What to do if there is a short circuit in the winding machine

The winding machine is a very important equipment in the mass production and processing of coils. It has various advantages such as active wiring/counting, efficient processing, and convenient use, and is widely used in production and processing of transformer coils, motor coils, and other products. Open circuit in the winding machine is one of the common faults of the winding machine. If a circuit is found, the winding machine needs to be stopped immediately and then tested and repaired. Let's talk about the manufacturer of the winding machine and how to handle the circuit breaker of the winding machine.

Let's first take a look at what a winding machine circuit is and what its impact is. When a wire breakage problem is found in the winding machine, it is called an open circuit in the winding machine, which is a condition of internal phase loss in the motor. When there is a circuit break in the winding machine, the motor may exhibit a series of problems, ranging from difficulty in starting, unbalanced three-phase current, abnormal vibration, severe temperature rise beyond the controllable range, smoke from the winding machine, and burning.

1、 Cause of occurrence

The main reasons for the circuit breaker of the winding machine include: the circuit was torn during maintenance; Manufacturing process issues; Poor welding of the wire heads of various components of the winding machine, overheating and desoldering; The winding machine is damaged by external force; Short circuit and grounding of the winding machine, resulting in burning, etc.

2、 Testing method

1. Observation method. The breakpoint is usually located at the end of the winding machine, and it can be visually checked to see if there is any desoldering at the two ends of the winding machine.

2. Multimeter or tramegger detection method. At the beginning and end of each phase winding machine, the infinite phase is the open circuit phase.

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

3、 Handling repair methods

When the circuit breaker is at the end, after connecting it, weld it firmly from the beginning, wrap it with appropriate insulation and dry it with insulating paint, and then cover it with an insulating sleeve for use.

2. The internal winding machine has an open circuit, which is generally irreparable. It is necessary to replace the winding machine coil.
