Description
Technical field
The present invention relates to a kind of skid valve chamber device, particularly relates to a kind of long distance pipeline valve chamber equipment that is used for and uses
Skid valve chamber device in room integrated programme.
Background technology
, it is necessary at a certain distance, a valve be installed on pipeline on petrochemical system long distance pipeline.These valves one
As will not fix someone guard, it is necessary to itself possess the ability for judging abnormal conditions.Such as abnormal conditions, valve can close automatically
Close, while the parameters such as pressure, temperature, internal heat are reached into Central Control Room.These valve monitoring and control systems need some sensors,
The equipment such as communication apparatus, power module, valve chamber are the place for placing these equipment.Briefly, valve chamber is exactly that valve adds
The entirety that transmission control equipment is formed.
Valve chamber generally all in the wild, in mountain or gobi depopulated zone, the indoor core of valve is the shut-off valve on pipeline, its
He provides the functions such as power supply, monitoring, signal transmission by auxiliary device.
There is situations such as accident or maintenance, it is necessary to block a part of pipeline section supply, it is necessary to set valve chamber, such as in long-distance transport pipes
Pipeline emergency cut-off can also reduce amount of leakage reduction or emptying amount by fruit pipeline breaking or point defeated station accident, valve chamber, from
And loss and danger are reduced, so the construction of long-distance transport pipes must be provided with valve when reaching certain distance by Location class regulation
Room.
The load level of valve chamber for can not interruptedly supplying power first order load, its electric power system must assure that power supply continuity.
Monitoring valve chamber generally uses dual power supply, and two power supplys cannot be damaged at the same time.When main power source dead electricity or failure, standby electricity
Source is put into immediately provides power supply for electrical equipment in valve chamber.
Valve chamber common scheme is at present：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：When monitoring valve chamber location power grid is reliable, valve chamber, which is powered, uses 1 road special line, and one
As for 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, as
The input power of ups power is again especially important load power supply in first order load in valve chamber through ups power.Ups power is equipped with master
Machine and storage battery group.Ups power host uses dispatch from foreign news agency to power for load when normal.The ups power when external power failure or dead electricity
Storage battery put into immediately for power load power, ensure valve chamber in power load power supply continuity.Storage battery in ups power
Preparation time should be determined according to external power recovery time.
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 using pipe
Defeated medium sets low capacity fuel electric generating apparatus also can use single solar energy according to natural conditions as power supply as fuel
The power generator that power-supply system or fuel electric generating apparatus are combined with solar power supply system, and the hair that solar energy is combined with wind energy
Electric machine.The controller of independent electric power supply should set the interface that can utilize that dislocation generation equipment is storage battery charging, and energy
Enough pass through communication interface uploading system parameter, integrated alarm and battery capacity alarm signal etc..
Two kinds of power supply modes described above are applied to long distance pipeline industry spot.Development and alternating current with technology
Popularization and the lifting of stability, 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 with
The UPS unit components used in UPS combination power-supply systems are more, and cost is expensive, and the inverter especially used in UPS units is not only made
Valency is high, and belongs to the poor component of stability in whole valve chamber system.
The content of the invention
For existing valve chamber device technique, it is an object of the present invention to provide a kind of new skid valve chamber device.The device bag
Include valve chamber body and AC to DC unit therein, secondary battery unit, Automatic Control Unit, communication unit, cathodic protection unit and
Light relay unit.
In the AC to DC unit, secondary battery unit, Automatic Control Unit, communication unit, cathodic protection unit and light
It is installed on after unit in valve chamber body, skid valve chamber device is formed together with valve chamber body.The valve chamber body uses multilayer
Insulation antiseptic designs, while for the ease of maintenance, valve chamber body surrounding is all using enabling designing scheme.The AC to DC
Unit is using the high frequency switch power scheme for stablizing high performance-price ratio.The secondary battery unit is by more piece plumbic acid or lead carbon battery group
Into.The Automatic Control Unit detection device and environment working status parameter, and the startup and stopping of control valve indoor equipment.It is described
Backstage outside the indoor state parameter of valve and control parameter teletransmission to valve chamber is received consistency operation instruction by communication unit.It is described
Cathodic protection unit avoids or weakens the generation of metal erosion by applying an impressed current to metal surface.In the light
When unit is used in data remote, the signal received is strengthened to re-emit reinforcement signal again.
The present invention is realized by following operation principle：Electric main is accessed in skid valve chamber when alternating current is normal
AC to DC unit, realizes electric main being converted to stable DC, and realizes oneself into skid valve chamber device
Control unit, communication unit, cathodic protection unit and the power supply of light relay unit.When city's electrical anomaly, from secondary battery unit to automatic control
Unit, communication unit, cathodic protection unit and the power supply of light relay unit.
The skid valve chamber device of the present invention is compact to design, and transport installation cost is low.Surrounding is designed using standard-sized sheet door, convenient
Repair and maintenance, reduces valve chamber floor space, shortens construction period, reduces installation workload, improves system stability, lifting means
Integration degree.
Beneficial effect：Skid valve chamber of the present invention can realize the effective steady operation of long distance pipeline valve chamber equipment, dress
It is simple, practical to install meter, automatization level meets the needs of production run, meets the related specification such as safe and environment-friendly, energy-saving
It is required that.
