Insulation line automatic winding machine in the event of a breakage and solutions
 
When the insulation wire automatic winding machine in the case of wire breakage fault is called winding machine circuit, which is the lack of internal phase motor. Appeared winding machine, the motor will be a series of failures, ranging from start-up difficulties, three-phase current imbalance, abnormal vibration, heavy temperature appears beyond the controllable range, winding machine smoke, scorch, etc. .

(A) the reasons for the reasons winding machine circuit breakers mainly include the reasons, the line was tampered with maintenance; manufacturing process problems; Winder various components thread bad welding, over-heat desoldering; Winder by external forces are damaged; Winder Short circuit and ground, resulting in burning and so on.
 
(B) test methods
1. Observation method. The most common location of the breakpoint is usually at the end of the winding machine, you can visually find the two ends of the winding machine with or without desoldering.
2. Multimeter or shake table detection method. Separately measured each phase winder end and end, an infinite phase for the open phase.
3 power detection method. In the normal operation of the motor, respectively, the use of clamp ammeter measuring three-phase current, if the three-phase current imbalance, and can eliminate the short-circuit fault, the minimum current winding machine has a circuit fault.
 
(C) deal with the repair method
1. Open circuit at the end, re-welded after the connection is good, wrapped with appropriate insulation and insulating paint drying, set the insulating sleeve can be used.
2. Internal winding machine circuit, this situation generally can not be repaired, you must replace the winding machine coil.
