Abstract
The invention discloses a kind of method for tackling transformer current increase, its step are as follows：S1：Transformer is chosen：Easily there is the transformer loaded in rural area；S2：Coil：Increase by one group of coil winding in transformer；S3：Mix well tap changer：One, which is installed, in the overall coil port of transformer mixes well tap changer；S4：Current transformer：End is flowed into the electric current of transformer and connects a current transformer, is then connected current transformer with mixing well the control system of tap changer, and the present invention has the advantages that to reduce loss, reduces heat production.
Description
Technical field
The present invention relates to a kind of implantation methods, are specifically related to a kind of method for tackling transformer current increase.
Background technology
Transformer（Transformer）It is the device for changing alternating voltage using the principle of electromagnetic induction, main member
It is primary coil, secondary coil and iron core（Magnetic core）.Major function has：Voltage transformation, current transformation, impedance are converted, isolated, be steady
Pressure（Magnetic saturation transformer）Deng.It can be divided into, according to use,：Power transformer and special transformer（Electric furnace change, rectification change, power frequency examination
Test transformer, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformation
Device, electronic transformer, reactor, transformer etc..
Belong to peak times of power consumption to eight at night in the rural area every dusk, now transformer at this moment can overload operation,
Therefore the electric current increase of transformer coil, caused heat, which increases, will damage transformer, and traditional radiating mode is typically all
Increase radiating effect, but this can not fundamentally solve the problems, such as to produce heat.
The content of the invention
In view of the above the shortcomings that prior art, it is an object of the invention to provide one kind reply transformer current increase
Method, for solve the problems, such as radiating mode of the prior art can not fundamentally solve caused by a large amount of heat energy.
In order to achieve the above objects and other related objects, the invention discloses a kind of side for tackling transformer current increase
Method, its step are as follows：
S1：Transformer is chosen：Easily there is the transformer loaded in rural area；
S2：Coil：Increase by one group of coil winding in transformer；
S3：Mix well tap changer：One, which is installed, in the overall coil port of transformer mixes well tap changer；
S4：Current transformer：End is flowed into the electric current of transformer and connects a current transformer, then by current transformer with adjusting
The even control system connection to compress switch.
Further：Described tap changer of mixing well is motor switch.
As described above, beneficial effects of the present invention：When transformer load, electric current becomes big, when electric current exceedes current inductor
During setting value, tap changer tripping operation is mixed well, by increased coil come shunt current, is lost with this to reduce caused by load.
Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
In order to achieve the above objects and other related objects, the invention discloses a kind of side for tackling transformer current increase
Method, its step are as follows：
S1：Transformer is chosen：Easily there is the transformer loaded in rural area；
S2：Coil：Increase by one group of coil winding in transformer；
S3：Mix well tap changer：One, which is installed, in the overall coil port of transformer mixes well tap changer；
S4：Current transformer：End is flowed into the electric current of transformer and connects a current transformer, then by current transformer with adjusting
The even control system connection to compress switch.
Further：Described tap changer of mixing well is motor switch.
Finally it should be noted that：Above example only not limits technology described in the invention to illustrate the present invention
Scheme；Therefore, although this specification with reference to above-mentioned each embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent substitution；And all do not depart from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
