Abstract
An amorphous alloy on-load variac, relates to a device for the electric energy transmission by a power system, solving the problem that the present transformer takes silicon-steel sheet as the iron core, thus the zero load loss is big and the energy-saving effect is poor, and the load side voltage change can not be adjusted under the condition that the load is carried in the running state, thus the load side voltage of the transformer has big fluctuation, the power supply quality is effected. The amorphous alloy on-load variac comprises a transformer housing, a iron core mounted in the transformer housing, and a three-phase winding sleeved on the iron core, a on-load tapping changing switch is arranged on the transformer housing, each winding of the three-phase winding has coiling tap which is taken as the end connected with the on-load tapping changing switch, the iron core is an amorphous alloy iron core. The amorphous alloy iron core is adopted to reduce the zero load loss of the transformer by 60%, thus the energy-saving effect is good. The transformer has the on-load voltage function, so that the three-phase winding quality of the user is improved.
Description
Technical field

Background technology
In the generating-transmission of electricity-distribution-usefulness electric process of electric power system, for can being transported to by the generating center economical, safely and reliably, electric energy uses electrfic centre, one kilowatt generator often needs to dispose 8 kilovolt-amperes～10 kilovolt-amperes transformer, simultaneously owing to the no-load loss of transformer is fixed, as long as just there is no-load loss in transformer former limit energising, and does not change with the change of loading.The no-load loss of general power transformer accounts for about 0.1%～0.2% of its rated capacity, therefore the electric energy that sends of generating equipment just has 1%～2% electric energy to be consumed by the no-load loss of transformer in transmission course, therefore the no-load loss of being badly in need of reducing transformer itself reaches energy saving purposes to reduce the line loss of electric power system; Simultaneously because the load of electric power system is to change at any time, the voltage of electrical network also is that the variation with system loading changes, in the electric power course of conveying, in order to remedy the voltage loss of supply line, the voltage of supply line's head end will be higher than the rated voltage of circuit, make that be connected near the head end power consumption equipment often is in to be higher than under the rated voltage and works, not only caused the waste of electric power, also can seriously shorten the useful life of equipment.On the other hand, in order to guarantee during peak of power consumption, under the situation that user side voltage descends to some extent, equipment still can normally move, usually with the rated voltage that is higher than of the output voltage of supply transformer design, the problem of meanwhile bringing is after peak times of power consumption, occurs the overvoltage power supply again, causes waste.Tieing up in the efficient of power consumption equipment and useful life bestly near its rated voltage, therefore, often keep the qualified of transformer output voltage, make each electric equipment often operate in the rated voltage situation, is economical rationality the most.Present stage, transformer can not be adjusted the load side change in voltage according to ruuning situation under electriferous state, easily cause the step down side voltage fluctuation bigger, has influenced power supply quality; And existing transformer mostly adopts silicon steel sheet to make iron core, and no-load loss is big, and energy-saving effect is undesirable.
The utility model content
The purpose of this utility model is to make iron core in order to solve existing transformer adopting silicon steel sheet, no-load loss is big, the unfavorable problem of energy-saving effect, and can not be according to ruuning situation, under electriferous state, adjust the load side change in voltage, easily cause the step down side voltage fluctuation bigger, influenced the problem of power supply quality.Provide a kind of non-crystaline amorphous metal that the variac of carrying is arranged.
The utility model comprises the transformer housing, be installed in the iron core in the transformer housing and be nested with three phase windings on iron core, the transformer housing is provided with on load tap changer, every phase winding in three phase windings has coil tap separately, and described coil tap connects the termination of inserting as on load tap changer; Described iron core is an amorphous alloy iron core.
Advantage of the present utility model: iron core adopts the amorphous alloy material with high magnetic conduction, ultra-low loss, make the no-load loss of transformer reduce about 60% than the common S11 type transformer that adopts silicon sheet core, energy-saving effect is very obvious, energy-saving and cost-reducing significant to electrical network.Owing to have load tapchanging function, the economy and the reliability of operation of power networks can be effectively improved simultaneously, the electricity quality of using of power consumer can be improved effectively.Autotransformer with capacity is compared with common transformer, and not only size is little, and the efficient height, and transformer capacity is big more, and voltage is high more. and this advantage is just all the more outstanding.
