Failure of low-voltage electric flat transfer cart

 

Low-voltage electric flat cars are widely used, so the frequency of failures is also very high. Electric flat transfer cars are prone to three kinds of failures. The following introduces the fault description of low-voltage electric flat transfer cart:

1.No electricity. Whether the power system is sending power to the power supply of the electric flat transfer cart, generally use a test pencil to test, if there is no power, wait until the power is sent to work.

2. The voltage is too low. The terminal voltage of the electric flat transfer cart is more than 10% lower than the rated voltage, and the starting torque of the low-voltage electric flat transfer cart is too small, and the electric flat transfer cart cannot move and cannot work normally. During inspection, use a multimeter or voltmeter to measure the voltage at the input terminal of the electric flat transfer cart.

3. Automatic parking. Electric flat cars have an automatic protection function. If the voltage fluctuation of the enterprise is relatively large, the protection device will cut off the power supply of the car to protect the main board of the low-voltage electric flat transfer cart.
