Description
Technical field
The utility model relates to a kind of solid insulation ring main unit main insulation module, belongs to solid insulation ring main unit technical field.
Background technology
Vacuum interrupter in prior art main insulation module is vertical layout mostly, and operating mechanism is placed in main insulation module top; The bus connected mode that main insulation module adopts is that male-tapered connects.More than there is following drawback in design: because operating mechanism is placed in the top of main insulation module, and solid insulation ring main unit also will ensure that the cable of more than 650mm connects height, causes the operation excessive height of solid insulation ring main unit; Adopt male-tapered bus connected mode, not only increase the size of main insulation module, and the complex structure of bus, size is also larger.
Utility model content
The utility model is in order to address the aforementioned drawbacks, devise a kind of main insulation module of solid insulation ring main unit, by changing the arranged direction of vacuum interrupter and the connected mode of bus, reduce the operation height of solid insulation ring main unit, reduce bus overall dimension and simplify the connected mode of bus.
The technical solution adopted in the utility model is:
A kind of solid insulation ring main unit main insulation module, comprise epoxy body, isolation knife fixed contact, vacuum interrupter and conductor, vacuum interrupter casting on flat is in epoxy body, vacuum interrupter and conductor are bolted to connection, epoxy body is provided with cable joint connecting hole, cable joint connecting hole bonding conductor; Epoxy body is provided with some bus connecting holes; Epoxy body is provided with isolation knife motion chamber, the end of isolation knife fixed contact is cast in epoxy body, isolation knife motion chamber is stretched in another end of isolation knife fixed contact, isolation knife motion can install isolation knife in chamber, the middle part of isolation knife connects insulated tension pole, operating mechanism drives insulated tension pole, and isolation knife can realize closing a floodgate, isolating and grounding function.
Further, the diameter in bus connecting hole is less than the diameter of bus, and bus comprises copper rod and is wrapped in the silicon rubber outside copper rod, the inwall crimp of silicon rubber and bus connecting hole.
Further, the side in isolation knife motion chamber is provided with watch window.
The good effect that the utility model has is: the operation height reducing solid insulation ring main unit, reduces bus overall dimension and simplify the connected mode of bus.More meet the requirement of solid insulation ring main unit compactedness.

Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment:
A kind of solid insulation ring main unit main insulation module, comprise epoxy body 3, isolation knife 5, isolation knife fixed contact 1, vacuum interrupter 2 and conductor 4, as Fig. 1 and Fig. 2, vacuum interrupter 2 casting on flat is in epoxy body 3, vacuum interrupter 2 and conductor 4 are bolted to connection, epoxy body 3 is provided with cable joint connecting hole 33, and the bottom of main insulation module is provided with cable joint connecting hole 33, to change cable joint.Cable joint connecting hole 33 bonding conductor 4.
In order to reduce the operation height of solid insulation ring main unit, by horizontal for vacuum interrupter 2 sealing in epoxy body 3, such operating mechanism just can be arranged in the front portion of solid insulation ring main unit, but not top.Vacuum interrupter 2 is connected by M12 bolt, bullet pad, plain cushion with conductor 4.
Epoxy body 3 is provided with some bus connecting holes 32.Conveniently bus 7 connects and reduces the size of bus 7, epoxy body 3 arranges three circular holes, and the size relationship between circular hole and bus 7 meets: other two bore dias of external diameter < having the bore dia < bus 7 of isolation knife fixed contact 1.As Fig. 3, the silicon rubber 72 that bus 7 comprises copper rod 71 and is coated on outside copper rod 71, silicon rubber 72 and circular-hole internal-wall crimp, to solve the Insulation Problems of bus 7 joint, the structure of bus 7 also becomes simple simultaneously.The bus 7 that the bus connecting hole 32 that epoxy body 3 is arranged can realize between solid insulation ring main unit different function units easily connects, and bus 7 structure is simple, compact size.
Epoxy body 3 is provided with isolation knife motion chamber 31, the end of isolation knife fixed contact 1 is cast in epoxy body 3, isolation knife motion chamber 31 is stretched in another end of isolation knife fixed contact 1, isolation knife 5 can be assembled in isolation knife motion chamber 31, the middle part of isolation knife 5 connects insulated tension pole 6, operating mechanism drives insulated tension pole 6, and isolation knife 5 can realize closing a floodgate, isolating and grounding function.
In the specific implementation, isolation knife 5, when in power transmission, rotates to closing position by operating mechanism by the solid insulation ring main unit in the present embodiment, namely contacts with isolation knife fixed contact 1, and then by means of operating mechanism by 2-in-1 for vacuum interrupter lock.
When power-off, the opening button of trigger mechanism, by vacuum interrupter 2 cut-off loop, by operating mechanism, rotates to isolated location by isolation knife 5, can realize sub-switching operation; Isolation knife 5 is rotated to earthing position, can service work be carried out.
The side in isolation knife motion chamber 31 forms watch window 8.By the window that isolation knife motion chamber 31 is formed, from the left side of main insulation module, can be observed the location status of isolation knife 5, do not need additionally to open up a watch window 8.A/B/C three-phase main insulation module can share a secondary mould and produce.
