摘要
直流耐压试验主要是为了检测绝缘体耐压性能的一种方法,通过试验可以对纸绝缘电缆的性能强弱进行判断,以保证电缆在电力系统中能持续发挥作用。目前,直流耐压试验已经广泛运用于各种电缆的检测,可以及时发现电缆潜在的缺陷,提醒技术人员尽快更换电缆以维护系统运行。由于直流耐压试验过程中遇到各种阻碍因素,导致了试验对电缆寿命造成不利的影响,文章针对这一问题展开深入分析。
DC withstand voltage test is a method mainly in order to detect insulators voltage withstand properties, through the test of pa per insulated cable performance strength judgment, to ensure that the cable in power system can continue to play a role in.At present, the DC withstand voltage test have been widely used in the various cable detection, Can the timely discovery cable potential defects, remind technical personnel as soon as possible to replace cable maintain the system running.Because the DC voltage endurance test of various obstacles encountered in the process,leads to a test on cable life to cause adverse effects,the article for this issue in-depth analysis.
