Abstract:
    The utility model relates to a kind of high-frequency high-voltage power supply for electrical dust collection to solve shortages that volume of normal thyristor power is big and ineffective, mean voltage of output is low, current output is small, spark extinction time is long, field energy recovery is slow and easy to generate counter corona phenomenon etc. The utility model adopts three-phase network source input and gets through breaker, contactor, three-phase rectification bridge and after smoothing reactor charges to electrolysis capacity, it forms direct supply. The direct supply is high frequency inversion with local parallel resonant circuit through full bridge series resonant circuit. It makes high frequency silicon stack rectified output direct supply boost pressure through high frequency transformer and through damping resistance to supply for dust collector. It can apply three-phase supply, electric network equalization with constant-current characteristic to boost device efficiency and dust collection efficiency. It can operate stably under overloading and light load. The output voltage and current is big under middle, low specific resistance dust and it can suppress counter corona phenomenon under height ratio resistor dust to run with high efficiency and reliable.
