What happens when a toroidal coil inductor winding machine breaks a loop?

Toroidal coil inductor winding machine breakage is one of the common failures of toroidal coil inductor winding machine. Ring winding machine breakage requires immediate shutdown, followed by inspection and maintenance. The following is how to deal with a broken ring winder.

First, let’s look at what happens when a toroidal coil inductor winding machine breaks and what the effects are. When a toroidal coil inductor winding machine breaks, this is the internal phase of the motor. When the ring winder is broken, the motor will have a series of failures, lighting starting difficulties, three-phase current imbalance, abnormal vibration, temperature rise beyond the controllable range, smoke from the ring winder. Burning, etc.

(1) Cause

The main reasons for ring winding machine breakage are: line breakage during maintenance; problems in the manufacturing process; improper welding of the wire head of the winding machine components, welding overheating; external damage to the winding machine; winding machine short circuit and grounding, resulting in combustion and damage.

(2) Detection methods

1. observation method. both ends of the Z-ring winder can be visually inspected to find the location of common break points.

2. Multimeter or vibration meter detection method. Measure the head and tail of each phase of the loop winder separately, and the infinite phase is the open phase.

3. Power detection method. When the motor is running normally, the automatic winding machine measures the three-phase current with a fixture ammeter. If the three-phase current is unbalanced, the short-circuit fault can be eliminated. The current Z of the winding machine has a small circuit breaker.

(3) processing repair method

1. When the end of the line is disconnected, connect and weld firmly, wrap with appropriate insulating material, soak and dry with insulating paint, and cover with insulating sleeves.

2. Transformer ring winding machine internal ring winding machine damage, generally can not be repaired. Replace the ring winder coil.
