Automatic fire alarm system for GIL pipe gallery

Abstract

The invention discloses an automatic fire alarm system for a GIL (gas insulated metal enclosed transmission line) pipe gallery, and relates to the technical field of high voltage transmission and firesafety, which can effectively cope with the occurrence of fire inside the GIL pipe gallery, thereby avoiding loss of life and property due to fire. The fire automatic alarm system includes: a plurality of fire detection and alarm units corresponding to all the sub-control centers in a one-to-one manner, and a main control platform disposed outside the GIL pipe gallery. Each fire detection and alarm unit includes an alarm controller, and a fire sensing device and a fire alarm device which are signally connected with the alarm controller; the alarm controller is disposed in the corresponding sub-control center, and the fire sensing device and the fire alarm device are disposed a pipe gallery partition corresponding to the sub-control center. The main control platform is signally connected to all the alarm controllers. The automatic fire alarm system is used for fire alarm of the GIL pipe gallery.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission and fire safety, in particular to an automatic fire alarm system for a GIL pipe gallery. Background technique [0002] Gas Insulated Metal Enclosed Transmission Line (GIL for short) usually includes insulating pots, conductors and other equipment, all of which are directly or indirectly sealed in the pipe tree composed of metal pipes and casings, and the pipe tree Each pipeline is filled with a certain pressure of sulfur hexafluoride (SF 6 ) insulating gas. [0003] The GIL pipe gallery is a tunnel space built underground with GIL installed. It uses GIL to transmit large-capacity UHV current, which is convenient for realizing the closed-loop operation of the cross-regional UHV AC ring network. Due to the long span of the GIL pipe gallery and the relatively closed internal space of the GIL pipe gallery, once a fire hazard occurs inside the GIL pipe gallery, the consequence...

AI Technical Summary

Problems solved by technology

[0004] However, there is no automatic fire alarm system suitable for GIL pipe gallery at present. If there is a fire inside the GIL pipe gallery, it can only rely on the operators inside the GIL pipe gallery to call the police and take fire-fighting measures after discovering the fire

However, if the workers inside the GIL pipe gallery discover the fire, the fire is already serious, then the occurrence of the fire will be inevitable, and it will easily cause huge loss of life and property
