Electric protection is used (PT, CT);The transformer of specific use has smelting furnace transformer, welding transformer, electrolytic rectifier to become
Depressor, small-sized adjustable transformer etc..
Power transformer is a kind of static electrical equipment, is for the alternating voltage (electric current) of a certain numerical value is become frequency
The equipment of the different voltage (electric current) of the identical another or several numerical value of rate.When first winding passes to alternating current, just produce
The magnetic flux of alternation, the magnetic flux of alternation are acted on by iron core magnetic conduction, and AC electromotive force is just induced in secondary winding.Secondary sensing
The height of electromotive force is related with the number of a secondary winding number of turn, i.e., voltage swing is directly proportional to the number of turn.Main function is transmission
Electric energy, therefore, rated capacity are its major parameters.Rated capacity is the usual value of a performance power, it is characterization transmission
The size of electric energy, is represented with kVA or MVA, when applying rated voltage to transformer, is determined under prescribed conditions not according to it
More than the rated current of temperature limit.More energy saving power transformer is Amorphous Alloy Distribution Transformer, its maximum is excellent
Point is that no-load loss value spy is low.It can finally ensure no-load loss value, be that the core to be considered in whole design process is asked
Topic.When being arranged in product structure, except amorphous alloy core to be considered in itself from the effect of external force in addition to, while calculate when also
The characterisitic parameter of the accurate Rational choice non-crystaline amorphous metal of palpus.
Existing power transformer is generally equipped with oil conservater, with the increase and decrease of the transformer oil in oil conservater, transformer
Inside inevitably touches air, so as to result in the deterioration and humidified insulation and aging of oil, causes operation to run into barrier
Hinder, poor reliability.
Utility model content:
The technical problem to be solved by the utility model is to overcome existing technological deficiency, there is provided a kind of power transformer
Device.
Technical problem to be solved in the utility model is realized using following technical solution:
A kind of power transformer, including the corrugated tank of transformer body is internally provided with, the corrugated tank top installation
Cored winding construction, the corrugated tank both sides are respectively equipped with wing plate.
Further, the iron core in the iron core winding construction uses cold-reduced silicon sheet.Magnetic flux density is effectively improved to exist
Distribution situation inside iron core, reduces noise and loss, and core profile convolute coil is cylinder mode, and ampere-turn distribution is equal
Even, insulation system is reasonable, has very strong anti-short circuit capability.
Further, the thickness of the silicon steel sheet is 0.27mm.
Further, the transformer body shell surrounding is provided with corrugated plate, and the corrugated plate is away from transformer body
The side of shell is provided with round steel.
The beneficial effects of the utility model are:Product eliminates oil conservater, and the wing plate on corrugated tank is cold as radiating
But element, at the same with transformer oil increase and decrease and breathing, make inside transformer and isolated from atmosphere, prevent oil deterioration and insulation
Make moist and aging, enhance reliability of operation.
