Abstract
The utility model relates to an air-type insulation bus bar duct which comprises a plurality of copper bars, and is characterized in that each copper bar is disposed in a caulking groove which is disposed in a bakelite isolation support which can be fixedly connected with each other by bolts, the outer side of the connected bakelite isolation supports is surrounded by a plate-steel, each copper bar has a thermoplastic insulating sleeve and a nickel-plate on the surface of the each copper, and the bakelite isolation supports have a hollow cavity. The utility model has the advantages that the bus bar ducts alternate with each other using the air as the insulating medium, and each copper bar uses flame-proofed thermoplastic insulating sleeve as the secondary insulation and protection, thereby improving current carrying capacity.
Description
Technical field
The utility model relates to a kind of bus duct, particularly a kind of air type isolated bus groove.
Background technology
The bus duct of producing at home all is a concentration bus duct at present, its advantage is that manufacture craft is convenient, the dynamic stability of short time withstand current peak value is better, but the thermal diffusivity of concentration bus duct is relatively poor, and heating has reduced being subjected to thermal stability and safe carrying capacity easily.Under normal circumstances, the copper bar ampacity of concentration bus duct reduces about 30% than normal copper bar ampacity.So because be intensive higher, because loss and personal injury that the degree of putting off and generate heat of time causes the reduction of wearing out, cause dielectric strength to insulating tape to have an accident and cause property until short circuit to the dielectric strength and the quality requirement that twine insulating tape.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of concentration bus duct in the prior art, and a kind of air type isolated bus groove is provided.The utility model designs a kind of air type isolated bus groove, comprise some copper bars, it is characterized in that: every copper bar is positioned at the caulking groove of a bakelite isolation mount, has bolt to connect between the bakelite isolation mount, is surrounded by the shell steel plate outside the bakelite isolation mount that connects.Every copper bar is with insulation thermoplastic sleeve pipe.There is a nickel coating on every copper bar surface.The bakelite isolation mount has cavity.The utility model has the advantages that bus duct separately from utilizing air to do the medium insulation, every phase copper bar is done two minor insulation and protection with fire-retardant insulation thermoplastic sleeve pipe, improves ampacity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is a copper bar structural representation of the present utility model,
Embodiment
Comprise some copper bars 1 among the figure, it is characterized in that: every copper bar 1 is positioned at the caulking groove 3 of a bakelite isolation mount 2, and is fixedly connected by bolt 4 between the bakelite isolation mount 2, is surrounded by shell steel plate 5 outside the bakelite isolation mount 2 that connects.Every copper bar 1 is with insulation thermoplastic sleeve pipe 6.There is a nickel coating 7 on every copper bar 1 surface.Bakelite isolation mount 2 has cavity.Performance be between the copper bar 1 separately from 20mm, the cavity that utilizes bakelite isolation mount 2 to have 20mm is done air dielectric insulation.Copper bar 1 is done two minor insulation and protection with fire-retardant insulation thermoplastic sleeve pipe 6 again.On every phase copper bar, adopt the hot nickel technical finesse of plating to plate nickel coating 7 in process of production, make it to strengthen electric conductivity and Corrosion Protection, improve ampacity.Connecting two-sided copper coin connection, the contact-making surface at reinforced joint place, raising ampacity, the degree of heat of reduction joint of being close to of median generatrix joint employing plug-in type.High-strength epoxy bakelite isolation mount 2 usefulness high strength insulated bolts 4 are fastening, with mechanical strength, dielectric strength and the short circuit resistance to vibration that improves this product.
