Abstract

Fire emergency lighting power switching devices play a crucial role in ensuring the normal operation of emergency lighting equipment when a fire occurs. This paper conducts an in-depth analysis of the reliability of such devices, exploring the potential fault types they may encounter in a fire environment and their impact on system performance. It analyzes the working principles, common faults, and causes of currently used switching devices. Combined with failure modes in practical applications, it proposes several improvement measures to enhance device reliability. By comparing the performance of different types of switching devices, it suggests directions for optimized design to ensure the effectiveness and stability of fire safety facilities in emergency situations. This study provides a theoretical basis and practical reference for improving the reliability of fire emergency lighting power switching devices.
