Abstract
The utility model discloses a kind of flexible connection structure of indoor high-voltage vacuum breaker solid sealed pole, it is characterized in that: together with first upper outlet 1, cushion block 2 being bolted on vacuum interrupter 3, seal 4 is placed under the formula that is flexible coupling in outlet 7, conductive clip 9 is cuboid formula structures, four one end of 8 of being flexible coupling are welded on four faces of conductive clip 9, and the other end is bolted on the inwall of lower outlet 7.On conductive clip 9, have one with the identical taper hole of vacuum interrupter 3 moving conductive rod taperings, conductive clip 8 is enclosed within on the moving conductive rod of vacuum interrupter 3.This structure is at conductive clip 9 rapidly upwards or while moving downward, drag minimization and there will not be clamping stagnation.In addition this structure be flexible coupling 8 and lower outlet 7 contacts area large, current density is little, area of dissipation is large, is particularly suitable for making the pole of large current class.
Description
Technical field
The utility model relates to the indoor high-voltage vacuum circuit breaker in a kind of electrical power distribution system, special relevant with the syndeton of the pole of electric current indoor HVAC vacuum circuit breaker greatly.
Background technology
In domestic electrical power distribution system, in great-current fixed sealed pole, moving conductive rod of vacuum arc extinguish chamber, with the connection of lower conductive seat, adopts the direct connected mode contacting with the fingertip spring on lower wire outlet seat of sliding friction piece mostly.
Because pole is the chief component of the main conductive circuit of whole circuit breaker, the quality of all pole performances has directly determined the performance of circuit breaker.This structure is because internal environment is more airtight, and sliding friction piece and lower wire outlet seat gap are smaller, so heat radiation is more difficult.The connecting lever movement locus that pole connects is on the other hand one section of camber line, if sliding friction piece and lower outlet concentricity are larger, with regard to the phenomenon that likely causes circuit breaker to occur there will be to refuse point, refuses to close, thereby affects the power supply of circuit in on/off switch process.If ensure less concentricity, whole technical process is comparatively complicated, and rate of finished products is lower, is difficult to ensure the consistency of product.
Utility model content
The utility model be connected with lower conductive seat for arc control device moving conductive rod in current solid-sealed polar pole used for vacuum circuit breaker difficult problem provide a kind of contact resistance little, heating less, good, the flexible Novel solid sealing post syndeton without clamping stagnation of radiating condition.
The technical solution of the utility model is: a kind of flexible connection structure of indoor high-voltage vacuum breaker solid sealed pole, comprises outlet, cushion block, vacuum interrupter, seal, lower outlet, conductive clip, is flexible coupling.It is characterized in that with bolt, upper outlet, cushion block, vacuum interrupter being fixed together, seal is placed in lower outlet, conductive clip is cuboid formula structure, and four one end that are flexible coupling are welded on conductive clip, and the other end is bolted on lower outlet inwall.On on conductive clip, have one with the identical taper hole of moving conductive rod of vacuum arc extinguish chamber tapering, conductive clip is enclosed within on the moving conductive rod of vacuum interrupter.
The Novel solid sealing post flexible connection structure that the utility model provides is flexible coupling and is fixed together with lower outlet inwall by four, has increased connecting portion conductive contact area, has reduced contact resistance, has increased again area of dissipation.And the activity space that is flexible coupling of pole inside is abundant, even if being one section of camber line, the running orbit of the connecting lever being connected with pole can not cause the clamping stagnation of circuit breaker in splitting or integrating lock process.This structure, without the requirement that ensures just can meet in the situation of conductive clip and the very little concentricity of moving conductive rod of vacuum arc extinguish chamber circuit breaker, makes production process simpler.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, upper outlet 2, cushion block 3, vacuum interrupter 4, seal 5, sliding friction piece 6, spring touch finger 7, lower outlet 8, be flexible coupling 9, conductive clip.
As shown in the figure, the utility model pole flexible connection structure, together with it is characterized in that first upper outlet 1, cushion block 2 being bolted on vacuum interrupter 3, seal 4 is placed under the formula that is flexible coupling in outlet 7, conductive clip 9 is cuboid formula structures, four one end of 8 of being flexible coupling are welded on four faces of conductive clip 9, and the other end is bolted on the inwall of lower outlet 7.On conductive clip 9, have one with the identical taper hole of vacuum interrupter 3 moving conductive rod taperings, conductive clip 8 is enclosed within on the moving conductive rod of vacuum interrupter 3.This structure is at conductive clip 9 rapidly upwards or while moving downward, drag minimization and there will not be clamping stagnation.In addition this structure be flexible coupling 8 and lower outlet 7 contacts area large, current density is little, area of dissipation is large, is particularly suitable for making the pole of large current class.
