Description
Technical field
Prevent being strayed into monitoring system the present invention relates to one kind, especially a kind of high-speed railway traction substation confined space is anti-error
Enter monitoring system, it may suitable for the traction substation (institute containing AT, subregion institute) of high-speed railway tractive power supply system, switchgear house etc.
Anoxic, SF occurs6The monitoring in the confined spaces places such as (sulfur hexafluoride) occupy-place lowered zones, water logging.
Background technique
Currently, the wide high-speed railway in capital uses many new technologies, new process, but due to monitoring means in actual motion
Single and limitation, is not able to satisfy the related requirement of railway parent company, road bureau's regulation, or even injured the people of on-site personnel
Body safety, is mainly reflected in the following aspects:
1) there is the danger for being strayed into forbidden system；
At this stage, traction substation (institute containing subregion, switching station, AT institute) has been all made of heptafluoro-propane (HFC-227ea) and has gone out automatically
Fiery system, this be it is a kind of based on inhibition, have concurrently physics fire extinguishing effect clean gas fire extinguishing system.Its fire-fighting principle is
When fire alarm occur when, heptafluoro-propane from the gas outlet of tank be discharged rapidly fire alarm occur place oxygen drain and cool down fire alarm hair
At raw, to achieve the purpose that fire extinguishing.That is, system erupt when, if surrounding someone surprisingly swarms into, it will asphyxia or
Frostbite.
Such as on September 23rd, 2015, capital wide high-speed rail Bei Yang village AT automatic fire extinguishing system there have been malfunction problem,
Power supply dispatching notice dispatching desk shows cigarette sense action signal, it is desirable that nets electrician Qu Jinhang and makes an inspection tour, if net electrician is in seven fluorine
Enter in propane automatic fire extinguishing system ejection process, personnel's personal injury will be caused.On September 22nd, 2015, Guangzhou Railway Corporation Guangzhou
4 workers of power-feed section are when Guangzhou south railway station carries out walkaround inspection to cable duct according to plan, because cable duct leads to the water outlet of forced-ventilated well
Mouthful blocking, 1 worker open well lid and go into the well processing, and when dredging, a large amount of toxic gases were gushed out with water flow, and worker asphyxia is caused to be swooned
It is poured on ladder, and there are 2 workers successively to go into the well rescue, due to sucking a large amount of toxic gases, fall in the water of shaft bottom and stop up respectively
Breath, causes 2 workers to die after ineffectual treatment.Lesson written in blood teaches that the monitoring of the confined space is must and should be real-time
, the confined space had been grave danger of upkeep operation safety already at this stage.
2) SF6The cable interlayer in power distribution equipment low level area makes an inspection tour maintenance and jeopardizes personal safety；
There are similar regulation, " high pressure in railway parent company " high-speed railway traction substation trouble free service rule " and each Railway Bureau
Room, cable interlayer inlet should install SF6Gas content display " " enters SF6Power distribution equipment low level area or cable duct carry out work
Work should first detect oxygen content (not less than 18%) and SF6Gas content is no more than 1000ppm ".And these requirements are in current high-speed rail
There are no relatively good means for traction substation.Although portable oxygen-containing tester and SF6Gas content tester can be square
Just on-the-spot test is carried out, but instrument is placed into the confined space and is read containing numerical quantity on condition that someone must be obtained, if
Genuine environment is problematic, that will cause personal injury to placement and reading numerical values personnel.
3) high-tension cable state cannot be grasped in real time；
" Beijing Railway Administration traction power supply high voltage cable management method " requirement, it is " good without ponding, immersion probe state inside cable vault
It is good ".And scene can only lean on " someone's value to the state grasp of on-site cable currently without any water logging remote alarming device is installed
Class electric substation operator on duty is daily to institute's inner cable equipment 1 time ", " unwatched switching station, subregion institute, AT institute, contact net are opened
Close station in high-tension cable equipment monthly 1 time " tour.Making an inspection tour interim, particularly unmanned institute, it would be possible to cause height
It is impregnated in the most 2 months water of voltage cable.For example, Cui Qu, to prolong health cable interlayer ponding that AT just once occurred be more than 60cm
The problem of.
4) situation of device context cannot be grasped in real time；
Inspection, the confirmation of problem above are realized by people, it is necessary to it could check, confirm after waiting personnel to reach scene, once
Confirmation fault, which is perhaps neglected, will lead to the personal injury for checking confirmation personnel or affects adversely optimal troubleshooting opportunity.
To sum up, at this stage, most railway power supply departments scene not relatively good to confined spaces such as cable interlayers
Detection means is strayed into equipment that remote-end alarm is not anti-, also without effective discovery anoxic, SF in real time6Content is exceeded and cable clip
The facility of lamination water, equipment, the operation in these confined spaces are faced with very severe security situation.The above are existing skills
The deficiency of art.
Summary of the invention
Prevent being strayed into monitoring system the object of the present invention is to provide a kind of high-speed railway traction substation confined space, the height
The fast rail traction substation confined space is anti-to be strayed into the requirement that monitoring system meets regulation, can monitor the confined space in real time
Immediate status and teletransmission measured value, automatic far-end alarm and the timely discovery of hidden danger processing, it is ensured that traction substation low level area has
Limit the safety of job space.
