Description
Technical field
The utility model relates to the air switch field, more particularly, relates to a kind of air switch busbar.
Background technology
Between the air switch and the mode that connects mainly contain following several: first kind of mode as shown in Figure 1, air switch input row 20 is fixed on the bus-bar 30 by trip bolt, and then inserts air switch 10.This mode causes many faying surfaces between bus-bar 30 and the air switch input row 20, and each input row 20 needs a trip bolt to fix, and causes cost to increase.This in addition connected mode can't realize versatility, and bus-bar need be made according to different demands.
The second way as shown in Figures 2 and 3, used busbar 40 is to go out the input row who is used to insert air switch 10 on copper bar or aluminium row, operate the handle 50 of air switch below for convenience, busbar can be held the top bending to sky, causes the outward appearance of busbar relatively poor like this.And in order to meet the requirements of ampacity, the size of this busbar is all bigger, takies the space of rack.Owing to there is not to connect the place of cable on the busbar, if directly perforate connects cable on busbar, also can take rack space up and down, this is difficult to realize concerning the rack of space anxiety, common way is that the input row of cable 60 and busbar 40 receives on the air switch together, the electric current that can cause this input current drainage like this is exactly the electric current on the whole piece busbar, causes this input row's temperature rise very high, can't satisfy instructions for use.The quantity of air switch can determine according to actual needs, and busbar can on-the-spot as required cutting, and this can cause installation work-hour waste and cost increase.
The used busbar of the used busbar of the third mode and the second way is the same substantially, just increases the insulation protection housing, makes in the alternating current occasion safer.There are problems such as input row temperature rise is too high, cut out at the scene too in this busbar.
The label of the air switch of representing each road in above-mentioned several mode, all is not provided for the place of adhesive label on the used busbar, in order to be attached on the air switch, damage at air switch, under the situation of the air switch that more renews, can't identify again, cause entanglement easily, be difficult for identification.
Copper is as a kind of important common metal in addition, and price is relatively more expensive.On same cross-sectional was long-pending, the ampacity of aluminium was about 0.8 times of copper, but the proportion of aluminium is 2.7g/cm
3, the proportion of copper is 8.92.7g/cm
3, the proportion of aluminium is about 1/3 times of proportion of copper, and the price of market aluminium also is about 1/3 times of copper, that is to say, reach same ampacity, adopts aluminium, and cost can be cheap a lot.
