Description
The application is the divisional application of application number 2014102231180.
Technical field
The present invention relates to electrical power distribution automatization system, more specifically, being to be related to a kind of outdoor switching station, belong to electrical equipment certainly
Dynamicization technical field.
Background technology
Electric system includes power generation, transmission of electricity, power transformation, the several key links of distribution, and wherein distribution is to region be directly facing electric power use
The function at family.In China, the situation of " retransmit, gently supply, is ineffective " is formd for a long time, and distribution network system seriously falls behind, causes
Make that residential electricity consumption line loss is high, voltage is low, power supply is unreliable, become bottleneck of the electric system for electricity consumption.In early stage power grid construction
When, more pay attention to power generation and transmission of electricity, and distribution and electricity consumption link are often little accounted of.Therefore, in recent years, country's input is a large amount of
Fund, by the city and countryside power grid modification of several wheels, has transformed substantial amounts of circuit, switch and transformer etc., has carried out distribution construction.Distribution
As city and the carrier of rural power service, the stability and security of distribution, are directly related to the power supply safety of huge numbers of families,
With important economic value and social effect.With the development of the social economy, the process of electricity marketization deepens continuously, user
Requirement to reliability of electric power and quality is also constantly being lifted, and urban distribution network radius of electricity supply is shorter and shorter, and power distribution network power distribution room obtains
To extensive use.Power distribution network power distribution room is the self-healing of power distribution network and interactive key node, and function list is applied mechanically in power distribution room automation
One " three is distant " monitoring and the construction mode of feeder automation function, it is difficult to meet the demand for development of intelligent power distribution automation.
It is the reply whole world, whole mankind's energy, environment, weather, economy, sustainable and intelligent grid is revolution again of power industry
The comprehensive solution of development, represents the direction of following power grid research and development.Power distribution network is electric energy application, user oriented
Window, be intelligent grid important component, and the intelligentized important breakthrough mouth of power grid.
Power distribution automation refers to be combined with power equipment using hyundai electronics, the communication technology, computer and network technology,
Monitoring, protection, control, metering and the work management of power supply department of the power distribution network in the case of normal and accident are organically melted
It is combined, improves power supply quality, more closely more responsible relation is established with user, meets that user requires with reasonable prices
Diversity, it is best to make every effort to power supply economics.At present, it is to be based on communication network, ca bin and background computer mostly
The electrical power distribution automatization system of network, monitoring power distribution network operation conditions can be also played in power distribution network normal operation and remote control changes
The effect of the method for operation, when failure, can be discovered in time, but lack automatic control function mostly.Even if minority system possesses automatically
Control function, also because system excessively complexity, redundancy so that it is with high costs, be not suitable for promoting and applying.
Before reform and opening-up, most cities are also without the special compact district of load for forming sheet, therefore user's power supply is most
It is that user transformers are directly or indirectly sent to by the 10Kv circuits from substation, distribution system is mainly to set dry fit
Based on radiant type, system connection is simple.But over nearly 20 years, for national economy there occurs change at full speed, city tends to be intensive
Change, urbanization, urban distribution network power load soars, and forms load intensive area, and load density is from original hundreds of kW/km2Increase
Grow to tens thousand of kW/km2, original power supply mode significantly exposes many weakness：Circuit is grown, and line loss is big, quality of voltage is poor；
Troubleshooting situation is complicated；Line facility operation maintenance management heavy workload；Add User dilatation difficulty；Since urban planning will
Ask, construction of line corridor is more and more difficult.Substation line directly arrives this mode of user and is difficult to meet urban development demand,
Thus a kind of new power supply mode was proposed in recent years --- by switching station to customer power supply, these switching stations and substation
Difference be only without main transformer and breaker.On distribution network wiring construction, development trend is supplied using looped network form
Electricity, ring network power supply pattern can improve the reliability of power supply, and user can obtain power supply from switching station's ring-main unit end, reduce
The power failure area of accident.Ring network structure has monocyclic, polycyclic point, also has open loop, the difference of closed loop.According to use function not
Together, monocyclic, open loop operation one second part of distribution network systems can be divided into 5 modules；1) substation's wire-outgoing breaker；2) looped network line
Road；3) loop-network switch cabinet；4) user 10KV power distribution equipments；5) user transformers.According to loop-network switch cabinet, user's 10KV distribution
The various combination of device and user transformers, can form three kinds of loop networks switch station, customer substation and looped network customer substation
Different mode, in these patterns, the main equipment as ring network power supply --- ring main unit, then be increasingly subject to power supply department and
The attention of user.
