贵阳地区10kV电缆运维能力分析和改进探讨

Analysis and improvement discussion of 10 kV cable operational capacity in Guiyang

贵阳地区目前在电缆测试手段上与先进地区差距较大,交接试验,预防性试验,测试手段仅有直流和交流耐压两种,无法发现缺陷,故障定位只有简单的便携式故障定位仪,功能简单,可靠性差。建议全面开展震荡波局放测试,作为交接性试验必须开展的项目,配置震荡波局放测试设备。

We have a gap when compared with the advanced region at present. The test means are only DC and AC withstand voltage methods in handover test and preventive test which can＇ t find defect. We only have a simple portable fault locator with simple function and poor reliability to get fault location. This paper suggest carrying out comprehensive shock wave partial discharge test as the necessary project of handover test, and disposing shock wave partial discharge test equipment.
