AP1000电气高精度预埋件安装控制技术

摘要

There is plenty of embedment for the electric cabinet in AP1000 PWR nuclear power plant. The embedment is cast-in-place, and the length of embedment is longer as compared with the width and thickness, with high installation accuracy, which is hard to meet the specific tolerance when transport and install the embedment. In order to install the electric cabinet smoothly and achieve the milestone of initial-energization, the control measure for the embedment from fabrication to installation is taken to make sure the installation accuracy.%A P1000压水堆核电机组中，存在大量为电气盘柜使用的电气预埋件，埋件长度长，但宽度以及厚度相对较小，在运输以及安装过程中极易发生变形，且该类型埋件安装精度要求高，按照普通埋件加固难以满足公差的要求。为了保证后续电气设备的安装以及倒送电节点的顺利实现，对于电气高精度预埋件，从加工制作、运输以及现场安装进行了一系列的控制措施，以保证此类埋件的安装精度。
