Title:
SATURABLE REACTOR FOR HIGH VOLTAGE PULSE GENERATOR
Document Type and Number:
Japanese Patent JPH01262609
Kind Code:
A
Abstract:

PURPOSE: To prevent heat generation during operation, remove deformation of a magnetic core and always maintain a good magnetic characteristic by arranging an insulator band material of a holding material on the inner and outer peripheries of a saturable iron core and causing a cooling medium to flow therebetween.

CONSTITUTION: The inner and outer peripheries of a ring-shaped saturable magnetic iron core 7 are held by the band-shaped insulating holding members 9a and 9b for being arranged between an inner tube and an outer tube of a double-wall cylindrical conductor. The double cylindrical conductor 1 has a function of a wiring, while an inner cylinder terminal and an outer cylinder terminal are selectively made an input terminal and an output terminal. The both ends of the double wall conductor are provided with an inflow hole 5 and an outflow hole 6 of a cooling medium in order to cool the saturable magnetic core of the cylinder conductor. The saturable magnetic core is so formed that a magnetic thin band is blanked in a ring for being laminated in a large number through the insulating layers. An amorphous thin band is favorable for improving a magnetic characteristic of the magnetic thin band and when this thin band is given a heat treatment before making the magnetic core, it is hard to heat during operation. When a saturable reactor according to this constitution is used for a high voltage pulse generation device, the device has a high output and change with the passage of time due to the deterioration of the magnetic core is prevented thereby obtaining a long life.
