Transformer coil winding machine is a very important winding machine in mass production processing of coils. It has the advantages of active wire arrangement/counting. Easy to use and other advantages, it will be used for transformer coils, motor coils and other production processing. Short circuit is one of the common problems of winding machine, transformer coil winding machine found short circuit needs to be stopped immediately, then tested and repaired. Wirewinding machine manufacturer, how to deal with short circuit in wirewinding machine.

Let’s take a look at what a short circuit in a transformer coil winding machine is and what its effects are. When a short circuit is found in a winding machine, it is called a short circuit in the winding machine, which is a condition of insufficient phase inside the motor. When the winding machine is short-circuited, the motor will have a series of problems, starting difficulties, three-phase current imbalance, abnormal vibration, temperature rise seriously beyond the controllable range. The winding machine smoke. Scorching and other imaginary.

I. The cause of occurrence

Transformer coil winding machine short-circuit causes mainly include wire breakage in the maintenance process; manufacturing process problems; winding machine components poor welding, overheating desoldering; winding machine external damage; winding machine short-circuit grounding, resulting in combustion, etc.

II. Detection methods

1. Observation method. Break point is often presented in the location of the end of the winding machine, you can visually check whether the ends of the winding machine desoldering.

2. Multimeter or shaking table detection method. Separate measurement of the head and tail end of each phase of the winding machine, infinite phase for the short-circuit phase.

3. Power-on detection method. When the motor is running normally, use the clamp-on ammeter to measure the three-phase current. If the three-phase current is unbalanced, the short-circuit problem can be eliminated, then the small-current winding machine has a short-circuit problem.

III. Handling repair method

1. When the short circuit is at the end, connect it and weld it firmly from the beginning, wrap it with proper insulation and soak it with insulating paint to dry, and set it with insulating sleeve to use.

2. Internal winding machine short-circuit, this situation generally can not be repaired, the need to replace the winding machine coil.
