ZW32-24型自动重合器其额定最大连续电流为630A，对称开断额定值为16KA。是电站或柱上安装的户外开关设备。主要用于额定电压12KV、24KV和40.5KV,三相交流50HZ输配电系统中额定电流的开合以及三相三次重合闸，过负荷保护，三段式过流保护，三段式零序电流保护，失压保护，同时具有故障录波，小电流接地选线功能。其中三段式过流保护通过方式字可选择经低压闭锁或经方向闭锁。重合闸有检无压和检同期功能。产品设有RS232及LONWORKS通讯接口可与监控系统连接，便于实现四遥及远方通讯，定时全面的自检系统大大提高了配电系统的可靠性。
The rated Max. continuous current of ZW32-□Z type automatic re-closer is 630A,symmetrical breaking rated value is 16KA.It’s a kind of power station or pillar install outdoor switchgear. It is main used for making and breaking rated current in transmission and distribution power system of three-phase A.C,50HZ,rated voltage 12KV,24kv and 40.5kv,and three phase thrice re-closing, over load protection, three
Phase zero sequence current protection ,lose voltage protection. At the same time,
It has function of record fault wave, little current earthing optional line. Its
three phase over current protection pass mode can chose through low voltage lock or through direction. Re-closing can check no voltage and check the corresponding period. The product has RS232 and LONWORKS communication adapter, can connect with inspection system, so to realize distant communication, the timing self check system greatly increase reliability of power distribution system.
