China Patent Publication No.: CN102568780AA, open day on July 11st, 2012, a kind of transformer lead syndeton is disclosed, comprise the first joint, the second joint and winding protruding head lead-in wire, wired nose is welded in winding protruding head lead-in wire upper end, the second joint is three-way shape, the second joint is an end and the second copper pipe wire bonds wherein, another two ends are bolted with the first joint and line nose respectively, the other end of the first joint and the first copper pipe wire bonds, the connecting portion of above-mentioned each parts does not justify or groove is filled with crimped paper, the periphery of above-mentioned each parts is enclosed with aluminium platinum crimped paper from inside to outside successively, crimped paper and high Netowrk tape.But it is larger that this technical scheme still has volume, structure is not compact, and adjustable range is little, noise is large, unstable properties, the problem of not energy-conservation not environmental protection.
The utility model content
The purpose of this utility model is to exist volume larger for solving current technical scheme, and structure is not compact, and adjustable range is little, noise is large, unstable properties, and the problem of not energy-conservation not environmental protection, provide a kind of pin configuration of frequency control oil immersed type rectifier transformer.
The utility model solves the technical scheme that its technical problem adopts: a kind of pin configuration of frequency control oil immersed type rectifier transformer, comprise transformer body, also comprise valve side winding, bracing frame, cable, wire clamp and low-voltage wiring terminal box, lifting one's head of described valve side winding is connected with the input of cable, the output of described cable is connected with the low-voltage wiring terminal box, described bracing frame one end is fixed on transformer body, the other end of support frame as described above is connected with cable by wire clamp, and described valve side winding is two cake formula structures.The electric current of the leading-out end of each joint group is at the hundreds of ampere like this, be convenient to high-pressure side one and discharge the lead-in wire selection of head and low-pressure side one discharge head, be conducive to reduce three-phase dc resistance unbalance rate, be conducive to reduce the distance of lead-in wire to fuel tank, reduce the stray loss of transformer.
As preferably, described valve side winding is two cake formula structures, and every a pair of cake formula valve side winding connects the winding formation that is staggered by star connection, Y connection winding and dihedral.
As preferably, described cable is the paper bag copper cable, and each group two lifting one's head of pie winding draw by cable.The selection of paper bag copper cable, be conducive to reduce three-phase dc resistance unbalance rate, if one have 36 joint group, and those every side one each 18 joint group of row, the D.C. resistance unbalance factor between every group will all be less than 2%.
As preferably, described wire clamp is connected by the bolt group with described bracing frame.In manufacture, transportation, running, do not relatively move, good stability.
As preferably, be welded with the connection terminal on the output of described cable, described connection terminal is connected with described low-voltage wiring terminal box.Arrange like this, be convenient to and the connecting of low-voltage wiring terminal box, because of every group the lead-in wire electric current very little, what the low-voltage wiring terminal box can be done like this is very little, can do two groups of line banks in each box, thereby be arranged in the sidewall of fuel tank, it is supporting with it that frequency converter also can be made many groups like this, thereby reach material-saving, energy-conservation purpose.
