Description
Technical field
The present invention relates to a kind of method and device that accessory power supply is produced using transformer body, belong to oil-immersed type power
Transformer controls and the power supply technique field of auxiliary equipment.
Background technology
It is well known that oil-immersed power transformer is in the process of running, in order to can in real time, monitor transformer
Operation conditions, ensure transformer safety, stably run.Control and auxiliary equipment just must have stable and reliably supply
Electric source.The supply voltage of control and auxiliary equipment access is relatively low, domestic generally exchange 380V.In order to obtain the voltage
The power supply of grade, it is common practice to, individually designed powersupply system, to control and auxiliary equipment power supply.
The defects of this design method is individually designed power supply loop, fail to utilize very well transformer its own
Resource.Especially for portable oil-immersed power transformer, because individually designed power supply loop is more troublesome, this
Kind defect just becomes apparent.
The content of the invention
Problem to be solved by this invention is how to make transformer coil obtain sufficiently effectively utilizing, and be can guarantee that simultaneously
The stabilization of control and auxiliary equipment power supply and reliable.
Technical scheme is used by the present invention solves above-mentioned technical problem：One kind produces auxiliary using transformer body
The method of power supply, it is characterised in that the coiling assists winding on transformer core, using electromagnetic induction principle, induce required
Control voltage, control voltage leads to auxiliary sleeve pipe by lead, and auxiliary sleeve pipe passes through cable connection assists winding；Auxiliary around
Group controls the interface of power supply by cable connection, so as to be needed auxiliary equipment and control device directly to power.
Present invention also offers a kind of device that accessory power supply is produced using transformer body, the iron core of the transformer
Outside is wound with low pressure winding, high pressure winding, tap-changing windings successively from the inside to the outside, it is characterised in that in the transformer core
Outside is also wound with the assists winding of more numbers of turn for induced control voltage, and the coil of assists winding is more by lead connection
Individual auxiliary sleeve pipe, auxiliary sleeve pipe, which is arranged in order, to be fixed in fuel tank sidewall.
The present invention is in oil-filled transformer coil inside, first coiling ancillary coil, then draws ancillary coil with lead,
Clamped and anchor leg by wooden piece, led to afterwards with sleeve pipe on auxiliary transformer, then be connected to control and auxiliary equipment
On power supply loop, so as to reach the purpose to control and auxiliary equipment power supply.
The principles of science of foundation of the present invention is：Transformer is that the static transmission according to made by electromagnetic induction principle is handed over
Stream electric energy simultaneously changes the device of alternating voltage.Using this principle, specific voltage can be induced to be set to control and auxiliary
Available electricity.
In the oil-immersed power transformer running of the present invention, the control power supply in control and auxiliary equipment loop need not
It is individually designed again, transformer own resource can be made full use of completely, realize integration.
Brief description of the drawings
Fig. 1 is the coil layout figure for the oil-immersed type power two-winding transformer that embodiment provides；
Fig. 2 is the connection diagram of ancillary coil and auxiliary sleeve pipe that embodiment provides.
Embodiment
To become apparent the present invention, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in Figure 1, 2, a kind of device that accessory power supply is produced using transformer body provided for the present embodiment, it is described
The outside of iron core 4 of transformer is wound with low pressure winding 3, high pressure winding 2, tap-changing windings 1 successively from the inside to the outside, it is characterised in that
The assists winding 5 of more numbers of turn for induced control voltage is also wound with the outside of the transformer core, in assists winding 5
One circle is an ancillary coil 8, assists winding 8 by lead 9 and corresponding auxiliary sleeve pipe 6 connect through lead 8 connect it is multiple
Sleeve pipe 6 is aided in, auxiliary sleeve pipe 6, which is arranged in order, to be fixed in the side wall of fuel tank 7.
In fig. 2, after the coiling of coil 8 of assists winding 5.Head end is respectively adopted lead 4 and leads to auxiliary sleeve pipe 1, draws three spiders
Pipe, respectively A phases, B phases and C phases；End links together, then leads to auxiliary sleeve pipe 1, draws a branch casing, is neutral point N.
When lead needs to fix, it can be gripped using wooden piece.
Sleeve pipe 6 is aided in typically to use the sleeve pipe of low-voltage-grade.After coil 8 is connected to auxiliary sleeve pipe 6 by lead 9, Ke Yitong
Cross at cable connection auxiliary sleeve pipe 6 to auxiliary transformer.Auxiliary transformer is placed in a single cupboard, cupboard peace
On transformer box wall.Finally, the interface with cable connection auxiliary transformer and with control power supply, then needed alternating current
Auxiliary equipment and the control device power supply in source.
Method is specially：The coiling assists winding 5 on transformer core, using electromagnetic induction principle, induce required control
Voltage, control voltage lead to auxiliary sleeve pipe 6 by lead 9, and auxiliary sleeve pipe 6 passes through cable connection assists winding 5；Assists winding 5
The interface of power supply is controlled by cable connection, so as to be needed auxiliary equipment and control device directly to power.
