DC high voltage generator adopts medium frequency voltage doubling circuit, new DC high voltage generator applies PWM pulse width modulation technology and high power IGBT devices, according to the theory of electromagnetic compatibility, adopts special shielding, isolation and grounding measures. The DC high voltage test realizes high quality, portable and can withstand rated voltage discharge without damage. DC high-voltage generator has a variety of protection functions, such as: low-voltage over-current, low-voltage over-voltage, high-voltage over-current, high-voltage over-voltage, zero-position protection, not grounded protection. Intelligent DC high-voltage generator using fault sampling special sensors, action time for nanoseconds, optical isolation elements are also nanoseconds, action time is generally 10 microseconds can completely shut down the main DC circuit. Push the signal fast shutdown protection in the output side using a special sensor sampling, reaction time of nanoseconds, through the nanosecond optical isolation elements and nanosecond analog switch, the whole process in 2 microseconds to cut off the amplifier circuit to push the signal, to ensure that in the case of output short-circuit, do not damage the power device. It refers to the high-voltage power supply mainly used in insulation and leakage detection, and now there is no strict difference between high-voltage power supply and high-voltage generator.
DC high voltage generator is the first in the industry to adopt the sectionalized structure, that is, it can be used for both high voltage level and lower voltage level, and keep its accuracy unchanged. Take 100/200kV/2mA divided into two sections as an example, a single section can do 100kV/2mA use, can be used for 35kV and the following system of electrical equipment DC high-voltage test, at this time to ensure that the accuracy of the measurement to avoid the big maratos; two sections of the use of the use of 200kV/2mA can be done. It can be used for 220kV section, 110kV and below zinc oxide lightning arrester DC test and cross-linked cable DC withstand voltage test. It can be used for two purposes in one machine, which is very convenient for users on the spot. It is mainly used for researching the insulation strength of electrical equipment DC precision and converter station equipment and insulating materials under DC high voltage, corona and ionic current and its effect of DC power line, as well as conducting leakage current test of AC and DC power equipment. In addition, they can be used as a power source for other high-voltage test equipment, such as shock voltage generators, shock current generators and oscillation loops. In other fields of science and technology, such as physics gas pedals, electron microscopes, electronic medical equipment, X-ray, industrial applications, exhaust gas precipitation, electrostatic spraying paint, or electronic communications, television, broadcasting stations, etc. are also widely used.
