Commodity: HKHB-608 SERIES INTELLIGENT ARC LIGHT PROTECTION DEVICE

Application Scenarios: Used in the protection for smart utilization of electricity in the field of electric power,petrochemical,metallurgical and other industries

Product Overview

Specially designed according to the protection characteristics of  the medium and low voltage bus system,which can effectively prevent and reduce the harm of arc light,the system adopts the double criterion principle of arc detection and over current detection,fast action,high reliability,no special requirements for primary equipment.The device breaks through the problems of selectivity ,sensitivity,and gradation in conventional protection.It is simple to use,has a wide range of

Protection ,and has no special requirements for primary equipment,and has strong economic practicability.

The action time of the HKHB-608 arc optical bus protection system is 7-10ms,which is much faster than the traditional bus protection,and the short-circuit fault removal time in the switch cabinet can be controlled within 100ms.Therefore,this protection system can minimize the failure loss and create conditions for the rapid handling of accidents and the restoration of power supply.
