature resistant mica insulation band, 3-CEC synthetic resin, 4-side shell section bar, 5-top, end arcuate-shaped housings, 6-groove, 7-top end shell bow shoulder, 8-pyrocondensation insulating sleeve, 9-out-put supply socket, 10-carrier copper bar.

The concrete structure of the utility model execution mode is described below with reference to the accompanying drawings:

From Fig. 1 and the high-grade as can be known protection type solid insulation of Fig. 5 bus duct is to be twined by the zinc-plated back of carrier copper bar (10) to go up double-deck high temperature resistant mica insulation band (2), the high temperature resistant mica insulation band (2) that will wind with pyrocondensation insulating sleeve (8) tightens, high temperature resistant mica tape and copper bar closely are bonded together, promptly are processed into insulating carrier copper bar assembly (1); End arcuate-shaped housings (5) and two blocks of side shell section bars (4) firmly are welded into a cell body, it is certain regularly arranged good that insulating carrier copper bar assembly (1) is pressed, firmly be welded into cast CEC synthetic resin (3) in the cell body at insulating carrier copper bar assembly (1) with by end arcuate-shaped housings (5) and two blocks of side shell section bars (4) then, CEC synthetic resin (3) is in aggregates with three skin solidifies with insulating carrier copper bar assembly after treating natural cooling, go up welding top arcuate-shaped housings (5) at left and right sides shell section bar (4) again, need go up the optional position in top arcuate-shaped housings (5) by actual use then and open out-put supply socket (9), and with out-put supply socket (9) securely driving fit on top arcuate-shaped housings (5).Promptly make to this high-grade protection type solid insulation bus duct and to finish.The size specification of busbar can be according to the size of current design alternative of being carried, and power supply output socket any distance, quantity design is according to actual needs reserved, and the appearance and modeling of high-grade protection type solid insulation bus duct can design arbitrarily.

The high-grade protection type solid insulation of the utility model bus duct is because compactness firm in structure can be made into various threeways, elbow, top in this way arbitrarily, and the insulating joint of employing variety of way connects into any trend and some length arbitrarily between every joint.Install at corresponding mounting bracket of employing and on-the-spot building, make whole high-grade protection type solid insulation bus duct can guarantee of the insulation safety conveying of the electric current of any size in any place and direction, again can waterproof and dustproof, anti-tampering, and easy installation and reliable.
