Giơi thiệu sản phẩm
KDZG series DC high voltage generator is a portable DC high voltage generator researched and manufactured according to the requirements of Chinese industry standard ZGF24003-90 “General Technical Conditions for portable DC High voltage generator”. It is suitable for DC high voltage test of zinc oxide arrester, magnetic blow arrester, Cáp điện, generator, máy biến áp, switch and other equipment in power department, factory and mining enterprise power department, scientific research unit, đường sắt, công nghiệp hóa chất, power plant, vân vân.
KDZG series DC high voltage generator adopts medium frequency voltage doubling circuit, applying PWM medium frequency pulse width modulation technology, closed-loop adjustment, using voltage feedback, so that the voltage stability is greatly improved. The high power IGBT device and its driving technology are used, and special shielding, isolation and grounding measures are adopted according to electromagnetic compatibility theory. The DC high voltage generator has high quality, cầm tay, and can withstand rated voltage discharge without damage.
The main components of KDZG series DC high voltage generator instrument are selected from the United States, Germany, Japan and other countries, so that the instrument is more reliable and stable, the pressure doubling cylinder is small, the capacity is large, the overload capacity is strong, and the field operation test is convenient. Our company regards quality and reputation as life, constantly improve the level of science and technology, and develop high-quality products to meet the needs of users.
Technical features:
1, smaller volume, lighter weight, more beautiful, đáng tin cậy hơn, dễ dàng hoạt động, full function, easy to use in the field.
2, the application of PWM intermediate frequency pulse width modulation technology, pulse train logic array modulation, the use of high-power IGBT devices and voltage feedback, so that the output high voltage stability is higher, the ripple coefficient is smaller.
3, the main components of the instrument are selected from the United States, Germany, Japan and other countries, durable, not afraid of continuous direct short-circuit discharge.
4, độ chính xác cao, phương pháp đo lường chính xác. Voltage and ammeter are digital display, voltage resolution is 0.1kV, current resolution is 1uA, the voltage meter on the control box directly displays the voltage value added to the load test, no need to use the voltage divider, simple wiring. The instrument has a high and low voltage end to measure the leakage current, and the high voltage end is displayed by a circular shielded digital meter, which is not afraid of discharge impact and has good anti-interference performance, and is suitable for field use.
5, high voltage regulation stability, full range smooth voltage regulation, output voltage regulation using imported single multi-turn potentiometer, stable voltage boost process, high adjustment accuracy. 6, negative polarity output, zero start, điều chỉnh liên tục, over voltage, over current, back to zero, ground protection, special break line protection and other protection functions. The automatic protection circuit has strong function, perfect and reliable protection, so that the operation is safe, and various technical indicators are better than the industry standard.
7, add a high precision 75%VDC-1mA function, do zinc oxide arrester measurement to bring convenience. One click does not count. The instrument control box has 75% of the voltage function key, when doing the arrester test, when the current rises to 1000uA, press the 0.75UDC–1mA button, then the voltmeter, ammeter displayed value is 75% of the data, after the completion of the voltage regulator potentiometer should immediately return to zero, and should immediately press the green button, Cut off the high voltage and turn off the power switch. Let’s do some other tests.
8, convenient overvoltage setting function, the use of digital dial switch, the setting voltage value can be visually displayed, so that you operate more freely, display value unit is kV.
9, the double pressure cylinder is developed and produced by the United States technology, and the intermediate frequency transformer is specially designed by relevant experts, kích thước nhỏ, large capacity, strong overload capacity, which is convenient for field operation test.
10-1, the bottom is provided with three internal support feet, increasing the stability of the pressure doubling cylinder. (for 200kV) 10-2, the top cover of the control box can be used as a windproof base, which can be inserted with the pressure doubling cylinder to enhance the stability of the pressure doubling cylinder.
