Abstract
The invention discloses a main electrical connection of a double-bus disconnecting link section. The main electrical connection of the double-bus disconnecting link section at least comprises a double bus, outgoing breakers, a bus tie breaker, outgoing disconnecting switches, section disconnecting switches, bus tie disconnecting switches and bus facilities, wherein the double bus consists of two sections of buses; middles of the two sections of buses of the double bus are respectively sectioned by adopting two section disconnecting switches; the double bus is only provided with the bus tie breaker and the corresponding bus tie disconnecting switches; and both sides of the section of each section disconnecting switch on the double bus are respectively provided with a set of bus facilities. When electrical equipment normally runs by adopting gas insulated switchgear (GIS), the running mode of the electrical equipment is same as that of a double-bus connection. When a section of bus is maintained or an outgoing interval is extended, by operating the section disconnecting switches of the bus, one of sectioned buses can be ensured to normally run, and therefore, the power cut range is reduced, and the power supply reliability is improved.
Description
Technical field
The present invention relates to be a kind of isolation switch that adopts to the double-bus electrical main connecting wire that bus carries out segmentation, belong to double bus scheme technical field behind the GIS equipment.
Background technology
In recent years, GIS equipment (gas-insulating and fully-enclosed combined electrical apparatus) becomes one of mainstream configuration of China's electric equipment because compact conformation, the advantage such as occupation of land is little, operational reliability is high, maintenance workload is little have been widely applied in electric power system.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, have different operations, maintenance characteristics, thus the application of GIS equipment on the operation of electrical main connecting wire (mainly being 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 carried out withstand voltage test, the equipment such as high-tension cable, overhead wire, power transformer should be taked quarantine measures, and also being must have two fractures between withstand voltage test zone and the 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 be opened, 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 of using behind the 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 relatively poor, generally is used for the more situation of line feeder number.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned existence, provide a kind of energy by lower economic cost, reduce the power failure range in the above-mentioned situation, improve the electrical main connecting wire of the double-bus disconnecting link segmentation of power supply reliability.
The present invention is achieved through the following technical solutions: which comprises at least the double-bus that two sections buses consist of, wire-outgoing breaker, bus, the outlet isolating switch, sectionalizer, the mother isolating switch, bus equipment, adopt two sectionalizers to carry out segmentation in the middle of one section bus in the double-bus, another section bus also adopts two sectionalizers to carry out segmentation, and on described double-bus, only being provided with a bus and corresponding mother isolating switch, the sectionalizer segmentation both sides on the described double-bus respectively are furnished with a cover bus equipment.
The present invention adopts isolating switch that two sections buses are carried out segmentation, 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 adopts GIS equipment, when busbar overhaul and expansion spacing, can guarantee the normal operation of part circuit, reduce power failure range, improve power supply reliability.
Compare with typical double bus scheme, the invention has the beneficial effects as follows: solved and adopted in the situation of GIS equipment, when one section busbar overhaul and expansion spacing, the problem of two sections bus full cut-ofves.Compare with the two section wirings of double-bus, better economy of the present invention, second protection are relatively simple, are applicable to the less situation of line feeder number.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.Shown in Figure 1, the present invention includes the double-bus 1-1 that two sections buses consist of ~ 1-2, wire-outgoing breaker 2, bus 3, outlet isolating switch 4, sectionalizer 5-1 ~ 5-4, mother isolating switch 6, bus equipment 7 at least, it is characterized in that: double-bus 1-1 ~ 1-2 adopts respectively two sectionalizer 5-1 ~ 5-4 to carry out segmentation, and on described double-bus 1-1 ~ 1-2, only being provided with a bus 3 and corresponding mother isolating switch 6, the sectionalizer 5-1 on described double-bus 1-1 ~ 1-2 ~ 5-4 segmentation both sides respectively are furnished with a cover bus equipment 7.
Shown in the figure, also dispose as an illustration example of an outgoing line interval 8 to be extended on the described double-bus.
As a kind of improvement, the present invention does not adopt circuit breaker and adopts isolating switch that bus is carried out segmentation.During normal operation, sectionalizer 5-1 ~ 5-4 is closed, and operational mode is the same with double bus scheme; When maintenance bus 1-1, disconnect sectionalizer 5-1 and 5-3 on the respective bus bars; When maintenance bus 1-2, disconnect sectionalizer 5-2 and 5-4 on the respective bus bars, between maintenance zone and normal charging zone, form double-fracture, guarantee the normal operation of sectionalizer opposite side bus.When enlarging outgoing line interval 8, disconnect the sectionalizer 5-1 ~ 5-4 on two sections buses, when the bus section at expansion spacing place had a power failure, the bus of another segmentation kept normal operation.
At last, it should be noted that above what enumerate only is specific embodiments of the invention.Obviously, the invention is not restricted to above embodiment, a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive from content disclosed by the invention or associate all should be thought protection scope of the present invention.
