【摘要】 提出了应用质量流量的充油电力电缆漏油点定位技术。理论分析和实际应用结果证实该技术减少了因温度变化引起电缆油“热流”所导致的测量误差 ,对漏油量 >30 L/ d的漏油点有较好的定位准确度 ;对漏油量 >7L / d的漏油点亦有较好的参考价值。更多还原

【Abstract】 The technique that apply mass-flowmeter to locate the oil leaking of power cable is put forward in this paper. It has been proved by theory analysis and practical application. The locating precision for oil leakage≥30 liters a day is much better and for the oil leakage≥7 liters a day it can be located approximately because this technique reduces the calculating error of ‘hot-flow’of cable oil caused by temperature change.更多还原
