Among the figure 1 is circuit breaker operation mechanism, the 2nd, bellows seal, the 3rd, and insulated tension pole, the 4th is flexible coupling, the 5th, conductive clip, the 6th, lower carriage, the 7th, outlet seat, the 8th, vacuum interrupter, the 9th, insulating cylinder, the 10th, three-station, the 11st, bellows coupling, the 12nd, hermatic door, 13 are three station manipulation mechanisms.
Embodiment
To be flexible coupling 4, conductive clip 5 and lower carriage 6 be welded into parts, be installed on the moving conductive rod of vacuum interrupter 8.Again insulated tension pole 3 is screwed in the screwed hole of vacuum interrupter 8 moving conductive rods, use nut check.Above parts are packed in the insulating cylinder 9, fix with screw and insulating cylinder 9 at the quiet end of vacuum interrupter.Outlet seat 7 is screwed in the hole of insulating cylinder 9 and with lower carriage 6 is connected.The cutting blade of three-station 10 is fixed on the outlet seat 7, and working contact is installed on the insulating cylinder 9.Elder generation is installed in the grounding contact of three-station 10 on the hermatic door 12 by bent plate then, insulating cylinder 9 is installed on the hermatic door 12 again.Bellows seal 2 is packed into from the opposite side of hermatic door 12, and an end is connected with insulated tension pole 3 in being installed in insulating cylinder 9, and the blue face installation O RunddichtringO of the method for bellows seal 2 also is fastened on the hermatic door 12 with screw.Circuit breaker operation mechanism 1 is installed in hermatic door 12 opposite sides, and its output is connected with bellows seal 2.Bellows coupling 11 is packed into from the opposite side of hermatic door 12, and an end is connected with the action bars of three-station 10, and the blue face of the method for bellows coupling 11 is installed O RunddichtringO circuit breaker and is fastened on the hermatic door 12 with screw.Three-station operating mechanism 13 is installed in hermatic door 12 opposite sides, and its output is connected with bellows coupling 11.
Circuit breaker is to close to close, cut-off the operating current in loop or the functional unit of overload current.Circuit breaker operation mechanism 1 is the power source of circuit breaker, drives the circuit breaker action and makes its operating characteristics meet the requirement of product.Three station manipulation mechanisms 13 are power sources of three-station 10, and the cutting blade that drives three-station 10 rotates to the isolated location from the service position, rotates to earthing position again.Bellows seal 2 is the connecting links between circuit breaker operation mechanism and the circuit breaker, also is simultaneously the moving sealing element between them, movable sealing is changed into the static seal of O type circle by bellows.Bellows coupling 11 is the connecting links between three-station operating mechanism and the three-station, also is simultaneously the moving sealing element between them, movable sealing is changed into the static seal of O type circle by bellows.Be flexible coupling 4, conductive clip 5, lower carriage 6 and outlet seat 7 all be current-carrying elements.Insulated tension pole is the operating axis of actuating vacuum interrupter 8, and portion is equipped with touch spring within it simultaneously, provides confining force to overcome electric power can for vacuum interrupter 8.Vacuum interrupter 8 is that the operating current in loop or the electrovacuum element of overload current are closed, cut-off in the circuit breaker pass.Insulating cylinder 9 is insulating supports of installing and shielding vacuum interrupter, also is the installing rack of three-station 10 simultaneously.It adopts the epoxy injection moulding process, has higher intensity and shock resistance, bending resistance.The effect of three-station 10 is can be reliably by operating current and short-circuit current when the service position, utilizing the insulating capacity of fracture that the needs maintenance or the circuit of segmentation and charged circuit are isolated mutually when the isolated location, is the safety in order to ensure the maintainer when earthing position.When the cutting blade of three-station 10 rotates under the drive of operating mechanism and meshes with working contact, i.e. the contact in cutting blade and left side engagement in the accompanying drawing, three-station is positioned at the service position; When cutting blade was in vertical position, three-station was positioned at the isolated location; When cutting blade and grounding contact engagement, i.e. the contact on accompanying drawing cutting blade and right side engagement, three-station is positioned at earthing position.Hermatic door 12 is reference for installation of all elements, and the while also is that the vacuum circuit-breaker of band three-station is installed to the reference for installation on the switchgear.Three-station 10 is guillotine type structures, and its action drives by screw mandrel.Three-station 10 does not need a deciliter electric current, and the work of its deciliter electric current has been born by circuit breaker, so its action does not have rate request.
Can realize following interlock between the vacuum circuit-breaker of band three-station: when three-station was positioned at the service position, circuit breaker can carry out breaking-closing operating; When three-station was positioned at the isolated location, circuit breaker can carry out breaking-closing operating; When three-station is positioned at earthing position, must confirm that the quiet end of vacuum interrupter does not have electricity, circuit breaker just can carry out breaking-closing operating.Three-station in course of action, the circuit breaker No switching on.These interlocks are to realize by the mechanical interlocking between three-station and circuit breaker operation mechanism.
