Description
Technical field
The present invention relates to electrical device technical field, especially relate to a kind of novel capacitance switch structure, a kind of rectilinear structure adopting permanent-magnet manipulating mechanism switchs specifically.
Background technology
Being currently used in the capacitance switch on capacitance-adjustable transformer to be generally made up of housing, switch fuse, gas shield device, switch fuse is cut pass by drive mechanism, quick switching mechanism and choosing and forms. Static contact is arranged on the circumference of switch fuse bar frame, and moving contact is fixed on main shaft supporter. When needing capacity transfer, motor drives main shaft to rotate, and moving contact contacts with corresponding static contact and realizes transformer high-voltage winding " Y-�� " conversion and low pressure winding " connection in series-parallel " conversion, thus realizing capacity transfer purpose.
But owing to electric machine rotation is relatively slow, changing the appearance time is generally both needed to hundreds of millisecond, just slow owing to changing volume flow rate degree, for avoiding high-voltage coil and low-voltage coil to change the asynchronous voltage jump caused, then must connect with transition resistance R between moving contact main paying, and this resistance is easy to burn out. Also just slow because changing volume flow rate degree, it is easily generated electric arc when changing appearance, life-time service causes poor contact of contacts, and cooling oil impurity increases, and insulation declines; For avoiding this situation, also need to protect accordingly device, so that capacitance-adjustable transformer volume is relatively big, relatively costly.
Existing patent (number of patent application: 201120180913.8) provides a kind of conversion speed fast, and the permanent magnetic mechanism switch of reliable in action well solves the problems referred to above. But it is due to shunting switch system disc-shaped structure, for ensureing that insulation volume is relatively big, relatively costly; And Transformer Winding lead-in wire need to plate-like switch around wiring, inefficient.
