1.发电机控制箱(屏)是同步发电机组的配套设备,主要是控制发电机送电及调压。小容量发电机的控制箱一般(经减震器)直接安装在机组上,大容量发电机的控制屏,则固定在机房的地面上,或安装在与机组隔离的控制室内。
8.3.7 Installation of Electrical System
1. Generator control cabinet and panel are auxiliary devices synchronous to the generator set, mainly used to control electricity distribution and voltage adjustment. Generally, control box of small capacity generator would be installed directly onto the generator set. For large capacity generator set, the control panel would be fixed on the workshop ground, or in a control room separated from the generator set.
开关箱(屏)或励磁箱:各生产厂家的开关箱(屏)种类较多,型号不一,一般500kW以下的机组有柴油发电机组相应的配套控制箱(屏),500kW以上机组,可向机组厂家提出控制屏的特殊订货要求。
Switch box (panel) or magnetic excitation box: There are many different switch boxes (panels) from different manufacturers with different types. In general, if the diesel generator set is under 500kW, matched control box (panel) would be supplied with the generator set; if it is over 500kW, clients can make special order for control panels.
 
2.成套配电柜箱的安装应按本规程第6章,成套配电柜,控制柜(屏,台)和动力;照明配电箱(盘)安装的有关条款执行。
2. Installation techniques of complete set of distribution box should observe chapter 6 of this regulation and relevant specifications of packaged electricity distribution cabinet, control cabinet (panel, desk), power, and lighting electricity distribution box (board), etc.
 
3.发电机组接线:
(1)发电机及控制箱接线应正确可靠。馈电出线两端的相序必须与电源原供电系统的相序一致。
(2)发电机随机的配电柜和控制柜接线应正确无误,所有紧固件应紧固牢固,无遗漏脱落。开关,保护装置的型号,规格必须符合设计要求。
3. Wire connection of the generator set
(1) The wiring of the generator and control box should be correct and reliable. The phase sequence of both sides of outgoing feeders should be identical to those of the power supply system.
(2) The wiring of the power distribution cabinet and control cabinet supplied with the generator should be correct, and all fastening parts should be firm enough, free of any omission or detachment. The specifications and types of switches and protective devices should conform to design requirements.
 
4.安装地线:
(1)发电机中性线(工作零线)应与接地母线引出线直接连接,螺栓防松装置齐全,有接地标识。
(2) 发电机本体和机械部分的可接近导体均应保护接地(PE)或接零线(PEN),且有标识。
(3)发电机组的接地装置,应按设计要求施工,作法按本标准24章,接地装置安装有关条款执行。
4. Ground Wire Installation
(1) The neutral wire of the generator (work zero line) should be directly connected to the leading-out line of the grounded bus bar. The bolt counter loosing devices should be complete and equipped with grounding label.
(2) The accessible conductors of generator and mechanical section should all equipped with protected earth wire (PE) or neutral and protected earth wire (PEN), along with clear label.
(3) The grounding devices of the generator set should be installed according to design requirements, whose techniques conform with chapter 24 of the present standard and relevant regulations of grounding device installation.
