Description
Technical field
The utility model relates to low-voltage distribution apparatus, specifically is that a kind of transformer station AC low voltage power switch board is concentrated screen.
Background technology
Transformer station is the important component part that is related to substation safety stable operation with alternating-current system, stands with the safe operation of the steady operation of the AC power handoff relation when unusual to equipment.Existing station is controlled by each assembly electronic box respectively with AC load.Existing station has with the main load of AC system:
1, main transfer wind cooling system (220kV and more than): 400V I, II section go out on wiretap is combined, and are cut to corresponding bus by power transfer device in the main transformer cooler control cabinet;
2, breaker mechanism energy storage and plug-in strip operating power: from 400V I, II Duan Shoudian, adopt the loop service mode, must not cyclization move under the normal condition;
3, master control building switchboard: from 400V I, II Duan Shoudian, under the normal condition on the switchboard two road service entrance switchs must not close simultaneously.Main charger, inverter, air-conditioning, the illumination even load of supplying;
4, traffic load outdoor lighting;
5, maintenance power supply box;
6, fire pump, rainwater pump;
7, GIS chamber ventilated system dynamic power supply;
8, socket etc.
In the at present complete indoor 110kV transformer station, each station links to each other with AC panel with outlet through distribution box with AC load.Distribution box quantity reaches 8 (7 of A.C. distribution boxs, emergency lighting case 1 faces), and simultaneously outlet loop number average all is installed on the wall of field apparatus chamber or on the wall of master-control room between 6-8 returns.This arrangement mode has following deficiency:
To water power perforate, cloth pipeline, the difficulty of construction of wiring is bigger when 1, installing distribution box.When on control room or canyon metope, installing distribution box; Need to dig metope, water power perforate, arrange pipeline; Not only workload is big but also can produce decoration garbage and dust pollution, has also increased the operating efficiency that workload influences installation personnel and workmen again.Distribution box go out line loop generally between 6-8 returns, arrange the loop outlet at metope, the position of its cabling also need be designed and considered, after construction finishes, need repair and whitewash the metope of digging.Not only time-consuming, effort, and increased workload and estimated cost.
2, outlet is buried within the walls, and the distribution box space is limited, is unfavorable for maintenance and safeguards.The distribution box space of installing on the metope of control room is limited, overhauls with wiring and when safeguarding, need distribution box be opened when the staff need open sky, in case of necessity also need be with carrying out repair work after its dismounting down.When repairing is safeguarded, because the space is limited, can only find inlet wire termination and the empty situation of opening part, can't check for the inlet wire of imbedding the metope part.3, distribution box is loaded on metope, need stick the panel tab, otherwise is unfavorable for Classification Management.
4, traditional AC low voltage power switch board case is dispersed on the metope of master-control room and field apparatus chamber or corridor.If break down in the low-voltage alternating-current loop, a certain road in the station, its low-voltage alternating-current sky is opened tripping.When the operations staff searches fault loop, need to make an inspection tour the metope of each canyon comprehensively, find out the sky of fault disconnection and open.If the transformer station place is bigger, low-tension distribution box distributes when disperseing, and searches more loaded down with trivial detailsly, takes time and effort.
5, some distribution box is installed in the open air, though installed protective equipment such as rain cover additional, owing to receive the invasion and attack of wind and rain for a long time out of doors, can cause unavoidably and make moist or the decline of insulating, and causes fault.
Summary of the invention
The utility model technical problem to be solved is, provides a kind of simple in structure, construction and transformer station's AC low voltage power switch board easy to maintenance, as to be convenient to centralized monitor to concentrate screen.
Transformer station's AC low voltage power switch board of the utility model concentrates screen to include a cabinet, in cabinet, is divided into a plurality of interlayers from top to bottom through dividing plate, and many groups AC power of each AC load in the may command transformer station is set respectively in each interlayer.
Said cabinet top is provided with ventilating opening, so that heat radiation, the place is provided with Air Filter at ventilating opening, to avoid use and the life-span that dust gets into influences mains switch.
The advantage applies of the utility model exists:
1, transformer station is gathered a unified low-voltage distribution with all kinds of low-voltage alternating-current distribution boxs and concentrate on the screen, not only guaranteed the repertoire of original distribution box, and make indoor layout in order unified, the metope neat and tidy has guaranteed aesthetic property.
2, easy construction does not exist a large amount of perforates, stringing problem, need not dig metope, has guaranteed the integrality of metope.Time saving and energy saving, reduced workload and labour cost.
3, the concentrated low-voltage distribution that is installed in of distribution box is concentrated on the screen, can conveniently be repaired maintenance.Open the screen rear cabinet door, can start working, whenever all clearly behind screen, show, make things convenient for the cabling wiring, improved repair and maintenance efficient back into outlet.
4, the concentrated low-voltage distribution that is installed in of distribution box is concentrated on the screen, each AC distribution source layered arrangement, the function division management, clear in structure, easy to use.If after concentrating screen, install relay additional, make warning device, upload to the remote monitoring backstage through the communication screen again, can form remote monitoring to transformer station's low-voltage alternating-current electricity consumption.
5, break down in the low-voltage distribution loop, just opens through the sky of trouble-shooting tripping at panel and can find fault loop fast, simplified the tour search procedure greatly, improved efficient.
6, the concentrated low-voltage distribution that is installed in of distribution box is concentrated on the screen, can be avoided causing erosion, effectively reduce failure rate, guaranteed safety distributed board outdoor owing to expose to wind and rain for a long time.
7, because present 220kV and following transformer station have all realized unattended, operation and maintainer need comprehensively administer and maintain each transformer station of being administered, and workload is big.The concentrated 400V low-voltage distribution that is installed in of distribution box is concentrated on the screen, thereby ignored the similarities and differences of conventional low distribution box, form and seek unity of standard, convenient operation and maintenance in the distribution of the house of each transformer station.
