| 什么是零序电流互感器： What is a zero sequence current transformer (zero sequence current transformer): 零序电流互感器是用于电力电缆上的一种互感器，它的一次绕组为穿过互感器内孔的三相一次导体电缆（或是单相电缆），它的一次电流是一次三相电流的矢量和（在三相平衡时为0），当发生系统单相接地时或三相平衡时，矢量和不为0，零序电流互感器的二次有电流输出，可以供给保护装置，实现保护和监控。 Zero sequence current transformer is a transformer for power cable and its primary winding of three-phase transformer through the inner hole of a conductor cable (or single-phase cable), a current which is a three-phase current vector and (in phase equilibrium is 0), when the system single-phase grounding or three-phase equilibrium, and the vector is not 0, the zero sequence current transformer two current output, can supply protection, protection and monitoring. 由于电缆自身绝缘，零序电流互感器外壳也是绝缘的，所以零序电流互感器可以使用在任一电压等级的电缆上。 Due to the insulation of the cable itself, the zero sequence current transformer shell is also insulated, so the zero sequence current transformer can be used on any cable of any voltage level. |
