Analysis of the circuit diagram of the two compressors' phase failure protection

Analysis of the circuit diagram of the two compressors' phase failure <br><br> Air compressor phase failure <br><br> circuit In the figure, KP is the electrical contact pressure gauge Ai is the CD4073 AND gate circuit, Az is the ~D4025 NOR gate circuit, and A3 is the CD4071 OR gate circuit. The 7806 three-terminal fixed integrated voltage regulator is used as the control circuit for the DC working power supply. When the AC power fails, the relay KA is released and the motor stops.
