Problems solved by technology

[0004] With the increase of the centrifugal cascade design scale, the number of centrifuges required for a single intermediate frequency power supply is also increased. If the independent operation mode is still adopted, when one intermediate frequency power supply fails, the other intermediate frequency power supply needs to be equipped with additional centrifuges. Double the load, on the one hand, requires an increase in power supply capacity, on the other hand, load switching will cause disturbances, and low-frequency oscillations will occur, which will affect the safe operation of the centrifuge

Abstract

The invention provides a medium-frequency power supply synchronizing device for a gas centrifuge and is applied to technology of large power IGBT-PWM rectification inversion type medium-frequency power supplies of centrifuges. The device provided by the invention includes a single synchronization signal generating device and a synchronization redundancy control device. On one hand, the invention discloses a large power medium-frequency power supply synchronizing operation mode of the centrifuge. On the other hand, a technical problem of large load switch disturbance and consequently caused lowfrequency oscillation when single medium-frequency power supplies are in mutual standby application. Therefore, medium-frequency power supply possibility of the centrifuge is improved and technical conditions are provided for further design of larger scale centrifugation projects.

Description

technical field [0001] The invention belongs to the field of uranium isotope centrifugation separation, and is applied to the high-power IGBT-PWM rectification and inverter intermediate frequency power supply technology of centrifuges, which also includes advanced technologies in the fields of intermediate frequency power supply related power conversion, current conversion, and power electronics. Background technique [0002] The power supply of gas centrifuges adopts the way of one intermediate frequency power supply with loads of several centrifuges. The traceability of this technology comes from the centrifugal project imported from Russia. The centrifugal project imported from Russia is equipped with Russian intermediate frequency power supply. This type of intermediate frequency power supply is due to Using phase-controlled rectification and inverter technology, it has high harmonics, relatively low efficiency, and low power, and the number of centrifuges it carries is s...
