Building electric fire hidden trouble alarm power distribution method and its circuit

Abstract

The present invention discloses a building electric fire hazard alarm distribution method and circuit. It contains all breaker having short circuit, overload and electrical leakage ternary protection and auxiliary contact output, connecting auxiliary contact of each breaker to alarm control circuit, when electric fire hazard occurrence circuit simultaneously sending audible and visual alarm signal and indicating out concrete position. The present invention has simple structure, easy maintenance, higher operational reliability, and convenient centralized monitoring advantages.

Description

technical field [0001] The invention relates to an alarm circuit for electrical fire hazards, in particular to a power distribution circuit for alarming electrical fire hazards in buildings. Background technique [0002] According to statistics, among the total number of fire hazards in our country, electrical fire hazards account for 30% of the total number of electrical fire hazards, and account for the first place among the causes of fire hazards. Most electrical fire hazards are caused by short circuits, especially arcing short circuits to ground. Due to the great danger of electrical fire hazards in buildings and the dense population, it brings a lot of inconvenience to the fire fighting work, especially the buildings are getting higher and higher now, and the fire fighting work is also more difficult. Therefore, the country stipulates in the 2005 edition of "Code for Fire Protection Design of High-rise Buildings" that high-rise buildings must be equipped with leakage ...

AI Technical Summary

Problems solved by technology

Although circuit breakers are installed on each type of load, these circuit breakers usually only use circuit breakers with short-circuit protection or overload protection functions, which cannot be connected with existing conventional alarm circuits, and it is difficult to achieve centralized monitoring and electrical fire protection. Automatic alarm for hidden dangers; however, the existing automatic alarm distribution system for electrical fire hidden dangers in buildings generally has the disadvantages of complex structure, large investment, high operating costs, and difficult maintenance

Therefore, when the existing power distribution technology for building electrical fire hidden danger alarm is in use, its use effect is still not ideal.
