可调式升流补偿装置研发

Research and Development of Adjustable Up-Current Compensation Device

针对电流互感器校验时一次回路长、回路感抗大、无功功率消耗多、升流困难的问题,研制了可调式升流补偿装置。该装置基于89C51单片机控制、数字功率因数表反馈,通过十进制可调电容调节平衡一次回路感抗,达到减小回路无功消耗的目的,实现电流互感器的全量程校验。可调式升流补偿装置和无功补偿方法可在省市电流互感器检定试验中推广应用。

Aiming at the problems of long primary loop,large loop inductance,high reactive power consumption and difficulty in up-current during current transformer calibration,an adjustable up-current compensation device was developed.The device is based on 89C51 single-chip control,digital power factor meter feedback,and adjusts and balances the primary loop inductance through a decimal adjustable capacitor,so as to reduce the reactive power consumption of the loop and achieve the purpose of full-scale calibration of the current transformer.The adjustable up-current compensation device and the reactive power compensation method can be popularized and applied in the verification test of the provincial and municipal current transformers.
