Abstract

The generating set department of Valmet Linnavuori Works, Finland, has during the last four years developed a new series of diesel generating sets, called Series V, in the output range of 30 to 180 kVA. The innovation came as a result of the development work, for which Valmet has taken out a patent and a protection of designs in many countries. The customer gets the real benefit of the new innovation. The total costs compared with those of traditional, noise-attenuated standby power plant solutions are about a quarter less. The basic planning criteria were small size and easy installation. The small size was achieved by installing the engine above the generator and by replacing the relay control by a programmable logic. The power from engine to generator is transmitted by the toothed belt which at the same time gives the possibility to drive the engine at higher speed than in the direct coupling. This means that more power can be taken from the engine, which also makes the size of the whole plant smal1er. The easy installation was achieved by packaging all the parts on a single base frame. The shape of the machine was chosen so that the whole machine will go in through a standard-sized fire door, whose frame is built into the outer wall of the future machinery room. The machine is hauled in through this door, and the opening is covered with a ventilation louvre delivered along with the machine.
建设备用电厂的新概念
芬兰维美德Linnavuori工厂的发电机组部门在过去四年中开发了一种新的柴油发电机组系列,称为V系列,输出范围为30至180千伏安。这项创新是开发工作的结果,维美德已经在许多国家获得了专利和设计保护。客户从新的创新中得到了真正的好处。与传统的、噪声衰减的备用电厂解决方案相比,总成本大约减少了四分之一。基本的规划标准是小尺寸和容易安装。小尺寸是通过将发动机安装在发电机上方,并用可编程逻辑取代继电器控制来实现的。从发动机到发电机的动力由齿形皮带传递,同时使发动机以比直接联轴器更高的速度驱动成为可能。这意味着可以从发动机获得更多的动力,这也使整个工厂的规模更小。通过将所有部件包装在一个基础框架上,实现了易于安装。机器的形状是这样选择的,整个机器将通过一个标准尺寸的防火门,其框架建在未来机械室的外墙。机器通过这个门被拖进来,开口上盖着一个与机器一起交付的通风百叶窗。
