Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As Figure 1-3, a kind of low-voltage cable junction box bus-bar system of the utility model, it comprises: the busbar of Switch main body 1 and many parallel equidistant distributions, and described Switch main body 1 is provided with the linkage unit that a row is equally spaced, and multiple described linkage unit and many described busbars connect one to one; Distance between adjacent linkage unit is greater than the distance between adjacent busbar, and at least one linkage unit connects to compensate pitch difference by switching copper bar 4 with corresponding busbar; Many described busbars are all connected with power supply, and described Switch main body 1 is for connecting load.Between busbar and unit, be provided with switching copper bar 4, the linkage unit of different spacing can be connected smoothly with between busbar, achieve the connection of the busbar of same specification and the Switch main body 1 of different size; Do not need to use special adapter, link cost is low.
Concrete, for three-phase circuit, described busbar comprises and setting gradually: A phase busbar 21, B phase busbar 22 and C phase busbar 23, described Switch main body 1 is provided with three linkage units, described A phase busbar 21, C phase busbar 23 are all connected with corresponding linkage unit by switching copper bar 4, and described B phase busbar 22 directly connects with corresponding linkage unit.A phase busbar 21, B phase busbar 22, C phase busbar 23 connect three phase mains respectively, and B phase busbar 22 is directly connected with middle linkage unit, and A phase busbar 21 and C phase busbar 23 are connected to the both sides of B phase busbar 22 respectively by copper bar 4 symmetry of transferring.This is bus structure common in low-voltage cable junction box, and in this structure, two switching copper bar 4 structures are identical, for busbar and the Switch main body 1 of same size model, can produce in batches, directly use; Each Switch main body 1 needs two switching copper bar 4, link cost is low, can extensively promote the use of.
Further, described linkage unit is the connection copper bar 3 with bolt hole, and described busbar is connected with the described copper bar 3 that is connected by bolt, and described connection copper bar 3 is connected with described Switch main body 1.Described switching copper bar 4 is also bolted with corresponding busbar.With bolts, connected mode is simple first, and installation and removal operation is all fairly simple; Second be connected firmly, make Switch main body 1 to be firmly attached on busbar, ensure safety.
Described connection copper bar 3 is connected with load by the fuse be arranged in described Switch main body 1, and when bearing power is too high, fuse is blown, and the connection of load and this busbar disconnects, and prevents busbar damaged, plays the object of protection busbar.
Concrete, the distance between adjacent described busbar is 100mm, and directly can connect 160A bar switch conventional in low-voltage cable junction box, on this bar switch, the spacing of linkage unit is 100mm.Distance between adjacent described linkage unit is 185mm, i.e. the bar switch of more than 160A, and the bar switch of this model also can be used in low-voltage cable junction box, but quantity is few.So low-voltage cable junction box generally adopts spacing to be the busbar of 100mm, when needing the bar switch connecting more than 160A, linkage unit spacing due to bar switch is 185mm, now can adopt bus-bar system described in the utility model, be that the busbar of 100mm is corresponding by the bar switch of more than 160A by switching copper bar 4 and spacing to connect, to compensate pitch difference, realize compatible connection; The utility model is without the need to additionally using special adapter, and link cost is low.
As can be seen from the above embodiments, the utility model compensates by adopting switching copper bar 4, the connection achieving the different Switch main body of spacing 1 and arrange between bus more, and switching copper bar 4 instead of Special adapter, and switching cost is low, can extensively promote the use of; Switching copper bar 4 structure is simple, while guarantee master row insulating distance, has saved copper and insulating material; Relative to Special adapter, the utility model effectively reduces the connection of copper bar, reduces potential faults.The busbar that specification is determined and the connection of bar switch, the size of switching copper bar 4 is determined, can produce in batches, directly use, without the need to customized; Switching copper bar 4 is by bolt and busbar and be connected copper bar 3 and connect, parts difficult drop-off, easy accessibility.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection range of the present utility model.
