Description
Technical field
The utility model relates to a kind of low-voltage coil of amorphous dry-type transformer, belongs to novel energy-conserving transformer technology field.
Background technology
The iron core of amorphous alloy transformer uses the manufacture of non-crystaline amorphous metal material, non-crystaline amorphous metal material is generally iron, nickel, cobalt, chromium, these Its Related Elements of manganese are basic as alloy, and add less boron, carbon, silicon, these elements of phosphorus, use rapid quench solidification manufacturing technology, its metallic atom sequencing table reveals mixed and disorderly noncrystalline state, its demagnetization and the process that is magnetized is made to be very easy to realize, the coercive force of non-crystaline amorphous metal is lower than 4A/m, be approximately 1/7 of silicon steel sheet, the scope that its magnetic hysteresis loop comprises is well below cold-reduced silicon sheet, so the magnetic hysteresis loss of non-crystaline amorphous metal is more much lower than cold-reduced silicon sheet.And the thickness of non-crystaline amorphous metal material is only 25-30 μm, be approximately 1/10 of silicon steel sheet, resistance ratios is approximately 3 times of silicon steel sheet, so the eddy current loss of amorphous alloy iron core is more much lower than cold-reduced silicon sheet.The zero load consume of amorphous alloy transformer is very little, and its unloaded consume reduces about 75% than same range S11 model.
The foil coil that the low-voltage coil of amorphous dry-type transformer normally adopts Copper Foil to manufacture, the epoxy resin sealing structure using glass material to strengthen, possess good moisture proof and the function of break-resistance, be particularly useful for the place that the fire preventing standards such as easy burning, easily blast are higher.Low-voltage coil of the prior art needs orthogonal for foil resin-cast coil, thus increase anti-short circuit capability, complete the work of copper bar outlet on time, coil needs to adopt disk spring compressing structure, to the power that low-voltage coil one is constant, ensure that the vibrations of transformer operationally iron core can not be delivered to coil, reduce the noise of transformer.This makes the complex structure of the low-voltage coil of amorphous dry-type transformer of the prior art, and cost of manufacture is high.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of low-voltage coil of novel amorphous dry-type transformer.
The low-voltage coil of amorphous dry-type transformer described in the utility model is double-layer circular cartridge type, left around to, winding protruding head is long is 250mm, lift one's head with strap and tightening belt rope tight, the total number of plies of this low-voltage coil is 2 layers, every layer of number of turn is 11.5 circles, and in every coil, total number of turns is 23 circles, and interlayer adopts the insulation of insulating point gummed paper; Comprise: the first cardboard, the first insulating end ring, the second insulating end ring, 3rd insulating end ring, the 4th insulating end ring, wire, first corrugated board, second cardboard, the second corrugated board, and insulating point gummed paper, wherein the first corrugated board is arranged on inside the second cardboard, second corrugated board is arranged in the middle of insulating point gummed paper, outermost layer with insulating point gummed paper after one deck, with tightening belt half-lap one deck.
The rated capacity of described low-voltage coil is 315KVA, and rated voltage is 400V.
The phase current of described low-voltage coil is 454.7A.
Described wire is paper-covered copper flat wire.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
The vibrational power flow of low-voltage coil is reasonable, and overall structure is firm, and volume is little, lightweight, do not need orthogonal for foil resin-cast coil, do not need to adopt disk spring compressing structure yet, the vibrations of transformer operationally iron core can not be delivered to coil, reduce the noise of transformer.This makes the structure of the low-voltage coil of amorphous dry-type transformer of the present utility model simple, and cost of manufacture reduces greatly.
