一. 概况 Overview
1.1 工程概况 Project Overview
项目名称: TDI联合装置厂区中压电缆敷设施工。Project name: TDI Train Plant Medium Voltage Cable Pulling Work.
本工程涉及三个变电站,分别是现有的220/35kV A472变电站、现有的35/10kV B301S变电站以及新建的35/10kV C581变电站,工作内容为三个变电站之间和从三个变电站接至MV用户的电力电缆、控制电缆、接地电缆的敷设。The project involves three substations, namely the existing 220/35kV A472 substation, the existing 35/10kV B301S the 35/10kV C581 substation and a new substation. This is the power, control and grounding cable pulling among three substations and for MV users connected to the three substations.
1.2 施工范围 Scope of Work
1) A472建筑(220/35kV变电站)出线回路:A472 Building(220/35kV substation) outlet circuit
由A472变电站引出3路35kV出线。其中:
一路引至B301S建筑(35/10kV变电站)原1#主变,原1#主变电缆将抽出,与新增4#主变连接;另两路引至35/10kV C581变电站1#主变和2#主变。回路采用FS-YJY-26/35kV-1*300mm2单芯电缆,直埋敷设。去C581的两路35kV线路,敷设时沿不同路径,以避免两回线路同时受损。Pull three 35V outgoings from A472 substation. Of which: The first outgoing is led to B301S Building (35/10kV substation) the original one # main transformer, pull the original one # main transformer cable out, and connect to the adding 4 # main transformer; the other two outgoings are led to 35/10kV C581 # 1 and substation 2 # main transformer. Use FS-YJY-26/35kV-1 * 300mm2 single-core cables for Loop and buried pulling. Two 35kV lines to C581 are laid along different paths to avoid damage of the two loops.
2) B301S建筑(35/10kV变电站)出线回路:B301S building (35/10kV substation) outlet circuit:
由B301S变电站引出7路10kV出线。全部引至B399中心制冷站。回路采用10kV截面为95mm2的三芯铠装电缆,由B301S南面现有的电缆井引出直埋至装置。Pull 7 10kV outgoings from B301S substation to B399central refrigeration station. Loop uses 10kV three-core armored cable with cross-section 95mm2 and pull out from the existing cable well in the south of B301S then buried lay to the device.
3) C581建筑(35/10kV变电站)出线回路:C581 building (35/10kV substation) outlet circuit:
由C581引出10路10kV线路,分别为A507的四台变压器,B551的两台变压器,B553TDA装置氢气压缩机2台,C521盐酸装置氯气压缩机1台,盐酸压缩机1台提供电源。其中,变压器回路采用10kV截面为185mm2的三芯铠装电缆
