Wiring is an important link in the group hoist electric hoist. Now we will give you a detailed introduction to the group hoist electric hoist, which will help you better understand. The first step is to first connect the two buttons that control forward and reverse in series first, then connect the two buttons that control forward and reverse, and connect them to the end of the stop button. The other end of the stop button is ready to be connected to the power supply, and then the normally open auxiliary auxiliary contacts of the forward and reverse main contactors are respectively connected in parallel to the corresponding two ends of the corresponding start button, and then the normally closed auxiliary auxiliary contacts of the respective main contactors are connected in series to In the start circuit of the other party, it means that the normally-closed forward connection is connected in series at the end of the reverse start button. The corresponding normally-closed contact of the reverse direction should be connected in series with the end of the forward start button to play an interlocking role. During normal running, the normally closed contactor auxiliary contact will disconnect the reverse starting circuit, and the reverse is still the reason. This is to avoid pressing the button at the same time to form a phase-to-phase short circuit}, and then The other ends of the two normally closed contacts are respectively connected to the corresponding coil section of the main contactor of the starting circuit {that is, the loop that controls the forward rotation is connected in series with the coil section of the forward contactor, and the control circuit is reversely started It is connected in series with the end of the reversed main contactor coil. This should be careful not to confuse} Connect the other ends of the two coils and connect them to the end of the normally closed contact of the thermal relay. The other end is ready to be connected to the neutral point N or another phase line. It is necessary to observe the voltage of the main contactor coil {220V is connected to the neutral point N. If it is 380v, it is connected to the other phase line}. At this time, it needs to be controlled. The forefront of the loop is the end of the connection button that is ready to be connected to the power supply. Before connecting the phase line system, it needs to pass through a safe control. Now as long as the control loop is connected, it is enough.
