电缆敷设采用EC软件,8个人用1.5个月时间完成电缆敷设的设计任务。
主厂房内每台300MW机组自动化专业的电缆根数为4038根。
主厂房内每台300MW机组自动化专业的电缆长度为350公里。
以上电缆的根数及长度均不包括全厂火灾报警的厂供电缆和全厂各辅助生产车间的电缆。
电缆桥架的立柱、桥架及小槽盒全部选用钢制镀锌,每台机组约95吨。
其它电缆桥架包括直通、弯通、三通、四通、盖板、终端封头、调宽片、直接片等选用铝合金材质,每台300MW机组约为55吨。附件随桥架提供(如螺栓、螺母)。
某电厂,4×MW燃油燃气电站。热力系统为单元制。DCS采用TELEPERM-XP。每台机组设计I/O点数为5804点。
电缆敷设采用EC软件,12个人用2.5个月时间完成电缆敷设的设计任务。
主厂房内每台325MW机组自动化专业的电缆根数为4413根。
主厂房内每台235MW机组自动化专业的电缆长度为360公里。
每台机组全部选用钢制镀锌电缆桥架,其重量约为200吨。
电站的电缆可以分为六大类:高压电力电缆、低压电力电缆、控制电缆、热控电缆、弱电电缆(主要指计算机用电缆)、其它电缆。若两台300MW机组同时做电缆敷设,自动化专业电缆的数目大约有8500根左右。其中热控电缆和弱电电缆将大于5000根,即约占60%左右(以根数计量)。
