Abstract
The utility model relates to the technical field of high-voltage electric appliances, and particularly relates to a main loop combination of a solid insulating vacuum circuit breaker and an isolating switch. The main loop combination is provided with an insulating cylinder, a vacuum interrupter, an isolating switch blade and the like, wherein the solid insulating vacuum circuit breaker is integrally connected with an isolating switch main loop, so as to assure that the main loop of each phase is located in the sealed insulating cylinder, the spacing distance between the circuit breaker and the vacuum interrupter is reduced, and the connecting distance between the circuit breaker and the isolating switch is reduced; therefore, the volume of the whole circuit breaker and the isolating switch is reduced and electric equipment has the advantages of miniaturization; the cost is greatly reduced due to that the quantity of copper bars connected at the middle part is reduced; and in addition, the main loops of all the phases, which are integrally connected, are arranged in the same closed space of the insulating cylinder, so that the independence of the main loops is improved and the electric equipment can be stably operated under a rugged environment.
Description
Technical field
The utility model relates to high voltage electrical apparatus technical field, especially a kind of solid isolated vacuum circuit breaker and the combination of isolated switch main loop.
Background technology
Solid isolated vacuum circuit breaker and isolating switch major loop are installed separately in the present high-voltage board; Middle through the copper bar connection, in order to guarantee insulation, require installing space bigger; Can not satisfy the demand of current social to the electric equipment miniaturization; If in adverse circumstances, use, electric equipment is subject to external interference and influences the operation of its normal and stable, causes the accident easily.
The utility model content
In order to overcome vacuum circuit-breaker and the dispersion of isolating switch major loop in the existing high-voltage board, copper bar connects the more and bulky shortcoming of cabinet, and the utility model provides a kind of solid isolated vacuum circuit breaker and the combination of isolated switch main loop.
The utility model solves the technical scheme that its technical problem adopted: the insulating cylinder device of a kind of solid isolated vacuum circuit breaker and isolated switch main loop sets; Have insulating cylinder, vacuum interrupter; Isolating switch blade etc.; The isolating switch blade directly with circuit breaker under the outlet bearing link to each other, isolating switch combined floodgate station cutter head and connect copper bar and cast directly in the insulating cylinder is with the shared insulating cylinder of vacuum circuit-breaker major loop; The insulating cylinder inner sealing has the isolating switch blade; Vacuum circuit-breaker is with vacuum interrupter and connect copper bar, and the circuit breaker lower wire end is directly connected to the inner vacuum interrupter upper end of circuit breaker major loop, and the vacuum interrupter lower end is through being flexible coupling and bearing links together; The isolating switch blade is connected with bearing; Directly inner with the being cast in insulating cylinder copper bar of last leading-out terminal is connected, whenever passes through mutually that cable is connected the loop of an integral body of formation in last leading-out terminal and lower wire end and the cabinet.
The isolating switch blade externally effect of mechanism rotates down, realizes that three stations of isolating switch switch, and vacuum circuit-breaker can be connected with operating mechanism through the insulated tension pole that is connected with the vacuum interrupter lower end, realizes the on/off switch of circuit breaker.
The beneficial effect of the utility model is: the utility model solid isolated vacuum circuit breaker and isolating switch major loop connect one; Guarantee that every phase major loop is all inner at the insulating cylinder of a sealing, reduce the phase spacing of circuit breaker and isolating switch, reduced the distance that is connected between circuit breaker and the isolating switch; Thereby reduced the volume of whole circuit breaker and isolating switch; Make electric equipment possess the advantage of miniaturization, and, greatly reduce cost because the centre connects the minimizing of copper bar; In addition, the every phase major loop that fuses all in the space of same insulating cylinder sealing, has improved the independence of major loop, makes the electric equipment also can stable operation at rugged environment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Among the figure: 1. go up leading-out terminal, 2. insulating cylinder, 3. isolating switch blade, 4. isolating switch combined floodgate station cutter head, 5. insulated tension pole, 6. bearing, 7. vacuum interrupter, 8. copper bar 9. is flexible coupling, 10. lower wire end.
