Abstract
The utility model discloses a kind of new bus duct tapping unit, it includes the tap mouth insulating base being arranged on the bus slot cover board, tap mouth is provided with the tap mouth insulating base, the tap mouth copper pile crown drawn from bus duct main line element solder passes through the tap mouth.The tap mouth insulating base is fixed on bus slot cover board by four self-tapping screws.The utility model draws tap mouth copper pile crown by using welding manner, the contact resistance of point interface is completely eliminated the fever phenomenon of tradition tap mouth close to zero, is extended the service life of bus duct, ensure that bus duct long-term safety is run.
Description
Technical field
Bus duct technical field is the utility model is related to, specially a kind of new bus duct tapping unit.
Background technology
With the development of society, modern high-rise building and large-scale workshop need huge electric energy, hundreds and thousands of peaces can be transmitted
Train powerful electric current, and in the line between reserve tap mouth in order to which the bus duct of power taking on the spot is widely applied.Latest model
Bus duct is the conductor outer wrapping insulating materials using high-purity copper bar as conductor, then the high strength sectional material drawn with almag is made
Shell, by three phase lines row (ABC phases are arranged) in electrical voltage system, a zero-emission (N rows), ground protection row (PE rows) combination
The power distribution equipment for the efficient conveying electric current being assembled into.
It is known that in order to eliminate the influence of conductor kelvin effect, conductor copper bar must make flat thin rectangle shape as far as possible
Shape, therefore traditional bus duct tapping unit uses plug-in type way to take power：Design splayed configuration and insert pawl as moving contact, it is fixed
In on electrifying box.When needing power taking on the spot, in the tap mouth that will be reserved on the slotting pawl insertion bus duct main line unit on electrifying box,
The flat thin trunk copper bar insertion splayed configuration of bus duct main line unit is set to insert in pawl, similar to the contact of dynamic/static contact in chopper switch
Mode.But due to bus duct structure space very little, splayed configuration inserts pawl can only add steel spring piece to increase copper pawl on the outside of two panels copper pawl
To the pressure of trunk copper bar, to reach the purpose for reducing contact resistance, because of the limited pressure of steel spring piece, therefore splicing position is because of contact
Resistance is big and generates heat substantially, shortens the life-span of insulating materials, have impact on the long-term safety operation of bus duct.How tap is reduced
The contact resistance of mouth splicing position or the way to take power for changing tap mouth, are always the problem that bus duct manufacturing need to solve.
Utility model content
The purpose of this utility model is to provide a kind of new bus duct tapping unit, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of new bus duct tapping unit, its
Including the tap mouth insulating base being arranged on the bus slot cover board, tap mouth is provided with the tap mouth insulating base, from mother
The tap mouth copper pile crown that wire casing main line element solder is drawn passes through the tap mouth.
Further, tap mouth insulation flap with matching is provided with the tap mouth insulating base.
Further, the tap mouth insulating base is that DMC moulds material or ambroin make.
Further, the sectional dimension of the tap mouth copper pile crown is 3mm × 40mm.
Further, the tap mouth insulating base is fixed on bus slot cover board by four self-tapping screws.
Compared with prior art, the beneficial effects of the utility model are：The utility model draws tap using welding manner
Mouth copper pile crown, the contact resistance of point interface is set to completely eliminate the fever phenomenon of tradition tap mouth close to zero, extend mother
The service life of wire casing, it ensure that bus duct long-term safety is run.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model taps mouth insulating base；
Fig. 3 is the structural representation for tapping mouth insulation flap.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of new bus duct tapping unit, it is wrapped
The tap mouth insulating base 1 being arranged on the bus slot cover board 6 is included, tap mouth 7 is provided with the tap mouth insulating base 1, from
The tap mouth copper pile crown 2 that the welding of bus duct main line unit 5 is drawn taps mouth 7 through described.
In the present embodiment, tap mouth insulation flap 4 with matching is provided with the tap mouth insulating base 1.
In the present embodiment, the tap mouth insulating base 1 is that DMC moulds material or ambroin make.
In the present embodiment, the sectional dimension of the tap mouth copper pile crown 2 is 3mm × 40mm.
In the present embodiment, the tap mouth insulating base 1 is fixed on bus slot cover board 6 by four self-tapping screws 3.
Operation principle：It is pre- by design size welding on the trunk copper bar of bus duct main line unit 5 before assembling bus duct
Then each parts of bus duct are traditionally riveted molding assembly by the tap mouth copper pile crown 2 first processed, in tap mouth copper
Tap mouth insulating base 1 is put at pile crown 2, will divide interface each phase copper pile crown mutually insulated, then covers tap mouth insulation flap.
When needing power taking on the spot, tap mouth insulation flap is opened, electrifying box is installed, each pile crown will be switched in electrifying box with dividing interface each
Phase copper pile crown is connected with wire is corresponding, so that by electric energy by bus duct main line unit transportation to electrifying box, then be transported to electricity consumption and set
It is standby.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
