用途：
PDJ系列船用配電板適用于三相AC400V/50Hz或AC450V/60Hz、單機功率自20KW至1600KW及DC30V以下船舶交直流系統，用來控制、監視和保護發電機。配電板分主配電板及應急配電板兩種：主配電板直接和主發電機相連，把主發電機發出的電能或岸電送來的電能分配至遠外的二極分電裝置或直接分配給用電負載；當主電源失電后，應急配電板向一些重要設備供電（如應急照明、操縱裝置、導航和無線電設備等）。
配電板的制造符合GB11634-88《船用交流低壓配電板通用技術條件》、GB11803-89《船用交流低壓配電板結構及基本外形尺寸》及各船級社規范要求。
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.
結構特點：
1、船用配電板的基本結構形式分箱式、屏式和框架拼裝式三種。
2、箱式結構適用于小型配電板，采用薄鋼板折邊成型后焊接而成，壁掛式安裝，正面開門，板前維修。
3、屏式和框架拼裝式解耦股適用于大中型配電板，其基本結構采用標準框架式型材拼裝焊接而成。內部元件安裝采用可卸式立體布置結構，安裝、使用和檢修都很方便；落地式固定安裝，前后開門，可作雙面維修。
4、可結合用戶要求訂制。
