Title:
電磁反発駆動開閉装置
Document Type and Number:
Japanese Patent JP4065692
Kind Code:
B2
Abstract:
An electromagnetic repulsion drive switching device in which a contact-closing coil 19 and a contact-opening coil 20 are arranged to confront a repulsive member 18 having a conductivity, and in which a drive current is fed to a selected one of the individual coils 19, 20 from a capacitor 24 charged to a predetermined charge voltage by a charging power source 22, so that a stationary contact 15a and a movable contact 15b are brought into and out of contact by a repulsion force of the electromagnetic force generated between the coil 19, 20 and the repulsion member 18, characterized by comprising voltage control means 30 for controlling the output voltage of the charging power source 22 so that the peak value of the drive current may fall within a predetermined range with respect to a temperature change of the capacitor 24. As a result, even if the working temperature of the capacitor 24 changes, the drive current of the contact-closing coil 19 and the contact-opening coil 20 falls within a predetermined range.
