Abstract
The utility model relates to the high voltage electrical field, and more specifically relates to a breaker-isolating switch combination device. A breaker mechanism and an isolating switch mechanism are connected to be a whole body via screws, and are fixed on one side of a sealing plate. A solid sealing pole column is fixed on the other side of the sealing plate. The lower wire leading-out end of the solid sealing pole column is connected with an isolation blade, and the upper wire leading-out end of the solid sealing pole column is used for fixing the closing cutter head of an isolating switch via an insulator. According to the utility model, the breaker and the isolating switch are combined to the whole body, such that a direct connecting portion between the central isolating switch and the breaker is minimized, the volume of a cabinet body is reduced, the cost is lowered, and a miniaturization advantage is exhibited.
Description
Technical field
The utility model relates to the high-voltage electrical apparatus field, the composite set of a kind of circuit breaker-isolating switch of more specifically saying so.
Background technology
At present, circuit breaker and isolating switch are split type, and circuit breaker and isolating switch respectively are in one independently in the gas tank; Institute takes up space big, can not satisfy the demand of existing high-tension apparatus miniaturization, and because circuit breaker is in different gas tanks with isolating switch; Between need the many places copper bars to connect; And need the many places sealing, and having increased the quantity that connects materials such as copper bar greatly, cost is higher.
The utility model content
The technical problem that the utility model will solve has been to provide a kind of composite set of circuit breaker-isolating switch; Circuit breaker and isolating switch are integral type; Reduced the direct coupling part of intermediate isolating switch and circuit breaker; Dwindle the cabinet volume greatly, reduced cost, and had the advantage of miniaturization.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of composite set of circuit breaker-isolating switch; Have breaker mechanism, isolating switch mechanism, pole; Described breaker mechanism and isolating switch mechanism are connected to integral type through screw, and are fixed on sealing plate one side, and pole is fixed on the sealing plate opposite side; Be connected with the isolation blade on the lower wire end of pole, the last leading-out terminal of pole passes through fixedly isolating switch combined floodgate cutter head of insulator.
Pole inside is stretched out insulated tension pole and is passed sealing plate and link to each other with the opposite side breaker mechanism, and the final drive shaft of isolating switch mechanism is connected with the isolation blade.
When the isolating switch mechanism action, impel final drive shaft to rotate, isolate blade rotation thereby drive, realize that isolating switch switches at combined floodgate, isolation, ground connection three stations.
When the isolation blade forwards closing position to, just realized that electric current through leading-out terminal on the pole, gets into pole; Pass through to isolate blade from lower wire end; To the combined floodgate cutter head, flow out through the copper bar that connects the combined floodgate cutter head at last, realized the double function of isolating switch and circuit breaker.
The beneficial effect of the utility model is: the composite set that adopts the utility model circuit breaker-isolating switch; Circuit breaker and isolating switch are integral type; Reduced the direct coupling part of intermediate isolating switch and circuit breaker; Dwindle the cabinet volume greatly, reduced cost, and had the advantage of miniaturization.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model structural representation.
Among the figure: 1. pole, 2. sealing plate, 3. breaker mechanism, 4. isolating switch mechanism, 5. insulator, 6. copper bar, 7. the combined floodgate cutter head is 8. isolated blade, 9. final drive shaft.
Embodiment
The composite set of a kind of circuit breaker-isolating switch as shown in Figure 1; Have breaker mechanism 3, isolating switch mechanism 4, pole 1; Described breaker mechanism 3 and isolating switch mechanism 4 are connected to integral type through screw, and are fixed on sealing plate 2 one sides, and pole 1 is fixed on sealing plate 2 opposite sides; Be connected with on the lower wire end of pole 1 and isolate blade 8, the last leading-out terminal of pole 1 passes through the fixedly combined floodgate cutter head 7 of isolating switch of insulator 5.
Pole 1 inside is stretched out insulated tension pole and is passed sealing plate 2 and link to each other with opposite side breaker mechanism 3, the final drive shaft 9 of isolating switch mechanism 4 with isolate blade 8 and be connected.
When isolating switch mechanism 4 actions, impel final drive shaft 9 to rotate, isolate blade 8 rotations thereby drive, realize that isolating switch switches at combined floodgate, isolation, ground connection three stations.
When isolation blade 8 forwards closing position to, just realized that electric current through leading-out terminal on the pole 1, gets into pole 1; Pass through to isolate blade 8 from lower wire end; To combined floodgate cutter head 7, flow out through the copper bar 6 that connects combined floodgate cutter head 7 at last, realized the double function of isolating switch and circuit breaker.
