Abstract
The utility model relates to a bus duct which is used for low voltage power transmission and distribution, in particular to a fully sealed insulating cement poured bus duct, comprising an aluminum shell and an aluminum bus. The utility model is characterized in that the output end of the aluminum bus is welded with a copper output end; the bare aluminum buses are separated through an insulating clapboard and are coated by the insulating cement. The bar aluminum bus, the insulating clapboard and the insulating cement are sealed inside the aluminum shell. The insulating cement takes an insulating cement which has a thermal resistance temperature of 128 degrees. The utility model has the advantages of slight, low price, no alternate short and stack effect, good heat sink performance and strong moisture resistance capability. The utility model is suitable to be used for indoor power transmission and distribution, and also is used for power transmission and distribution in moist environment.
Description
Technical field
The utility model relates to a kind of bus duct that is used for the low pressure power transmission and distribution.
Background technology
Bus duct is used widely in engineering, and at present with the most use in the engineering is copper busbar, this bus duct good conductivity, and electroplating surfaces with tin is convenient, but this bus duct Heavy Weight costs an arm and a leg.So produced the aluminium busbar groove, owing to the easily oxidation of aluminium busbar surface, need adopt the tin bar of special formulation for this reason, ward off tin on the aluminium surface, perhaps at the aluminium copper coating, its complex process.
Concentration bus duct easily is short-circuited because bus is close together; Then there is stack effect in the air type bus duct, and the sealing of these two kinds of bus ducts generally can only reach IP54, so moisture resistance is poor.
The utility model content
The purpose of this utility model is to provide a kind of hermetically sealed insulating cement cast aluminum bus duct, and this bus duct is in light weight, and price is low, can not produce phase fault and stack effect, perfect heat-dissipating, and moisture resistance is strong.
The utility model is achieved in that a kind of hermetically sealed insulating cement cast aluminum bus duct, comprise aluminium shell, aluminium busbar, it is characterized in that: the output of aluminium busbar connects the copper output through melting welding, be insulated dividing plate between naked aluminium busbar and naked aluminium busbar and separate and be insulated glue parcel, naked aluminium busbar, insulating barrier and insulating cement are sealed in the aluminium shell.
Described insulating cement is that heat resisting temperature is 128 ℃ a insulating cement.
Operation of the present utility model is that two ends and middle output are put into the aluminium shell with copper output in the method melting welding of chemical melting welding the naked aluminium row who processes by designing requirement length, separates and fixes casting insulated then glue with insulating barrier.Naked like this aluminium busbar and insulating barrier are insulated glue and pour into an integrated entity and be sealed in the aluminium shell.Therefore hermetically sealed insulating cement cast aluminum bus duct can not produce phase fault, does not have stack effect yet, perfect heat-dissipating, and moisture resistance is strong, can be used for wet environment, and in light weight, and is easily manufactured, and price is low.
Description of drawings
Fig. 1 is the hermetically sealed insulating cement cast aluminum of a utility model bus duct structural representation.
Among the figure: 1 aluminium shell, 2 aluminium busbars, 3 bronze medal links, 4 bronze medal outputs, 5 insulating cements.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of hermetically sealed insulating cement cast aluminum bus duct comprises rectangle aluminium shell 1, aluminium busbar 2, copper output 4, copper link 3 and insulating cement 5.2 of naked aluminium busbar 2 and naked aluminium busbars are insulated dividing plate and separate and fix and be insulated glue 5 parcel, and naked aluminium busbar 2, insulating barrier and insulating cement 5 are formed one and be sealed in the aluminium shell 1.The output of aluminium busbar 2 connects copper output 4 through melting welding, and the middle output of aluminium busbar 2 connects copper link 3 through melting welding.Insulating cement 5 employing heat resisting temperatures are 128 ℃ insulating cement.
Therefore the hermetically sealed insulating cement cast aluminum of the utility model bus duct has overcome the oxide layer that the easy oxidation in aluminium busbar surface is produced because the connection between bus and the output of bus are copper bus-bars, and the defective of bad mechanical strength.Take chemical melting welding between the metallic copper aluminium, reached molecule combination between the copper aluminium, got rid of contact resistance.Adopting fire-retardant, heat resisting temperature is 128 ℃ insulating cement, has reached hermetic purpose.
The hermetically sealed insulating cement cast aluminum of the utility model bus duct is applicable to indoor power transmission and distribution, also can be used for the power transmission and distribution in the wet environment.
Claims (2)
1. hermetically sealed insulating cement cast aluminum bus duct, comprise aluminium shell, aluminium busbar, it is characterized in that: the output of aluminium busbar connects the copper output through melting welding, be insulated dividing plate between naked aluminium busbar and naked aluminium busbar and separate and be insulated glue parcel, naked aluminium busbar, insulating barrier and insulating cement are sealed in the aluminium shell.
2. hermetically sealed insulating cement cast aluminum bus duct according to claim 1 is characterized in that: insulating cement is that heat resisting temperature is 128 ℃ a insulating cement.
