Abstract

The invention discloses a numerical control high-voltage direct-current generation device and method, and belongs to the technical fields of high-voltage and power supply. The numerical control high-voltage direct-current generation device comprises a rectifying module, a filtering and voltage-stabilizing capacitor C1, a DC / DC step-down module, a filtering and voltage-stabilizing capacitor C2, aninverter circuit, a high-frequency transformer, a voltage doubling rectifying circuit, a voltage-stabilizing decoupling capacitor C3, a resistance voltage divider and a controlling and driving system.Through adoption of the numerical control high-voltage direct-current generation device, a stable and reliable direct-current power supply is provided for a lightning arrester aging test power supplyof a high-voltage direct-current transmission system, so that the output current of a direct-current generator is improved. The direct-current power supply can be provided separately, or connected inseries with other corrugated power supplies to construct a special waveform generator. When the numerical control high-voltage direct-current generation device works in series with other power supplies, the direct-current output voltage waveform keeps stable, and high electromagnetic interference resistance is achieved.

Description

technical field [0001] The present invention relates to the fields of high-voltage technology and power supply technology, and more specifically, to a digitally controlled high-voltage DC generator device and method. Background technique [0002] The arresters used in high-voltage direct current (HVDC) transmission systems in power systems mainly include DC pole line arresters, neutral bus arresters, valve bridge arresters, valve arresters, and DC filter arresters. In these surge arresters, the voltage on the DC filter arrester does not have a DC component, so the AC voltage can be used to perform aging tests on the valve plate; the voltage on the neutral bus arrester and the DC pole line arrester is basically a pure DC voltage, so it can be used Use a high-voltage DC voltage generator to apply a pure DC voltage to perform an aging test on the valve plate. However, the voltage on the valve arrester and the valve bridge arrester is the superposition of DC voltage and pulsati...
