FORMATION TECHNICO-COMMERCIALE (NIVEAU I) 目录 目录 目录 目录 什么是发电机组 ? 磁场 正弦波的产生 频率公式 正弦波的形态 相位数 三相交流发电机 三相正弦波 需要记住的几个公式 电流 功率因数 : Fp or ?Cos???? 有功功率 / 视在功率 有功功率 / 视在功率 电功率 / 机械功率 机械功率: 单位 机械功率：计算 功率标定的不同类型 发动机的不同类型 柴油发动机 柴油发动机 进、排气系统 冷却系统 水冷却系统 燃油供应管路 燃油供应管路 燃油供应管路 进气系统的不同类型 One engine creates a mix air / combustible in proportions enabling the complete combustible combustion. Ideal mixture : 1 volume of fuel (combustible) implies 35 volumes of air. To increase the engine maximal power, one needs to increase both fuel and air quantity. 进气系统的不同类型 The maximum air volume that can be assimilated by an engine equals its cylinder capacity. For one given cylinder capacity, the admitted air intake quantity is : Proportional to its pressure Conversely proportional to its temperature To increase the power, one has to increase the air admitting pressure to lower its temperature 进气系统的不同类型 进气系统的不同类型 进气系统的不同类型 预热 减震器 速度调节 速度调节 电子式速度调节 电子调速器 电子调速器 柴油机的润滑系统 柴油机的润滑系统 发动机保护功能 发动机性能 发电机: 分解图 电压调节 6绕组发电机连接 12绕组发电机连接 发电机输出连接 发电机保护 发电机保护 简介 控制屏的不同类型 EMCP EMCPⅡ EMCP3 ATS The generator set control command is ensured with the electric panel enabling : CONTROL To watch the various genset parameters Mechanical (pressure, temperatures, levels, etc…) Electrical (voltage, intensity, power ratings, etc…) COMMAND To change the status of the genset (start-up, standstill, coupling, etc…) Command is ensured either through : Ignition key Pushing-button keyboard MANUAL PANEL (M50 or M150) : To start-up the generating set manually with an ignition key. AUTOMATIC PANEL (TELYS) : The automatic panel enables to start the generating set without human intervention closing-up the external contact. It also enables to start-up the genset in manual mode. COUPLING (PROCESS) : To put in parallel 2 or several generating sets between each others or networked Interest : In most cases, this enables to add their respective power There are three types of panels : M50 M150 Manual start panels fitted on the
