Y-△ started air compressor control circuit

Using electric contact pressure gauge KP control, the gas tank pressure can be automatically maintained at o. Between 09～
0.12MPa. Can be controlled automatically and manually. When the contactors KMi and KMz are closed, the motor is connected in a Y shape and starts to reduce voltage;
when KMi and KM3 are connected, the motor is connected in a △ shape and runs at full voltage.
