Description
Technical field
The utility model relates to anti-humorous wave transformer in a kind of electric power system, belongs to transformer technology field.
Background technology
Transformer is one of of paramount importance electric equipment of electric utility, also be important energy consuming equipment, adopt new material, new technology and new technology, reduce the electric energy loss of transformer, transmission high-quality clean energy resource, reduce the generation of pernicious gas, be the target of electric equipment manufacturer unremitting pursue always, is also the source and the power that promote transformer industry progress and development.
In electric power system, the basic reason that harmonic wave produces is caused by nonlinear load.Predominant non-linearity load has UPS, Switching Power Supply, rectifier, frequency converter, inverter etc.Nearly 30 or 40 years, developing rapidly of various power electronic equipment makes the harmonic pollution of utility network be on the rise, harmonic wave makes the production of electric energy, the efficiency of transmission and utilization reduces, make device of overheating of electrical, produce vibration & noise, and make ageing of insulation, useful life shortens, and even breaks down or burns.Harmonic wave can cause electric power system local parallel resonant or series resonance, harmonic content is amplified, causes the equipment burnouts such as capacitor.Harmonic wave also can cause relaying protection and automatics misoperation, and electric energy metrical is caused confusion.Outside for electric power system, harmonic wave can produce severe jamming to communication equipment and electronic equipment.The harm of harmonic wave has caused the concern of people's height.
Utility model content
Utility model object: for problems of the prior art with not enough, the utility model provides the one be applied in electric power system to resist humorous wave transformer, solves the problem of harmonic wave in electric power system.
Technical scheme: anti-humorous wave transformer in a kind of electric power system, comprise amorphous alloy core, first side winding and secondary side winding, described amorphous alloy core is the iron core of three-phase three-limb or three-phase five-limb structure, employing non-crystaline amorphous metal is made, significantly reduce transformer noload losses, no-load loss comparatively traditional silicon steel disc transformer declines more than 70%, is conducive to reducing circuit operating cost.Effective reduction, on the impact of Transformer Winding Temperature Rise, has delayed the aging speed of dielectric, reduces the generation of the pernicious gas such as CO, SO, NO in transformer, can reduce the environmental pollution to air.
Described first side winding adopts delta connection structure, disc coil, and turn-to-turn employing Du Pont NOMEX paper does and insulate, and adopt technique of vacuum pressure for dipping electrical (VPI), further eliminate coil inside corona phenomenon, mechanical strength is high, and heat radiation is very easy to.
Described secondary side winding adopts meander configuration wiring construction (ZigZag), paper tinsel is around formula coil, and interlayer employing Du Pont NOMEX paper does and insulate, and makes to produce without uneven ampere-turn between coil, winding can bear short circuit, overload and overvoltage and local overheating not occur, and thermal endurance class is high.Secondary and a homophase, be with neutral zero line, effectively can reduce by 3 subharmonic that 3 times, 5 times, 7 times main harmonic content and single-phase load produce, and effectively transfer neutral point current thermal effect, lowers the impact on data communications equipment.
Beneficial effect: anti-humorous wave transformer in electric power system provided by the utility model, tool has the following advantages:
1, can reduce the electric energy loss of transformer significantly, no-load loss comparatively traditional silicon steel disc transformer declines more than 70%, is conducive to reducing circuit operating cost.Effective reduction, on the impact of Transformer Winding Temperature Rise, has delayed the aging speed of dielectric, reduces the generation of the pernicious gas such as CO, SO, NO in transformer, can reduce the environmental pollution to air.
2, for electric power system, transformer adopts meander configuration (ZigZag) wiring construction, can effectively reduce by 3 times, 5 times, 3 subharmonic that 7 main harmonic content and single-phase load produce, and effectively transfer neutral point current thermal effect, lowers the impact on data communications equipment.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model example structure;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the elementary diagram of the utility model embodiment;
Wherein, 1, first side winding, 2, secondary side winding, 3, unshakable in one's determination.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As Figure 1-3, in a kind of electric power system, anti-humorous wave transformer, comprises first side winding 1, secondary side winding 2, amorphous alloy core 3;
3 structures unshakable in one's determination are three-phase five-limb or three-phase three-limb, adopt amorphous alloy material to make, the more conventional dry change decline about 70% of no-load loss.Effectively can reduce the impact on Transformer Winding Temperature Rise, delay the aging speed of dielectric, reduce the generation of the pernicious gas such as CO, SO, NO in transformer, the environmental pollution to air can be reduced.
First side winding 1 adopts delta connection structure, disc coil, and turn-to-turn employing Du Pont NOMEX paper does and insulate, and main insulation can adopt the solid+Electrode in Gas Insulated System increasing creep distance, effectively shortens insulation distance.Adopt technique of vacuum pressure for dipping electrical (VPI), further eliminate coil inside corona phenomenon, can effectively reduction office put.Mechanical strength is high, and heat radiation is very easy to.
Secondary side winding 2 adopts meander configuration wiring construction (ZigZag), and paper tinsel is around formula coil, and interlayer employing Du Pont NOMEX paper does and insulate, and make to produce without uneven ampere-turn between coil, winding can bear short circuit, overload and overvoltage and local overheating does not occur, and thermal endurance class is high.Secondary side winding 2 and first side winding 1 homophase, be with neutral zero line, effectively can reduce by 3 subharmonic that 3 times, 5 times, 7 times main harmonic content produce with single-phase load, effectively shifts neutral point current thermal effect, lower the impact on data communications equipment.
