Main Advantages of Rectifier transformer

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.
