用于电流型电子式电压互感器的积分电路
An Integral Circuit for Current-Based Electronic Voltage Transformer
摘要
Abstract
Integral circuit is the key element to restore the signal in the current-based electronic voltage transformer(EVT) , and its performance directly affects the steady and the transient characteristics of the EVT .An integral circuit with DC-isolating con-trol used in the current-based EVT was proposed .It can effectively block the DC component of the input signal ,resulting in the im-provement of the transient performance of the EVT .And its frequency width can assure below 40th harmonic voltage measurement . The method of using the thermal resistor to compensate the temperature characteristic of the integral circuit was also proposed ,which can improve the stability of the EVT .An EVT prototype based on the designed integral circuit was developed and then tested .The analysis and then experimental results demonstrated the practicability and the validity of the proposed integral circuit .关键词
