SYSTEM OVERVIEW
The electrical fire monitoring system detects the residual current (leakage current) and temperature value in the power distribution line. When the leakage current increases or the temperature exceeds the normal range due to the fault of the monitored line, for example, insulation deterioration, the detector collects the value, reports the alarm information to the electrical fire monitoring system through the bus, and displays the leakage current, temperature, and alarm location. It can effectively prevent the fire hazard due to the slow temperature rise of the inter-line terminal or line, or the increased leakage current. As an independent and newly developed electrical fire monitoring system, the TY-DQ series electrical fire monitoring system well integrate the leading bus, power electronics, computer, communication, and simulation technologies. It is advantageous in real-time centralized monitoring and features high reliability, high sensitivity, fast response, and large memory storage capacity. It can also be a part of the power distribution automation system and fire protection system to facilitate user management and monitoring. It can be widely used in urban rail transits, transportation hubs, exhibition halls, hospitals, shopping malls, factories, schools, hotels, underground spaces, and urban complexes.
SYSTEM COMPOSITIONS
The system is composed of TY-DQ-300 electrical fire monitor, several TY-SY3W-Z08 residual current electrical fire monitoring detectors, TY-SY3-Z44 combined electrical fire monitoring detectors, and TY-SY3-Y41 residual current electrical fire monitoring detectors, which can form a monitoring network through two-bus.
