摘要
本文介绍了AT供电牵引网新型微机故障测距系统,对其抗干扰设计进行了较深入分析,并从系统可靠性、适用性、经济性和精确性等方面,与国内外广泛采用的“AT中性点吸上电流比”原理构成的测距系统进行了全面比较,经试运行表明新型测距系统在各个方面具有明显优势。
The new microprocessor-based fault locating system in AT feeding system for electric traction studied by the authors is introduced briefly ana its anti-disturbance property is analysed thoroughly. In order to help the user select fault locator suitably , this system is compared with that one based on the principle of the AT neutral current ratios. It is indicated that the new fault locator has an advantage in respect of reliability , adaptability,accuracy and economy through theoretical analysis and practical service in the field.
