摘要
做好交联聚乙烯绝缘电缆的交接和预防性(重做终端和接头)试验是保证安全运行的重要工作。为此,阐述了交联聚乙烯绝缘电缆的交接和预防性试验有关问题,提出6～10kV和35kV交联聚乙烯绝缘电缆不同的试验方法和内容。并指出传统的直流耐压试验存在不足之处,对交联聚乙烯绝缘电缆的交接和预防性试验应优先采用变频率串联谐振试验。
The acceptance test and the preventive test (on remade terminals and joints) of XLPE cables are important to safe operation. This paper expatiates on the different methods and contents of acceptance and preventive tests of 6～10 kV and 35 kV XLPE cables, indicating the defects in conventional DC voltage withstand test and recommending variable^frequency series^resonant test for the acceptance and preventive tests of XLPE cables.
