Abstract
The invention relates to a connection fitting for a converter station valve hall. The connection fitting for the converter station valve hall comprises two tubular bus bars which are arranged obliquely or vertically, wherein more than two bent flexible conductors are connected between the two tubular bus bars; the connecting line of the centers of the flexible conductors on the sections, vertical to the extension directions of the flexible conductors, of the bent parts of the flexible conductors is a curve; the flexible conductors distributed at two ends of the curve are called end-part flexible conductors; the flexible conductors distributed between the end-part flexible conductors are called middle flexible conductors; and the diameters of the end-part flexible conductors are greater than those of the middle flexible conductors. According to the skin effect of currents, the currents of the end-part flexible conductors are greater than those of the middle flexible conductors, so that the flexible conductors with relatively large diameters are selected as the end-part flexible conductors; the flexible conductors with relatively small diameters are selected as the middle flexible conductors; the temperature rises of the end-part flexible conductors and the middle flexible conductors are uniform; and over-high temperature rises of the flexible conductors areprevented.
Description
Technical field
The present invention relates to and connect gold utensil field, being specifically related to a kind of converter station valve hall with connecting gold utensil.
Background technology
The converter station valve hall of extra-high voltage DC transmission system is a closed space, has the equipment such as converter valve, bushing shell for transformer, wall bushing, need to connect to form transmitting loop to realize the conversion of AC and DC with pipe bus between distinct device in it.Pipe bus is needed to realize turning in some occasion, now usually by mutually tilting at two or be connected after bending by many flexible conductors between vertically disposed pipe bus.
Such as, Authorization Notice No. is CN201656381U, and name is called that the Chinese patent of pipe bus corner link fitting discloses a kind of pipe bus corner link fitting.Pipe bus corner link fitting comprises two and mutually tilts or vertically disposed pipe buses, and two pipe buses are connected through bending by the flexible conductor of more than many.Such pipe bus corner link fitting is adopted to be easy to realize the turning of pipe bus.But when using pipe bus corner link fitting, it is excessive that flexible conductor always there will be temperature rise.
Excessive in order to solve flexible conductor temperature rise, usually adopt the diameter increasing all flexible conductors.But, so not only can waste material, also correspondingly can increase the diameter of pipe bus, and it be too high still to there will be temperature rise.Through experimental study repeatedly, finally find that wire is pockety in bending place after bending, due to the existence in magnetic field, the size of current of wire pockety is different.
Summary of the invention
The object of the present invention is to provide a kind of converter station valve hall with connecting gold utensil to solve the technical problem that in prior art, flexible conductor temperature rise is too high.
Technical scheme of the present invention: a kind of converter station valve hall is with connecting gold utensil, comprise and mutually tilting or vertically disposed two pipe buses, the flexible conductor of the bending of more than two is connected with between two pipe buses, it is characterized in that: on the cross section of flexible conductor bending place perpendicular to each flexible conductor bearing of trend, the line of centres of each flexible conductor is a curve, the described flexible conductor being distributed in curve two ends is called end flexible conductor, the described flexible conductor be distributed between the flexible conductor of end is called middle part flexible conductor, and the diameter of end flexible conductor is greater than the diameter of described middle part flexible conductor.
Flexible conductor is all uniformly distributed in the end of two pipe buses centered by the center of the end of pipe bus, after flexible conductor bending, be positioned at the flexible conductor that flexible conductor bends the bent angle inner side being and be end flexible conductor, be positioned at flexible conductor bend the outermost flexible conductor of bent angle being be in the middle part of flexible conductor.
Flexible conductor is arranged in pairs.
The quantity of flexible conductor is 10, flexible conductor, is positioned at 4 flexible conductors that flexible conductor bends the bent angle inner side being and is called end flexible conductor, be positioned at flexible conductor bend outermost 6 flexible conductors of the bent angle being be called in the middle part of flexible conductor.
Angle between the length bearing of trend of two pipe buses is 90 degree.
The end of flexible conductor and the end of pipe bus are connected by two complementary mutually semiorbicular armful of folders, embrace folder phase button types for two and are fixed together to hold pipe bus tightly, and the end of flexible conductor is connected mutually with connecting armful to press from both sides.
Usefulness of the present invention: according to the kelvin effect of electric current, the electric current of end flexible conductor is greater than the electric current of middle part flexible conductor, therefore choosing the larger flexible conductor of diameter is end flexible conductor, the flexible conductor that diameter is less is middle part flexible conductor, the temperature rise of end flexible conductor and middle part flexible conductor can be made even, the temperature rise of flexible conductor can not be caused too high.
