The DC high-voltage generator has a variety of protection functions, such as low-voltage overcurrent, low-voltage overvoltage, high-voltage overcurrent, high-voltage overvoltage, zero-cross protection, ungrounded protection and other protection functions. The high-voltage DC generator also has Chinese alarm prompts and voice prompts .
1. Internal voltage measurement circuit open circuit protection: When the internal pressure measurement resistor is open circuit, the voltage measurement signal line is open circuit, and the cable terminal is in poor contact. If there is no protection, the voltmeter of the instrument has no indication, but there is voltage at the high voltage end, which may cause personal injury.
2. Over-current protection: When the high-voltage output is short-circuited, the instrument should cut off the output immediately without damaging the instrument.
3. Overvoltage protection: When the high voltage output exceeds the overvoltage set value, the instrument should automatically cut off the output immediately to ensure that the measured object will not be damaged due to overvoltage.
4. Zero position protection: The potentiometer should be reset to zero and boosted, so as to avoid the voltage on the high voltage end, which will cause harm to the human body and the instrument.
5. Grounding protection: When the DC high voltage generator is not grounded or poorly grounded, the instrument should have a grounding alarm and corresponding prompts, and cannot boost the voltage to prevent damage to the human body and the high voltage DC generator.
