车间配电所的整体设计 摘 要 配电所就是对电能进行接受、分配、控制与保护。它由电力变压器、配电装置和二次装置等构成，变电站及配电系统在电网与用户之间起着重要的连接作用。随着电力系统的发展，电气化和自动化给国民经济和社会发展带来了巨大的动力和效益，并成为当今社会发展和人民日常生活中不可缺少的重要能源。但若管理或是系统设计存在缺陷，会容易造成用电质量低下，更有甚者造成电网崩溃，严重时电网瓦解，酿成大面积停电。 本次设计是关于车间配电所的设计。最先从车间的布局考虑，参考了现在很多工厂的平面设计图对各部分的布局的可用性和经济性入手。接下来开始进入工厂厂区的供电设计部分。先从各部分的计算入手，其中包括计算负荷和短路电流的计算和一次设备稳定度的效验，及低压配电屏的选择。接下来，进行了对变电所高压进线和低压出线的选择，车间配电线路的设计。在变电所二次回路设计及继电保护整定当中我考虑了各方面的保护及对保护器具的选择。变电所设计自然少不了对防雷以及接地保护方面的设计，考虑到了车间布局的实际情况进行了对防雷接地设备的选择和设计。 关键词：供电设计 低压配电 车间配电所 高低压设备 电力系统 Overall design of workshop distribution Abstract The so-called distribution is to receive, electricity distribution, control and protection. Distribution of power transformer, power distribution device and the second device, etc, substation and distribution system in the power grid plays an important role in connection with the user. With the development of electric power system, electrification and automation to the national economy and social development are of great power and benefit, and become the current social development and Peoples Daily life indispensable important energy. But if the management or the defect of system design, will be easy to cause the low quality of electricity, moreover caused by power grid collapse, serious when grid collapse, caused widespread power outages. This design is about the workshop of substation design. First from the layout of the workshop, consulted a lot of factory floor plan now for the availability and economy of the layout of the part. Then begin to enter the plant power supply design. First from the calculation of the parts, including the computational load and short circuit current calculation and the equipment stability at a time of efficacy, and the selection of low voltage distribution panel. Next, has carried on the choice of substation high voltage into the line and the low pressure outlet, workshop distribution circuit design. In the substation of secondary loop design and relay protection setting I consider all aspect
