What to do if there is a short circuit in the automatic toroidal core coil inductor winding machine

Toroidal winding machine is a very important winding machine equipment in mass production processing of coils. It has the advantages of source wiring/counting, high processing efficiency and ease of use. It is used for the production processing of transformer coils and motor coils. Circuit breaker is one of the common failures of the toroidal winding machine. When a circuit breaker is found, the toroidal winding machine needs to be stopped immediately for inspection and maintenance. Let’s talk about how to deal with an open circuit in a toroidal winding machine.

Let’s take a look at what a winder is and what its effects are. When a broken wire fault is found in a ring winder, it is called a ring winder open circuit, which means the motor is out of phase. When a loop winder is turned on, the motor will have a number of problems. At least starting difficulties, three-phase current imbalance, abnormal vibration, temperature rise is seriously beyond the controllable range, ring winding machine smoke carbonization.

A cause.

Ring winding machine disconnection is mainly due to: maintenance process disconnection; manufacturing process problems; poor welding, overheating, desoldering of various parts of the ring winding machine; ring winding machine external damage; ring winding machine short-circuit grounding, resulting in combustion.

Second, the detection method.

1. Observation method. The break point is usually located at the end of the winding machine. You can visually find out whether there is desoldering at both ends of the winding machine.

2. Multimeter or megohmmeter detection method. Separate the head and tail of each phase of the ring winder, and the infinitely large phase is the broken phase.

3. Power-on detection method. In the normal operation of the motor, a clamp-on ammeter should be used to measure the three-phase current separately. If the three-phase current is unbalanced, the short-circuit problem can be eliminated, and the machine around the small current will break.

Third, the treatment and repair methods.

1. The end of the circuit breaker, welded firmly from the beginning, wrapped with appropriate insulation material, soaked and dried with insulating paint, and then put on the insulating sleeve.

2. The inner wraparound wire is broken, and generally cannot be repaired. Need to replace the wrap-around coil.
