Abstract
Description
Technical field
The invention discloses a kind of method of testing of electromagnetic wire, can detect at the electromagnetic wire of electromagnetic wire production industry to online production.
Background technology
The electrical insulation properties of electromagnetic wire is the key index weighing electromagnetic wire quality good or not, judges that electromagnetic wire electrical insulation properties quality needs to realize by carrying out proof voltage test to electromagnetic wire.The method of testing of known electromagnetic wire is: electromagnetic wire samples → enters detection case → energising and makes voltage-withstand test → testing result.The traditional detection method of this electromagnetic wire has following defect in actual applications: the mistake in electromagnetic wire is produced is painted, cured production technology section, because curing insufficient or excessively curing, remaining organic molecule solvent is had in the insulation course of electromagnetic wire, the organic molecule solvent of these remnants not easily comes out in a short time, just its defect need can be manifested through depositing, after unaccelerated aging 15 days-180 days (situation different time is different), the existence of organic molecule solvent can reduce the insulativity of electromagnetic wire, until can not use.But this organic molecule solvent that electromagnetic wire insulation course exists can bear the impact of high voltage after electromagnetic wire cures, be not easily detected when causing withstand voltage to its test, the invisible defect that electromagnetic wire exists can not be found; Along with the depositing of electromagnetic wire, unaccelerated aging, the organic molecule solvent of these remnants to external diffusion, so just weakens the dieletric strength of insulation course by insulation course, and at this time the electric durability of electromagnetic wire can be able to decline greatly, and what have even can not use.
Summary of the invention
Object of the present invention aims to provide a kind of method of testing of electromagnetic wire, utilize this method of testing immediately can carry out sampling and testing to the electromagnetic wire of online production, reach the invisible defect whether Timeliness coverage electromagnetic wire exists organic small molecule solvent, sampling on duty, on dutyly draw testing result, increase substantially electromagnetic wire detection efficiency, ensure electromagnetic wire Detection job.
Following technical scheme is taken for realizing object of the present invention:
A method of testing for electromagnetic wire, described detection method is: electromagnetic wire sampling → poach → dry → enter detection case → energising to make voltage-withstand test → testing result.
Described poach temperature is 95 DEG C ~ 100 DEG C.
The described poach time is 25 minutes ~ 35 minutes.
Described bake out temperature is 60 DEG C ~ 80 DEG C.
Described drying time is: 10 minutes ~ 15 minutes.
The present invention enters detection case after drying, voltage-withstand test is made in energising, finished product detection technique is identical with traditional characterization processes, does not repeat them here.
Specific implementation method is as follows:
Power taking magnet-wire sample, entering water temperature is carry out poach in 95 DEG C ~ 100 DEG C water, the poach time is 25 minutes ~ 35 minutes, then taking out and putting into temperature is that the drying chamber of 60 DEG C ~ 80 DEG C is dried, drying time is 10 minutes ~ 15 minutes, then enter detection case energising and make voltage-withstand test, after test, draw testing result.
Feature of the present invention is that method of testing is simple, convenient operation, easily realize; Its remarkable advantage can carry out instant sampling and testing to the electromagnetic wire of online production, namely sample after namely detection need not wait until unaccelerated aging 15-180 days and detect again, accelerate electromagnetic wire digestion time, whether Timeliness coverage electromagnetic wire exists the invisible defect of organic small molecule solvent, significantly improve the detection efficiency of electromagnetic wire, ensure the Detection job of electromagnetic wire.
Embodiment
Technical characteristic of the present invention is further described below in conjunction with embodiment:
Embodiment 1
Cut-off footpath is 0.1mm electromagnetic wire sample, and entering water temperature is carry out poach in the water of 95 DEG C, and the poach time is 25 minutes, then taking out and putting into temperature is that the drying chamber of 60 DEG C is dried, drying time is 10 minutes, then enters detection case energising and makes voltage-withstand test, take out after test.
Embodiment 2
Cut-off footpath is 0.15mm electromagnetic wire sample, and entering water temperature is carry out poach in the water of 100 DEG C, and the poach time is 30 minutes, then taking out and putting into temperature is that the drying chamber of 70 DEG C is dried, drying time is 13 minutes, then enters detection case energising and makes voltage-withstand test, take out after test.
Embodiment 3
Cut-off footpath is 0.25mm electromagnetic wire sample, and entering water temperature is carry out poach in the water of 100 DEG C, and the poach time is 35 minutes, then taking out and putting into temperature is that the drying chamber of 80 DEG C is dried, drying time is 15 minutes, then enters detection case energising and makes voltage-withstand test, take out after test.
Boil because the present invention first carries out sampling water to the electromagnetic wire of online production before entering detection case test, dry, accelerate aging, the digestion time that shortens electromagnetic wire of electromagnetic wire, the invisible defect of electromagnetic wire organic molecule solvent is come out in advance, adopt the rate of accuracy reached of this method test electromagnetic wire absolutely, practical reliable, convenient operation.
