A kind of servicing unit of interturn in stator windings Hi-pot Tester
Technical field:
The present invention relates to the technical field of stator Hi-pot Tester, more specifically to a kind of servicing unit of interturn in stator windings Hi-pot Tester.
Background technology:
Compressor is the core component in refrigeration system, and the stator of motor is the vitals that compressor is realized operation, existing stator after assembled formation, generally all require into performance test and voltage-withstand test.Described voltage-withstand test be mainly the coil that detects stator whether contact with iron core or distance too near, and coil contacts with iron core or apart from too closely there will be electric spark, easily causes the burning machine of compressor if do not processed the stator of above-mentioned state during voltage-withstand test.So unpassable voltage-withstand test can only judge that its position processes by electric spark, and in normal optical bright ring border, be difficult for finding that electric spark, the stator which causes can't pass voltage-withstand test cannot find solves position.
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.

Embodiment:
Embodiment: see shown in Fig. 1 to 4, a kind of servicing unit of interturn in stator windings Hi-pot Tester, the testing cassete 1 that comprises ' returning ' font, on one side of testing cassete 1 and upper surface, all form observation port 1a and be fixed with black glass, in testing cassete 1, be inserted with dual directional drawer box 2, described dual directional drawer box 2 comprises that the two ends of 21, two cross support arms 21 of two cross support arms are all fixed with shrouding 23, middle part is fixed with dividing plate 24, and the upper end of dividing plate 24 and shrouding 23 is fixed together by connecting link 28; On the medial surface of shrouding 23 upper ends, be all fixed with plug 27 and derby 26, plug 27 and derby 26 are electrically connected;
On the cross support arm 21 of described dividing plate 24 both sides, be all fixed with sheet metal 25, on the lower end of cross support arm 21, be fixed with guide rail 22, guide rail 22 upper sleeves are on linear bearing 11, linear bearing 11 is fixed in the inside bottom surface of testing cassete 1, in the inside bottom surface of described testing cassete 1, being fixed with some Universal casters 12, conflicts on sheet metal 25 in the upper end of Universal caster 12; On described testing cassete 1, form the power connection seat 13 of flute profile, power connection seat 13 is connected together with the extension line of Universal caster 12 respectively at Hi-pot Tester.
Described testing cassete 1, cross support arm 21 and shrouding 23 all adopt insulating material, are all fixed with square 29 on the lateral surface of shrouding 23.
Described shrouding 23 areas are greater than the xsect of place testing cassete 1 inner channel, and the width of described dividing plate 24 equals the width of testing cassete 1 inner channel, and the upper surface of the upper surface of dividing plate 24 and testing cassete 1 inner channel at grade.
The position of the derby 26 on described shrouding 23 is corresponding with the position of power connection seat 13 on testing cassete 1.
Principle of work: when the present invention uses, stator is put on the sheet metal 5 of dual directional drawer box 2, the lead terminal of stator is plugged on the plug 27 on shrouding 23, then twitching dual directional drawer box 2 makes the shrouding 23 of stator place side cover a side of testing cassete 1, make it to become a darkroom, and the derby 26 of shrouding 23 now contacts with power connection seat 13 on testing cassete 1, being equivalent to the coil of stator and iron core is electrically connected respectively at the lead-in wire of Hi-pot Tester, start Hi-pot Tester, from the observation port 1a of testing cassete 1, just can find those positions that only withstand voltage stator is fought, and this device can be placed stator while realizing pressure measurement, improved the speed of voltage-withstand test.
