New IGBT Generation Rectifiers
Passing oil rectifiers
Common rectifiers used in Iran are oily. These power supplies work according to the law of induction. This means that as current flows through their primary winding, the same current is transmitted to the output with a conversion ratio. This current is ac or alternating current and must be rectified at the dc output. For this purpose, a set of diodes is placed in the output. Another problem with these rectifiers is that they do not have the ability to work permanently in the rated current and must be turned off after a few hours to cool their oil. Also, the cost of oil, the possibility of fire and even the size and volume occupied in them is high.
But all the problems raised in oil rectifiers in the new generation rectifiers of Tavan Pajooh Behrad Company have been solved.
The fact is that success is found only in the team and nowhere else!
Precise control of variables
Precise control of rectifier output current and voltage
Accurate regulation of output voltage and current
Ability to stabilize settings
Ability to record rectifier settings for future use
Ability to adjust the rectifier output according to the specified program
Ability to modular design for easy maintenance and repair
Increase output efficiency in exchange for energy consumption
Dimensions less than a quarter of old rectifiers
Proper performance in acidic and polluted environments
Due to the use of new IGBT technology, the energy consumption efficiency of new rectifiers is about 20% higher than traditional rectifiers. For example, by replacing an old 3000 amp rectifier with a new 2000 amp rectifier, the cost of saving energy consumption per year is equal to 5 million Tomans.
Due to the increase in accuracy and reduction of output fluctuations of switching rectifiers (ripples), the ion throwing operation in the new rectifier is much more uniform, which therefore reduces the amount of consumables in the coating process. For example, experience has shown that replacing old rectifiers with switching rectifiers in a nickel bath reduces the nickel anode consumption by about 10 to 15 percent for the same coverage.
Due to the high accuracy and ion throwing power of switching rectifiers in the current injected into the plating bath, the plating time in various plating processes such as hard chromium, nickel, galvanized and acid copper plating is reduced.
As a result of using the new generation IGTB rectifier and removing the old oil rectifiers, savings in resource consumption are created, which ultimately leads to cost reduction.
