Talk about winding machine break should how to deal with
(1) Causes
The main reasons for winding machine break include: the line is torn off during maintenance; Manufacturing process problems; The wire ends of winding machine components are not well welded, overheating and welding; Winding machine is damaged by external forces; Winding machine short circuit and grounding, resulting in burning.
(2) Detection methods
1 Observation method. Breakpoints often occur in the position of the winding machine, winding machine manufacturers can find the two ends of the winding machine through visual inspection without welding.
2 Multimeter or shaking meter detection method. Measure the head and tail of each phase winding machine respectively, and the infinite phase is the open phase.
3 Power detection method. When the motor is in normal operation, the clamp ammeter is used to measure the three-phase current. If the three-phase current is unbalanced and the short-circuit fault can be eliminated, the winding machine with small current has the fault of circuit break.
(iii) Treatment of repair methods
1 when the break is at the end, weld firmly from the head after connection, wrap with proper insulation and dip in insulating paint to dry, and cover with insulating sleeve to use.
2 The internal winding machine is broken, this kind of condition generally cannot be repaired, must replace winding machine coil.
