Liquid level relay schematic diagram，The water level of the water tank is too low（Lower than the yellow wire terminal）when，The first level is low，The triode is in a cut-off state，The collector is high；The second triode base has enough current to pass through，Triode drink and conduction，relay（K）It has to be electrocuted，Normally open contact（2、3foot）Normal close，The external contactor is electrically drawn、The pump pumps the water supply tank。
The working principle of frequency converter，The working principle of the inverter is to control the main circuit through the control circuit，A rectifier in the main circuit converts alternating current to direct current，The DC intermediate circuit smooths the DC current，The inverter finally converts the direct current back into alternating current at the desired frequency and voltage，Part of the frequency converter will also be added in the circuitCPUisocomponent，To perform the necessary torque calculations。
The working principle of frequency converter，In recent years，With power electronics technology、The development of microelectronics and large-scale integrated circuits，The improvement of the production process and the reduction of the price of power semiconductor devices，Frequency conversion speed regulation is more and more used in industry。How to choose the frequency conversion with good performance and apply it to industrial control。
