Description
Technical field
The present invention relates to cable duct of substation water-level alarm equipment technical field, particularly to a kind of substation cable ditch-water
Position monitor and alarm system and monitoring method.
Background technology
At present, there is problems with in cable duct of substation.1, transformer station carries out unmanned, and a centralized control center monitors
It is local that much transformer stations, and transformer station are both dispersed in each.Check that workload is big flood season.2, at thunderstorm season, the most right
The cable duct at each station carries out inspection of flood defense, and is also performed to other and checks, and the cable duct distribution at each station is a lot,
Check one by one, so considerably increase workload and the working time of staff, too increase working strength, affect work
Efficiency.3, warning reminding can not monitor personnel during cable duct infiltration at ordinary times, only just can pinpoint the problems routine inspection when,
So there is also the biggest potential safety hazard.Generally speaking, existing cloud is embroidered cable duct of substation and is distributed in full station everywhere, although have water level
Observation station, but cable channel cover plate everywhere have to be opened respectively, use visual method to observe.The only just meeting when special tour
Checking one by one, monitoring at ordinary times can not reach all the period of time, it is impossible to finds in time when going wrong to report to the police.Transformer station female person on duty exists
Open cable duct and there is strength deficiency, injured.Occur that the reason of above-mentioned phenomenon is: substation inspection is substantially by manpower
Range estimation, and artificially judge to check again according to factors such as weather.The news phase checks that workload is big, if the rainy day renovates plate, easily
Cause injury to personnel.Monitoring shortage of manpower, new technology of not being correlated with carries out substituting personnel inspection.
CN201220326651.6 discloses a kind of cable duct of substation water level remote alarming device, including water level switch,
Data source, data sink and siren, described water level switch is connected by wire and described data source, described number
It is connected with described alarm by wire according to receiver.Owing to the utility model arranges water level switch in cable duct, water level is opened
Closing and connected by wire and described data source, data source arranges switch, be used for preventing water level too high, data are launched
Device is connected for a long time, makes the damage of twin installation, avoids system to connect for a long time, can be also used in disconnection institute beyond flood season simultaneously
State switch, extension device service life.Waterproof rubber sleeve is set outside data source, it is possible to prevents rainwater from immersing data and launches
Device causes line short, and data sink is connected with described alarm by wire, and person on duty can supervise in night shift room in real time
Measure cable duct water level.And for example CN201310600403.5 discloses a kind of electricity substation cable duct water level detecting warning dress
Putting, including the high water level detecting head being arranged in cable trench and low water level detecting head, the position of low water level detecting head is less than height
The position of water-level detecting head, wherein, low water level detecting head connects low water level sender unit, and high water level detecting head connects height
Water level signal transmitter, low water level sender unit and high water level sender unit carry out wireless company with monitor controller simultaneously
Connect.It is disadvantageous in that: above-mentioned water-level detecting head is installed in cable duct, has a lot of high-rating generator, transformation in transformer station
Devices etc., the magnetic field that generator, transformer are formed has a strong impact on the degree of accuracy of tester, what is more important above-mentioned water-level detecting head
Being installed under water in precision detection instrument, service life well imagines, general one or two months need to overhaul once, and fault rate rate
Height, 1 year appearance 10 fault several times, and rate of false alarm is high, rate of false alarm is 40%.
Summary of the invention
In view of this, it is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of cable duct of substation water level prison
Observing and predicting alarm system and monitoring method, this system alarm is accurate, and service life is long, uses fault-free for a long time.

From embodiment 2,3,4, the rubber rope that embodiment 2,3,4 prepares all can meet the demand of transmission of the present invention, more
For it is important that do not affect the rise and fall of impeller；Its main cause is, the formula of the present invention adds appropriate zeolite
Powder, zeolite powder hollow structure makes the density of rubber, and close to the density of water, (the rubber density of rubber rope formula 1,2,3 system are respectively
0.97g/cm³、0.999g/cm³、1.09g/cm³).The present invention uses special rubber rope, and it is upper and lower that rubber rope softness is easy to slide bar
Mobile, the radial direction torsion of rubber rope is big simultaneously, it is possible to make wheel rotation drive rubber rope to rotate, and then rubber rope drives drive shaft
Rotate, it is ensured that brush body rotates to be easy to clean filter bores；The density of what is more important rubber rope is close to the density of water, at Shui Zhongchu
In suspended state, do not affect moving up and down of impeller, thus ensure that the lower half of impeller is positioned at the water surface in real time, and then ensure water
While flowing, impeller rotates, and the machine driving of the present invention, and in 1 year, rate of false alarm is zero after tested, fault-free；Adopt
Using rubber rope of the prior art, rubber rope easily sinks in water, affects transmission performance, what is more important prior art
Softness and the radial direction torque forces of rubber rope are not enough, it is impossible to meet the demand of transmission, and the rubber rope of prior art is not durable,
Testing through inventor, under identical torsion, rotate the identical number of turns, the rubber rope of prior art tests 1000 just fractures, and
The rubber rope test using the present invention is not the most ruptured for 10000 times.
Finally illustrating, above example is only in order to illustrate technical scheme and unrestricted, and this area is common
Other amendment or equivalents that technical scheme is made by technical staff, without departing from technical solution of the present invention
Spirit and scope, all should contain in the middle of scope of the presently claimed invention.
