No matter what mechanical automation equipment, short circuit is one of the more serious faults, which not only affects the normal work, but also produces certain damage to the machine, so if the short circuit phenomenon is found, the power should be turned off immediately, and then checked and repaired until the fault is removed before production.

A. The main causes of short circuits in automatic winding machines include.

1. the circuit being disconnected during maintenance; problems in the manufacturing process.

2. poor welding, overheating and desoldering of the threaded end of each component.

3. damage by external forces.

4. short circuit and grounding, resulting in combustion, etc.

Second, automatic winding machine short circuit detection method

1. Multimeter or shake table detection method. Measure the beginning and end of each phase separately, the infinity of a phase is the short-circuit phase.

2. Observation method. The common location of the break point is usually at the end, and can be found by visual inspection of both ends to see if the ends are loose.

3. Power on detection method. When the motor is running normally, use a clamp-on ammeter to measure the three-phase current. If the three-phase current is unbalanced and can eliminate the short-circuit fault, a short-circuit fault will occur with a small current.

Third, the automatic winding machine short circuit handling and repair methods

1. The internal circuit of the automatic winding machine, this situation generally can not be repaired, the coil must be replaced.

2. When the circuit breaker is located at the end, please weld it firmly from the head after connection, wrap it with appropriate insulating material and wet it with insulating paint to make it dry, and then cover it with insulating sleeve.

These are the causes and solutions of automatic winding machine short circuit, note that when there is a short circuit, do not panic, they do not know how to deal with the situation, turn off the power, promptly report to a superior or maintenance personnel to determine the cause and solve the problem!
