Abstract
What the utility model discloses a kind of on-load switch removes isolation structure.It is in casing (1), and outgoing line side sleeve pipe terminal outlet (7) is connected with conducting block (5), after conducting block (5) is connected with a deciliter shaft insulation (4), is directly connected with inlet wire side sleeve pipe terminal outlet (2) by be flexible coupling (3).This isolation structure that goes can not only make on-load switch meet its functional requirement, and structure is simple, and easy to assembly, cost is low, and potential faults point is few, failure rate is low.
Description
Technical field
What the utility model related to a kind of post load switch removes isolation structure.
Background technology
Existing pole vacuum on-load switch internal structure, mainly comprise built-in isolation switch and vacuum interrupter two parts, namely in seal case, the outlet of outgoing line side sleeve pipe terminal is connected with vacuum interrupter, and vacuum interrupter connects with conducting block, and conducting block to be connected with isolation knife moving contact by being flexible coupling again, the sleeve pipe terminal outlet of inlet wire side is then connected with isolation switch fixed contact, last isolation switch moving contact is connected with isolated insulation axle again, and conducting block is connected with a deciliter shaft insulation again, as accompanying drawing 1.This on-load switch structure is comparatively complicated, and cost is high, and assembling is inconvenient, and potential faults place is many, and failure rate is high.
Summary of the invention
The purpose of this utility model be design a kind of on-load switch remove isolation structure.
The technical solution of the utility model is: a kind of post load switch remove isolation structure, comprise casing, vacuum interrupter, the sleeve pipe terminal outlet of inlet wire side, the outlet of outgoing line side sleeve pipe terminal, conducting block, deciliter shaft insulation; Principal character is that the outlet of outgoing line side sleeve pipe terminal is connected with conducting block, after conducting block is connected with a deciliter shaft insulation, to be directly connected with the sleeve pipe terminal outlet of inlet wire side by being flexible coupling.
During combined floodgate, be placed in by operating mechanism outside seal case, manual operation switch lever, operating mechanism drives shaft insulation to rotate, and deciliter shaft insulation drives vacuum interrupter to close, and completes combined floodgate, turning circuit (the full energy of now operating mechanism energy accumulation spring storage); During separating brake, energy accumulation spring releases energy, and operating mechanism drives deciliter shaft insulation to rotate, then the vacuum interrupter that links, and makes it separating brake power-off.
The on-load switch that the utility model provides remove isolation structure, eliminate isolation switch and isolated insulation axle, not only reduce costs, easy to assembly, reduce potential faults, and this kind of structure can meet the functional requirement of on-load switch completely.
Accompanying drawing explanation
Accompanying drawing 1 is existing on-load switch internal structure schematic diagram.
Accompanying drawing 2 removes the schematic diagram of isolation structure for the utility model on-load switch.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, casing 2, inlet wire side sleeve pipe terminal outlet 3, be flexible coupling 4, deciliter shaft insulation 5, conducting block 6, vacuum interrupter 7, the outlet of outgoing line side sleeve pipe terminal
As shown in Figure 2, the utility model on-load switch remove isolation structure, comprise casing, vacuum interrupter, the sleeve pipe terminal outlet of inlet wire side, the outlet of outgoing line side sleeve pipe terminal, conducting block, deciliter shaft insulation; Principal character is in casing 1, and outgoing line side sleeve pipe terminal outlet 7 is connected with conducting block 5, after conducting block 5 is connected with deciliter shaft insulation 4, directly 3 to be connected with inlet wire side sleeve pipe terminal outlet 2 by being flexible coupling.
During combined floodgate, be placed in by operating mechanism outside casing 1, manual operation switch lever, operating mechanism drives deciliter shaft insulation 4 to rotate, and deciliter shaft insulation 4 drives vacuum interrupter 6 to close, and completes combined floodgate, turning circuit (the full energy of now operating mechanism energy accumulation spring storage); During separating brake, operating mechanism energy accumulation spring releases energy, and operating mechanism drives deciliter shaft insulation 4 to rotate, then the vacuum interrupter 6 that links, and makes it separating brake power-off.
Claims (1)
1. on-load switch remove an isolation structure, comprise casing (1), inlet wire side sleeve pipe terminal outlet (2), be flexible coupling (3), deciliter shaft insulation (4), conducting block (5), vacuum interrupter (6), outgoing line side sleeve pipe terminal outlet (7); It is characterized in that: in casing (1), outgoing line side sleeve pipe terminal outlet (7) is connected with conducting block (5), after conducting block (5) is connected with a deciliter shaft insulation (4), is directly connected with inlet wire side sleeve pipe terminal outlet (2) by be flexible coupling (3).
