阿尔塔什水利枢纽工程厂用低压配电系统设计探讨

Design Discussion on Low-Voltage Distribution System for Factory Use in Altash Water Conservancy Project

新疆阿尔塔什水利枢纽工程电站厂配电系统采用10kV和0.4kV两级电压供电,电站装机容量规模较大,各类厂用电负荷容量也很大。文章对电站厂用低压配电系统的接线方式、配电装置、保护装置的配置方案等进行了介绍,并以具有代表性的机组技术供水泵电动机配电为例,通过计算选择了断路器并进行了复核。

The power distribution system of the power station of Xinjiang Altash Water Conservancy Project adopts 10kV and 0.4kV voltage for power supply.The installed capacity and scale of the power station are large,and the power load capacity of various plants is also large.This paper introduces the wiring method,distribution equipment,and protection device configuration of the power station’s low-voltage distribution system for factory use.Taking the typical power supply pump motor distribution as an example,the circuit breaker selection is calculated and reviewed.
