Abstract
The utility model discloses a kind of SF
6gas-filled type ring main unit fuse interlock, this earthing device is after the fusing of disconnected device, striker action wins (2) in succession by striker, thus drive interlock plate (3), keyset (5), interlocking top board (7) and (8) action in flakes of operating mechanism separating brake semiaxis, thus the interlock of disjunction on-load switch when realizing fuse blows.This interlock, fully uses transmission mechanics principle, and manufacture craft is simple, and cost is low, easy for installation, simple to operate, flexible.
Description
Technical field
The utility model relates to a kind of SF
6gas-filled type ring main unit fuse interlock.
Background technology
SF
6in gas-filled type ring main unit, transformer load loop generally adopts switch-fuse combination scheme, and require on-load switch and fuse reciprocal interlocking, when used interlock is generally fuse blows, in fuse unit, lateral impact power is converted to power vertically upward, because it is all insulating part, when just causing conversion, the loss of interlocking power is comparatively large, and insensitive phenomenon appears in interlocking sometimes, therefore need redesign a kind of SF
6gas-filled type ring main unit fuse interlock.
Utility model content
The purpose of this utility model is to design a kind of SF
6gas-filled type ring main unit fuse interlock.
The technical solution of the utility model is: a kind of SF
6gas-filled type ring main unit fuse interlock, be characterised in that, cabinet fixes interlock plate by swivel nut, interlock plate and fuse striker are won in succession and are close to, and with by support set, the keyset be fixed on cabinet is connected, and keyset is connected with interlocking top board, interlocking top board and operating mechanism separating brake semiaxis are close in flakes, which forms whole interlock.SF
6after gas-filled type ring main unit fuse blows, striker action is won in succession by striker, thus drives interlock plate, keyset, interlocking top board and operating mechanism separating brake semiaxis in flakes, thus the object of disjunction on-load switch when realizing fuse blows.
The SF that the utility model provides
6gas-filled type ring main unit fuse interlock, the interlock of disjunction on-load switch when not only can realize fuse blows.And cost is low, easy for installation, regulate simple, flexible operation.
Accompanying drawing explanation
Fig. 1 is the utility model SF
6the Facad structure schematic diagram of gas-filled type ring main unit fuse interlock embodiment;
Fig. 2 is side structure schematic diagram (when fuse does not fuse) embodiment illustrated in fig. 1;
Fig. 3 is side structure schematic diagram (during fuse blows) embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, ring network cabinet body 2, striker win 3 in succession, interlock plate 4, swivel nut 5, keyset 6, support set 7, interlocking top board 8, operating mechanism separating brake semiaxis in flakes.
As shown in drawings, the utility model SF
6gas-filled type ring main unit fuse interlock, fix interlock plate 3 by swivel nut 4 on cabinet 1, interlock plate 3 and fuse striker are won in succession and 2 to be close to, and with by support set 6, the keyset 5 be fixed on cabinet is connected, and keyset 5 is connected with interlocking top board 7, interlocking top board 7 and operating mechanism separating brake semiaxis 8 to be close in flakes, which forms whole interlock.
The interlock that the utility model provides, after disconnected device fusing, striker action wins 2 in succession by striker, thus drives interlock plate 3, keyset 5, interlocking top board 7 and operating mechanism separating brake semiaxis 8 actions in flakes, thus the interlock of disjunction on-load switch when realizing fuse blows.
The interlock that the utility model provides, fully uses transmission mechanics principle, and manufacture craft is simple, and cost is low, easy for installation, regulates simple, flexible operation.
