2、Basic testing items and inspection purposes
Serial Number |
Inspection items |
Detection method |
Inspection purpose |
1 |
Welding resistance |
Measurement of the DC resistance value of the welding point between the switching piece and the winding |
Assess welding quality, identify defective products, and locate false weld points |
2 |
Inter-room resistance |
Check the DC resistance value of the coils between adjacent slip rings. |
It can be found that there are inter-turn short circuits, broken wires,脱钩, hook direction errors, number of turns differences, short circuits between commutator plates, etc. |
3 |
Inter-room resistance |
Measure the DC resistance of the coil between the two commutator segments across 180 degrees. |
Able to verify whether the project indicators meet process requirements, and to detect inter-turn short circuits of the winding wire between different coil units. |
4 |
Insulation resistance |
Apply a certain DC voltage between the coil winding and the iron core (shaft), and measure its insulation resistance. |
Check whether the coil has leakage or short circuit with the iron core (shaft) |
5 |
Power frequency withstand voltage |
Applying a certain value of power frequency AC voltage between the coil winding and the iron core (shaft) and other parts, for a certain period of time, to test its AC dielectric strength |
Check the dielectric strength of the coil against the iron core (shaft) for power frequency voltage to detect any short circuit, breakdown, or arcing. |
6 |
Inter-turn withstand voltage |
Apply an impact voltage of a certain amplitude, according to the specified waveform requirements, between adjacent (or non-adjacent) two-commutating plates. |
Check for insulation defects, air gap discharge, or short circuits between coil turns (wires), between commutator segments for insulation issues or short circuits, and also inspect for deviations in winding turns, partial reverse embedding. |
7 |
Hook direction |
Fuzzy recognition technology |
Check the hook along the circumference of the commutator, and alarm if the hook direction is incorrect. |
