The loaded voltage-regulating amorphous alloy power transformer solves the problem of the power supply quality and loss of a transformer. The utility model comprises a transformer casing, a high-voltage winding and a low-voltage winding, wherein the low-voltage winding and the high-voltage winding are arranged in the casing; the high-voltage winding and the low-voltage winding are sheathed on the iron core. The utility model is characterized in that the casing is provided with a loaded voltage regulating switch and the operating controller thereof; the high-voltage winding is composed of at least two sets of coils which are connected in series together; each set of the coils is provided with coil taps respectively; the coil taps as the loaded voltage regulating switch are connected with connected ends; an iron core which is sheathed with the high-voltage winding and the low-voltage winding is an amorphous alloy iron core. The position switching of a tap joint of the loaded voltage regulating switch is realized by operating the loaded voltage regulating switch, so a high-voltage winding tap of a transformer realize synchronizing sequential transformation, voltage ratio of the transformer is changed for altering output voltage and keep the transformer stable. By making use of the amorphous alloy iron core transformer, no-load loss is decreased greatly, and electric energy loss of an electric network is reduced. The utility model is suitable for being used in urban networks or rural networks largely.
Description
Affiliated field
The utility model relates to a kind of power transformer, is specially a kind of on-load voltage regulation non-crystalline alloy power transformer.
Background technology
In the electric power course of conveying, loss for fear of supply line, to be sent to end with higher voltage, it is user side, terminal power consumption equipment usually is in is higher than work under the rated voltage state, 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, and 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, occur the overvoltage power supply again, cause waste.The loss of power consumption equipment mainly contains copper loss and iron loss two parts, and the total losses value is near rated voltage for minimum running status.Therefore, often keeping the qualified of transformer output voltage, make each electric equipment often operate in the rated voltage situation, is economical rationality the most.The present price section, 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.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of on-load voltage regulation non-crystalline alloy power transformer, can carry out voltage-regulation under the transformer live state according to payload.
The technical solution of the utility model is: the on-load voltage regulation non-crystalline alloy power transformer, comprise the transformer housing, be installed in the iron core in the housing and be nested with high pressure winding, low pressure winding on iron core, it is characterized in that: housing is provided with on-load voltage regulating switch and operating control device thereof, the high pressure winding is made of at least two group coil tandems, each is organized coil and has separately coil tap, and coil tap connects the termination of inserting as on-load voltage regulating switch; The iron core that described winding was nested with is an amorphous alloy iron core.
By operation on-load voltage regulating switch operating control device, on-load voltage regulating switch is rotated, realize the switching of on-load voltage regulating switch tap joint position, make the transformer high-voltage tapping realize the synchronizing sequence conversion, thereby the voltage ratio that makes transformer changes and changes output voltage, makes it keep stable.
The beneficial effects of the utility model are: it has realized that operating transformer voltage adjusts automatically according to load variations, substitute conventional artificial power failure adjustment, guarantee the continuity of power supply, the stability of output voltage, thereby significantly improve power supply quality, for economical operation, prolongation service life of equipment and power network schedule automation create conditions; Adopt the amorphous alloy core transformer, no-load loss reduces significantly, significantly reduce the electric energy loss of electrical network, the operation noise is low, be lower than the quiet sub-district of urban life and require index, floor space is little, and it is very convenient to install and use, extremely be fit to large tracts of land use in city net and the rural power grids, it mainly is applicable to the quality of voltage requirement than higher scientific research building, hotel and enterprises and institutions and vast city net, rural power grids and transformer station.
