Abstract
The invention provides a large rectifying equipment connecting device, which comprises connecting bus bars connected between the valve side of a rectifier transformer and the alternating-current sides of rectifiers. The large rectifying equipment connecting device is characterized in that: the connecting bus bars are arranged horizontally in a row, moreover, one end of each connecting bus bar is connected with cophase counter parallel winding valve side bus bars of the rectifier transformer, which are connected as a single phase in a transformer box body, and the other end of each connecting bus bar is connected with alternating-current bus bars of one rectifier, which are of a three-phase bridge type non-cophase counter parallel structure. Consequently, each phase has only two connecting bus bars, and each rectifying unit has twelve connecting bus bars in total; meanwhile, the space between the horizontal bus bars is increased by the single row of horizontally arranged connecting bus bars, as a result, the probability of the short-circuiting between the alternating-current incoming line side bus bars of the rectifiers is decreased, the safety and reliability of operation are enhanced, and the loss of electricity is reduced by one third, so that the efficiency of rectification can be increased; meanwhile, the consumption of copper material is reduced by one half, so investment is saved; the structure is simple, operation is reliable, and the large rectifying equipment connecting device is convenient to install and maintain.
Description
Technical field
The present invention relates to a kind of jockey, especially a kind of device that connects rectifier transformer and rectifier, belong to rectifying installation interconnection technique field.
Background technology
At present, the rectification circuit of Large aluminum electrolytic plant rectifier transformer winding and rectifier all adopts three-phase bridge cophase counter parallel connection mode, and the advantage of this mode is: can make the magnetic field that busbar produces cancel out each other, and vibrate littlely, impedance balance, therefore be widely used.But large rectifier transformer valve side winding cophase counter parallel connection outgoing line busbar spacing is too small, between the cophase counter parallel connection busbar in rectifier, can only rely on again insulating barrier to be separated simultaneously, creepage distance is little, and accident is more, has potential safety hazard.And the rectifier of the horizontal self supporting type rebuilding of single armed cophase counter parallel connection, although security incident is less, rectifier transformer valve side busbar is two-layer layout one on the other, and busbar is longer, loss is larger, copper material consumption is large, must increase investment, and ac bus is 4 of every phases in addition, totally 24, every rectifier, complex structure not only, the useful space is narrow and small, and installation, maintenance difficulties are larger.Therefore, be necessary prior art is improved.
Summary of the invention
The problems referred to above that exist for solving prior art, the invention provides a kind of large-scale rectifying installation jockey.
The present invention completes by following technical proposal: a kind of large-scale rectifying installation jockey, comprise the busbar that is connected connected between rectifier transformer valve side and rectifier AC, it is characterized in that described connection busbar is single horizontal, and an end of this connection busbar with connect into single-phase rectifier transformer cophase counter parallel connection winding valve side busbar be connected in transformer-cabinet, the other end is connected with the alternating current bus bar of the non-cophase counter parallel connection structure of rectifier three-phase bridge.
Described connection busbar comprises the short busbar be connected with rectifier transformer valve side busbar, the long busbar be connected with rectifier AC busbar is provided with soft bus between short busbar and long busbar, effectively vibration damping, complete temperature compensation, the error existed when abatement apparatus is installed.
Described short busbar at least arranges two, on the short busbar of each piece, establishes through hole, establishes bolt and nut in through hole, to facilitate with rectifier transformer valve side busbar, closely is connected.
The described long busbar other end is established through hole, establishes bolt and nut in through hole, to facilitate with the rectifier alternating current bus bar, is connected.
Two of the every phases of described connection busbar, totally ten two of every Rectification Power Factor.
Spacing between described single horizontal connection busbar is 550～650mm, increases the alternate spacing of horizontal busbar, improves the security reliability of operation.
Described connection busbar surface scribbles coating, to prevent from connecting busbar oxidation and maintenance metallic luster.
The present invention has following advantages and effect: adopt such scheme, make to connect the every phase of busbar and be only 2, totally 12 of every Rectification Power Factor, connect busbar adopts single horizontal simultaneously, increased the alternate spacing of horizontal busbar, greatly reduce rectifier and exchange the possibility be short-circuited between inlet wire side busbar, increased the security reliability of operation, and make busbar length reduce 1/3, electric energy loss reduces 1/3, to low-voltage, the short net of large electric current, the minimizing of bus length is significant, contribute to the raising of rectification efficiency, reduce copper material consumption 1/2 simultaneously, greatly saved investment.The present invention is simple in structure, reliable, installation, easy to maintenance.
