Abstract
A DC voltage-resist tester of the utility model is an electric meter for testing the DC voltage-resist value of electronic components and other electrical elements. The DC voltage-resist testing of the electronic components and other electrical elements still needs an expensive and heavy voltage-resist testing machine or an oscillograph at present, while the large quantities of township enterprises, individual electronic component shops and repair shops which spring up at present often have no condition of being provided with the voltage-resist testing machine or the oscillograph. The utility model provides a tester for testing the DC voltage-resist value of the electronic components and other electrical elements, the appearance of the tester is similar to an ordinary small-size universal meter and the cost of the tester is low.
Description
The utility model relates to a kind of ammeter, particularly has the direct current proof voltage test chart of testing electronic element and other electric elements direct current proof voltage numerical value function.
Existing ammeter generally is made up of shell, gauge outfit and switch etc., only uses as electric weight such as measuring voltage, electric current, power.The direct current proof voltage test of electronic component and other electric elements will be used heavy, expensive and withstand voltage test machine or oscillograph that need be connected with electric network source.The test of withstand voltage test machine is destructive test, and oscillographic test then can only be extrapolated about proof voltage numerical value of tested element according to image.
The purpose of this utility model aims to provide a kind of direct current proof voltage test chart that tested element can accurately test out its voltage breakdown numerical value and cheapness, exquisiteness again that neither can destroy.This direct current proof voltage test chart is particularly suitable for the usefulness of the direct current withstand voltage properties of township and village enterprises, individual electronic component shop and repair shop's testing electronic element and other electric elements.
The utility model can be implemented by following mode.
In the housing of similar general ammeter, the semiconductor high pressure generator of packing into, the output terminal of this high pressure generator is attempted by two test leads of this table and shows that high pressure generator is powered by button switch by the dry cell or the rectifier that are contained in the watchcase on the voltmeter head of proof voltage numerical value.During use, earlier with tested element two termination test lead two ends, the switch that presses button then, the shown magnitude of voltage of voltmeter head this moment is the direct current proof voltage numerical value of this tested element.
Below in conjunction with embodiment the utility model is further described.
Accompanying drawing is an electrical principle synoptic diagram of the present utility model.Direct supply among the figure (1) provides electric energy for semiconductor high pressure generator (3) by button switch (2), and the output terminal of semiconductor high pressure generator (3) is in parallel with capacitor (4), voltmeter head (5) and test lead ab.Direct supply (1) can be a dry cell, also can be rectifier, or the combination of dry cell and rectifier, makes AC/DC.Semiconductor high pressure generator (3) can be any oscillistor, is the constant current source of a high internal resistance, and the regulating element parameter makes its electric current output constant between 1.5～2 milliamperes.Voltmeter head (5) can be pointer-type also can be digital.
Claims (1)
1., interior dress semiconductor high pressure generator (3) a direct current proof voltage test chart of being made up of direct supply (1), pushbutton switch (2) and voltmeter head parts such as (5) is characterized in that:; 2., the output terminal of semiconductor high pressure generator (3) and capacitor (4) and voltmeter head (5) and test lead ab are in parallel.
