Medium Voltage Shore Power Distribution Board
1. Overview
The JDMVSB series medium voltage shore power connection distribution board is one of the core components of the medium voltage shore power system. Its main function is to achieve safe and smooth switching and connection between ship power and shore power, and to distribute, control, and monitor the connected shore power, ensuring that the shore power can stably and reliably replace ship auxiliary equipment and supply power to ship loads. It is a key guarantee for achieving “zero emissions and silent port docking”. The design and manufacturing of this series of products comply with the following specifications:
- IEC 62271-200:2021 “Rated voltage 1 kV and above to 52 kV and below AC metal – enclosed switchgear and control gear”
- IEC 62271-1:2017 General Specification for AC Switchgear and Control Equipment
