Below in conjunction with accompanying drawing, the technical characteristic above-mentioned and other to the present invention and advantage are clearly and completely described,
Obviously, described embodiment is only the section Example of the present invention, rather than whole embodiments.
The fingertip high current rotary separation switch as shown in figure 1, one kind is flexible coupling, including fixed frame 1, upper static contact group
Part 5, lower static contact component 2, contact tube porcelain bottle sleeve component 3 and the component of earthed switch 4.Fixed frame 1 is three-phase chassis altogether,
Using 304 stainless steel materials that demagnetize, upper static contact component 5 and lower static contact component 2 are respectively arranged on the both sides of fixed frame 1, lead
Electric pole porcelain bottle sleeve component 3 includes some porcelain bottle sleeves 32 of contact tube 31 being made up of contact tube 31 and porcelain bottle sleeve 32, conductive
The axial both ends of pipe 31 connect upper static contact component 5 and lower static contact component 2 respectively.Two aluminium are provided among fixed frame 1 to close
The rotating shaft of gold, for fixing the porcelain bottle sleeve 32 of contact tube 31, realize that rotating 65 ° of controlling switches closes transfer work, chassis bottom
It is grounded rotating shaft 41 and is used for dead earth 4 components of switch.The lower end of fixed frame 1 is additionally provided with ground connection rotating shaft 41, for dead earth
Switch 4 components.In figure, the component of earthed switch 4 and contact tube porcelain bottle sleeve component 3 of bold portion are "on" position, dotted line part
The component of earthed switch 4 and contact tube porcelain bottle sleeve component 3 divided is gate-dividing state.Switch closing and switch opening process, three-phase are carried out simultaneously.
As shown in Fig. 2 the component of earthed switch 4 includes ground connection rotating shaft 41, the busbar 42 that confluxes, earthing 43 and is flexible coupling 44,
Rotating shaft 41 is grounded in fixed frame 1, the corresponding ground connection rotating shaft 41 of the busbar 42 that confluxes is in fixed frame 1, the He of earthing 43
It is flexible coupling 44 located at confluxing on busbar 42.Its implementation process is：Busbar 42 conflux by the short circuit of three-phase ground knife 43, is then aggregated into
