Открытый высоковольтный испытательный стенд (ВНИЦ) ВЭИ - Outdoor high voltage test stand


Аэровидеосъемка открытого высоковольтного испытательного стенда Всероссийского электротехнического института.

Стенд ОВИС ВНИЦ ВЭИ представляет собой комплекс научно-исследовательских и испытательных установок, основной из которых является сверхмощный генератор импульсных напряжений (напряжение на выходе до 6 MB), площадок, подъездных путей, телекоммуникаций, помещений для размещения измерительного оборудования и персонала.

Стенд оснащен оборудованием для измерения электромагнитных параметров импульсов высокого и сверхвысокого напряжения, формируемых на его установках, специальным оборудованием для регистрации оптических и электрических пространственно-временных параметров процесса развития разряда в воздухе, в том числе и прямое измерение электрических полей в исследуемом изоляционном промежутке в диапазоне величин, характерных для длинной искры и молнии.

Study on the Voltage Balancing Inverter for UPS Byeon, Yong Seop Department of Electrical Engineering Graduate School, Myongji University Directed by professor Lee, Jun Young
This paper suggests another candidate the Voltage Balancing Inverter for UPS. Recently A commercial power interruptions and voltage variations of sensitive high-tech equipment for industrial, medical equipment, computers, finance, office equipment, such as the use of high use of digital information processing equipment with high reliability while increasing the uninterruptible power system to the growing reality. In this paper, we propose an inverter circuit forming the voltage balance itself without a separate control element. The proposed circuit is to carry the charge of the voltage relative to the high voltage side of the capacitor using the charge moving toward the low voltage and is naturally to balance. The proposed circuit is not required voltage balance controller can be used as a single controller. Even though the number of switches are more than conventional half-bridge inverter structure that can use a rated voltage of the high-speed switch to a lower half of the rated voltage of the conventional circuit.
The validity of proposed system could be verified by simulations, circuit fabrication and experiments.
