Abstract
An amorphous alloy on-load voltage regulation transformer, 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 voltage regulation transformer comprises a transformer housing, a iron core mounted in the transformer housing, and a high-voltage winding and a lower-voltage winding which are sleeved on the iron core, a on-load tapping changing switch is arranged on the transformer housing, the high-voltage winding has corresponding 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.
Description
Technical field
The utility model relates to the device that electric energy transmitting is carried out in a kind of electric power system, relates in particular to a kind of energy-saving and cost-reducing amorphous alloy transformer of electric power system distribution system that is used for.
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.For the voltage that guarantees user side reach rated voltage near, in the electric power course of conveying, in order to remedy voltage loss along supply line, the head end voltage of supply line will be higher than the rated voltage of circuit, near the power consumption equipment that is linked in the circuit head end usually is in be higher than the rated voltage state under and works, not only caused the waste of electric power, the useful life of also obvious shortening 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, but the problem of bringing simultaneously is after peak times of power consumption, occurs the too high phenomenon of supply power voltage again, causes the minimizing in waste of electric energy and consuming device life-span.The efficient of various consuming devices, useful life is near dimension the best its rated voltage all.Therefore, often keeping the qualified of transformer output voltage, each electric equipment is often operated near the rated voltage, is economical rationality the most.The present price section, transformer can not be adjusted load side 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 under the on-load state, adjust the load side change in voltage according to ruuning situation, thereby cause the step down side voltage fluctuation bigger, influenced the problem of power supply quality.A kind of non-crystaline amorphous metal on-load tap-changing transformer is provided.
The utility model comprises the transformer housing, is installed in the interior iron core of transformer housing, is nested with high pressure winding and low pressure winding on iron core, the transformer housing is provided with on load tap changer, the high pressure winding has corresponding tap, and described 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.
