Description
Technical field
The invention belongs to guarantor's power supply technique field, more particularly, to a kind of guarantor's power supply capacitor cabinet coupling assembly.
Background technology
With social change and progress, executive information systems get more and more, because accident causes more than ten even
Tens skyscrapers have a power failure, and complain pressure quite big for power supply enterprise, provide emergent for executive information systems
Power supply is now more universal；In addition power supply enterprise undertakes increasing social responsibility, such as: college entrance examination, in examine, party, political affairs,
More intensive place of the personnel such as momentous conference of Jun Deng department, big assembly, megastore, large hotel etc. is protected power supply task and is got over
Come more；And disaster accident scene needs quick emergency service.This requires that we can not depend raising peopleware, establishment alone
Emergency preplan, to realize, more will be started with from equipment, simplify operation, improve equipment and technology content, ensure that personal security is started with.
In the low pressure group cabinet of transformer station's low pressure interior of original design, do not give the special purpose interface staying emergency power generation vehicle,
Meet and be difficult to when guarantor's power supply task or accident effectively carry out emergency service.Emergency electricity typically adopts following two
Scheme:
1st, feed out in cabinet in low pressure, give in the case of staying switch, typically stayed on switch using being connected on to give, stayed out by giving
Pass is counter to deliver to low-voltage busbar, powers for transformer station's low-voltage load all or in part.The drawbacks of this kind of scheme, is, with 125a,
The low capacities such as 200a, 400a give air cock of leaving a blank, band transformer station's low-voltage load electric current all or in part.Easily cause pony to widen
The phenomenon of car, when load current is larger, easily cause to give leave a blank air cock overcurrent protection tripping operation, cause protect power supply interruption or
Protect and power unsuccessfully.
2nd, feed out in cabinet in low pressure, do not give in the case of staying switch, typically using disassembling busbar or switch terminal, will
Generator car cable is connected in parallel on busbar or terminal, delivers to busbar or directly passes through low-voltage busbar by air switch is counter, for whole
Or part transformer station low-voltage load powers.The drawbacks of this kind of scheme, is, equally there is also the phenomenon of high load with small power, works as load
When electric current is larger, easily cause to give air cock overcurrent protection tripping operation of leaving a blank, cause to protect power supply interruption or guarantor powers unsuccessfully.In addition
This kind of scheme, in wiring and when removing wiring, needs to cut off all or part of low-voltage load.For some important places such as: big
The responsible consumers such as type hotel, meeting, party, political affairs, Jun Deng department, market, examination hall, executive information systems are higher to power reguirements
Or other factors, it is impossible to power failure wiring, lead to generator car cannot be connected with low-voltage equipment, cause to protect and power unsuccessfully or cannot enter
OK.
Both the above scheme, all refers to safety problem, more or less there is neighbouring powered position and carries out wiring operation.By
Limited space in low-voltage cabinet, when carrying out such wiring operation, the personal safety to operating personnel brings very big threat,
Easily cause single-phase earthing or phase fault, artificially cause operating equipment fault to stop transport or cause operating personnel
Personal injury.
Both the above scheme, all seems very blunt when processing accident.Manually disassemble, screwing screw is expense
When, bothersome and dangerous, under some hazardous condition such as: scene of fire, flue gas is larger, visibility is relatively low cannot stop for a long time
The interior stayed, both the above programme of work all cannot realize emergency service.
