Interview:
A series of intelligent DC high voltage generators are mainly used in the power sector of the power sector, industrial and mining, metallurgy, steel and other enterprises to conduct DC withstand voltage tests or DC leakage on high voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers, generators, etc. Current test. Using AIPWM technology, the inaccurate linearity of PWM technology has been adjusted, and the precision of the instrument has been greatly improved. And use AI technology to set overvoltage protection and overcurrent protection to replace the problem that the digital dial switch can only set the voltage value, but cannot set the current value and voltage drift, and add AI automatic zinc oxide arrester measurement, automatic withstand voltage Test function, and can directly print the test report and save the test report, retaining the manual mode.
Features
(1) The full-automatic arrester test and stage test fully display the buck-boost process and withstand voltage time. (2) Grounding detection function, if the instrument is not safely grounded, the instrument will display a grounding reminder.
(3) Automatic withstand voltage test, complete display of the process of lifting and lowering, and the withstand voltage time.
(4) Using AIPWM technology, the inaccurate linearity of PWM has been adjusted, and the precision has been greatly improved. Ripple coefficient≤0.2%.
(5) The instrument has added perpetual calendar and time functions, and the experimental report has time and date.
(6) The pressure doubler adopts new material, which is light and strong. There are three built-in support feet at the bottom to increase the stability of the pressure doubler. The exterior is coated with special insulating materials, with good electrical performance and strong moisture resistance
