SFZCW Series Intelligent Recloser Controller
As a kind of feeder automation-remote terminal unit (FA-RTU), the SFZCW series intelligent recloser controller is mainly used for 35 KV (or lower) power distribution network. It can protect and monitor the network and some facilities on it, making itself a necessary device for protecting and controlling the pole mounted recloser switch.
The product comes with a LCD screen and stepless parameter setting property. It has many protective functions, such as overcurrent protection, quick-breaking and reclosure, for the power supply network. The features include high precision, great anti-disturbance capability. Typically, our product can help the system to avoid the inrush current of the transformer, enhancing the sensitivity and reliability of the quick-breaking function. Thus we can eliminate the influence of instant faults, as well as isolate the fault sections permanently. The power failure range will be narrowed and the power supply stability will be improved.
The SFZCW series intelligent recloser controller has four types of communication functions, namely by cable, light, GPRS, GSM. If communication line is available, our product can provide on-line functions like reading testing data, setting and checking fixed values, remote control of closing and opening, and so on, laying the foundation for the automation of the power distribution system.
