Title:
HIGH-FREQUENCY BIPOLAR DISCONNECTOR
Document Type and Number:
Japanese Patent JP2014130785
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high-frequency bipolar disconnector capable of reducing an inductance caused by a current loop, reducing an occupied area, reducing influences of an impact force by a mechanism for driving a movable electrode, and being suitable for a high-frequency and large-current (several kHz to several hundreds kHz, several hundreds A or more) use application.SOLUTION: A movable electrode 1 and a plurality of fixed electrodes 2 are provided symmetrically so as to be opposed to each other, on both sides of a base plate 10. On one side of the base plate 10, the movable electrode 1 is driven by a first drive part to contact with or separate from the plurality of fixed electrodes 2. On an opposite side of the base plate 10, the movable electrode 1 is driven by a second drive part to contact with or separate from the plurality of fixed electrodes 2. Thus, on both sides of the base plate 10, a first current path including the fixed electrodes 2 and the movable electrode 1 is formed along the base plate 10, and a second current path including the fixed electrodes 2 and the movable electrode 1 are formed along the base plate 10. Impact forces that the first and second drive parts give the base plate 10 are mutually cancelled.
