用途：
PDJ系列船用配电板适用于三相AC400V/50Hz或AC450V/60Hz、单机功率自20KW至1600KW及DC30V以下船舶交直流系统，用来控制、监视和保护发电机。配电板分主配电板及应急配电板两种：主配电板直接和主发电机相连，把主发电机发出的电能或岸电送来的电能分配至远外的二极分电装置或直接分配给用电负载；当主电源失电后，应急配电板向一些重要设备供电（如应急照明、操纵装置、导航和无线电设备等）。
配电板的制造符合GB11634-88《船用交流低压配电板通用技术条件》、GB11803-89《船用交流低压配电板结构及基本外形尺寸》及各船级社规范要求。
PDJ marine switchboard is applicable to three-phase A400V/50Hz or AC450V/60Hz ship AC system with unit power ranging from 20KW to 1600KW and ship DC system lower than DC30V for controlling,monitoring and protecting the generator.Switchboard is divided into main switchboard and emergency switchboard.The main switchboard the main generator or from the shore power station to the secondary distributing device or dierctly to the poewer load. Lf the main sweichboard fails,the emergency switchboard supplies power for important eqipment such as emergency lighting,steering devices,navigation and radio equipment ,etc.
The switchboard complies with requiremnets of GB11634-88 Marine AC Low Voltage Switchboard-General Specification and GB11803-89 Marine AC Low Voltage Switchboard-Construction and Basic Dimension as well as classification societies.
