| 摘 要： | 冲击性负载易在配电网中产生大的电压波动及较高的电流谐波,在这种复杂的供电环境中,应用简单的MOC3083光电触发系统容易产生误触发.TSC无功补偿装置能够很好地补偿轧钢厂中轧机类冲击性负荷所产生的无功功率及谐波.根据TSC触发电路的要求,设计了一套新的光电隔离系统,用来检测晶闸管电压的过零点,并采用电磁触发方式触发晶闸管.实验证明该触发系统能够在复杂的电网下稳定、可靠地工作.

| Abstract: | Because of the voltage fluctuations and current harmonic of the distribution network are very high,the simple application of the photoelectric MOC3083 trigger system can lead to mis-trigger in the complex power supply environment.TSC reactive compensator is very suitable for compensating the reactive power and filtering harmonics caused by surge road of the rolling mills.According to the requirements of TSC trigger circuit,a new photoelectric isolation system is designed to detect the zero-cross of the thyr... |
