A kind of low-tension switch cabinet divide-shut brake remote control executing agency
Technical field
The present invention relates to power distribution automation installations and facilities technical fields more particularly to a kind of low-tension switch cabinet divide-shut brake to be remotely controlled
Executing agency.
Background technique
With the propulsion of the third time industrial revolution, electric power will occupy increasing specific gravity in energy consumption mix.By
In the scarcity of power Transmission resource, electric system has natural monopoly, and electric system has the characteristics that many exclusive.Electricity
Force system is one of artificial industrial network system most complicated in the world.Relative to telecommunications enterprise, electric system coverage area is more
Extensively, possess more accessing users.Big and small equipment, household electrical appliances access electricity by each voltage class in all kinds of power consumers
Net.Therefore, power grid has potentiality and possesses most true, widest data.
Compared with traditional mass data, big data have " 3V " feature, i.e. Variety (data type diversity),
Volume (data magnanimity) and Velocity (data processing speed requires high).The big data of electric system not only has big data
" 3V " feature, also there are other " 2V " features: Veracity (accuracy is high), Value (value is high).
It is further pushed away with urbanization, the raising of the level of IT application and novel Urbanization Construction with advances in technology
Into smart home, intelligent building, intelligent Community, intelligent city all will be as developing direction from now on, family distributed hairs
Electricity, electric car, intelligent appliance etc. will also promote and apply.In smart grid, intelligent power plant, intelligent substation and smart home
Digitizer integrated level is higher, compatibility is stronger, the data volume for generating it in operational process is bigger, data precision more
Height, to equipment operation maintenance work, more stringent requirements are proposed for this, and traditional data analytical model is no longer satisfied intelligent electricity
Digitizer mass data processing demand in net.
Substation (Substation) is that some equipment are assembled, to be switched off or on, change or adjust electricity
Pressure, in the power system, substation is the assembly place of transmission and disttrbution.And low-tension switch cabinet is indispensable one in substation
Kind distribution switchgear, transmission and control for electric energy.Generally, the behaviour for the master switch facility being equipped with inside low-tension switch cabinet
Make to realize the movement of switch using electric operation button, for example, on the cabinet face of 380V switchgear with operating breaker separating brake,
The switch button component of combined floodgate.The divide-shut brake of low-tension switch cabinet is to carry out people to scene by operation maintenance personnel in standing in substation at present
The mode of work operation, which need the professional ability of personnel strong, are familiar with electric wiring, and human cost is higher, work
Low efficiency, automatization level are low.It is more and more various that automation means are introduced with the development of Distribution Automation Technology, in substation
Change, study carefully its purpose is to mitigate the action of manpower, save human cost, use is more scientific, and more professional automation means are real
Show the unattended target of substation, and the automation control data of substation are included in the data processing system of smart grid.
