Description
Technical field
The utility model belongs to protects power supply technique field, relates in particular to a kind of power supply capacitor box coupling assembling of protecting.
Background technology
Along with social change and progress, high level and high-rise building are more and more, due to accident cause tens even tens skyscrapers have a power failure, for power supply enterprise, complain pressure quite large, for high level and high-rise building provide emergency power supply comparatively general now; In addition power supply enterprise bears increasing social responsibility, as: college entrance examination, in examine, that power supply task is protected in place that the personnel such as party, political affairs, momentous conference of Jun Deng department, big assembly, megastore, large hotel are comparatively intensive etc. is more and more; And disaster accident scene needs quick emergency service.This just requires us not depend alone to improve peopleware, establishment emergency preplan realizes, and more will start with from equipment, simplifies the operation, improves equipment and technology content, ensures that personal security starts with.
In low pressure group cabinet in transformer station's low-pressure chamber of original design, do not give the special purpose interface that stays emergency power generation vehicle, in the time meeting guarantor's power supply task or accident, be difficult to effectively carry out emergency service.The following two schemes of the general employing of Emergency electricity:
1, in low pressure feeds out cabinet, have and give in the situation of staying switch, general employing is connected on to give to be stayed on switch, stays the anti-low pressure busbar of delivering to of switch by giving, and is transformer station's low-voltage load power supply all or in part.The drawback of this kind of scheme is, gives the air cock of leaving a blank with low capacities such as 125A, 200A, 400A, is with transformer station's low-voltage load electric current all or in part.Easily cause the phenomenon of high load with small power, in the time that load current is larger, very easily causes and give the air cock overcurrent protection tripping operation of leaving a blank, cause and protect power supply interruption or protect and power unsuccessfully.
2, in low pressure feeds out cabinet, give in the absence of staying switch, general employing disassembled busbar or switch terminal, and generator car cable is connected in parallel on busbar or terminal, delivering to busbar or directly pass through low pressure busbar by air switch is counter, is transformer station's low-voltage load power supply all or in part.The drawback of this kind of scheme is, equally also has the phenomenon of high load with small power, in the time that load current is larger, very easily causes and gives the air cock overcurrent protection tripping operation of leaving a blank, and causes and protects power supply interruption or protect and power unsuccessfully.This kind of scheme, in the time of wiring and while removing wiring, need to be cut off all or part of low-voltage load in addition.For some important places as: the responsible consumers such as large hotel, meeting, party, political affairs, Jun Deng department, market, examination hall, high level and high-rise building are higher or other factors to power reguirements, wiring can not have a power failure, cause generator car to be connected with low-voltage equipment, cause to protect and power unsuccessfully or cannot carry out.
Above two schemes, all relates to safety problem, more or less exists contiguous charged position to carry out wiring operation.Due to the limited space in low-voltage cabinet, in the time carrying out this type of wiring operation, operating personnel's personal safety is brought to very large threat, very easily cause single-phase earthing or phase fault, people is for causing operating equipment fault stop transport or cause operating personnel's personal injury.
Above two schemes, processing very blunt of all seeming when accident.Manually disassemble, screwing screw is time-consuming, bothersome dangerous again, under some hazardous condition as: scene of fire, flue gas are large, lower indoor, the above two kinds of programmes of work that cannot stop for a long time of visibility all cannot be realized emergency service.
