Abstract

The invention belongs to the technical field of electrical equipment and discloses a high-voltage charging set, which is provided with a collector power cabinet. The collector power cabinet is equipped with a plurality of IGBT converters and IGBT power distribution units. The IGBT converters and the IGBT power distribution units are connected through lines. A monitoring unit is connected with theIGBT converters and the IGBT power distribution units through lines respectively; and the IGBT power distribution units are connected with a multi-secondary-side high-voltage transformer through lines. The converters and the power distribution units of the high-voltage charging set adopt the IGBT transform technology, and adopt a high-voltage first-stage isolation transformation and efficient power distribution mode, and thus the formed system is more concise and efficient; through a separate-gun distribution power supply mode, each charging terminal can realize 64KW-512KW DC power; the high-voltage charging set is suitable for requirements of different vehicle types and different charging modes; conversion efficiency can reach up to 97%; and service life is long.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a high-voltage charging set. Background technique [0002] The traditional charging pile adopts a fixed power design, which has poor compatibility and low utilization rate, and is accompanied by the improvement of battery technology. Level, the existing charging piles cannot meet the future development needs, and most of them will be eliminated, which is a serious waste. This is also an important reason for many investors to stop and wait and see. [0003] To sum up, the problems existing in the prior art are: short service life, high operating noise; narrow applicable occasions; and poor compatibility. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention provides a high-voltage charging set. [0005] The present invention is achieved like this, [0006] The high-voltage charging set is an innovati...
