Abstract
The hard bus of the short net of big electric current, belong to conducting system equipment, comprise the copper coin bus, laterally offer some through holes in the copper coin bus, be used to walk cooling water, intensity of cooling is big, avoid simple copper coin by low overheated thawing, the obscission that causes of air cooling intensity, can make copper coin bus surface add insulating barrier simultaneously, guaranteed the insulativity between each copper coin, greatly reduced equipment failure rate, have the power factor height, impedance, induction reactance are little, and loss is little, advantages such as current density is medium, and reliable, cost of investment is few.
Description
Technical field
The utility model belongs to conducting system equipment, refers in particular to the hard bus of the short net of big electric current that is applied in the hot stove conducting system in ore deposit, promptly is to the part (being commonly called as hard bus) between the soft bus from the transformer secondary outlet.
Background technology
The existing ore deposit short net of the big electric current of hot stove mainly contains two kinds on the short net of copper pipe and the short net of copper bar, the hard bus of the short net of copper pipe is made of the insulating barrier of interior copper pipe bus with the periphery, walk cooling water in the copper pipe, intensity of cooling is high and invest for a short time, reliable, and deficiency is that current density is big, impedance, induction reactance are big, cause the reactive power of short net big, power factor is low, and loss is big; The hard bus of the short net of copper bar is that simple copper coin is lined up, relatively its current density of copper pipe pipe network is little, impedance, induction reactance is little, the power factor height, and loss is little, deficiency is to rely on the air between copper bar to cool off, intensity is low, and because of the ambient temperature height, copper bar is increased by thermal resistance, each copper coin heating can cause melting, in addition, each copper coin surface can't be provided with insulating barrier, dust in air, suspended matter easily is adsorbed in the copper coin surface, cause on-insulated between copper coin, moreover copper coin working temperature height, when the excoriation of copper bar oxide on surface, it is easily breakdown that resistance reduces copper bar, above-mentioned reason makes the failure rate height of the hard bus of copper bar class, and its investment is also big.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, provide a kind of investment less, the power factor height, impedance, induction reactance is little, loss is little, current density is medium, reliable, the hard bus of the short net of the big electric current that intensity of cooling is high, its innovation part is the advantage in conjunction with two kinds of background technologies, to be built-in with some through holes of laterally offering as the copper coin of bus, these through holes are used to walk cooling water, realize quick heat extraction, and the copper bar outer surface that cooling is resolved just can be provided with insulating barrier, the problem that the failure rate of avoiding simple copper bar to bring is high, specifically be achieved like this: the hard bus of the short net of big electric current, comprise the copper coin bus, it is characterized in that laterally offering in the copper coin bus some through holes.Through hole can be one, places top or bottom or middle any position of copper coin bus, can be two also, is equipped with the two ends or a single-ended and middle arbitrary position of copper coin bus, also can be that it can be undetermined according to actual conditions more than three or three.
The copper coin bus periphery of band through hole of the present utility model is equipped with insulating barrier, add insulating barrier and effectively guaranteed insulation fully between each copper coin, avoided the absorption of air plankton, also do not had the copper coin oxide on surface cortex problem that comes off, solved failure rate on the copper coin surface.
The utility model is by offering away the cooling water through hole in copper coin bus inside, intensity of cooling is big, avoid simple copper coin by low overheated thawing, the obscission that causes of air cooling intensity, can make copper coin bus surface add insulating barrier simultaneously, guaranteed the insulativity between each copper coin, greatly reduced equipment failure rate, have the power factor height, impedance, induction reactance are little, and loss is little, advantages such as current density is medium, and reliable, cost of investment is few.

Embodiment
Embodiment 1, the hard bus of the short net of big electric current, and bus adopts the copper coin form, laterally is equipped with two through holes 2 in the copper coin bus 1, lays respectively at the top and the place, bottom of copper coin bus, and copper coin bus 1 periphery of band through hole 2 is equipped with insulating barrier 3.
Embodiment 2, reference example 1, and the through hole setting in the copper coin bus can be one, is positioned at the arbitrary position in top or bottom or middle part of bus, also can be more than two or two, determines that according to actual conditions the position also can be selected arbitrarily as required.
Claims (4)
1. the hard bus of the short net of big electric current comprises the copper coin bus, it is characterized in that laterally offering in the copper coin bus some through holes.
2. the hard bus of the short net of big electric current according to claim 1 is characterized in that through hole has one, more than two or two.
3. the hard bus of the short net of big electric current according to claim 1 and 2 is characterized in that through hole places the arbitrary position in top and/or bottom and/or middle part of copper coin.
4. the hard bus of the short net of big electric current according to claim 1 is characterized in that being equipped with insulating barrier with the copper coin bus periphery of through hole.
