Abstract
The utility model relates to a vacuum breaker switching-off mechanism with buffering. The mechanism comprises a casing. The casing is provided with an insulation sleeve; one side of the insulation sleeve is provided with a current transformer; the output side of the current transformer is rotationally connected with an isolation knife; the intermediate position of the isolation knife is connected with an insulation pull bar; the free end of the isolation knife is connected with an insulator; and the other end of the insulator is connected with an isolation switch support. By employing such a technical scheme, the isolation knife is driven by the current transformer to work, and then the isolation knife drives the insulation pull bar to move, such that the effect of a conventional switching-off spring is replaced, and since the spring resilience of the conventional switching-off spring is not very reliable, i.e., an elasticity effect force is generated, the conventional structure can be replaced by the structure provided by the utility model, such that it is ensured that the service life of the vacuum breaker switching-off mechanism can be improved.
Description
Technical field
The utility model belongs to the assembly of vacuum circuit-breaker, is specifically related to a kind of vacuum circuit-breaker brake separating mechanism with buffering.
Background technology
Vacuum circuit-breaker of the prior art in use, its separating brake and combined floodgate carry out work realization by tripping spring and switching-in spring, but after using for a long time, aging due to tripping spring and switching-in spring, there is unsettled situation in the restoring force of its spring, the combined floodgate of its vacuum circuit-breaker and separating brake there will be the collision of rigidity, make vacuum circuit breaker body inside impaired.
Summary of the invention
The utility model, in order to solve the technical problem of mentioning in background technology, provides a kind of vacuum circuit-breaker brake separating mechanism with buffering.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of vacuum circuit-breaker brake separating mechanism with buffering, comprise casing, casing is provided with insulating sleeve, insulating sleeve one side is provided with current transformer, the outlet side of current transformer is rotationally connected an isolation knife, the centre position of isolation knife connects an insulated tension pole, the free end connecting insulator of isolation knife, and the other end of insulator connects isolating switch support.
On isolating switch support, rotate and be provided with an isolator operation handle.
Adopt after above technical scheme: the utility model drives isolation knife to work by current transformer, then isolation knife drives insulated tension pole motion again, thereby replaced the effect of traditional tripping spring, because the spring of traditional tripping spring is replied, there is certain unreliability, there will be elastic acting force, by above structure, replaced, can guarantee that be improved the useful life of the brake separating mechanism of this vacuum circuit-breaker.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of vacuum circuit-breaker brake separating mechanism with buffering, comprise casing 1, casing 1 is provided with insulating sleeve 2, insulating sleeve 2 one sides are provided with current transformer 3, and the outlet side of current transformer 3 is rotationally connected an isolation knife 4, and the centre position of isolation knife 4 connects an insulated tension pole 5, the free end connecting insulator 6 of isolation knife 4, the other end of insulator 6 connects isolating switch support 7.
For this, use novel all parts to explain:
1) on isolating switch support 7, rotate and be provided with an isolator operation handle 8.
Adopt after above technical scheme: the utility model drives isolation knife to work by current transformer, then isolation knife drives insulated tension pole motion again, thereby replaced the effect of traditional tripping spring, because the spring of traditional tripping spring is replied, there is certain unreliability, there will be elastic acting force, by above structure, replaced, can guarantee that be improved the useful life of the brake separating mechanism of this vacuum circuit-breaker.
