As a preferred implementation, said iron core is three post core type cores.
As a preferred implementation, said connector comprises the folder that is positioned at said both sides unshakable in one's determination, and said folder is fixed together said iron core through bolt.
As a preferred implementation, said intermediate insulation body comprises dead ring and cross-over block, the symmetrical at interval both sides up and down that are bonded in said dead ring of said cross-over block.
After having adopted technique scheme, the invention has the beneficial effects as follows:
Because three low pressure windings of suit and two high pressure windings on the core limb, first low pressure winding in every group of low pressure winding is near iron core, and the outside of said first low pressure winding is two high pressure windings; Said two high pressure windings are along the core limb axially-aligned, and said two high pressure windings outside is second, third low pressure winding in every group of low pressure winding, and said second, third low pressure winding is along the core limb axially-aligned; Like this, three low pressure windings can provide two kinds of different capabilities, can connect three loads of two kinds of different capabilities; Three low pressure windings can use separately, also can parallel connection use, when the low pressure winding uses separately; Rectifier transformer can connect three rectifiers of two kinds of different capabilities; Can substitute the logical double winding rectifier transformer of three Daeporis, and have bigger output impedance, the ability of limiting short-circuit current is arranged; When one road commutating circuit is breakdown; Can effectively prevent another road commutating circuit is breakdown to burn out,, can reduce the wastage, improve effect and practice thrift investment and floor space than using the logical transformer of three Daeporis.
Because said connector comprises the folder that is positioned at said both sides unshakable in one's determination, said folder is fixed together said iron core through bolt, so it is fixing to have avoided directly on iron core, holing, does not influence magnetic property.
Because said intermediate insulation body comprises dead ring and cross-over block, the symmetrical at interval both sides up and down that are bonded in said dead ring of said cross-over block so the both sides of cross-over block form the space, help heat radiation and immersion oil.
