| 摘 要： | 电热采暖系统分支回路一般为单相配电,因此在相序分配时一定要保持均衡,最大相负荷电流不宜超过平均值的115%,最小相负荷电流不宜小于平均值的85%。调研发现某项目设计图看起来三相平衡,但由于计算机网络集中控制系统分时分区运行,编程没有注意相序组合,造成运行时存在较大偏差。

| Abstract: | Due to the fact that the branch of electrothermal heating system is usually single-phase powered,the phase sequence must be distributed evenly with max.phase load current not over 115 % of mean value and min.phase load current not less than 85 % of mean value.It is found by investigation that the design drawings for a project appear to be three-phase balanced,however,bigger deviation is available during operation because of time /zone devision operation of integrated control system for computer netwrok and ... |
