Electric fire supervisory system: Should be explored in circuit by protection when parameter exceeds set to be worth, can give out signal of alarm signal, control to be able to be indicated call the police the system of place, it is comprised by detector of monitoring of electric fire supervisory equipment, electric fire.
Detector of electric fire monitoring: Explore be waited for by the odd electric current in protective route, temperature the detector that parameter of electric fire hazard changes.
Electric fire supervisory equipment: Can receive the alarm signal that comes from detector of electric fire monitoring, can issue sound, smooth alarm signal and control signal, the directive calls the police place, record and save call the police the device of information.
” of “ leakage of electricity in the world current term is ” of “ odd electric current, other also calls “ the rest voltaic ” about national level, because this is new the standard is uniform call ” of “ leakage of electricity ” of electric current of “ the rest. With this correspondence, " protector of leakage of electricity is installed and move " GB 13955 - 92 also upgrade for " the installation of protector of movement of odd electric current and move " GB13955-2005, carry out since December 1, 2005.
" the installation of protector of movement of odd electric current and move " in it is to the definition of system of fire alarm of leakage of electricity:
Odd cable flow makes electric fire supervisory system: The electric fire that makes with detector of the transformer that monitors odd electric current, odd electric current, warning apparatus or controller is monitored in real time and carry out call the police or the device of dump.
Visible, the detector of supervisory system of GB 14287 electric fire includes type of odd electric current not just detector of electric fire monitoring, still include in recent years new those who appear measure Wen Shi detector of electric fire monitoring. Civil building designs the high level fire prevention standard " GB50045 (2005 edition) in the “ that the system of fire alarm of leakage of electricity that concerned article asks to install is GB13955 definition is odd voltaic movement is electric ” of fire supervisory system, namely only by GB 14287. 2: The electric fire supervisory system that detector of electric fire monitoring makes type of odd electric current.
2, the design of system of fire alarm of leakage of electricity
The pertinent clause that installs system of fire alarm of leakage of electricity is concerned in 2.1 standards
Current, the design of system of fire alarm of leakage of electricity is main according to " civil building designs the high level fire prevention standard " GB50045 - 2005 local edit article: Sex of hazard of the fire inside building of 9.5.1 high levels big, personnel is concentrated wait for spatial appropriate to install system of fire alarm of leakage of electricity.
