The invention solves the problem that in normal times, monitoring personnel cannot be warned in case of water seepage of the cable trench.
Description
Technical field
The present invention relates to the electricity substation cable duct water level detecting warning device in power equipment, problem that can not warning reminding monitor staff when this system can solve the infiltration of cable duct at ordinary times.
Background technology
At present, there is following problem in cable duct of substation.
1, transformer station carries out unmanned ，Yi Ge centralized control center and is monitoring a lot of transformer stations, and transformer station is all dispersed in each place.Check that workload is large flood season.
2, at thunderstorm season, to to the cable duct at each station, carry out inspection of flood defense respectively, but also to carry out other inspections, and the cable duct at each station distributes a lot, to check one by one, the workload and the working time that have so greatly increased staff, also increased working strength, affects work efficiency.
3, in cable duct when infiltration, can not warning reminding monitor staff at ordinary times, only in routine inspection, just can pinpoint the problems, so also the very large potential safety hazard of existence.
Generally speaking, existing cloud is embroidered cable duct of substation and is distributed in full station everywhere, although there is water-level observation point, must open respectively cable channel cover plate everywhere, uses visual method to observe.Only when special tour, just can check one by one, monitoring at ordinary times can not reach all the period of time, can not when going wrong, find in time to report to the police.The female person on duty of transformer station exists strength not enough opening cable duct, easily injured.
The reason that occurs above-mentioned phenomenon is: substation inspection is substantially by manpower range estimation, and artificial judgement checks again according to factors such as weather.The news phase checks that workload is large, if the rainy day is renovated plate, easily causes injury to personnel.Monitoring shortage of manpower, not relevant new technology substitutes personnel inspection.
Summary of the invention
The object of the present invention is to provide a kind of electricity substation cable duct water level detecting warning device, problem that can not warning reminding monitor staff while solving the infiltration of cable duct at ordinary times.
Object of the present invention is achieved through the following technical solutions: electricity substation cable duct water level detecting warning device, comprise the high water stage detecting head and the low-water level detecting head that are arranged in cable trench, the position of low-water level detecting head is lower than the position of high water stage detecting head, wherein, low-water level detecting head is connected with low-water level sender unit, high water stage detecting head is connected with high water stage sender unit, and low-water level sender unit and high water stage sender unit and monitor controller carry out wireless connections simultaneously.
In order to address the above problem, the present invention is specific arranges warning system according to said structure, to improve cable duct monitoring water level efficiency in flood season, realization reaches certain value alarm in each cable duct of substation water inlet and water level, remind monitor staff, and on monitoring panel the transformer station of display alarm and the objects such as details of position, make cable duct water level monitoring warning system.Make monitor staff reach the spot and to take measures rapidly.Improve the safe reliability of power transformation operation work.
In all cable duct lowest water level observation stations, low-water level detecting head is installed.Low-water level detecting head can reach a certain height and realize warning function at water level.In all cable duct peak level observation stations, high water stage detecting head is installed, high water stage detecting head is realized high water-level alarm.
Monitor controller passes the signal on the monitor screen that main control room is corresponding.
Monitor screen is uploaded to data-switching in Surveillance center's supervisory system, to reflect real time water level height.
After arranging like this, after rainwater or generation percolating water, in cable trench, suffer after foreign matters from being blocked, will certainly cause the water level in cable trench to go up, when water level touches after high water stage detecting head and low-water level detecting head, realize the forwarding of water level information, water level information is forwarded to after monitor controller, get final product real-time demonstration water level information, now operator on duty can determine whether that setting out fault gets rid of group according to water level information, and arrived call cable groove is processed the foreign matter or the ponding that cause in cable trench.Can also in causing cable trench, add holding water pump, can realize instant Long-distance Control draining means, needn't need personnel to arrive at site disposal.
Preferably, high water stage detecting head and low-water level detecting head are mechanical type level detecting device or electronic type level detecting device.
Monitor controller is PC monitoring equipment.
Also be connected with alarm.
Alarm is audible-visual annunciator.Audible-visual annunciator can be realized warning effect, if scene has operator on duty to exist, and handling failure timely.
Preferably, low-water level sender unit and high water stage sender unit are radiofrequency signal generating means.
Preferably, high water stage detecting head and low-water level detecting head are LC-SW1 type level sensor.
The invention has the advantages that: can solve Realtime Alerts and process, and by remote control water pump, can realize remote failure and get rid of, after cable duct water level alarm system has been installed, greatly alleviate the workload of operator, and improved the accuracy to cable duct water-level observation.Improved cable reliability of operation.
