TH9010 series of Tonghui multi-channel withstand voltage testerOverview

The TH9010 series is a multi-channel parallel scanning voltage tester developed by Tonghui Electronics based on years of experience in developing electrical safety testing instruments. A single machine can simultaneously measure 8 channels and judge the test results according to each channel, which is equivalent to eight TH9310 working simultaneously. This not only improves the testing efficiency of the production line, but also saves production line space. At the same time, this instrument can be extended to 8 × 16 channels by connecting a scanner to meet the actual needs of customers.

Synchronous testing function

The TH9010 series supports synchronous parallel output with 8 independent channels, thereby increasing testing efficiency by 8 times. Paired with the dedicated scanning extender TH90101, one channel can be expanded to 4 channels. By adding an additional 4 extenders, the instrument can be expanded to 128 channels (8 * 4 * 4=128 channels).

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.

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.
