Abstract
The utility model relates to an open-type outdoor high-voltage combined electric appliance comprising two groups of isolating switches, a mutual inductor, a circuit breaker, a an integrated control box and a base, wherein the two groups of isolating switches are respectively arranged at both ends above the base and connected with the circuit breaker through the mutual inductor, a vacuum circuit breaker serves as the circuit breaker, and a mechanism case for the vacuum circuit breaker, a mechanism case for the isolating switches and the bus-control case are respectively arranged under the base. The mutual inductor and the vacuum circuit breaker are perpendicular to and fixedly connected with each other into a whole. The open-type outdoor high-voltage combined electric appliance have the characteristics of compact structure, small floor occupation, strong breaking capability, high reliability, no exhaust of SF6 gas, and the like.
Description
Technical field
The utility model relates to the technical field of electrical equipment in a kind of transformer station, specifically a kind of open type outdoor high-voltage combined electrical apparatus.
Background technology
Along with Chinese economic development, the construction scale in electricity needs and electrical network power station also enlarges day by day, and is therefore also increasing with the contradiction of protection to the demand of resource, and particularly in recent years, people realize the protection of environment and risen to strategic position.Traditional combined electrical apparatus mainly contains two types at present: be called for short the Cubicle Gas-Insulated Switchgear of GIS and the air insulation open type switchgear of abbreviation AIS.The GIS compact conformation, floor space is little, reliability is high, the operation maintenance workload is little but cost an arm and a leg, overhaul difficulty, the environmental pollution degree is big, particularly its SF6 gas that adopts is the strongest a kind of of greenhouse effect, and it is bigger to environmental hazard in a power equipment manufacturing factor; The AIS price is low, maintenance is convenient, flexible but floor space is big, and connecting-disconnecting function is poor, poor reliability.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, and floor space is little, and connecting-disconnecting function is strong, reliability height, the open type outdoor high-voltage combined electrical apparatus of no SF6 gaseous emission.
For achieving the above object, the technical solution adopted in the utility model is: a kind of open type outdoor high-voltage combined electrical apparatus, comprise isolating switch, instrument transformer, circuit breaker, central console and base, it is characterized in that: described isolating switch has two groups, be separately positioned on the two ends, top of base, two groups of isolating switches are connected with circuit breaker by instrument transformer, described circuit breaker is a vacuum circuit-breaker, described instrument transformer and vacuum circuit-breaker are vertical configuration and fixedly connected and be integral, and the mechanism case of vacuum circuit-breaker, the mechanism case of isolating switch and central console all are arranged on the below of base.
The utility model design has two groups of isolating switches, be separately positioned on the two ends, top of base, be connected with circuit breaker by instrument transformer between two groups of isolating switches, mechanism case, the mechanism case of isolating switch and the below that central console all is arranged on base of while vacuum circuit-breaker, the arrangement compactness of this combined electrical apparatus, floor space is little, stable and reliable operation; Circuit breaker of the present utility model adopts vacuum circuit-breaker, electric strength height not only, and connecting-disconnecting function is strong, and stops the discharging of strong greenhouse gases SF6 common in the mesohigh electric equipment, avoids the pollution to environment.

Fig. 1 is a structural representation of the present utility model
Embodiment
Now in conjunction with the accompanying drawings utility model is further described, the utility model mainly comprises isolating switch 1, instrument transformer 2, circuit breaker 3, central console 5 and base 6, described isolating switch 1 has two groups, be separately positioned on the two ends, top of base 6, two groups of isolating switches 1 are connected with circuit breaker 3 by instrument transformer 2, described circuit breaker 3 is a vacuum circuit-breaker 3, and the mechanism case 7 of vacuum circuit-breaker 3, the mechanism case 4 of isolating switch 1 and central console 5 all are arranged on the below of base 6.Instrument transformer 2 of the present utility model and vacuum circuit-breaker 3 are vertical configuration and fixedly connected and be integral, instrument transformer 2 vertically is arranged on the base 6 by compound porcelain sleeve, vacuum circuit-breaker 3 is a horizontally set then, and the moving contact in this enforcement in two groups of isolating switches 1 is articulated and connected respectively in the top of instrument transformer 2 and the outer end of vacuum circuit-breaker 3.
This arrangement compactness of the utility model, floor space is little, stable and reliable operation.Circuit breaker of the present utility model 3 adopts vacuum circuit-breakers 3, vacuum circuit-breaker 3 be with vacuum as insulation and arc-extinguishing medium, thereby compare traditional oil circuit breaker and SF6 circuit breaker, its electric strength is higher, connecting-disconnecting function is stronger.Simultaneously because this special insulation arc-extinguishing medium of vacuum, make the danger of vacuum circuit-breaker 3 no fire and blast, more there is not the discharging of strong greenhouse gas such as SF6.The mechanism case 4 of isolating switch 1 of the present utility model can be according to user and the different mechanism case 4 of engine request preparation, and what the mechanism case 4 of present embodiment adopted is the CT19 spring operating mechanism.
This shows that the utlity model has compact conformation, floor space is little, connecting-disconnecting function is strong, reliability height, the characteristics such as no SF6 gas discharging.
