Electrical Fire Monitoring System

for Commercial Buildings

As the standard of living in China steadily improves in recent years, there has been a dramatic increase in the use of personal communications devices, computers as well as electrical appliances.  As a result of this life style change, the demand for electrical power in China has also risen considerably.  Unfortunately, this personal improvement has also given rise to the potential danger of electrical fire, directly threatening the safety of people and properties.  In 2008, electrical fire accidents ranked first among all fire incidents in China and accounted for over 30% of total losses.

As an example, ¥700 million RMB has been invested for the construction of a shopping mall with a total floor area of 110,000 m² and a loading capacity of 13-15 MVA.  The shopping mall has 3 internal electrical distribution rooms (external electrical distribution to be determined), 10 LV incoming circuits, 5 tie breakers, 10 capacitor compensation devices as well as 412 LV outgoing feeders and standby circuits.  In order to be successful in the extremely competitive high-end retail space market, the developer attempts to differentiate the value of his property by providing outstanding and comprehensive safety and security services for handling the agglomerative effect in order to satisfy the elevated demands of commercial building developments in newly urbanized cities.  To facilitate the smooth, unconstrained and safe movement of a large amount of people throughout the property and to handle large power consumption with diverse electrical devices, the owner of this large commercial building and the electrical management personnel have brought forward stringent requirements for such aspects as fire safety, security and reliability of power supply, automation level, demand management and energy conservation analysis for the shopping mall’s electrical distribution system.
