High-rise Complex Building Fire Electrical Design Method And Application

With the rapid development of China’s economic construction, China’s urbanization is leaps, architectural objects growing area, increasing the height of the building, therefore, in recent years, our major fires exposed more and more problems, light by outdoor fire can not meet the rapid fire of the building when the fire requirements, in order to increase the safety and reliability of the building, reducing the loss of life and property, building fire protection design is developing rapidly. The fire was electrical design building design is an important part, as the implementation of fire alarm and fire protection professional electrical brain function is particularly important.In this paper, based on our practical experience, we present an electrical design case of a high building fire safety. The overall design scheme proposed building fire complex electrical system is designed for high voltage 10 KV power distribution systems, generators, UPS, EPS power supply and other firefighting equipment, fire-fighting facilities to ensure two to three power supply, and the power They are away from the nearest distribution box device automatically switch; at the same time, defined the most effective fire power distribution box fire protection measures are to be provided in a small specialized distribution; analysis and comparison of the fire-resistant, flame retardant, mineral insulated three kinds of fire performance cables, use high-temperature impact resistance capabilities and continuous supply ability of mineral insulated wire and fire lighting requirements analysis, design different types of emergency lighting systems, emergency lighting systems to ensure instant and reliable lighting; design automatic fire alarm and fire control linkage system to prevent the occurrence and spread of fire within the building, in order to detect a fire, timely extinguishing of fire and electrical intelligent subsystems were studied, and clearly the future of alarm systems design; and complete the corresponding design of automatic fire alarm subsystems, forming inside a building fire alarm network, network with fire control room as the core, centralized alarm systems linked to information monitoring center, so that the alarm, evacuation, fire prevention, fire extinguishing system can be effectively implemented.
