用途：
PDJ系列船用配電板適用于三相AC400V/50Hz或AC450V/60Hz、單機(jī)功率自20KW至1600KW及DC30V以下船舶交直流系統(tǒng)，用來控制、監(jiān)視和保護(hù)發(fā)電機(jī)。配電板分主配電板及應(yīng)急配電板兩種：主配電板直接和主發(fā)電機(jī)相連，把主發(fā)電機(jī)發(fā)出的電能或岸電送來的電能分配至遠(yuǎn)外的二極分電裝置或直接分配給用電負(fù)載；當(dāng)主電源失電后，應(yīng)急配電板向一些重要設(shè)備供電（如應(yīng)急照明、操縱裝置、導(dǎo)航和無線電設(shè)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(shù)條件》、GB11803-89《船用交流低壓配電板結(jié)構(gòu)及基本外形尺寸》及各船級(jí)社規(guī)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(jié)構(gòu)特點(diǎn)：
1、船用配電板的基本結(jié)構(gòu)形式分箱式、屏式和框架拼裝式三種。
2、箱式結(jié)構(gòu)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(jié)構(gòu)采用標(biāo)準(zhǔn)框架式型材拼裝焊接而成。內(nèi)部元件安裝采用可卸式立體布置結(jié)構(gòu)，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(jié)合用戶要求訂制。
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.
