标准摘要
[中文适用范围]: 该标准专门适用于反应堆安全壳内的电缆贯穿件(文中称为“污染物”)。它涵盖了电缆贯穿件的设计@计算@制造@组装@测试@安装和维护中要满足的工程安全要求电气贯穿件通过一个或多个电路的安全壳提供气密和耐压穿透。就本标准而言,电气贯穿件包括: - 直到安全壳内和外最近连接点的电导体(贯穿导体) ); - 用于此类导体的电气绝缘的部件; - 用于该导体组件的耐压、气密和耐温外壳的部件以及用于与安全壳壁连接的部件: - 用于监测气体泄漏的永久连接装置。不属于电气贯穿件的一部分包括: - 用于连接贯穿件@的安全壳壁的部件,例如用于螺栓连接或管道连接的密封表面或需要焊接的喷嘴; ——连接到穿透导体或连接器的电缆和线路; - 端子元件@,例如连接到所连接的电缆或线路的电缆接线片或端子@或焊接套管; - 泄漏测试或排气装置暂时连接到贯穿处。连接到穿透组件或安全壳结构的外部电路的要求超出了本标准的范围。” [外文原描述]: Applies to cable penetrations in reactor containments. Covers the engineered safety requirements to be in the design, calculation, fabrication, assembly, testing, installation and maintenance of cable penetrations. Describes the requirements for the design, construction, test and installation of electric penetration assemblies in nuclear containment structures other than the primary pressure envelope for power generating stations. Electric penetrations provide gas-tight and pressure-resistant penetration through the containment of one or more electrical circuits.
