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.

结构特点：

1、船用配电板的基本结构形式分箱式、屏式和框架拼装式三种。

2、箱式结构适用于小型配电板，采用薄钢板折边成型后焊接而成，壁挂式安装，正面开门，板前维修。

3、屏式和框架拼装式解耦股适用于大中型配电板，其基本结构采用标准框架式型材拼装焊接而成。内部元件安装采用可卸式立体布置结构，安装、使用和检修都很方便；落地式固定安装，前后开门，可作双面维修。

4、可结合用户要求订制。

Structural features:

1、Marine switchboard has three basic strctural forms,box type,masked type and framed type.

2、Box switchboard is applicable for small-size switchboard and is welded with flanged steel sheet.lt is wall-mounted with opening in the front for maintenance

3、Masked and framed types are applicable for large-and medium-sizde switchboard and assenbled and welded with standard frame special section materials The inernal elements apply demountable standing structure which facilitates installation,use and maintenance,it is fixed o the ground with doors both in the front and back for maintenance.

4、Custonized types are availble.
