Description
Technical field
The present invention relates to a kind of induction cavity magnetic core resetting device, belong to a kind of induction cavity magnetic core electric pulse that resets and introduce mechanism.
Background technology
Induced voltage superimposer (IVA) is to utilize the several induction cavities of electromagnetic induction principle with several pulses feed-in parallel connection in a certain order, produces high voltage in same secondary stack.Wherein magnetic core must operate at the unsaturation state, in order to make full use of magnetic core, needs magnetic core is resetted before main pulse arrives.Way commonly used: utilize elementary or secondary introducing resetting current, it is the inner wire that DC power supply is connected to successively different induction cavities with a mechanical piston, feed-in electric current (～100A, several seconds time) produces the magnetic field of an a few tenths of oersted in amorphous magnetic core then.But when induction cavity is driven by a common clock, to the several magnetic cores of parallel connection simultaneously magnetic cores to reset may be difficult, not only because need bigger magnetic core resetting current, make the magnetic core resetting current difference that is assigned on the different magnetic cores owing to connect the variant meeting of resistance simultaneously, it is inhomogeneous and insufficient to cause different induction cavity magnetic cores to reset.
Summary of the invention
Technical problem to be solved by this invention is, form the induction cavity system that line drives several parallel connections simultaneously for one, for each induction cavity provides independent magnetic core resetting structure, guarantee that the independent magnetic core of each induction cavity resets, can not impact, can make each induction cavity magnetic core resetting current identical other induction cavities.
The present invention has designed a piston type induction cavity magnetic core resetting device.Design philosophy of the present invention is to add a mechanical switch between the dull and stereotyped transmission line of all induction cavities feed-in in parallel and each induction cavity, this switch peace board transmission line when magnetic core resets disconnects, realize that the independent magnetic core of each induction cavity resets, all induction cavities are burst and are connected with dull and stereotyped transmission line by the reciprocating machine switch into electrode when the main pulse feed-in, and main pulse is normally burst into each induction cavity.Consider that induction cavity magnetic core resetting device will pass through magnetic core reset pulse electric current and main pulse electric current respectively, so this mechanism design is cylindric piston mechanism, the little current impulse of low pressure also can be adopted the switch of other shapes.Basic composition of the present invention comprises the fixed piston tube electrode of fixedlying connected with an induction cavity angle transmission line, a movable piston motion electrode, piston electrode is by motion, can connect magnetic core reset pulse peace board transmission line inner core feed-in main pulse respectively, another one is exactly the driver part of driven plunger motion electrode, and the piston motion of cylinder dress piston mechanism can be adopted spring, pneumatic or electronic the driving as required among the present invention.
