SH15-M Series

Amorphous Alloy Oil-immersed Transformer

Introduction of Products

Amorphous alloy isderived from iron, boron and other elements which rapid cooling down to mouldin order to arrange its atoms disordered. Compared with silicon sheets, the permeabilityof amorphous alloy is high, the no-load losses and current is lower, and moreoperation charges can be saved. Meanwhile, its heat is lowand it has good stability to make its working lifelonger.

Performance Characteristics

1.     Saving power: The no-load losses reduce byabout 80% than that of S9 series.

2.     Reliable: The capability of anti-shortcircuit is strong.

3.     Protecting environment: Its noise is lowand it can decrease the discharging quantity of carbon.

Structure Characteristics

1. The core adopts three-phase five-limb and HV winding adopts D connection,which eliminates the three fluxes and three-harmonic electric potential anddecrease eddy current loss and temperature caused by leakage. Meanwhile, the steepnessof impulse voltage is reduced.

2. The coil takesthe shape of rectangular, and use conductor tensioning device to wind. Itadopts shaping, press mounting and other technique measures to make the outsidedimension of coil come to design requirement. And that HV coils wind outside LVcoils improve the strength of coil and the capability of anti-short circuit.

3. There is no oilstorage tank and moisture absorber on the oil tank. The transformer oil doesn’tcontact with the air and the expansion of oil depends on the elasticity of corrugatedplates to compensate. This can eliminate maintenance and improve working life.

Q:AC Transformer & Circuit Board Problem?
Either its wired incorectly or there's a brief within the cooling circuit. I advise placing a 3A fuse in front of the transformer. Comfortably splice it within the 24 v leg between the circuit board and transformer with two feminine connectors and the fuse appears just like the fuses that go into your car underneath the steerage column. The brief might be in quite a couple of extraordinary places probably the most located place for a brief in the cooling circuit is rotted out insulation on the thermostat wiring going into the condensing unit.
Q:electronics -pls explain about transformers,ICC,etc?
google search MAKE magazine
Q:Test of Polarity and location of windings of a 3 pahse transformer?
It sounds like you have a three phase transformer. In the cover plate there normally is a drawing to guide you on what you want to do. Most trans formers can have input voltages of 440 volts in to 240 ouput. but some can provide 115 volts on the output if wired correctly. Any transfomer compnay website provide wiring drawings that pretty match everyones transformers. Contact the manufacturer of the transformer for instructions.
Q:what are the properties of electrical transformers ? their uses ? their applications ?
1 - Transformers step-up or step-down voltage in a closed electrical circuit. 2 - Power companies send electricity at over 500,000 volts through power lines. They use transformers to convert their power to this level and a second set which lower the voltage for home/office use. 3 - Allowing you to use electricity at different voltage levels for different applications.
Q:transformer - install in electrical box only?
your line voltage leads should be inside and connections to low volt outside,but neither side needs to be exposed to the weather or an open area,if someone touches the leads evern though its 24 volts it still hurts,and it doesnt need to get wet
Q:short-circuit and open circuit transformer question?
read material regarding transformers Not just once but say 5 times, till you understand what is said. the transformer has copper loss due resistance of primary and secondary. It has additionally iron loss. The equivalent circuit is a sort of representation that brings in these losses. generally you can apply a low voltage to primary till shorted secondary has a current equal to less than rated current. These measurement details are given. Similarly open circuit measurement details are available. With understanding of how the rest can be calculated using worked examples in texts, you can solve it yourself. attempt this See Lee's book on transformers or schaums series on electrical engg.
Q:Why 21 lighting transformers must use double-winding safety isolating transformers,
The double-winding type safety isolating transformer has two windings which are input (primary) windings and output (secondary) windings, and the two windings are insulated from each other, only by magnetic connection, that is, secondary Winding and the earth does not constitute a loop, if the use of additional insulation appliances, you should use a safe isolation transformer. And since the lotus transformer all of its winding are connected, by sliding the position of the contact to change the size of the voltage. Therefore, the autotransformer primary winding (power circuit) and the secondary winding (power supply circuit) is not only between the magnetic connection, as well as the direct connection of the circuit. It and the earth constitute a loop, so it can not be used as a safe voltage power supply. Therefore, the safety regulations: lighting transformers must use double-winding type safety isolation transformer, prohibit the use of autotransformers.
Q:How do you convert from Volts to Amperes if the Current Transformer is 2500:1?
NO such thing as a DC transformer. Do you mean an AC voltage transformer with rectifiers on the output? But ohms law should apply. Current voltage divided by resistance.
Q:Can i used scott t transformer with welding machine ?
you're starting to be to be meant a single section welding device. This unit includes 2 supply lines. those lines may be linked to any 2 lines of a three-phse ability supply device.only connect one line to L1 and the different line to L2, only examine the line to line voltage of the flexibility supply. It must be the comparable by way of fact the welding device score, say, 380VOLTS, 50 Hz.
Q:What is the principle of the conversion of the transformer? How to restore the secondary side to the primary side?
Understand P1 = P2 (no loss here). To know the return of the.
