How to deal with short-circuit situation in winding machine

A broken circuit is one of the common problems of winding machine, and the machine needs to be stopped immediately and then tested and repaired. Dongguan vertical and horizontal mechanical winding machine manufacturers to say, winding machine breakage how to deal with.

First of all, let’s first look at what is the winding machine broken circuit, it has what impact. When the winding machine is found in the broken wire fault is called winding machine break, which is the condition of the motor internal lack of phase. When the winding machine is broken, the motor will present a series of problems, the light will be difficult to start moving, three-phase current imbalance, abnormal vibration, serious temperature rise beyond the controllable range, the winding machine smoke, scorching and other imaginary.

 

(A) the cause of occurrence

 

The main reason for the occurrence of winding machine disconnection contains, the line is ripped off during maintenance; manufacturing process problems; winding machine components wire head welding is poor, overheating desoldering; winding machine is damaged by external forces; winding machine short circuit and grounding, resulting in incineration, etc.

 

(II) detection methods

 

1, observation method. The most common location of the breakpoint is generally in the end of the winding machine parts, can be found by visual inspection of the two ends of the winding machine with or without desoldering.

 

2, multimeter or shaking table detection method. Separate measurement of each phase of the first and last end of the winding machine, infinity of a phase for the broken phase.

 

3, the power-on detection method. In the normal operation of the motor, respectively, using the clamp current meter to measure the three-phase current, if the three-phase current imbalance, and can be ruled out to short-circuit problems, the minimum current winding machine has a breakage problem.

 

(C) to deal with the repair method

 

1. break in the end, connected to weld from scratch, wrapped with appropriate insulation and dip insulation paint drying, set of insulating sleeves can be used.

 

2. Internal winding machine break, this condition is generally not repair, it is necessary to replace the winding machine coil.
