Description
Technical field
The present invention relates to a kind of system and laying method thereof, particularly relate to a kind of transformer station cable early warning and fire-fighting integrated system and laying method thereof.
Background technology
Economic growth makes power system fast development, and increasing transformer station puts into operation.The various cables that lay in transformer station comprise a large amount of high-voltage power cables, low voltage control cable and optical cable for communication etc., are distributed in cable duct, crane span structure, vertical shaft, interlayer etc. and locate, and each electrical equipment is connected into one.Due to the restriction in place, power cable and control cables cannot divide ditch to deposit in transformer station.The fire prevention measure that adds these positions is simpler, residing environment is mostly poor, and the cable closeness in part place is high, operation maintenance difficulty, various places Cable Firing Accident happens occasionally, have influence on the safe operation of electrical network, or cause large stretch of user's short time load loss, or cause even casualties of economic loss.
Cable is safe operation under conventional operating mode; but internal factor impacts such as being subject to end fault, moving that insulation ag(e)ing, long-term running overload or protection (switch) device can not excise in time for a long time, the quality of cable own or mounting process do not pass a test; or in external force mechanical damage, because of insulation breakdown short circuit, lay under the external factor effects such as defect, other foreign material be on fire; can be because of overheated its external insulation layer that ignites of local moment; and along cable propagating combustion; from a regional diffusion to another region, lead to a disaster.Cable interlayer, cable duct, cable shaft on fire proportion in transformer station's fire incident is very large.
In transformer station, the multiple laying cable environment such as mainly comprise between cable duct, cable testing bridge, cable shaft, secondary device chamber interlayer, private cable.Cable has different operating modes in zones of different, thus its ignition factor and propagation of flame situation and harm all not identical.

Cable testing bridge operated by rotary motion is at top, 10kV switch gear room, and cable is closed in can, and object of protection is single and distance is not long, belongs to unattended region, in the time of detection and the choosing of means of fire, need to consider small space problem.
Cable shaft is for connecting two regions of Different Plane height, as between 10kV switch gear room and GIS chamber, between 10kV switch gear room and secondary device chamber.The space of cable shaft is sealed, and belongs to unattended region.Vertical shaft can produce " stack effect " flue gas that upwards stretches in the time having the condition of a fire to occur, and therefore can not adopt gas extinguishing agent.
Secondary device chamber cable interlayer generally, at the built on stilts high about 0.3m of secondary device room floor place, seals with refractory plasterboard on it, and space is sealed.Meanwhile, secondary device chamber generally doubles as control room and uses, and belongs to and has people's operating area, more should consider emphatically the security implication to operating personnel in equipment protection.
Consider above-mentioned factor, at present more single to the surveillance and control measure of transformer station's cable, can not within the scope of all fronts, day and night monitor, more there is no the firefighting monitoring system for cable laying regional characteristics specially, can not control timely and effectively Cable Firing Accident or the potential safety hazard in its running.Therefore, cable comprehensive survey, early warning and the fire-fighting system in the urgent need to arranging for transformer station's zones of different feature, improves fire alarm and the fire-fighting effect of transformer station at present.
