Description
Technical field
The utility model relates to a kind of electric equipment of environmental protection gaseous type Inflatable ring main unit.
Background technology
Because SF6 the meeting of global warming capital of a country is designated as greenhouse gases and limiting emission prevent in 1997, thus expect the birth not using the switch cubicle of SF6 gas.Environmental protection gas-insulated ring network cabinet easily to high voltage, high capacity expansion all occupies very large advantage technically, economically, causes market to filling SF
6the demand of Inflatable ring main unit successively decreasing year by year, replace SF
6the environment-friendly type ring main unit of Inflatable ring main unit will become the main flow in market, and replace SF gradually
6inflatable ring main unit.In general, can say that environment-friendly type gaseous type ring main unit is the best environment-friendly type switch cubicle not using SF6 gas completely.
Summary of the invention
The purpose of this utility model just there is provided a kind of indoor environmental protection gaseous type ring main unit, specifically a kind of Cubicle Gas-Insulated Switchgear for middle pressure grade, and for realizing above object, technical solution adopted in the utility model is:
Comprise housing, be located at the bus casing of case top, be located at the outlet casing tube of housing bottom, and the circuit breaker be located at respectively in housing, three-station, fixed contact and grounding contact, circuit breaker is fixed on the bottom of inwall on the right side of housing, fixed contact is fixed on the top of inwall on the right side of housing, grounding contact is fixed on the middle part of housing inner left wall, the quiet end at circuit breaker top is provided with bearing, the moved end, bottom of circuit breaker realizes being connected with the operating mechanism outside housing by insulated tension pole, three-station is fixed on the end face of bearing, movable touch knife on three-station can contact with grounding contact with fixed contact respectively, circuit breaker is connected with outlet casing tube by transition conductor, fixed contact is connected with bus casing by conductor.
The utility model adopts joins spring operating mechanism, adopts blade isolation earthing switch, can realize larger fracture; meet air insulation distance, be connected with cable by T-shaped cable termination, join annular straight-through current transformer; can increase and join voltage transformer, lightning arrester, realize protection and the metering of circuit.Therefore the utility model has the identical size of same SF6 gas cabinet, and be less than fraction solids insulation ring main unit, have real isolation fracture, overall structure novelty, good reliability, flexible arrangement, floor space are little, altitude module, the feature that production cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, it is completely isolated that metal enclosed housing 1 can realize with the external world, bus casing 7 is located at housing 1 top, lead collar, 11 bottoms being located at housing 1, circuit breaker 2 is fixed on the bottom of inwall on the right side of housing 1, fixed contact 6 is fixed on the top of inwall on the right side of housing 1, grounding contact 8 is fixed on the middle part of housing 1 inner left wall, and the quiet end at circuit breaker 2 top is provided with bearing 3, and the bearing 3 of epoxy casting plays fixed insulation effect.The moved end, bottom of circuit breaker 2 realizes being connected with the operating mechanism outside housing 1 by insulated tension pole 9, three-station 4 is fixed on the end face of bearing 3, three-station 4 has isolation, separating brake, grounding function, movable touch knife 5 on three-station 4 can contact with fixed contact 6 to realize isolating and close a floodgate, movable touch knife 5 also contacts with grounding contact 8 and is grounded function, circuit breaker 2 to be connected by transition conductor 10 equipment of realization line with outlet casing tube 11 connects, and fixed contact 6 to be connected by conductor the equipment of realization bus with bus casing 7 connects.
