Description
Technical field
The present invention relates to transformer technology fields, more specifically, being related to a kind of vacuum oil-filter and transformer dc is inclined
The processing method of magnetic.
Background technique
Transformer DC magnetic bias phenomenon refers to: DC current is flowed into the winding of power transformer by neutral point,
There is DC component in the exciting current of transformer, so that transformer be made to be in abnormal operating state.
D.C. magnetic biasing endangers transformer bring are as follows: 1, noise increase, the noise of substation are mainly sent out by transformer
Out, several times or tens times when transformer noise decibel can achieve normal operation when D.C. magnetic biasing.D.C. magnetic biasing will lead to
Transformer noise increases, and making transformer noise is more than specified value, to not meet the requirement of environmental protection.2, vibration aggravation becomes
The problem of depressor vibration aggravation, increases serious more than noise.Strong vibration will lead to the loosening of transformer related components, cause
Electric heating, electric discharge or components fall off, so that the safe operation to transformer constitutes serious threat, and then jeopardize the peace of power grid
Row for the national games.3, hot-spot and temperature rise, temperature rise caused by D.C. magnetic biasing can have an adverse effect to transformer station high-voltage side bus, to sum up
It is main to indicate in the following aspects: (1) to cause power transformer interior fault.Transformer winding conducting wire, oil tank wall, iron-core draw-board or
The structural members such as support plate are all made of metal material, and metal material temperature is excessively high, and rigid can reduce, and even result in metal
Material structure deformation, to cause power transformer interior fault.(2) insulation ag(e)ing for accelerating transformer shortens transformer and uses the longevity
Life.(3) gas content in transformer oil is caused to increase.When transformer is in normal operation, due to its insulation ag(e)ing, transformation
Device oil and SOLID ORGANIC insulating materials can decomposite a small amount of hydrocarbon, carbon monoxide and carbon dioxide, these gases largely dissolve
In transformer oil.When gas reaches certain amount, will some gas enter in Transformer Gas Relay, draw
Play gas shield.4, the distortion of voltage waveform, voltage waveform distortion will generate harmonic wave, transformer caused by D.C. magnetic biasing
Harmonic wave can constitute a serious threat to the safe operation of power grid and grid equipment.Be mainly manifested in the following aspects: (1) cause after
Electrical protective device malfunction.(2) capacitor group and static passive compensation device is caused to be overloaded.(3) lead to generator hot-spot
And mechanical oscillation.(4) high voltage DC power transmission converter station end alternating current filter is caused to overload.5, transformer loss increases, direct current
The loss of bias increases the efficiency that can also reduce transformer.When in system more transformers simultaneously by D.C. magnetic biasing when, transformation
Device cluster reactive loss increases, and will cause the total reactive requirement of system and is significantly increased.Since system voltage has lacked reactive power support,
Therefore system voltage is it is possible that catastrophic fluctuation, to threaten the stable operation of system.
The administering method of DC magnetic bias phenomena is generated about transformer in the prior art are as follows: existing scheme thinks that ground connection is neutral
Point be constitute DC current enter the main path of transformer or electric system, thus make transformer generate DC magnetic bias phenomena,
Therefore the administering method used are as follows: the controlling device that installing direct current separates or hinders on transformer neutral point ground line.Chang Cai
Method has following several:
(1) series capacitance is installed in transformer neutral point, to obstruct DC current.
(2) resistance is installed in transformer neutral point, to inhibit DC current.
(3) compensation power supply is installed additional in transformer neutral point, to offset DC current.This method is also known as reverse current injection
Method is a kind of active D.C. magnetic biasing suppressing method.By power supply monitor, calculate and identical to one size of neutral point injection
Reversed direct current offset magnetic bias direct current, and export electric current size and Orientation can be changed.
(4) it connects between transformer neutral point and grounded screen a potential compensation element, in full or part compensation ground
Potential difference between each substation ground network caused by electric current keeps each transformer neutral point current potential in AC network same or similar,
Effectively to inhibit transformer neutral point DC current.
(5) neutral point series connection capacitance-resistance device.Capacitance-resistance device is by resistor, capacitor, by-pass switch and control detection system
The D.C. magnetic biasing controlling device for composition of uniting.
However, present inventor has found afterwards after study, the generation of transformer dc electromagnet phenomenon is because of transformer
There are discharging fault, the fault current generated is flowed by transformer neutral point caused by the DC component of the earth for inside,
It is not that DC current in the earth is entered caused by transformer by grounded neutral.And in existing scheme, by transformation
The controlling device installing direct current partition on device neutral ground line or hindering, may not for administering transformer dc current phenomena
Only without effect, it is also possible to have an adverse effect.
Therefore, the processing method for how providing a kind of transformer DC magnetic bias becomes those skilled in the art's urgent need to resolve
The technical issues of.
Summary of the invention
