Abstract
Provided is a duplicate-busbar disconnecting switch segmented electric main connection wire. The electric main connection wire at least comprises a duplicate-busbar composed of two segments of busbars, a wire-outgoing circuit breaker, a bus tie circuit breaker, wire-outgoing isolation switches, segmentation isolation switches, bus tie isolation switches and busbar devices. The electric main connection wire is characterized in that the middle portions of the two segments of the busbars of the duplicate-busbar are respectively segmented by using two segmentation isolation switches, and the duplicate-busbar is only provided with the one bus tie circuit breaker and the corresponding bus tie isolation switches, and the two segmentation sides of segmentation isolation switches on the duplicate-busbar are respectively provided with a busbar device. When an electrical apparatus with a GIS device works normally, the running mode is the same as that of the duplicate-busbar connection wire; when a segment of a busbar is inspected or a wire-outgoing interval is expanded, by operating the busbar segmentation isolation switches, one segment busbar can be ensured to work normally, the power failure scope is reduced, and the power supply reliability is improved.
Description
Technical field
The utility model relates to a kind of isolation switch that adopts and bus is carried out to the double-bus electrical main connecting wire of segmentation, belong to double bus scheme technical field after GIS equipment.
Background technology
In recent years, GIS equipment (gas-insulating and fully-enclosed combined electrical apparatus) due to compact conformation, take up an area the advantages such as little, that operational reliability is high, maintenance workload is little, in electric power system, widely applied, become one of mainstream configuration of China's electric equipment.At present, we are based on conventional AIS equipment for application, the assay of electrical main connecting wire, and GIS equipment is compared with the AIS conventional equipment, there are different operations, maintenance characteristics, thus the application of GIS equipment on the operation of electrical main connecting wire (being mainly the main electrical scheme of double bus scheme class), safeguard and produced certain impact.
According to the inspection travel rules regulation of GIS equipment, when GIS equipment carries out withstand voltage test, the equipment such as high-tension cable, overhead wire, power transformer should be taked quarantine measures, and being also must have two fractures between withstand voltage test zone and normal charging zone.Therefore, for double bus scheme, when carrying out interval enlarging or busbar overhaul need to do withstand voltage test the time, the circuit breaker of line and isolating switch all need to open, thereby have caused two sections bus full cut-ofves.For double bus scheme, a very large advantage is exactly when one section busbar overhaul and expansion spacing, can guarantee the normal power supply of other one section bus; And the operation of GIS equipment self, maintenance characteristics have caused the double bus scheme after application GIS equipment will lose this advantage.If adopt the two section wirings of double-bus; although in the time of can guaranteeing the busbar overhaul of segmentation one side; the bus of segmentation opposite side normally moves; but the two section wirings of double-bus need increase bus section breaker and mother, bus equipment newly; increase of investment is larger; second protection is also more complicated, and economy is poor, is generally used for the more situation of line feeder number.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provides a kind of energy by lower economic cost, reduces the power failure range in above-mentioned situation, improves the electrical main connecting wire of the double-bus disconnecting link segmentation of power supply reliability.
The utility model is achieved by the following technical solution: which comprises at least the double-bus that two sections buses form, wire-outgoing breaker, bus, the outlet isolating switch, sectionalizer, the mother isolating switch, bus equipment, in the middle of one section bus in double-bus, adopt two sectionalizers to carry out segmentation, another section bus also adopts two sectionalizers to carry out segmentation, and only be provided with a bus and corresponding mother isolating switch on described double-bus, sectionalizer segmentation both sides on described double-bus respectively are furnished with a set of bus equipment.
The utility model adopts isolating switch to carry out segmentation to two sections buses, need not increase bus section breaker and mother, bus equipment newly, realized the advantage of the two section wirings of double-bus with less investment, in the situation that adopt GIS equipment, when busbar overhaul and expansion spacing, can guarantee the normal operation of part circuit, reduce power failure range, improve power supply reliability.
With typical double bus scheme, compare, the beneficial effects of the utility model are: solved and adopted in the situation of GIS equipment, and when one section busbar overhaul and expansion spacing, the problem of two sections bus full cut-ofves.With the two section wirings of double-bus, compare, the utility model better economy, second protection is relatively simple, is applicable to the less situation of line feeder number.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.Shown in Fig. 1, the utility model at least includes the double-bus 1-1 that two sections buses form ~ 1-2, wire-outgoing breaker 2, bus 3, outlet isolating switch 4, sectionalizer 5-1 ~ 5-4, mother isolating switch 6, bus equipment 7, it is characterized in that: double-bus 1-1 ~ 1-2 adopts respectively two sectionalizer 5-1 ~ 5-4 to carry out segmentation, and only be provided with a bus 3 and corresponding mother isolating switch 6 on described double-bus 1-1 ~ 1-2, sectionalizer 5-1 on described double-bus 1-1 ~ 1-2 ~ 5-4 segmentation both sides respectively are furnished with a set of bus equipment 7.
Shown in figure, also dispose an outgoing line interval 8 to be extended on described double-bus as illustrated example.
As a kind of improvement, the utility model does not adopt circuit breaker and adopts isolating switch to carry out segmentation to bus.During normal operation, sectionalizer 5-1 ~ 5-4 closure, operational mode is the same with double bus scheme; When maintenance bus 1-1, disconnect sectionalizer 5-1 and 5-3 on respective bus bars; When maintenance bus 1-2, disconnect sectionalizer 5-2 and 5-4 on respective bus bars, form double-fracture between maintenance zone and normal charging zone, guarantee the normal operation of sectionalizer opposite side bus.When enlarging outgoing line interval 8, disconnect two sections sectionalizer 5-1 ~ 5-4 on bus, when the bus section at expansion spacing place has a power failure, the bus of another segmentation keeps normal operation.
Finally, it should be noted that above what enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection range of the present utility model.
