Low
Loss 1.Considering
the rectifier transformer always in the actual situation in high
load operation, rectifier transformer is different from power
transformer. In the design of the intention to increase core size,
appropriately inceased the no-load loss, can be greatly reduce the
load loss, generally speaking, the increase of 1 kilowatts of
no-load loss can reduce *0 kilowatts of load loss, thereby reducing
the total loss of rectificer transformer, improved the
efficiency. 2.Selection
of high quality copper: manufacture coil using “extrusion anaerobic
flat copper wire” introduced from British company, compared with
ordinary copper wire, it has a smooth surface without burrs, high
compactness, low resistivity characteristics, so the load loss of
this extrusion anaerobic flat copper wire was lower than
tranditional copper wire. 3.Selection
of high quality silicon steel sheet: iron core manufactured by high
quality cold-rolled oriented grain silicon steel sheet, can reduce
no-load loss appropriatly. 4.Appropriate
increase the cross section of winding turns, to reduce the coil
current density, can reduce some of the load loss, appropriate to
reduce the magnetic flux density, and also allows no-load loss
decreases, so that the total loss
decreases. 5.The
low voltage high current lead wire in transformer using the same
inverse parallel arrangement to balance the lead wire electrical
resistance and improve the power factor, at the same time using our
company’s unique magnetic isolation measures (i.e, using a large
area of the entire magnetic stainless steel plate to cut magnetic),
can effectively reduce the leakagemagnetic field generated by the
stray loss and eddy current loss. Low
Temperature 1.Coil
temperature rise 1)Selecting
a lower current density, reduce the load loss, and fundamentally
reduce the transformer winding temperature rise and top oil
temperature rise. 2)Make
full use of computer simulation technology in coil design,
according to the different requirements of the cooler arrangement
and piping latout, draw the cooling circuit diagram and calculate
the flow resistance and pressure loss of the entire cooling
circuit, and according to the load characteristic curve of the
cooler to calculated the oil flow rate, than place the oil flow
oriented partition in a coil, by adjusting these parameters let oil
flow to the temperature rise area, control each coil temperature in
a given range. 2.Control
part’s overheating 1)According
to the accurate calculation of stray loss in large-capacity
transformers, may arise local hot spots on the structure, different
transformers, different positions can use electromagnetic shielding
or cut off magnetic way to eliminate the structure of local
overheating. 2)Through
the coil end leakage flux calculation, the coil end lines can
determine the horizontal magnetic flux leakage loss, by this
calculation use an appropriate way to avoid coil end lines
temperature rise. No
Leakage 1.Rectifier
transformer low-voltage and high current outlet terminals are easy
to leakage, in this regards, after years of research our company
developed a patented product “ new
impermeableditch-type outlet
terminals”, the component is
completely solve the oil leakage problem of low voltage high
current terminal. 2.Selection
of wide steel plate, no splicing, cutting steel plate edge part cut
off to avoid slag lead to leakage. 3.Seals
use anticorrosive oil resistant high elastic
products. 4.Welding:
double-layer welding of inside and outside, use particle detection
and other means to rigorous test welding seam to ensure no
leakage. 5.Components:
Developing special component test equipment during process,
simulation of field operating conditions with hot oil component of
the vacuum betterfly valve, radiator pressure test as a check and
filter components. 6.Flange:
Ensure the flatness and smoothness of the connecting flange, use a
unique anti-leakage measures in the flange
surface. 7.Structure
design: Complete the seal part of the final product assembly by an
operator to ensure that the flange force uniform without
distortion, to extend the flexibility of the rubber parts
life. 8.Select
large cutting, stamping, shearing, bending equipment to produce, to
let the transformer tank in shape at once as far as possible,
reduce the solder joint, avoid the pores and trachoma on steel
plate, to ensure the fuel tank body no
leakage. 9.Site
Job: Complete transformer site components assemble by a
professional installation team sent by our company, to prevent
improper assembly the oil leakage while expired aging
periods. *0. Return
visit after put into operation. Respectively pay a return visit
irregularly scheduled, tracking service, the service team fastening
flange, thus ensuring that products put into operation until the
entire service period and avoid
leakage. Good
Ability of Anti Short Circuit 1.Our
company has developed a patented technology – “Multi-storey
brushing stacked side circle”, use this technology has greatly
enhanced the coil short circuit
ability. 2.Give
full consideration in the design of products to withstand short
circuit, and adapted six sides of the body of the rigid posiooning
a series measures, to ensure the stability of the entire
product.
