Description

Power distribution automation cabinet and outdoor switching station

Technical field

This utility model relates to electrical power distribution automatization system, more specifically, relate to a kind of power distribution automation cabinet, belongs to electrical equipment technical field of automation.

Background technology

Power system includes generating, transmission of electricity, power transformation, the several key link of distribution, and wherein distribution is the function that region be directly facing power consumer.In China, define for a long time " retransmit, light for, ineffective " situation, distribution network system seriously falls behind, and causes that residential electricity consumption line loss is high, voltage is low, it is unreliable to power, and becomes the power system bottleneck for electricity consumption.In early days during power grid construction, more pay attention to generating and transmission of electricity, and distribution and electricity consumption link are often little accounted of.Therefore, in recent years, country put into substantial contribution, through several city and countryside power grid modifications taken turns, has transformed substantial amounts of circuit, switch and transformator etc., has carried out distribution construction.Along with socioeconomic development, the process of electricity marketization deepens continuously, and user is to the requirement of reliability of electric power and quality also in continuous lifting, and urban distribution network radius of electricity supply is shorter and shorter, and power distribution network power distribution room is used widely.Power distribution network power distribution room is the spontaneous recovery of power distribution network and interactive key node, and " three is distant " monitoring of function singleness and the construction mode of feeder automation function are applied mechanically by power distribution room automatization, it is difficult to meet the demand for development of intelligent power distribution automation.And intelligent grid is the revolution again of power industry, it is the comprehensive solution of the reply whole world, whole mankind's energy, environment, weather, economy, sustainable development, represents the direction of following electrical network research and development.Power distribution network is electric energy application, user oriented window, is the important component part of intelligent grid, is also the intelligentized important breakthrough mouth of electrical network.

Power distribution automation refers to and utilizes hyundai electronics, communication technology, computer techno-stress technology to combine with power equipment; the work management of power distribution network monitoring under normal and accident conditions, protection, control, metering and power supply department is organically merged; improve power supply quality; more closely more responsible relation is set up with user; meet, with reasonable prices, the multiformity that user requires, make every effort to power supply economics best.At present, mostly it is based on the electrical power distribution automatization system of communication network, ca bin and background computer network, also the effect monitoring that power distribution network operation conditions and remote control change the method for operation can be played when power distribution network is properly functioning, can discover in time during fault, but mostly lack automatic control function.Even if minority system has automatic control function, also because system is excessively complicated, redundancy so that with high costs, be not suitable for popularization and application.

Before reform and opening-up, most cities is but without forming large stretch of special compact district of load, therefore user's power supply is directly or indirectly deliver to user transformers by the 10KV circuit from transformer station mostly, distribution system is mainly to set dry fit radiant type, and system connects simple.But, over nearly 20 years, national economy there occurs change at full speed, and city tends to densification, urbanization, and urban distribution network power load soars, and defines load intensive district, and load density is from original hundreds of kW/km²Rise to tens thousand of kW/km², original power supply mode exposes many weakness significantly: circuit is long, and line loss is big, quality of voltage is poor, troubleshooting situation is complicated, and line facility operation maintenance management workload is big, and Add User dilatation difficulty, due to urban planning requirement, 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 proposes a kind of new power supply mode in recent years and pass through switching station to the difference of customer power supply, these switching stations and transformer station only without main transformer and chopper.On distribution network wiring construction, development trend is to adopt looped network form to power, and ring network power supply pattern can improve the reliability of power supply, and user can obtain power supply, the power failure area of minimizing accident from switching station ring-main unit end.Ring network structure has monocycle, multi-ring dividing, and also has the difference of open loop, closed loop.According to use function difference, monocycle, open loop operation distribution network systems one second part can be divided into 5 modules；1) transformer station's wire-outgoing breaker；2) loop grid；3) loop-network switch cabinet；4) user 10KV power distribution equipment；5) user transformers.Various combination according to loop-network switch cabinet, user's 10KV power distribution equipment and user transformers, looped network switchyard, customer substation and three kinds of different modes of looped network customer substation can be formed, in these patterns, as the main equipment ring main unit of ring network power supply, then increasingly it is subject to the attention of power supply department and user.

