摘要
针对高压电缆缺陷状态开展模拟试验研究,设计搭建了高压电缆状态仿真平台。该仿真平台由升压单元、电缆模型单元、升流单元和控制测量单元组成,集成了局部放电、温度、接地电流等在线监测装置,可模拟制作各类主绝缘、半导电、接地系统及绝缘件缺陷。针对仿真平台各组成部分功能,通过精度校验和试验校核,分析验证其试验、检测能力,确保试验结果的准确性和精确性。分析结果表明,该仿真平台具备模拟高压电缆各类绝缘缺陷并进行检测分析、状态评估的能力。
According to the simulation experiment of the high voltage cable defect state, this paper designed and constructed a high volt-age cable state simulation platform. The simulation platform included booster unit, cable model unit, up-fow unit and control-measure unit and integrated partial discharge, temperature and ground current etc online monitoring devices, being able to simulate various types of main insulation, semi-conductive layer, grounding system and insulation defects with measurement. In view of the function of each component of the simulation platform, the accuracy of the test results are verifed and analyzed through the verifcation of the accuracy and test. The analy-sis results show that the simulation platform has the ability to simulate all kinds of insulation defects of high voltage cables, and to detect, analyze and evaluate the status.
