Electric plow control circuit

The power cord of agricultural electric plows and electric rakes must use four
-core rubber cables , one of which is used as a grounding
wire, and the tractor shell must be reliably grounded.
The power supply on the two traction machines is led from the same distribution box at the head of the field
to a four-core cable and sent to the power branch box. The power branch box has one in and two out (respectively connected to the power control switches
of the two traction machines).
superior). As shown in Figure 8-9. In the branch
box, open three cable outlet holes. The cables should be knotted in the outlet
holes to prevent the plug from falling off on its own. If the power supply
branch box is made of metal, it must be grounded and set at
a location convenient for connecting the two tractors. After use,
the power cord should be removed in time.
