Voltage breakdown tester, high voltage withstand tester, power frequency breakdown strength tester

Switching between AC and DC tests: 1. The high voltage output of this instrument is AC voltage. The method of obtaining direct current is to string a high-voltage silicon stack into the original circuit, making the test circuit a pulsating direct current voltage. The implementation process is that the silicon stack is already in the high-voltage insulation tower of the high-voltage transformer, and a short-circuit rod is usually used to short-circuit the high-voltage silicon stack. When a DC test is required, remove the short-circuit rod and connect the high-voltage silicon stack to the test circuit. At this time, the voltage in the circuit is a pulsating DC voltage. 2. The switching of AC/DC voltage in the experiment mainly depends on whether the short-circuit rod in the high-voltage insulation tower is removed. When the short-circuit rod is removed, the voltage on the high-voltage equalizing ball is DC voltage, and when the short-circuit rod is inserted, the voltage on the high-voltage equalizing ball is AC voltage. 3. Front panel DC/AC selection button. The status of this button cannot change the voltage properties of the device output. Pressing this button will simply connect the DC alarm circuit to the device. Instruct the user that when opening the box door, you need to discharge the high-voltage equalizing ball. Press the discharge device on the panel to make the end of the discharge rod contact the high-voltage equalizing ball. It is recommended that users keep the copper ball in contact with the high-voltage equalizing ball for more than five seconds each time they discharge. 4. In DC testing, the computer should also choose the DC state, otherwise the measured results will be incorrect. Simply put, there is a multiple relationship between AC voltage and DC voltage.

Voltage breakdown tester computer system and software package 1. The test software is a powerful, easy to operate, and intuitive display test software system developed by our company. 2.
