Abstract

The invention discloses a high-voltage and high-power uninterruptible power supply device which comprises a central control unit, a high-voltage switch cabinet, a high-voltage phase shift voltage transformation device, an uninterruptible power supply module unit, a high-voltage inversion transformer and a high-voltage metering control cabinet, wherein the central control unit is connected with the high-voltage switch cabinet, the uninterruptible power supply module unit and the high-voltage metering control cabinet; and the high-voltage switch cabinet, the high-voltage phase shift voltage transformation device, the uninterruptible power supply module unit, the high-voltage inversion transformer and the high-voltage metering control cabinet are sequentially connected with one another. With the high-voltage and high-power uninterruptible power supply device, the effect of uninterruptible power supplying for a key high-voltage and high-power electricity utilization occasion under industrial large production is achieved; and uninterruptible power supplying for 5-15 minutes is supplied to a key industrial load which outputs 10KV high voltage and has 1,250 KVA capacity.

Description

technical field [0001] The invention relates to the field of power electronics technology and the field of industrial automation intelligent power distribution, in particular to a high-voltage high-power uninterrupted power supply device. Background technique [0002] Modern industrialized large-scale production such as manufacturing, chemical industry, textile, pharmaceutical, petrochemical, etc. have put forward higher requirements for the stability and quality of power supply in some key processes, sections and processes. Any power failure or power supply flicker, flicker Failure to do so may cause irreparable losses to the production process and product quality, and even cause major production accidents or personal injuries. Therefore, in order to ensure the reliability of the production process and improve the quality of power supply, dual power supply circuits, intelligent switches and voltage stabilizing devices are usually configured in the above key areas to achieve...
