Abstract

PURPOSE: To obtain desired time limit characteristics by changing the reference level (100 % point) of time limit chracteristics inversely proportional to the input electricity amount.
CONSTITUTION: The static relay consists of the input circuit 1 by which to convert AC input electricity amount to predetermined electricity amount, the time limit circuit 2 by which to draw out output after a predetermined time limit by starting on the electricity amount, the arithmetic circuit 3 by which to draw out a predetermined electricity amount by comparing the output of the time limit circuit 2 with the electricity amount, the integrating circuit 4 by which to integrate the electricity amount of the arithmetic circuit 3, and the output circuit 5 by which to draw out the relay output on the output of the integrating circuit 4. The constitution enables one to set up optionally operating time characteristic, to approximate it to thermal characteristic curve, and also to protect the optimum overload of motor circuit.
