Abstract
This patent discloses a kind of medium-sized low voltage motor and wraps detection novel clamp in vain, belongs to electric machines test technical field, including test section, clamping device and main part, it is important to：The part of detecting is based on direct-flow double bridge principle and is designed using bilateral insulating blanked clamper, test D.C. resistance can be effectively eliminated in detection process, make D.C. resistance test degree of unbalancedness and original 3% is reduced to 0.3%, motor manufacturing level and welding quality can be effectively improved, is of great significance to a motor quality of production control.
Description
Technical field
The invention belongs to electric machines test technical field, is related to a kind of low voltage motor and wraps detection fixture in vain.
Background technology
It is that an important detection means of motor performance index, traditional test are weighed in motor production that motor wraps detection in vain
Directly it is connected for metal holder with the white bag lead of motor and cuts that clip model is single cannot to be adapted to Multiple Type electromechanical testing requirement.It is special
It is not that low-voltage high-power motor is high to direct current generator test request, it is desirable to realize that (turn-to-turn is pressure-resistant, power frequency for white bag detection integration
Pressure-resistant, D.C. resistance, rotating excitation field direction, three-phase balance) test.This fixture can meet above project integrated testing
It is required that improving the white bag testing efficiency of motor and accuracy, it is of great significance to the lifting of the motor quality of production.
The content of the invention
The present invention predominantly overcomes in the white bag detection process of conventional motor D.C. resistance contact resistance excessive and pressure-resistant experiment,
Turn-to-turn tests high-tension safety issue, devises a kind of detection fixture, changes existing test mode and present situation, based on direct current
Double bridge principle, part of detecting use bilateral insulating blanked clamper design agents part to improve direct current for high-strength insulating material
Resistance measuring accuracy meets the security of voltage tester again.
The technical solution adopted by the present invention is：Medium-sized voltage motor wraps detection novel clamp, including part of detecting, clamping in vain
Mechanism, main body.
Whole part of detecting material is copper material, and p-wire A and p-wire B high-current test lines are respectively arranged in test block
Below mounting base and guide groove is designed with, p-wire will not be cut off because of the activity of test block；Part of detecting is based on direct current both arms
Electrical bridge principle, is designed using bilateral insulating blanked clamper, and two test blocks are that be not in contact with before lead will not clamping or not clamping test
Redundant contacts resistance is produced, is contacted at the same time with motor down-lead in detection D.C. resistance and clamps to effectively eliminate and detect clip in the past
Contact resistance during test, can Validity Test go out the precise dc resistance of winding, winding resistance unbalance degree fault diagnosis is carried
For authoritative foundation.It is 3.352X10 to average contact resistance after its short-circuit test this clamp through Estimate of Resistance for DC Low Resistance tester-9
This resistance of Ω influences minimum negligible in the medium-sized D.C. resistance test result on low voltage motor.
Clamp system uses elbow formula fixture, and dead point design, does not rebound after clamping, is clamped to adapt to different size electromechanical testing
Contiguous block be elastic high-strength rubber, test copper billet tail end design and can replace at any time for dovetail groove, it is easy to operate.
The main testing requirement for putting forward structure and meeting highest motor 6KV for high-strength insulation structure, improves Security of test.This hair
Bright beneficial effect is：Motor wraps traditional test mode in detection and can only measure motor DC resistance test degree of unbalancedness in vain
3% or so, tested person condition influences to need this more test could be qualified, uneven using the test D.C. resistance test of this fixture
Weighing apparatus degree is can be controlled within 0.3%, is controlled the motor quality of production and is improved product quality and be of great significance；Since main body is
Insulating Design can improve the security of test process.
Brief description of the drawings
Fig. 1 is structure chart of the present invention：1 represents insulating body, and 2 represent elbow formula fixture, and 3 represent adjustable bolt, and 4 represent bullet
Property rubber block, 5 represent detachable copper billet, and 6 represent testing current line and test formula line B mounting bases, 7 deputy activity test blocks and survey
Line A mounting bases are tried, 8 represent test guide groove, and 9 represent elbow formula fixture fixing bolt, and 10 represent elbow formula fixture connection metal derby.
Embodiment
Present invention elbow formula fixture driving test block in motor wraps test in vain clamps lead, then carries out integrated (turn-to-turn
Pressure-resistant, industrial frequency withstand voltage, D.C. resistance, rotating excitation field direction, three-phase balance) test, resetted after being completed.
