Abstract
PURPOSE: To make a relay to have strong anti-time and super anti-time characteristics, by providing a function generating circuit whose input is direct current voltage in which output of a transformer proportioned to alternating current input is converted to direct current, and forming so as to vary detected level of a level detector with output of this function generating circuit.
CONSTITUTION: An amplifier 13 of a function generating circuit 8 generates output a3 in which output a2 of an amplifier 12 and terminal voltage E2 are summed up. If this output a3 is used as level setting signal of a level detector 6, input current of a current transformer, or output voltage of commutation smoothing circuit 3, is greater, detection with the level detector 6 is faster. Therefore, so-called strong anti- time or super anti-time characteristics, or operation time is faster than that of constant speed of detecting level can be obtained.
