| 摘 要： | 局部放电(简称局放)试验是验证交联聚乙烯绝缘电力电缆(简称交联电缆)及电缆附件质量的重要环节。脉冲电流法一直是目前实验室内进行局放检测的主要方法,该方法在技术上已经较为成熟,且由于实验室内屏蔽效果好,背景干扰低,因此对电缆或电缆附件进行出厂试验之一局放检测效果较好,但是对于运行的电缆或电缆附件进行局放检测,或对已经发现存在局放的电缆回路中进行局放定位,往往需要复杂的波形分析或数学计算。通过利用超声局放测量仪器,对运行前和运行中10 kV交联电缆和电缆分支箱等电缆附件分别进行了局放测量,方法简单易行,取得了较好的效果。

| Abstract: | Partial discharge(referred to as PD) testing is an important process to verify the quality of the cross-linked polyethylene insulated power cable(referred to as XLPE power cable) and its accessories.While the pulse current method has been the main means for PD testing in the laboratory.As a technically matured method,it can effectively carry out the ex-works PD testing of the cable and its accessories due to good shielding effectiveness and low back-ground interference in the laboratory.However,complicated ... |
