石油钻机系统是一个复杂的小电网系统,它既有作为动力源的发电系统,又有驱动动力系统,三相交流用电设备、照明设备。由于其野外作业、频繁移动的特点,要根据设备的主要使用地域,合理的设计供电方式和漏电保护器,同时辅助绝缘监视仪,提高系统的安全性和完善保护功能。在现代石油钻机设备中,IT、TN-C、TN-S的复合供电方式已经成为主要供电模式。
Oil rig system is a complex small power grid system, which has both as a power source generating system, but also drive power systems, three-phase AC power equipment, lighting equipment. Because of its field operations, the characteristics of frequent movement, according to the main areas of use of equipment, reasonable design of power supply and leakage protector, at the same time auxiliary insulation monitor, improve system security and improve the protection function. In the modern oil rig equipment, IT, TN-C, TN-S composite power supply has become the main mode of power supply.
