Abstract
FIELD: electroheaters temperature regulators operated by alternating electrical current and using thyristors, thermal resistors and electronic means of control. SUBSTANCE: aim is to provide high accuracy of adjustment, stability, reliability and economical efficiency of regulator, to increase its service life and to decrease dimensions. Aim is realized by usage for control of balanced bridge with thermal resistor in one of arms and with zero-indicator acting on thyristor control - in diagonal. Thyristor is in series with electrical heater connected to alternating current network feeding bridge circuit. The circuit provides optimal time delay of starting pulses in respect to beginning of network working half-cycles. Thyristor triggering is exercised at instant of time, as anode voltage is already present in thyristor and it is sufficient for thyristor triggering and is close to minimum value as du/dt, di/dt and commutation interferences are minimal. EFFECT: high accuracy of adjustment, high stability, reliability and economical efficiency of regulator.
