High Voltage Automatic Recloser

Outdoor Pole Mounted High Voltage Automatic Recloser

Introduction - High Voltage Automatic Recloser　　
CHZ(Ⅱ)-12/630-20 Outdoor Pole Mounted High Voltage Automatic Recloser (hereinafter refers to the “recloser”) is a three-phase AC 50 Hz outdoorHigh Voltage Electric Componentsequipment. It is mainly used as 10kV side wire outlet and circuit protection switch in urban and rural substations. It can automatically monitor the operations of power transmission circuit and accurately judge temporary failure and permanent failure. It can fix more than 95% temporary failure. The recloser can open and close the switch according to the preset opening and reclosing sequence in the AC circuit as well as automatically reset or lock it. If used with the partition slotter , the system can maximally reduce the power failure range and time without other control system. It is also configured standard RS232, 485 communication interface, four remote control functions which provide powerful support for the full automation of power system.
Functional Features - High Voltage Automatic Recloser
1. Computer control device is configured with a group of 20 batteries. The battery capacity can work for 50-hour.
2. The battery adopts electronic PT, AC220V, CT charge which is safe and reliable.
3. The devices are installed a remote control switch at the distance of 30 meters. The on-site operators need not to climb poles.
4. Provide the protection of management functions. The users can easily modify current skip within a flexible setting value.
