| 摘 要： | 针对胜利油田采油场用电设备采用配电型避雷器进行保护收效不理想的情况,对油田6kV及1140V线路的雷电过电压情况进行了分析及研究,认为在雷击线路时,会产生感应过电压,反击过电压和雷击导线过电压。感应过电压的耐雷水平约为86kA;反击过电压的耐雷水平约为(21￣28)kA;雷击导线过电压的耐雷水平约为2kA。提出通过架设线路型无间隙避雷器和线路型空气间隙避雷器来提高线路的耐雷水平,通过一个雷雨季节的验证,防雷效果十分明显。

| Abstract: | It's not satisfactory for using only distribution type arresters to protect electrical equipments in the Shengli oil field.After analyzing the over voltage of 6 kV and 1 140 V transmission-line,it is considered that inductive over-voltage,back flashover voltage and over-voltage due to straight thunder strike on conductor might be induced.The withstand level for inductive over-voltage is about 86 kA,for back flashover over-voltage is(21～28) kA,and for over-voltage caused be thunder strick onto conductor is 2 kA.The lightning protection leavel of the transmission line was enhanced by installing line type MOAs with and without spark gaps both which was proved during a thunder season. |
