Technical field
The present invention relates to a kind of transformer, relate in particular to a kind of pressure-adjusting type rectifier transformer.
Background technology
With regard to prior art; So-called transformer is around two or above coil on the iron core of a closure; When a coil feeds AC power (being exactly primary coil), coil midstream is crossed alternating current, and this alternating current produces alternating magnetic field in iron core; The alternation main flux produces the autonomous induction electromotive force in primary coil, simultaneously induction mutual induced EMF in the another one coil (being exactly secondary coil).Change primary and secondary coil-end voltage through the relation that changes primary and secondary coil ratio, realize the conversion of voltage.
Autotransformer is to use under low voltage and is intended for the use of motor reduced-voltage starting at most.For dry-type transformer, its dielectric is the solid of resin and so on, does not have the insulating oil in the oil-filled transformer, so be called dry type.Dry-type transformer is because radiating condition is poor; So capacity can not be done very greatly; Generally has only middle-size and small-size transformer; Electric pressure is also basically at 35KV and following, but now also all had rated voltage to reach 66kV even higher dry-type transformer both at home and abroad, and capacity also can reach 30000kVA even higher.
Simultaneously, autotransformer is output and the special transformer of importing shared one group of coil. boost and realize with different taps with step-down.The part tap voltage of lacking than shared coil just reduces. and the part tap voltage of Duoing than shared coil just raises.Principle is the same with common transformer in fact, and only his primary coil is exactly its secondary coil.General transformer is that the primary coil in the left side passes through electromagnetic induction, makes the secondary coil on the right produce voltage, and autotransformer is that oneself influences oneself.Autotransformer is the transformer that has only a winding, when using as step-down transformer, from winding, extracts a part of wire turn out as secondary winding; When using as step-up transformer, applied voltage only is added on a part of wire turn of winding.Usually call common winding to that part of winding that belongs to simultaneously once with secondary; The remainder of autotransformer is called the series connection winding; Autotransformer with capacity is compared with common transformer, and not only size is little, and efficient is high; And transformer capacity is big more, and voltage is high more. this advantage is just all the more outstanding.Therefore along with the raising of power system development, electric pressure and the increase of transmission capacity, single-circuit transformer is big owing to its capacity, loss is little, cost is low is used widely.
And, adopt the traditional transformer regulating circuit usually, adopt simple autotransformer voltage regulating mode; Its pressure regulation winding is the series coil of autotransformer, is connected to rectifier transformer high pressure winding line end, because of the restriction that receives loaded switch can not be applied to the high voltage system; Generally with 35kV and following; Loaded switch needs the phase-splitting setting, and promptly three-phase rectifier transformer needs three single-phase switchs, and the switch expense is high 3 times.And the total progression of pressure regulation is few, and the level potential difference is big, can not well adapted rectifier transformer user need.