Ring main unit is that one group of high-tension switch gear is mounted in metal or non-metallic insulation cabinet or makes assembled compartment ring
The electrical equipment of net power supply unit, its basic part as urban distribution network, the security of ring main unit is distribution network feeder peace
The important leverage of full property.In recent years, in urban distribution network, since the accident of power supply that ring main unit failure occurs is commonplace.It is common
Ring main unit failure include switch malfunction, relay fail, external force destroy, switching gas leakage, end fever explosion etc..
It is existing to solve the problems, such as that this effective ways are that distribution automation remote terminal DTU, corresponding communication are installed in ring main unit eventually
End ONU and the Microcomputer Protection and control module that are arranged at the top of ring main unit group are realized.In the prior art to these automation work(
Energy module is divided into distributed frame and centralized configuration.Installation for the automatic function module of distributed frame is divided into two kinds
Mode is installed：One kind is to set this kind of automation function module to inside ring main unit, but has 10000V inside ring main unit
High-tension apparatus, the arrangement space of DTU and ONU are difficult, even if can install, it is also difficult to ensure the operation of complete stability；It is another
Class is that this kind of automation function module is attached to outside switchgear, and any of this kind of automation function module is put, and causes to transport
Row equipment is put messy, and certain influence is brought to maintenance work.It is by this kind of function module independent sets for centralized configuration
In a protective device cabinet, such as a kind of existing cabinet type DTU closed equipments, master control core is provided with the cabinet body of DTU
Piece and the interface being connected with ring main unit Zhong Ge road outlets, by the way that each road outlet of ring main unit is respectively connected to DTU and ONU,
To be monitored using DTU and ONU to ring main unit, ring main unit failure is avoided or excluded.However, with urban economy development pair
The requirement of the primary equipments such as ring main unit is higher and higher, also further obvious in place of the deficiencies in the prior art, for example, ring main unit is usual
With multichannel outlet, and DTU and ONU can only be fixed on a certain position in ring main unit, then gone out each road of ring main unit using cable
When line is connected to DTU and ONU, cable routing is apart from long, and complicated, security is poor；And outlet it ought break down all the way
When, the monitoring to other all outlets can be influenced, causes whole ring main unit not work normally.Fig. 1 and Fig. 2 is the prior art

For module due to being stationarily connected in ring main unit group, internal cabling is chaotic；And the function module because its protective effect easily therefore
Barrier, needs to change the function module, but because its sets the defects of, often because of security consideration, it is necessary to which whole ring main unit group is broken
Electricity, What is more or even whole switching station's power-off, has seriously affected the power supply continuity and security of power distribution network；In addition, as schemed
Shown in 2, there are a large amount of space wastes on rear side of the function module, fail to make full use of.
Outdoor switching station can all influence the accurate of secondary device due to self structure reason, environmental problem, installation question etc.
Property, cause the malfunction of secondary device, add frequency of power cut, expand power supply interrupted district, increase maintenance workload.When need
When overhauling secondary device, anti-misoperation a sub-cell can generally be had a power failure or whole ring main unit has a power failure.When secondary device has event
Barrier, it is necessary to detect one by one, determines location of fault when carrying out largely arranging trouble hunting, then to producing the member of the failure
Device is replaced, and the work of substantial amounts of secondary connection and mode work carried out, can so expand region and the extension of power failure significantly
Power off time.And since producer and scheme of electric power are different, the component selected in various types of open air switching stations is often not
Together, size causes the component in outdoor switching station not have general and interchangeability it is even more impossible to unify, accordingly even when
During maintenance, the definite failure in scene, it is also possible to suitable member replacing can not be found in time, can not be restored electricity in a short time,
It cannot meet modern power reguirements.Damaging can occur in all ring main units in use and outdoor switching station, repair or
Replacement situation, and unit of operation of powering all can not possibly understand and know to the ring main unit of all producers and outdoor switching station,
Also can not to various types, different manufacturers, different scheme of electric power outdoor switching station and ring main unit in component have
Backup, so when ring main unit and outdoor opening and closing break down, it is impossible to find corresponding element replacement in time, causing cannot be high
Reliable continuous power supply.But advocated in today's society and improve distribution automation construction, highly reliable continuous power supply is also that distribution is automatic
That changes is basic.The length of power off time directly affects the direct economic loss of power supply unit, for electrified work as is continuously improved
Through society, reliable continuous power supply is even more important, and the loss of user is possible to the loss far beyond the electricity charge, reliable continuous power supply
By as the important measurement standard of power supply contract.Therefore standardization can only be improved, modularized equipment could be improved general and exchanged
Rate, but these producers and the existing very long history of equipment in use, are unable to reach high standardization and modularization for the moment.It is existing
Have and carried out some improvement in technology to outdoor switching station：As CN 202509989 discloses a kind of outdoor switching station, only for
