500VA/200VA (TH9520A) digital high-power withstand voltage test

Compared with the principle of analog safety testing, digital withstand voltage testing outputs high voltage that is not affected by market noise, greatly improving voltage quality. At the same time, it can digitally display real-time test voltage, achieving more accurate measurement and display. And the output voltage adopts adaptive feedback control, so that changes in the output load will not cause changes in the output voltage.

Electric shock protection function

When the operator comes into contact with the high-voltage output terminal, the instrument will monitor whether the current flowing through the human body is too high. If it is determined to be an electric shock, the instrument will immediately cut off the output to ensure the user's safety.

Open short circuit detection function (OSC)

During the withstand voltage test, open circuits may occur due to contact between the tested component and the test line, or damage to the test line, leading to a misjudgment of the product as good; The test line is short circuited due to damage to the tested component or a small distance between the tested ends. By using OCS function, TH9520/A can detect the short circuit situation at the test end in advance, reduce the occurrence of contact problems on the production line, protect the fixture equipment, and save testing costs.

Arc Detection Function (ARC)

Voltage withstand * * refers to the occurrence of electrical flashover or insulation damage during voltage withstand testing. Nowadays, withstand voltage insulation testing has become a standard equipment for testing various electrical equipment and insulation materials. However, considering only insulation failure cannot completely solve the product's * * problem. Another phenomenon, arc discharge ARC, is receiving increasing attention in withstand voltage testing. There is a high correlation between discharge and insulation ability, so ARC detection is the key to controlling product quality.

There are two situations where arc discharge occurs:

a) When a material is subjected to high voltage and the electric field strength is greater than the ionization energy of the gas, it will cause instantaneous ionization of the gas on the surface of the material, resulting in ignition and temperature rise on the material surface. Long term ignition and temperature rise may cause material quality changes, leading to insulation degradation and a decrease in voltage tolerance, ultimately resulting in insulation failure.

b) When the distance between the detection points of the test piece is too small, applying a high voltage at both ends of the test piece will ionize the air in the space between the two ends of the detection point, forming a sparking phenomenon, that is, the arc pulling phenomenon. The phenomenon of arcing generates high-frequency instantaneous discharge, which produces a high-frequency current signal during the testing process as shown in Figure D. The arc detection (ARC) function uses high-frequency electricity measurement to detect and determine whether the insulation performance of the material is good.

Coil pulse testing function

This tester can effectively and non destructively perform high-voltage pulse testing on coil windings to test their electrical performance. The principle is to apply the same pulse voltage to the tested coil winding and the standard coil winding, compare their transient waveforms, and determine the quality of the tested winding component. Transient waveform refers to the attenuated oscillation waveform that occurs within a coil. It can simultaneously determine the inductance, quality factor Q value, number of turns difference, and interlayer short circuit of the winding. More specifically, in the presence of magnetic materials, it can also determine the difference in material; The occurrence of corona discharge under high voltage pulses can also be used to determine the insulation between winding layers or multiple windings.
