Description
Technical field
The utility model relates to iec switch field, is specifically related to a kind of high-tension vacuum load isolating switch fuse combined electric apparatus.
Background technology
Combined electrical apparatus is comprised of isolation knife and vacuum interrupter, this three large assembly of fuse, insulating effect when isolation knife has been born combined floodgate and separating brake, and vacuum interrupter is born the effect of extinguish arcs.Fuse plays protective effect, has after a phase fuse blows, and the hammer-driven travel switch of fuse makes switch separating brake at once, reaches protective effect.Existing high-tension vacuum load isolating switch fuse combined electric apparatus, complex structure, in the situation that high pressure inlet wire cable is charged, replacing fuse that can not be safe, maintenance cost is higher.
Utility model content
The technical problems to be solved in the utility model is the defect that overcomes prior art, and a kind of high-tension vacuum load isolating switch fuse combined electric apparatus is provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of high-tension vacuum load isolating switch fuse combined electric apparatus of the utility model, it comprises isolating switch, metal framework, fuse, wall-penetrating type insulator, vacuum interrupter, operating mechanism and earthing; Described isolating switch and fuse are distributed in metal framework both sides, by wall-penetrating type insulator, are supported and are connected; Inner sealing one electric conductor of described wall-penetrating type insulator, described electric conductor connects the quiet end of described isolating switch and the upper end of described fuse; Described vacuum interrupter is arranged in the below of described fuse, and described operating mechanism is by vacuum interrupter deciliter described in insulated tension pole actuating.
Further, described in described wall-penetrating type insulator, between electric conductor, adopt epoxide resin material sealing.
Further, described vacuum interrupter comprises moving conductive end and quiet conducting end; Described moving conductive end is connected with described fuse lower end by being flexible coupling, and described quiet conducting end is connected with wire outlet seat by quiet support.
This combined electrical apparatus is for three-phase alternating current 40.5kV system, and an isolating switch, fuse, on-load switch, earthing often match.While opening isolating switch, can form an obvious isolation fracture, by interlocking device, make earthing ground connection simultaneously, ensure maintainer's safety.On-load switch can safety cut-out rated load electric current and certain overload current but can not cutting-off of short-circuit electric current, the short circuit current of combined electrical apparatus is cut off by fuse.
The beneficial effect that the utility model reaches is:
(1) this combined electrical apparatus adopts wall-penetrating type insulator structure, compares with traditional Split insulating minor structure, and structure is simpler, easier for installation.
(2) described wall-penetrating type insulator is inner has replaced copper bar connected mode with epoxide resin material sealing one electric conductor, has saved three insulators, can also reduce cabinet high simultaneously, has saved cost.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
