Abstract

The utility model relates to a bus duct for low-voltage transmission and distribution. The utility model is a closed composite resin-injected bus duct which comprises naked buses (2) and a composite resin body (1); each naked bus is packed by the composite resin body and every two naked buses are separated by the composite resin body; a plurality of buses are solidified into an integrity by the composite resin body. The utility model which has good conducting and radiating performances and good impact resistance can be applied in damp environments, even in water.

Description

Totally-enclosed compound resin pouring bus groove

Technical field

The utility model relates to a kind of bus duct that is used for the low pressure power transmission and distribution.

Technical background

Bus duct is widely adopted in engineering, the bus duct of using morely in the engineering is a concentration bus duct at present, this bus duct heat radiation is best, but this bus duct requires the bus surface that burr, the inaccurate breakage of insulating barrier can not be arranged, otherwise will produce phase fault.For preventing phase fault, have or not burr should carry out exhaustive test to the surface of bus, but, have only the thickness and the number of plies that increase insulating barrier, but still can not prevent the appearance of phase fault owing to can only lean on naked eyes and feel fully to carry out.Adopt double insulated bus duct, though alternate can short circuit, weak heat-dissipating, exist stack effect, volume big, can only lean on heat loss through radiation, or strengthen the temperature rise that busbar cross-section overcomes bus duct.Owing to there is the gap that is full of air between the bus of double insulation bus duct, when the bus duct vertical run, just there is stack effect, therefore must cut off by mineral wool.But after having done in the bus duct to cut off, stoped flowing of hot-air, the temperature rise of aggravation bus duct, so the user only just adopts the double insulation bus duct in the specific (special) requirements place.

Summary of the invention

The purpose of this utility model is to provide a kind of totally-enclosed compound resin pouring bus groove, and this bus duct can not produce phase fault and stack effect, and perfect heat-dissipating can be used for wet environment, even uses in the water, and good impact resistance is arranged.

The utility model is achieved in that a kind of totally-enclosed compound resin pouring bus groove, comprise bare bus bar and compound resin body, every bare bus bar is wrapped up by the compound resin body, is separated by the compound resin body between bare bus bar and bare bus bar, and many bare bus bars are solidified into an integral body by the compound resin body.

Operation of the present utility model is the bare bus bar that processes by designing requirement length, put into and water injection molding, bare bus bar is watered injection molding and is separated certain distance, scribble release agent on the mould, compound resin poured into steep in the mixer, after injecting curing agent and abundant the stirring, slowly pour in the mould demoulding after the spontaneous curing into.Every bare bus bar of totally-enclosed like this compound resin pouring bus groove is wrapped up by the compound resin body, is separated by the compound resin body between bare bus bar and bare bus bar, and is solidified into an integral body by the compound resin body, and the profile of bus duct is decided by mould.Therefore totally-enclosed compound resin pouring bus groove can not produce phase fault and stack effect, and the heat loss through conduction performance is good, can be used for wet environment, even uses in the water, and has good impact resistance.

Description of drawings

Fig. 1 is the totally-enclosed compound resin pouring bus groove of a utility model structural representation.

Among the figure: 1 compound resin, 2 bare bus bars.

Embodiment

Referring to Fig. 1, Fig. 2, a kind of totally-enclosed compound resin pouring bus groove, comprise bare bus bar and compound resin body, bare bus bar can be copper bar or aluminium row, every bare bus bar is wrapped up by the compound resin body, separated by the compound resin body between bare bus bar and bare bus bar, many bare bus bars are solidified into an integral body by the compound resin body.The making of totally-enclosed compound resin pouring bus groove is that compound resin is slowly poured in the mould that bare bus bar is housed, and the demoulding obtains after spontaneous curing.Owing to certain interval is arranged and is full of the compound resin body between bare bus bar, even so bare bus bar have burr also can not produce phase fault, more can not produce stack effect; Because bus duct is by compound resin body heat loss through conduction, so heat dispersion is better than double insulation bus duct.Bus duct also can be used for wet environment, even works in the water.Because bare bus bar all wraps up by compound resin, so bus duct has good impact resistance, not only can save metal shell, also can use in corrosive environment.The selection of compound resin is very important, and the compound resin that present embodiment is selected for use can be in the bare bus bar temperature during up to 105 ℃, and insulation resistance still can keep more than the 20M Ω, and its insulation property are good.

Totally-enclosed compound resin pouring bus groove can be used as low voltage bus bar groove, also can be used as common phase high voltage bus groove.
