The prior art is on petrochemical system long distance pipeline, it is necessary at a certain distance, a valve be installed on pipeline.This
A little valves will not generally fix someone guard, it is necessary to itself possess the ability that judges abnormal conditions.Such as abnormal conditions, valve energy
It is enough automatically closed, while the parameters such as pressure, temperature, internal heat is reached into Central Control Room.These valve monitoring and control systems need one
A little equipment such as sensor, communication apparatus, power module, equipment room are the place for placing these equipment.Briefly, valve chamber is just
It is that valve adds the entirety that transmission control equipment is formed.Valve chamber generally all in the wild, in mountain or gobi depopulated zone, valve are indoor
Core is the shut-off valve on pipeline, other auxiliary devices provide the functions such as power supply, monitoring, signal transmission.Long-distance transport pipes occur
If situations such as accident is either overhauled is, it is necessary to block a part of pipeline section supply, it is necessary to set valve chamber pipeline breaking or point defeated station
Accident, pipeline emergency cut-off can also reduce amount of leakage reduction or emptying amount by valve chamber, so as to reduce loss and danger,
So the construction of long-distance transport pipes must be provided with valve chamber when reaching certain distance by Location class regulation.The load level of valve chamber is not
Can interruptedly supplying power first order load, electric power system must assure that power supply continuity.It monitors valve chamber and generally uses dual power supply, and two
A power supply cannot be damaged simultaneously.When main power source dead electricity or failure, backup power supply is put into immediately as electrical equipment in valve chamber
Power supply is provided.
The patent document of CN201340543Y discloses a kind of pipeline valve chamber remote control system, is made of three parts:Too
Positive energy solar panel, energy supply control module, storage battery power supply unit, RTU acquisition control modules unit, modular converter and communication module
Communication unit is capable of providing big transmission bandwidth.But the significant drawback for inevitably having stability poor.In addition, at present
Valve chamber common scheme is:Dispatch from foreign news agency and UPS combinations power-supply system and independent electric power supply.Dispatch from foreign news agency and UPS combination power-supply systems:Monitoring
When valve chamber location power grid is reliable.Valve chamber power supply using 1 road special line, generally 10kV and standby unit on line type UPS power supply
Mode.Change power distribution equipment is electrically accessed outside 10kV and is converted to low pressure, the input power as ups power is again valve chamber through ups power
Special important load power supply in interior first order load.Ups power is furnished with host and accumulator group.Ups power host uses when normal
Dispatch from foreign news agency is powered for load.When external power failure or dead electricity, the accumulator of ups power puts into power for power load immediately and ensure
The continuity that power load is powered in valve chamber.The preparation time of accumulator should be determined according to external power recovery time in ups power.
Independent electric power supply:It is unreliable or from far-off regions in no power grid to monitor valve chamber location power grid, you can make using defeated medium is managed
For fuel low capacity fuel electric generating apparatus is set also can to use individual solar power supply system according to natural conditions as power supply
Or the generator dress that the power generator that is combined with solar power supply system of fuel electric generating apparatus and solar energy are combined with wind energy
It puts.It is the interface that accumulator charges that the controller of independent electric power supply, which should set and can utilize dislocation generation equipment, and can be passed through
Communication interface uploading system parameter, integrated alarm and battery capacity alarm signal etc..Two kinds of power supply modes described above it is notable
Shortcoming is:The stability of independent electric power supply is not as good as dispatch from foreign news agency and UPS combination power-supply systems.And use dispatch from foreign news agency and UPS combination power supplys
The UPS unit components used in system are more, and cost is expensive, and not only cost is high for the inverter especially used in UPS units, Er Qie
Belong to the poor component of stability in entire valve chamber system.