Switching station is the electric equipment that one group of high-tension switch gear or ring main unit were contained in metal or non-metallic insulation cabinet or made assembled compartment ring network power supplying units, it is as the basic ingredient of urban distribution network, and the safety of switching station is the important leverage of distribution network feeder safety.In recent years, in urban distribution network, the accident of power supply occurred due to switching station fault is of common occurrence.Common switching station fault includes switch malfunction, relay fail, external force is destroyed, switching gas leaks, end generates heat blast etc..The effective ways of this problem of existing solution are to install distribution automation remote terminal DTU, corresponding communicating terminal ONU in switching station and be arranged on the Microcomputer Protection at ring main unit group top and control module realization.Adopt distributed frame and centralized configuration to be arranged in switching station these automation function modules (Microcomputer Protection and control module) in prior art, ring main unit is interior or operating mechanism is indoor.Installation for the automatic function module of distributed frame is divided into two ways to install: one is to arrange inside ring main unit by this kind of automation function module, but there is inside ring main unit the high pressure equipment of 10000V, the arrangement space difficulty of DTU and ONU, even if can install, it is also difficult to ensure completely stable operation；Another kind of be this kind of automation function module is attached to that ring main unit is outer, in switching station, and arbitrarily putting of this kind of automation function module, cause operational outfit to put messy, bring certain impact to maintenance work.It is this kind of functional module is independently concentrated in a protection device cabinet for centralized configuration; such as existing a kind of cabinet type DTU closed equipment; main control chip and the interface being connected with ring main unit Zhong Ge road outlet it is provided with in the cabinet body of DTU; by each road outlet of ring main unit is respectively connecting to DTU and ONU; to utilize DTU and ONU that ring main unit is monitored, it is to avoid or get rid of ring main unit fault.But, along with urban economy development is more and more higher to the requirement of the primary equipments such as ring main unit, the deficiencies in the prior art part is also further obvious, ring main unit is generally of multichannel outlet, and DTU and ONU can only be fixed in ring main unit a certain position, then when utilizing cable that each road outlet of ring main unit is connected to DTU and ONU, cable routing is apart from long, and to pass through in other control chamber, structure is complicated, and safety is poor；When Qie Dang mono-tunnel outlet is broken down, the monitoring to other all outlets can be affected, cause that whole ring main unit cannot normal operation.Fig. 1 and Fig. 2 is front view and the sectional view of outdoor switching station of the prior art, as depicted in figs. 1 and 2: being placed in the Microcomputer Protection on ring main unit group top and control module owing to being stationarily connected in ring main unit group, internal cabling is chaotic；And this functional module is because of its protective effect very easily fault, this functional module need to be changed, but because of the defect of its setting; often because of security consideration; needing to have a power failure whole ring main unit group, What is more or even whole switching station has a power failure, and has had a strong impact on power supply continuity and the safety of power distribution network；Additionally, as in figure 2 it is shown, the rear side of this functional module has a large amount of space waste, fail to make full use of.

Outdoor switching station all can affect the accuracy of secondary device due to self structure reason, environmental problem, installation question etc., causes the misoperation of secondary device, adds frequency of power cut, expand power supply interrupted district, increases maintenance workload.When needs overhaul secondary device, anti-misoperation generally a sub-cell can be had a power failure or whole switching station has a power failure.When secondary device has fault to carry out substantial amounts of row's trouble shooting, need to detect one by one, it is determined that location of fault, then the components and parts producing this fault are changed, and the substantial amounts of secondary connection work carried out and mode work, so can significantly expand the region of power failure and extend power off time.In addition, owing to producer and scheme of electric power are different, the components and parts that power distribution cabinet in various types of outdoor switching stations is selected are often different, size more cannot be unified, and causes that in outdoor switching station, the components and parts of power distribution cabinet do not have general and interchangeability, accordingly even when when maintenance, fault is determined at scene, it is likely to and cannot find suitable member replacing in time, it is impossible to restore electricity at short notice, it is impossible to meet modern power reguirements.Damaging, keeping in repair or replacing situation can occur in ring main unit and power distribution cabinet in all uses, and the ring main unit of all producers and power distribution cabinet cannot all be understood and know by unit of operation of powering, also the components and parts in various dissimilar, different manufacturers, the power distribution cabinet of different scheme of electric power and ring main unit cannot there be is backup；So when ring main unit and outdoor opening and closing break down, it is difficult to finding corresponding element replacement in time, causing can not highly reliable continuous power supply.But advocating at society and improve distribution automation construction, the reliable power supply continuously of high stability is also the basic of distribution automation.The length of power off time directly affects the economic loss of power supply unit, electrified when through society for improving constantly, reliable power supply continuously is even more important, and the actual loss of user is likely far beyond the loss of the electricity charge, and reliable power supply continuously will become the important criterion of power supply contract.Therefore can only improve standardization, modularized equipment could improve general and interchangeability, but the producer producing or developing switching station or ring main unit is numerous, the history that in especially all kinds of uses, equipment is existing very long, is unable to reach high standardization and modularized production design for the moment.Outdoor switching station or even power distribution cabinet are carried out some by prior art improve: as CN202509989 discloses a kind of outdoor switching station, carried out simple structure only for its door and improved, original bellow framed door is changed into left and right sliding door；As Chinese patent CN103715616 discloses a kind of ring main unit, the global design of ring main unit being simplified to simplify back panel wiring and reduces installation workload, the Microcomputer Protection not being opposite to ring main unit top and the internal structure controlling module improve；As Chinese patent CN203367797 discloses a kind of intelligent power distribution automatization terminal case, automatization terminal case is divided into a secondary chamber and secondary chamber's up-down structure, is still difficult to confirm the fault of automatization terminal case to cause maintenance difficult；As Chinese patent CN202997354 discloses a kind of distribution automation ring main unit, this ring main unit includes some ring main units, DTU cabinet and communication counter, but the structure in DTU cabinet and communication counter cabinet is not improved；As Chinese patent CN103579946 discloses a kind of distribution automation integration ring main unit, integrate distribution automation intelligent terminal and switchgear, but the structure of automatic intelligent terminal is not improved.
