A New Online Measurement Method of Rectifier Component Current Balance

The rectifier current balance coefficient is an important index to measure the rectifier output capacity and the evenness of current division.Based on our researches through years and the analysis of all collected data,the concept of temperature balance coefficient is introduced.By measuring the temperature of the rectifier components,the output capacity of the bridge leg modules and the rectifier cabinet can be easily derived from the formula of the temperature balance coefficient computation.This is an efficient way to determine the current balance and output capacity of the rectifier cabinet components.Comparing to the traditional way of measuring the potential drops at both sides of the rapid fuse,the operation of this method is much safer and more reliable.Comparing to an online rectifier tester,it has advantages of low cost and high stability.
