Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and a kind of servicing unit of interturn in stator windings Hi-pot Tester is provided, and it can find to can't pass the position of fighting of the stator of voltage-withstand test quickly and easily, has improved the efficiency of voltage-withstand test operation.
Technology solution of the present invention is as follows:
A kind of servicing unit of interturn in stator windings Hi-pot Tester, the testing cassete that comprises ' returning ' font, on one side of testing cassete and upper surface, all form observation port and be fixed with black glass, in testing cassete, be inserted with dual directional drawer box, described dual directional drawer box comprises two cross support arms, the two ends of two cross support arms are all fixed with shrouding, middle part is fixed with dividing plate, and the upper end of dividing plate and shrouding is fixed together by connecting link; On the medial surface of shrouding upper end, be all fixed with plug and derby, plug and derby are electrically connected;
On the cross support arm of described dividing plate both sides, be all fixed with sheet metal, on the lower end of cross support arm, be fixed with guide rail, guide rail upper sleeve is on linear bearing, linear bearing is fixed in the inside bottom surface of testing cassete, in the inside bottom surface of described testing cassete, being fixed with some Universal casters, conflicts on sheet metal in the upper end of Universal caster; On described testing cassete, form the power connection seat of flute profile, power connection seat and Universal caster are connected together respectively at the extension line of Hi-pot Tester.
Described testing cassete, cross support arm and shrouding all adopt insulating material, are all fixed with square on the lateral surface of shrouding.
Described shrouding area is greater than the xsect of place testing cassete inner channel, and the width of described dividing plate equals the width of testing cassete inner channel, and the upper surface of the upper surface of dividing plate and testing cassete inner channel at grade.
The position of the derby on described shrouding is corresponding with the position of power connection seat on testing cassete.
Beneficial effect of the present invention is:
It as for having facilitated discovery to can't pass the position of fighting of the stator of voltage-withstand test in dark surrounds, can pass through voltage-withstand test thereby process rear this type of stator of assurance by stator, has accelerated the speed of voltage-withstand test operation, has improved the production efficiency of stator.
