| 中文摘要: |
| 局部放电是造成XLPE电缆绝缘劣化的主要原因。检测局部放电信号能判断电缆绝缘状态,减少电力绝缘击穿事故发生。研制了一套新型便携式电缆局部放电带电检测系统,阐述了工作原理与硬件设计。系统基于高频电流法、特高频法和超声法,对电缆的绝缘状态进行评估,通过结合三种检测方法的数据分析,大幅提高了系统抗干扰能力和检测结果的可靠性。 |
| 英文摘要: |
| Partial discharge is the main cause of insulation deterioration of XLPE cables. By detecting partial discharge signal, we can judge cable insulation status and reduce electric insulation breakdown accidents. This paper develops a novel portable live detection system for partial cable discharge and expounds its working principle and hardware design. The system assesses cable insulation status in the HF current method, UHF method and ultrasonic method. Data analysis of the three detection methods helps to greatly improve system anti-jamming capability and the reliability of the detection result. |
