The figure shows the single-phase thyristor zero trigger electric furnace temperature control circuit. This temperature device is composed of the signal detection temperature control circuit, the zero detection circuit, cycle switch, trigger control and digital display etc. Itis used withXCT-101 temperature control meter together. It can monitor the 6 ~ 8 kW single-phase thyristor zero trigger electric furnace temperature. The temperature and thermal insulation are ajustable in 1% ~ 99%. The winding I1 of transformer B1, D1 ~ D4, D6, C1, BG1 and other components form the zero pulse detection circuit, IC2-l (1 / 4 CD4011) is the controlling door, and in the effect of the pulse output by cycle switch (IC1), it outputs a group of zero-crossing detection pulse, which is inverting amplified by BG2 and output by isolated transformer BG3.
