Product Introduction:
High-frequency voltage doubler circuit, advanced PWM high-frequency pulse width modulation technology, closed-loop adjustment, and large voltage feedback are used to greatly improve the voltage stability. Use high-power IGBT devices and drive technology with superior performance, and adopt special shielding, isolation and grounding measures according to the electromagnetic compatibility theory. The DC high voltage generator realizes high quality, portable, and can withstand the rated voltage discharge without damage. It has the characteristics of large output power and small size, and has reliable overvoltage, overcurrent and zero closing protection functions, with 0.75 times voltage switching function.
It is mainly used for DC withstand voltage test or DC leakage current test of high voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers, generators, etc. in power departments, industrial and mining, metallurgy, steel and other enterprises.
Operating Steps:
(1) Input power detection and voltage regulator return to zero.
(2) Connect the three-phase power line and the neutral line to the corresponding terminal on the back of the test bench, and the test transformer reliably grounds the ground bolt of the test bench cabinet;
(3) Close the external power switch;
(4) Turn the "master control power switch" to the "on" position. At this time, the red light of the "power indication" switch cabinet power-on test bench, all meters and the "green light of the button with light" are on.
(5) Turn the "three-phase four-wire power supply voltage conversion switch" to "CA", "BC", and "AB" to display the corresponding line voltage (380V).
(6) The zero return operation of the regulator:
Why choose our electrostatic generator?
1. Smaller size, lighter weight, more beautiful, more reliable, easy to operate, complete functions, easy to use in the field, it is the ideal and reliable product in the new century.
2. Using the most advanced technology and process manufacturing, the first applied PWM high-frequency pulse width modulation technology, pulse train logic array modulation, high-power IGBT devices, using high-frequency technology to increase the frequency, the frequency is up to 100kHz, so that the output high voltage stability Higher, the ripple factor is smaller.
3. According to the maintenance-free design, the main components are all imported advanced technology components from the United States, Germany, Japan and other countries, which are durable and are not afraid of continuous direct short-circuit discharge to the ground.
4. High precision and accurate measurement. Both the voltage and current meters are digitally displayed, with a voltage resolution of 0.1kV and a current resolution of 0.1uA. The voltmeter on the control box directly displays the voltage value added to the load sample. There is no need to add a voltage divider during use, and the wiring is simple. The instrument has high and low voltage ends to measure the leakage current, and the high voltage end adopts a circular shielded digital meter to display, which is not afraid of discharge shock, has good anti-interference performance, and is suitable for field use.
Also have other model static generator for IML
