Specific implementation mode
As depicted in figs. 1 and 2, a kind of double frame circuit breaker low-voltage cabinets, including cabinet 1 are equipped with main busbar in 1 top of cabinet
3, cabinet 1 is interior to be equipped with several frame circuit breakers 2, and breaker mounting plate 11, supporting beam 12 and mounting hole are further respectively had in cabinet 1
13, frame circuit breaker 2 is mounted on by breaker mounting plate 11 in cabinet 1.21 He of pile crown is respectively equipped on frame circuit breaker 2
Lower pile crown 22, each that the row of connection 41 is above respectively equipped between pile crown 21 and main busbar 3, upper pile crown 21 passes through the row of connection 41 and master
Busbar 3 connects, and outlet row 43 is also associated on main busbar 3, and outlet row 43 is parallel to 41 setting of connection row.Lower pile crown 22 is equipped with
Outlet copper bar 221 is additionally provided with outlet copper bar fixed frame 222 in cabinet 1, and outlet copper bar 221 is set across outlet copper bar fixed frame 222
It sets.Outlet copper bar 221 is connected with L-type row 42, and L-type row 42 extends to 41 outside of connection row around connection row 41, also divides in cabinet 1
Not She You the row's of connection fixed frame and L-type arrange fixed frame, connection row 41 passes through connection row's fixed mount setting, L-type row 42 that L-type is passed through to arrange
Fixed mount setting.It is additionally provided with insulation barrier 31 on cabinet 1 between main busbar 3 and frame circuit breaker 2.Connection row 41, outlet row
43 and L-type row 42 be all made of copper bar.Further, the quantity of frame circuit breaker 2 is at least 2,2 frame circuit breakers 2 it is upper
Pile crown 21 by the 41 main busbars 3 of connection of different connection rows, eliminates side vertical row scheme respectively, solve copper bar dosage compared with
Big problem.
As depicted in figs. 1 and 2, a kind of double frame circuit breaker low-voltage cabinets in use, two frame circuit breakers 2 it is upper
Pile crown 21 is separately connected with main busbar 3, and two frame circuit breakers 2 are to be connect respectively with the main busbar 3 in cabinet top portion, thus may be used
Electricity is taken from main busbar 3 respectively to play each switch, and existing technology is to draw to get off electrification row, electrification row point from main busbar 3
It is not connect with the upper pile crown 21 of switch, draws the sum of the electric current that the row to get off will undertake two switches in this way, lead to current-carrying capacity mistake
Greatly, copper consumption is excessive, and be easy to cause security risk；The outlet copper bar 221 of frame switch 2 arranges 42 sides of being adjusted by L-type
To, facilitate user to connect cable around cabinet rear portion, because being connected to the centre of the copper bar cabinet of main busbar 3 with pile crown 21 on switch,
So switch 22 outlet row of lower pile crown must be by transferring around cabinet rear portion so that the connecting cable of user is convenient；Further
, Normal practice cabinet width only has 600MM wide, and has side row to occupy 200mm in the space of width direction, and user is caused to connect cable
Width there was only 400MM wide, very inconvenient, common practices is all the cabinet with 800mm wide, and since the utility model is hanging down
In line to be placed on centre, the space of 600mm wide is not take up, and after outlet row is extracted, still there is 600mm in the space that user connects cable
Width not only facilitates wiring, and space can be made to be fully utilized, and user can arrange more inside limited power distribution room space
Such switchgear.
Further, simultaneously as the connection row 41 of upper pile crown 21 connect with main busbar 3 and charges for a long time, this practicality is new
Type enables electrification copper bar and user to have a certain distance by way of front and back be staggered, can be electrification by insulation barrier 31
Busbar is isolated, and the safety of cabinet 1 is substantially increased.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
Technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this practicality
Within novel protection domain.
