Background technology
The vacuum ring main unit volume of domestic market is all bigger at present; General vacuum switch and isolating switch are two independently electric elements, connect with lead when combination is used again, and therefore the volume ratio of common ring main unit is bigger; Cost is also high, can not satisfy the requirement of ring main unit miniaturization; For realizing the ring main unit miniaturization; The current SF6 that can only select for use inflates cabinet; Through in ring main unit, charging into SF6 gas (sulphur hexafluoride), alternate, the distance relatively of the conductor that can dwindle vacuum switch and isolating switch is avoided arc discharge; But one of gas of the destruction environment that SF6 gas is international convention to be assert should limit and eliminate gradually.
Existing vacuum looped network switch cubicle generally only has the function of on-load switch, if some occasion need have the function of cutting-off of short-circuit electric current, then needs breaker cabinet of additional configuration, has not only increased occupation space, has also increased cost.
The defective that existing vacuum looped network switch cubicle exists: take up room big, cost is high, the feature of environmental protection is poor.
Summary of the invention
Taking up room of existing vacuum looped network switch equipment is big, cost is high in order to overcome, the deficiency of feature of environmental protection difference, and the present invention provides a kind of minimizing to take up room, reduce production costs, have the fixed-sealing integrated and modularized vacuum looped network switch equipment of good environmental-protecting performance.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of 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; Said vacuum switch and isolating switch seal admittedly and are integration module; Said 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, and 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 said isolating switch is connected with said 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: said 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 through first and is connected with the quiet end of vacuum interrupter; The contact knife other end is corresponding with fixed contact respectively, and said separated fixed contact is connected with said band main bus bar formula sleeve pipe;
Further, isolator operating mechanism is interlocked with the vacuum switch operating mechanism mutually.
Technical conceive of the present invention is: said vacuum switch and isolating switch adopt epoxide resin automatic pressure gel APG to seal technology admittedly and are integrated into a module, need not 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; Scheme of designing of the present invention only need be reequiped existing ring main unit and got final product, and soon vacuum switch and isolating switch seal admittedly and be 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, and it is simple and compact for structure; Volume is little, and reliability is high; This technical scheme makes ring main unit be able under the prerequisite of environmental protection, realize miniaturization.
Beneficial effect of the present invention mainly shows: reduce taking up room, reduce production costs, having good environmental-protecting performance.
