Abstract
PURPOSE: To secure a free adjustment for the differential temperature by switching the active temperature setting element connected to the gate circuit in accordance with the heat-sensitive action of the heat-sensitive thyristor.
CONSTITUTION: Load 1, the object of the temperature control, is connected to power source 2, and main thyristor 3 to control the load current is connected to load 1. Furthermore, the circuit comprising resistance 4, diode 5 and resistance 6 is connected in parallel to thyristor 3 to control thyristor 3. At the same time, the series circuit consisting of heat-sensitive thyristor 7 which senses to the temperature of load 1, constant-close contact relay 8 inserted into the anode circuit of thyristor 7 plus switching temperature setting resistance 9 and 10 is connected previously to the series circuit of load 1 and thyristor 3. In such constitution, the power supplied to load 1 is controlled by thyristor 3, and the temperature of thyrister 7 increases as the temperature of load 1 rises up. Thus, contact 8b provided to relay 8 is turned on/off in order to obtain the fixed temperature
