Product Description

Product Description

Functions of the controller
1. Quick break protection 2. Overcurrent protection 3.Triple reclosing event recording 4. Surge protection
5. Zero sequence protection 6. Real time clock 7. Acceleration after reclosing 8. Real time status query 9. Intelligent handheld computer control

10. Local/remote setting constant value QGPRS communication
Characteristics of the controller
1. Can be equipped with 485/232 communication interface, or achieve remote monitoring through fiber optic or wireless; The acceleration function after reclosing automatically accelerates and trips when the switch recloses to a permanent fault;
2. Remote control/manual closing accelerates tripping and locks for re closing: After the user inspects the circuit and sends power, if the connection is forgotten to be removed
The ground knife switch should be tripped quickly; The delay time of the Q triple reclosing can be adjusted: the Q tripping and closing circuit adopts anti misoperation design and has anti tripping function. The zero sequence current can distinguish faults within and outside the zone; The remote control switch adopts a design to prevent misoperation. structural characteristics
a) The controller is a microcomputer based relay protection and monitoring device:
b) The controller has strong weather resistance and anti condensation protection characteristics: c) It is connected to the switch body through aviation connectors, d) The connection reliability is good and the protection level is high. There are four analog input channels for the controller, namely A-phase current, C-phase current, zero sequence current, and BC phase voltage. The controller determines line faults by monitoring the values of the analog quantities in real time and comparing them with the fixed values, and then takes corresponding actions. The following table shows the fault handling results for different systems.
