Utility model content

The technical problems to be solved in the utility model be to provide a kind of simple in structure, easy to operate, detection efficiency is high, can directly show the transformer testing device of all testing results.

For addressing the above problem, the utility model provides a kind of novel transformer test suite, comprise frame and be fixed on the base on this framework soleplate, the top of described base is connected with one for placing the back up pad of described transformer by flexible member, described back up pad top is also provided with one and drives the lifter plate of lifting by propulsion system, it is characterized in that, in described back up pad, be also provided with some through holes that stretch into for holding the stitch of described transformer, the upper surface of described base is provided with some the first probes that are positioned under described through hole, on described lifter plate, be also provided with some for testing the second probe of magnetic core of transformer, described the first probe and the second probe are all connected to one by wire and can test on the tester of a plurality of parameters, described tester one end is also connected on some display screens, described in each, display screen at least can show a test data.

As further improvement of the utility model, described in each, display screen is all connected with a mini-printer.

As further improvement of the utility model, on described base, being also provided with at least one can be through the guide pole of described back up pad, and described back up pad can be slided on described guide pole.

As further improvement of the utility model, described guide pole is two.

As further improvement of the utility model, described flexible member is spring, and it is placed on described guide pole and one end is fixedly connected with described back up pad, and the other end is resisted against or is fixedly connected on described base.

As further improvement of the utility model, described propulsion system are speed wrench.

As further improvement of the utility model, described tester at least can be tested one or more in following parameter: conduction, direct current resistance, series inductance, shunt inductance, interelectrode capacity, series capacitance, shunt capacitance, electric capacity D value, inductance coupling, leakage inductance, number of turns ratio, insulation resistance, impedance.

As further improvement of the utility model, described display screen, by a holder, is connected in described frame.

The beneficial effects of the utility model are, tester is visited and is connected with stitch, the magnetic core of transformer respectively by the first probe and second, transformer is tested, obtain some parameters of this transformer, and by a plurality of display screens, these parameters are shown respectively, each display screen only shows on a small quantity, even a parameter.Which can be intuitive, clear the result of acquisition test.Problems of the prior art have been solved.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details.

As illustrated in fig. 1 and 2, the utility model comprises frame 4 and is fixed on the base 16 on the base plate 8 of this frame 4, the top of base 16 is connected with one for placing the back up pad 20 of transformer by flexible member, on base 16, being also provided with two can be through the guide pole 12 of back up pad 20, back up pad 20 can be slided on guide pole 12, this guide pole 12 play the guiding role while sliding up and down for back up pad 20, this flexible member adopts spring 14 conventionally, spring 14 is enclosed within on guide pole 12, its one end is fixedly connected with back up pad 20, the other end against or be fixedly connected on base 16, the effect that spring 14 is set here not only can be played the effect of buffering when back up pad 20 pressurized, and after removing, back up pad 20 pressure can drive back up pad 20 upwards to reset, back up pad 20 tops are also provided with one and drive the lifter plate 26 of lifting by propulsion system, these propulsion system are speed wrench 28 simple to operation preferably, in back up pad 20, be also provided with some through holes 22 that stretch into for holding the stitch of transformer, the upper surface of base 16 is provided with some the first probes 18 that are positioned under through hole 22, on lifter plate 26, be also provided with some for testing the second probe 24 of magnetic core of transformer, the first probe 18 and the second probe 24 are all connected to one by wire 2 and can test on the tester of a plurality of parameters, this tester can be tested many kinds of parameters, for example: conduction, direct current resistance, series inductance, shunt inductance, interelectrode capacity, series capacitance, shunt capacitance, electric capacity D value, inductance coupling, leakage inductance, number of turns ratio, insulation resistance, impedance etc., this tester one end is also connected on some display screens 10, this display screen 10 is all connected on a fixed mount 6 being fixed in frame 4.Each display screen 10 at least can show a test data.

During work, transformer to be measured is placed in back up pad 20, the stitch of this transformer extend in this through hole 22, then by propulsion system, drive lifter plate 26 to decline, when the second probe 24 of lifter plate 26 belows touches transformer, promoting back up pad 20 moves downward, contact with the stitch in through hole 22 to the first probe 18 on base 16, now, tester is visited respectively the stitch with transformer by the first probe 18 and second, magnetic core connects, transformer is tested, obtain some parameters of this transformer, and by a plurality of display screens 10, these parameters are shown respectively, 10 of each display screens show a small amount of, a parameter even.In addition, equal cocoa one mini-printer of each display screen 10 connects, and is convenient to direct printing test result.Which can be intuitive, clear the result of acquisition test.Problems of the prior art have been solved.

Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify and all should be equivalent substitute mode, within being included in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
