The IVL-AR intelligent arc protection system is a new generation of intelligent arc protection products developed by our company on the basis of long-term power automation product design and development, introducing foreign advanced technology concepts and combining the actual use habits of domestic users.
The IVL-AR intelligent arc protection system is composed of IVL-AR-M series bus arc protection device, IVL-AR-FP feeder protection device, IVL-AR-MC arc expansion unit and IVL-AR-UP ultraviolet arc detector. IVL-AR intelligent arc protection system adopts arc and protection current and zero sequence current criterion, which has the characteristics of high reliability and fast protection action (the total time of the device exit is less than 5ms, and the total time of fault removal can be controlled within 75ms), It can significantly shorten the removal time of the arc light fault, reduce the damage of the arc light to the equipment, reduce the equipment outage time, can restore the power supply faster, and can greatly reduce the damage of the arc light to the person.

IVL-AR-MC arc expansion unit
If the arc light measurement port of the main control unit is not enough, or if you want to set more trip logic, you must use the arc light extension unit. The IVL-AR-MC arc expansion unit developed by our company can connect up to 16 arc detectors, which can meet the requirements of various applications.
