Investigation of frequent tripping of leakage protector of cow milking machine?
The main component of the Electric Control Box of the cow milking machine is a total power leakage protector QF, which plays a good role in the safe use of the equipment.
However, frequent tripping may occur in actual use. What is the cause? How to troubleshoot?
The frequent tripping of the leakage protector is due to the leakage phenomenon caused by the humid environment of the cow milking machine or the rodent damage and improper maintenance of the customer.
The elimination method can be used to check, cut off the overload protector QF of all pumps, connect only one pump at a time for continuous operation, detect whether the leakage protector is affected, and find out a group of circuits with problems.
Give priority to check whether the insulation of the power supply line from the terminal of the Electric Control Box to the pump body is damaged and whether the node is affected with damp. If there is water near the milk pump, it may also enter the motor and cause short circuit of the winding, if this fault occurs during debugging, check whether the connection is repeated or whether the power supply is missing.
The frequent tripping of the leakage protector of the cow milking machine will not only affect the milking efficiency, but also cause certain damage to the milking equipment, therefore, problems found in use must be checked and solved in time.
