Disclosed is an electrode for a vacuum interrupter, capable of reducing damage of contacts due to heat concentration to the center of the contacts, by reducing magnetic flux concentration to the center of the electrode, and capable of rapidly extinguishing an arc by diffusing the arc by forming a wide range of magnetic flux. The electrode for a vacuum interrupter comprises: a contact electrode plate configured to provide contacts; an inner coil electrode formed of one electric conductor having an open loop shape, and through which a current flows in a first rotation direction; an outer coil electrode formed of one electric conductor having an open loop shape, concentrically arranged with the inner coil electrode at an outer side of the inner coil electrode in a radius direction, and through which a current flows in a second rotation direction opposite to the first rotation direction parallel to the current flowing to the inner coil electrode; a first conductive pin formed of a conductive material, and configured to provide an electric current path by connecting the contact electrode plate and the inner coil electrode with each other; and a second conductive pin formed of a conductive material, and configured to provide an electric current path by connecting the contact electrode plate and the outer coil electrode with each other.

An apparatus for preventing withdrawing and insertion of a carriage of a circuit breaker is disclosed. When a circuit breaker main body is inserted, an interlocking unit operates by interworking with the carriage withdrawing and inserting preventing apparatus, and while the circuit breaker is being closed, a withdrawal and insertion handle prevents a lead screw from being rotated by the interlocking unit. Thus, when the circuit breaker performs a closing operation, unnecessary withdrawing and inserting operation of the carriage is basically prevented to thus prevent various safety accidents, a contact resistance, a temperature increase, and damage to a device resulting from a breakdown.

Disclosed is a vector modulator. The vector modulator can control the amplitude and phase of an input signal, by not using amplitude variable attenuators but using phase shifters. Further, the vector modulator has a simple configuration and enables an input signal to be exactly modulated. Furthermore, the vector modulator can modulate the phase of an input signal throughout all areas in the polar coordinate system.
