Abstract
The invention discloses a high-speed railway transformer with a Dzn0 connecting structure. The transformer comprises a magnetic core and a coil wrapped on an outer wall of the magnetic core, wherein the connecting mode of the coil is Dzn0 connection. Because the coil of the transformer adopts a Dzn0 connecting mode, primary and secondary lateral line voltage phases of the transformer are ensured to be consistent (the phase difference is 0 degree), a phase-angle difference cannot appear during switching or bypass isolation transformation, and then the efficiency of the transformer and the stability of online communication can be ensured.
Description
Technical field
The present invention relates to a kind of transformer, high ferro is used transformer specifically.
Background technology
Transformer (Transformer) is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).In electric equipment and radio-circuit, up-down voltage, the matched impedance done commonly used, safety isolation etc.General transformer adopting be the Dyn11 connected mode; Such connected mode can not guarantee transformer one secondary side line voltage-phase consistent (phase difference is 0 degree); Phase angle difference can appear in switch like this or bypass isolated variable etc., and phase angle difference can directly influence the stability of transformer efficiency and online communication.
Summary of the invention
The objective of the invention is the deficiency that exists to prior art, provide a kind of can guarantee transformer efficiency and again the high ferro of the stability of row communication use transformer.
For realizing the foregoing invention purpose, the technical scheme that the present invention adopts is that a kind of high ferro of the Dzn0 of having syndeton is used transformer, comprises magnetic core and wrapped coil at the magnetic core outer wall, and the connected mode of said coil is that Dzn0 connects.
Elementary first winding, second winding and the 3rd winding of comprising of said coil, secondary the 4th winding, the 5th winding, the 6th winding, the 7th winding, the 8th winding and the 9th winding of comprising of said coil; One end of said first winding and an end of second winding join, and an end of the other end of second winding and the 3rd winding joins, and the other end of the other end of the 3rd winding and first winding joins; One end of said the 4th winding and an end of the 7th winding join; One end of the 5th winding and an end of the 8th winding join; The other end of the other end of the 7th winding and the 8th winding all joins with an end of the 9th winding, and an end of the 9th winding and an end of the 6th winding join.
Beneficial effect: coil of the present invention is owing to adopted the connected mode of Dzn0; So can guarantee transformer one secondary side line voltage-phase consistent (phase difference is 0 degree); When switching or bypass isolation change, phase angle difference be can not occur, the efficient of transformer and the stability of online communication so just can be guaranteed.
