The technical scheme that its technical problem that solves the utility model adopts is:
A kind of environment-friendly type fixed-sealing integrated and modularized vacuum looped network switch equipment, comprise cabinet, be installed in band main bus bar formula sleeve pipe, vacuum switch, isolating switch, current transformer and earthed switch in the cabinet, described vacuum switch and isolating switch seal admittedly and are integration module, described vacuum switch comprises solid-sealing vacuum arc control device, insulated tension pole and vacuum switch operating mechanism, vacuum switch operating mechanism and insulated tension pole interlock, the insulated tension pole upper end links to each other with the moved end of vacuum interrupter; The quiet end of vacuum interrupter is connected with isolating switch, and described isolating switch is connected with described band main bus bar formula sleeve pipe; The moved end of vacuum interrupter lower end first is flexible coupling and links to each other with the lower wire end of vacuum switch; Earthed switch is connected with the linkage of isolator operating mechanism interlock.
As preferred a kind of scheme: described isolating switch comprises fixed contact, contact knife, the rotating insulated macro-axis of isolation, second being flexible coupling and isolator operating mechanism of being connected with the quiet end of vacuum interrupter, isolating rotating insulated macro-axis links to each other with isolator operating mechanism, contact knife one end is hinged with the rotating insulated macro-axis of isolation, while contact knife one end is flexible coupling by first and is connected with the quiet end of vacuum interrupter, the contact knife other end is corresponding with fixed contact respectively, describedly is connected with described band main bus bar formula sleeve pipe every fixed contact;
Further, isolator operating mechanism is interlocked mutually with the vacuum switch operating mechanism.
Technical conceive of the present utility model is: described vacuum switch and isolating switch adopt epoxide resin automatic pressure gel APG to seal technology admittedly and are integrated into a module, do not need to vacuumize, and also need not to fill insulating gas.
With respect to the situation that needs a breaker cabinet of additional configuration in the prior art, the scheme of the utility model design only need be reequiped existing ring main unit and be got final product, soon vacuum switch and isolating switch seal admittedly and are integration module, substitute existing Solid-sealing vacuum load switch module with the solid sealing type vacuum circuit breaker module, the function that can have cutting-off of short-circuit electric current, with respect to prior art, reduced taking volume, and reduced cost.
Admittedly it is isolated with the charged workpiece of each corresponding isolating switch and vacuum switch to seal integration module, improved the class of insulation, compared with prior art, the utility model need not vacuumize and charge into insulating gas between insulator He in the cabinet, it is simple and compact for structure, volume is little, the reliability height; This technical scheme makes ring main unit be able to realize miniaturization under the prerequisite of environmental protection.
The beneficial effects of the utility model mainly show: reduce taking up room, reduce production costs, having good environmental-protecting performance.
