According to the double-split rectifier transformer with the field coils and the tandem primary side coils, due to the fact that magnetic field influence between the two device body sets is almost zero, two paths of output on valve sides cannot interfere with each other; due to the fact that the network side coils are of a tandem structure, circular current among the coils is avoided, and loss is reduced.
Description
Technical field
The present invention relates to transformer technology field, particularly a kind of two division rectifier transformers of the series connection of the first siding ring with magnet exciting coil.
Background technology
Division rectifier transformer is mainly used in powering to rectifier transformer.Domestic traditional division rectifier transformer exists current harmonics and suppresses undesirable, and primary side exists the shortcomings such as circulation, so proposed two division rectifier transformers of first siding ring series connection.This transformer is divided into two groups of device bodies.Every group of device body comprises independently iron core, first siding ring, second siding ring.But this structure has been brought again new problem: 1, between two groups, voltage is difficult to control; When 2, transformer partly passes through operation, transformer exists serious ampere-turn uneven.
Summary of the invention
For addressing the above problem, the object of this invention is to provide a kind of two division rectifier transformers of the series connection of the first siding ring with magnet exciting coil.
The present invention adopts following scheme to realize: a kind of two division rectifier transformers of the series connection of the first siding ring with magnet exciting coil, is characterized in that: comprise a fuel tank and first group of device body and the second group of device body in this fuel tank in tandem; The iron core of first and second described group device body adopts three-phase three-limb structure, independent separately between three-phase; Every phase device body is from iron core arrangement of valves lateral coil, magnet exciting coil, net lateral coil successively outward;
Wherein, the valve lateral coil number of turn of described second group of device body is 1.73 times of the valve lateral coil number of turn of first group of device body; Between the valve lateral coil of described first group of device body, adopt Y knot, adopt D knot between the valve lateral coil of second group of device body, the voltage and current numerical value of output equates, differs 30 ° in phase place; The magnet exciting coil of the corresponding phase of first group of device body and second group of device body is in parallel, then by one point earth wherein; The net lateral coil of the corresponding phase of described the first device body and the second device body is cascaded mutually, and the end of the three-phase coil of the second device body is bound up, the whole Y knot that forms.
In an embodiment of the present invention, the core section of first and second described group device body is identical, is from left to right arranging A, B, C three-phase.
In an embodiment of the present invention, structural capacity and the calculated capacity of described first and second group device body equate.
In an embodiment of the present invention, on described net lateral coil, be all furnished with the tap changer of identical range of regulation.
In an embodiment of the present invention, described pressure regulation adopts non-excitation pressure adjustment or on-load voltage regulation.
In an embodiment of the present invention, each net lateral coil of described first and second group device body is identical with the structure of magnet exciting coil.
The invention has the beneficial effects as follows: 1. the influence of magnetic field between liang group device body is almost nil, can phase mutual interference between the two-way output of valve side.2. net lateral coil adopts cascaded structure, has avoided the circulation between coil, has reduced loss.3. the voltage regulating mode on net lateral coil is identical, during pressure regulation, synchronously carries out, and has guaranteed the operation equal turn numbers of two coils.4. due in parallel between magnet exciting coil, between two groups, voltage equates, thereby has guaranteed that between two windings of net side, voltage equates, thereby valve side output voltage values equates.5. when two groups of output capacities of valve side are unequal, when even transformer partly passes through operation, magnet exciting coil can produce circulation, has guaranteed all ampere-turn equilibriums of every group of device body.6. magnet exciting coil single-point grounding, has avoided the floating potential of coil, and can gauze screen lateral coil and valve lateral coil between high order electromagnetic wave.
