The energy-saving filter low-noise transformer can greatly reduce harmonic loss, and vibration and noise caused by high frequency component, and is fine in energy saving effect.
Description
Technical field
The utility model relates to a kind of energy-conservation filtering low noise type transformer, and the utility model can be widely used in industrial cousumers such as chemical industry, metallurgy, electric iron, and high pressure/super high voltage direct current electricity transmission current conversion station.
Technical background
At present, serious, the problems such as power factor is low, operational efficiency is low, operating noise height of AC and DC power electronics converting means ubiquity harmonic pollution, this will certainly cause waste of energy to a certain extent, brings negative effect to economic benefit of enterprises.And harmonic current is harassed to grid side, also can cause certain pollution to electrical network, influences the safety and economic operation of electrical network.Traditional solution mainly adopts passive or the active power filtering dual mode.Passive filtration unit generally is connected to grid side, and filter effect is subjected to the influence of system impedance bigger, and easy and system impedance generation series/parallel resonance causes the amplification of some subharmonic current, and this can bring negative influence to the safety and economic operation of electrical network equally.Moreover, above-mentioned two kinds of methods all are that passive type ground solves harmonic wave and idle harmful effect to electrical network, but do not improve as for harmonic wave and the idle harm that transformer itself is brought.Non-linear harmonic wave that produces and idle free flow in electric equipments such as transformer owing to the Technics of Power Electronic Conversion device, this will certainly cause running wastage to a certain extent, shortened the useful life of main equipment, and made the noise of electric equipments such as transformer increase, efficient reduces.
The utility model content
Problems such as existing transformer energy consumption is big, efficient is low, harmonic wave is big in order to solve, noise height, the utility model proposes a kind of energy-conservation filtering low noise type transformer, this energy-conservation filtering low noise type transformer can reduce the harmonic loss of transformer and greatly by the caused noise and vibration of high fdrequency component.
Technical solution of the present utility model is as follows:
A kind of energy-conservation filtering low noise type transformer adopts multiple secondary winding, comprises high pressure winding, low pressure winding and shielding winding, and the shielding winding is arranged between high pressure winding and the low pressure winding, and shielding winding and filtering compensation device join.
Beneficial effect:
The utility model patent has proposed a kind of energy-conservation filtering low noise type transformer, this transformer can not only elevator system operational efficiency, and can realize the constant control of High Power Factor and good harmonic shielding, reduce the electromagnetic noise of the main electric equipment that is attached thereto, play the effect of energy-conserving and environment-protective.Energy-conservation filtering low noise type transformer adopting multiple secondary winding pattern is divided into high pressure winding, shielding winding, low pressure winding.The shielding winding is arranged between high pressure winding and the low pressure winding, forms a short-circuited conducting sleeve.By connecting tuning at the shielding winding and merit benefit device, realize the effective shielding of harmonic wave and the constant control of High Power Factor are realized the high-efficiency operation of system.
The utility model is when improving using electricity system (as DC power station) operational efficiency, realize the constant control of High Power Factor, and the harmonic shielding that content is bigger is in the secondary side winding of energy-conservation filtering low noise type transformer, greatly reduces the harmonic loss of transformer and by the caused noise and vibration of high fdrequency component.

Fig. 1 is the structural representation of embodiment 1.
Label declaration: 1-AC power, the energy-conservation filtering low noise type of 2-transformer, 3-rectifier, 4-DC load, 5-filtering compensation device.
Embodiment
Below with reference to figure and specific implementation process the utility model is described in further details:
Embodiment 1:
This example is being example with energy-conservation filtering low noise type transformer application of the present utility model in DC power station, be specially, as Fig. 1, DC power station is connected to form successively by AC power 1, energy-conservation filtering low noise type transformer 2, rectifier 3 and DC load 4, energy-conservation filtering low noise type transformer 2 comprises high pressure winding, low pressure winding and shielding winding, the shielding winding is arranged between high pressure winding and the low pressure winding, and shielding winding and filtering compensation device 5 join.
Energy-conservation filtering low noise type transformer 2 adopts the multiple secondary winding pattern, its first side winding connects AC power 1 (for electrical network or generating end), its secondary side low pressure winding is connected with supply load rectifier 3, and the shielding winding adopts delta connection in its secondary side, be arranged between high pressure winding and the low pressure winding the tuning and filtering compensation device 5 of output termination.The output of rectifier 3 is connected with DC load 4.Filtering compensation device 5 can be made up of the filter with different structure type, its effect is to form short-circuited conducting sleeve with the shielding winding, to the in addition tuning drainage of the harmonic current that produces by rectifier 3, make it and High-Voltage Network side Isolated Shield, and the reactive power compensation of filtering compensation device 5 can compensate the reactive requirement of commutation system.
In addition, the secondary side of energy-conservation filtering low noise type transformer can also directly connect AC load, as arc furnace etc.
