电容型设备介损检测仪的设计

DESIGN OF MEASURING SYSTEM OF DIELECTRIC LOSS tan δ FOR CAPACITIVE-TYPE EQUIPMENT

介绍了一种基于基波相位分离法的电气设备绝缘介质损耗数字化检测方法,根据其原理设计了以DS80C320型单片机构成的绝缘介损检测仪,详细描述了其硬件组成和软件设计,给出了该仪器装置测量的试验结果。

The paper describes a digital measurement method - fundamental frequency phase detachment method - which is used for detecting the dielectric loss of electric equipment. A measuring system of dielectric loss tan S controlled by type DS80C320 CPU is presented, including its hardware circuit and software arithmetic. Experimental results have verified the effectiveness of the method.
