Functions and Roles of Arc Fault Detection (AFD) Electrical Fire Detectors
In China, over 30% of annual fires are directly caused by electrical fires. According to authoritative national statistics, electrical fires triggered by short circuits and arc faults rank highest among all fire categories. Therefore, Arc Fault Detection (AFD) Electrical Fire Detectors address the root cause of electrical fires by detecting fault arcs in power distribution lines and electrical equipment resulting from short circuits and poor connections. When predetermined conditions are met, the system immediately interrupts the fault arc and triggers an alarm, effectively controlling electrical fires in their incipient stage.
The widespread application of these detectors will bridge technological gaps in existing electrical fire monitoring systems and eliminate blind spots in electrical fire hazard detection. These products are extensively suitable for fire early-warning systems in residential buildings, civil constructions, factories, internet cafes, warehouses, schools, and other structures.
The BMF-AFD32A Arc Fault Detection Electrical Fire Monitor, developed by our company as part of China's 12th Five-Year Plan national research initiative, represents our first-generation innovative product. Its design complies with the GB14287.4-2014 standard and incorporates internationally advanced arc fault identification technology. Additionally, we have developed a proprietary arc fault recognition algorithm tailored to China's application environment, which has been granted a national invention patent.
Furthermore, the detector employs an advanced CAN bus communication solution, enabling direct connectivity with electrical fire monitoring equipment. Alarm signals are transmitted in real-time to the monitoring system. With these cutting-edge technologies, the product achieves industry-leading performance and technical sophistication.
Product Features
- Precisely distinguishes between normal arcs and fault arcs on each phase line;
- Can be connected to a shunt trip device—when the detector identifies a fault arc, it triggers the shunt release to cut off the faulty power supply.
- Utilizes an advanced CAN bus communication solution, enabling immediate upload of alarm data with minimal delay;
- Upon fault arc occurrence, transmits the location data of the fault point to the monitoring equipment, enabling precise fault zone localization;
- When a fault arc is detected, activates an integrated visual alarm indicator and simultaneously sends an alarm signal to the monitoring system.
- Precisely distinguishes between normal arcs and fault arcs on each phase line;
