Abstract
The invention discloses a split-type gas insulated switchgear. A bus chamber is internally provided with a plug-in bus and the plug-in bus is combined with an internal taper in a gas box in a plug-in way; the internal taper is connected with a static contactor at a line feeding end of an isolation and grounding three-position switch; the static contactor at the line feeding end of the isolation and grounding three-position switch is connected with one end of an insulation screw rod and the other end of the insulation screw rod is connected with a static contact at a grounded end of the isolation and grounding three-position switch; the insulation screw rod is connected with a screw rod transmission mechanism and a movable contactor of the isolation and grounding three-position switch is matched with the insulation screw rod through internal screw threads; the movable contactor of the isolation and grounding three-position switch is connected with a line discharging end of the movable contactor of the isolation and grounding three-position switch; and a vacuum circuit breaker is arranged inside the gas box. The split-type gas insulated switchgear provided by the invention is rational in structure, convenient for overhauling and good in product performance.
Description
Technical field
The present invention relates to a kind of gas-insulated switchgear.
Background technology
There is problems such as safeguarding inconvenience in existing gas-insulated switch, and service behaviour is also undesirable.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, maintenance is convenient, the split type gas-insulated switchgear of good product performance.
Technical solution of the present invention is:
A kind of split type gas-insulated switchgear, comprise bus-bar room, gas tank, the cable vault, spring operating mechanism, vacuum circuit-breaker, it is characterized in that: dress plug-in bus in the bus-bar room, the inner cone plugging formula of plug-in bus in gas tank is combined, inner cone and isolation, the inlet wire side fixed contact of ground connection three-station connects, isolation, the inlet wire side fixed contact of ground connection three-station is connected with an end of insulation screw mandrel, the other end and the isolation of insulation screw mandrel, the earth terminal fixed contact of ground connection three-station connects, the insulation screw mandrel is connected with lead screw transmission mechanism, isolation, the moving contact of ground connection three-station cooperates isolation by internal thread with the insulation screw mandrel, the moving contact of ground connection three-station and isolation, the leading-out terminal of ground connection three-station connects; Vacuum circuit-breaker is arranged in the gas tank.
Described plug-in bus comprises copper busbar, copper busbar is coated with silicone rubber insulation layer, one end of copper busbar is the outside busbar shiplap joint face that is flat, the other end of copper busbar be with gas-filling cabinet in the bond end of inner cone, the second silastic-layer is set outside the silicone rubber insulation layer of this bond end, and the end of the second silastic-layer is tapered, and the middle part of the second rubber layer has arranged the semi-conductive layer of earth shield effect.The bond end of the inner cone in copper busbar and the gas-filling cabinet adopts double-screw bolt and inner cone and connects.
The present invention is rational in infrastructure, when the switchgear fault must be changed, need not to remove bus, removal cable, need not the equipment of mobile side direction, can remove easily the insertion switch cubicle from the front, and maintenance is changed very convenient; Circuit breaker and isolating switch are installed in the gas tank, as an integral module insert-seal gas tank, and the debugging in the production process and safeguard very conveniently, properties of product are stable; Copper busbar one end is that its external shape is consistent with the internal structure of corresponding inner cone with corresponding inner cone overlap so that and connect rear formation full-shield, hermetically sealed, all insulation, compact conformation; The present invention is easy for installation, and maintenance workload is little, neat appearance.
