Description
Technical field
This utility model relates to flood control draining field, is specifically related to a kind of intelligent drainage system.
Background technology
The cable interlayer inner cable of transformer station is densely distributed, bears a high voltage power transmission of the task of power supply
Cable, transmission control and the secondary cable of signal concentrates on this most in a large number.On the one hand cable is to waterproof anti-
Tide etc. requires high, and moist or cable will be caused cable to go mouldy by water logging etc., aging, has a strong impact on
Cable insulation, the terrible consequences such as guiding discharge, short circuit；On the other hand, cable interlayer is normally at
The bottom of transformer station, is easily affected by sleet etc. and hydrops is occurred.Therefore, cable interlayer waterproof,
Draining is particularly significant.In summary, background is as follows:
1., in power system transformer substation, cable interlayer, cable duct are generally lower than the ground level in station,
Although general cable interlayer is designed with catch pit, but occurs hydrops the most most probably in rainy day, snow sky etc..
2. south is with heavy rainfall, particularly spring and summer plum rain season, and time in rainy season length, amount of rainfall are big, electricity
Cable clip layer, cable duct are as easy as rolling off a log, and waterlogging has caused serious damage；And the snow melt in spring in the north also can produce a large amount of melt water and
Make cable interlayer hydrops.
If 3. cable interlayer, cable duct producing more hydrops, by serious threat cable safety, and directly
Connect the safe operation affecting whole system.
4. incompatible with the most fast-developing Substation Automation System.The automation of transformation substations at present
Levels is the highest, fence, fire alarm, and even enclosure wall vibration signal etc. have accessed monitoring the most
Automated system, but, cable interlayer, the hydrops of cable duct and flood thereof etc. are but chronically at
The blind area monitored.
5. currently for cable interlayer, cable duct internal water accumulation, only by security personnel in station or operation people
Member makes an inspection tour could find the long-time hydrops situation that but Nobody Knows even occur.Draining response lag,
Grave danger cable, interior and security of system of standing.
Visible, in substation cable interlayer hydrops, even flood are currently in the blind area of monitoring, sternly
Heavily threaten the safety in production of power system, seriously lag behind growing Substation Automation System.
And known artificial drainage system wastes time and energy, inefficiency, it is impossible to find in real time and process floods.
Chinese patent " the intelligent drainage function of a kind of substation cable layer of Application No. 201120387830.6
System " disclose a solution for the problems referred to above, its drainage system is mainly by level sensor
Device, control chamber and draining water pump composition, can realize the merits such as the automatic alarm of water level, automatically startup draining
Can, the shortcoming of the method is that described drainage system uses single power supply to be that draining pump is powered, reliability
Difference, power supply once breaks down, and drainage system will be caused normally to work, thus impact flood
The adverse consequencess such as phase draining.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome transformer station of the prior art to arrange
The technological deficiency that water system uses single power supply to be draining pump power supply reliability difference, thus a kind of change is provided
The intelligent drainage system of station cable interlayer catch pit, uses dual power supply, it is ensured that hold draining pump
Continuous power supply, it is to avoid single power supply affects the hidden danger of flood control in flood season because long-term work damages.
To achieve these goals, the utility model proposes a kind of intelligent drainage system, including: power supply,
