Fig. 3 is a test flow chart of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiments of the present invention relate to a kind of Hi-pot test equipment, as shown in Figure 1, comprise engineering machine, high pressure instrument, test fixture, electric appliance control box and device for dotting; Described high pressure instrument links to each other with described test fixture by described electric appliance control box, the product clamping is on test fixture, described high pressure instrument is used for output HIGH voltage, described test fixture links to each other with described engineering machine by electric appliance control box, by described engineering calculation machine control signal product is applied high pressure, whether and it is qualified to carry out the analysis and judgement product by the electric current that test fixture records, if qualified, is then made marks on product by device for dotting; As if defective, find out the trouble spot of bad product.Wherein, have high tension protection circuit in the described high pressure instrument, and have the pointwise test function; Described electric appliance control box has sudden-stop function.
Fig. 2 is the high tension protection circuit structural representation; described high tension protection circuit is made up of diode, comparer and logical circuit; the positive pole of described diode is connected with the secondary low side of transformer in the described high pressure instrument; negative pole links to each other with an input end of described comparer; another input end of described comparer links to each other with reference voltage; the output terminal of described comparer links to each other with logical circuit, and the output terminal of logical circuit links to each other with the relay of control high pressure instrument output terminal.When testing, the secondary low side of the transformer in the high pressure instrument produces voltage, is added to the negative input end of comparer IC through diode D, and under the normal condition, the voltage of the negative input end of comparer IC is less than the positive input terminal of comparer IC, and comparer IC does not overturn.If test product is when puncturing; the voltage of the secondary low side of the transformer in the high pressure instrument can raise rapidly; the voltage of the negative input end of comparer IC can be greater than the positive input terminal of comparer IC at this moment; comparer IC upset; through logical circuit; make the relay of control high pressure instrument output terminal disconnect, play the better protect effect, can utilize reset function to get back to normal condition after fixing a breakdown.
The idiographic flow of test products of the present invention as shown in Figure 3.At first, product to be measured is installed on the test fixture.Secondly, press start button, high pressure instrument output voltage values, this magnitude of voltage can be provided with according to product to be measured, and generally speaking, this voltage is that the operating voltage of product twice to be measured adds 1000 volts.Then, whether the electric current that is recorded between two circuits of product by test fixture is also judged being communicated with between two end points of a circuit simultaneously.Then, engineering machine receives the electric current that test fixture records, and the electric current that records is analyzed by its inner software, judge whether this electric current surpasses the threshold value that sets in advance, if the electric current that records does not have to surpass when not disconnecting between the threshold value set in advance and the product the same line road, then send signal to device for dotting, device for dotting makes marks on product after receiving signal, represent that this product is specification product, so that distinguish with the product that did not carry out test; If the electric current that records surpasses the threshold value that sets in advance; perhaps the same line road disconnects; represent that then this product is defective; high pressure instrument testing software tests (multiple spot is tested simultaneously) by network technique originally and is converted to pointwise test at this moment; find out the circuit that is short-circuited or opens circuit by circuit ground test of a circuit; be presented at the testing software interface; can open-and-shutly just know that circuit has problem to be convenient to the later stage fault analysis; searching is gone wrong behind the circuit; the equipment protection circuit can cut off output voltage, to guarantee the safety of operating personnel and machine.If the holding circuit in the high pressure instrument was not cut off output voltage owing to lose efficacy, operating personnel can come the output voltage of cutoff high instrument by the scram button of pressing electric appliance control box.
