The electric arc protection system can protect the operators from injury and reduce the degree of property loss in case of arc fault in the switchgear. When an arc appears, the arc bursts at a speed of 300 / s, destroying any material on the way. As long as the system is not powered off, the arc will always exist. In order to reduce the harm of arc, a safe, rapid and effective arc protection system is needed.

        The arc protection device ensures that the power supply switch in the switch cabinet gets the tripping signal in time. If the light signal exceeds the light setting value or the current signal exceeds the current setting value occasionally, the system will not output the tripping signal, but will display the alarm signal on the main control unit. It is necessary to install an arc sensor in each cabinet of the switch cabinet for protection.

        The main control unit of electric arc protection can protect 8 independent switchgear at the same time, and the arc collector can also protect 8 switchgear at the same time. The electric arc protection system transmits the detected arc or current signal to the main control unit. The main control unit collects these necessary data and outputs the tripping signal to the circuit breaker according to the actual situation.
