Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1 with shown in Fig. 2, a kind of Medium Voltage Switchgear bus connecting device, is specifically combined by the first iron core 1, second iron core 1 ', connection copper clamping plate 4, first spring coil 3, second spring coil 3 ' and limited bolt 6.First iron core 1 and the second iron core 1 ' surface all scribble insulating coating 2, and such first iron core 1 and the second iron core 1 ' and the first spring coil 3 and the second spring coil 3 ' have just insulated better; Described connection copper clamping plate 4 are provided with right hole 5, left hole 5 ' and spacing hole 6 ', fix wherein for the first iron core 1, second iron core 1 ', limited bolt 6; First spring coil 3 and the second spring coil 3 ' are respectively equipped with the first spring coil free end 7, second spring coil free end 7 ' and the first spring coil link 8, second spring coil link 8 ', first spring coil 3 and the second spring coil 3 ' surface all scribble insulating coating, are not energized when use with the first iron core 1 and the second iron core 1 '.During use, need two pieces to connect copper clip board engagement and use clamp rectangular bus.
Particularly, the first iron core 1 and the second iron core 1 ' insert and in the right hole 5 being fixed on described connection copper clamping plate 4 and left hole 5 ' respectively; Be wrapped on the first iron core 1 by first spring coil 3, the free end 7 of the first spring coil 3 is contacted with connection copper clamping plate 4, and link 8 is connected with the second spring coil 3 ' link 8 ';
Then, the second spring coil 3 is wrapped on the second iron core 1 ', and contacted with connection copper clamping plate 4 by the free end 7 ' of the second spring coil 3 ', link 8 ' first spring coil link 8 connects; Such first spring coil 3 has just been communicated with by two spring links with the second spring coil 3 '.
Finally, get two pieces and insert iron cores and winding spring coil connects copper clamping plate 4 on iron core, by limited bolt 6 through the spacing hole 6 ' connecting copper clamping plate 4, rectangular copper bus-bar waiting is fixed between two pieces of identical connection copper clamping plate 4, such rectangular copper bus-bar just by these two pieces connect copper clamping plate 4 clamp and fixing together.
In order to fix bus better, the first iron core 1 and the second iron core 1 ' quantity are 2, and correspondingly, the right hole 5 and the left hole 5 ' quantity that connect copper clamping plate 4 are also 2, and such rectangular copper bus-bar is just clamped better by these two pieces connection copper clamping plate 4 and fixes together
As shown in Figure 2, the copper busbar 9 of I cabinet rectangle and the copper busbar 9 ' of II cabinet rectangle are respectively the bus of two independently switch cubicles, only need by two buses fech connection device respectively during connection, when cabinet bus does not have electric current through out-of-date, rectangular bus bar is clamped by the elastic force of limited bolt 6 and the first spring coil 3 and the second spring coil 3 ' by jockey, makes two pieces to connect copper clamping plate 4 and links together with the copper busbar 9 of I cabinet rectangle and the copper busbar 9 ' of II cabinet rectangle.
Certainly, can On current, when there being electric current to flow through bus, because of the first spring coil 3 and the second spring coil 3 ' free end all be connected copper coin and contact, the effect of shunting can be produced, portion of electrical current is had to flow to C point by the free end A point of spring coil 3 through B point, the electric current flowing through spring coil can make iron core band be magnetic because of galvanomagnetic effect, the magnetic pole of upper and lower two corresponding iron cores is contrary, one is N pole, one is S pole, pulling force is produced because the two poles of the earth attract each other, make two iron cores further to copper busbar central motion, thus compression two spring coil produces elastic force, elastic force makes to connect copper clamping plate and is pressed on better on bus.The electric current of flow bus is larger, and its magnetic force produced is larger, and the elastic force that spring produces is also larger, and the connection of bus is also more reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
