Abstract

Abstract: This paper introduced the main causes of subway electrical fire and the necessity of early monitoring to prevent subway electrical fire, put forward the pyrolytic particle electrical fire monitoring technology in subway, and studied and analyzed the application of DT-300/RJ fire detector in subway. The research shows that the detector can reduce the false alarm and missing alarm of subway electrical fire, improve the electrical fire monitoring system, and ensure the safe and reliable operation of subway electrical equipment.

Key words: subway, electrical fire, pyrolysis particles, fire detector
