一. 概况Overview

1.1 工程概况Project Overview

项目名称：

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、接地电缆敷设所需电缆沟的开挖工程。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 trench excavation project among three substations and for MV users connected to the three substations.

1.2 施工范围Scope of Work

1) 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) 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) 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，马达回路采用10kV截面为95mm2的三芯铠装电缆。以上电缆线路均沿规划路径埋地敷设。10 10kV lines led from C581 are used to supply power to A507's four transformers, B551 two transformers, B553TDA 2 sets of hydrogen compressor unit, C521 hydrochloric acid chlorine gas compressor unit, and hydrochloric acid compressor unit respectively. Among them, transformer circuit uses x 3-core armored cable with 10kV cross-section 185mm2, motor circuit uses three-core armored cable with 10kV cross-section 95mm2. All cable lines will be laid underground along the planning path.

4) 接地电缆回路：Ground cable loop:

从A472敷设一根95mm2裸铜线去C581，同时从C581敷设四根95mm2裸铜线，分别引至B551、A507、B553和C521，作等电位联结。以上电缆线路均沿规划路径埋地敷设。Lay a 95mm2 bare copper wire to C581 from A472. Meanwhile lay four bare copper wires to B551, A507, B553 and C521 for equipotential bonding. All cable lines will be laid underground along the planning path.

5）本工程电缆沟走向如下：The cable trench directions are as follows:

电缆沟南线为A472至C581，全长约850米，根据K-K断面图：开挖深度为1米，沟槽底宽0.6米，沟槽面宽约1.1米。Cable trench south line is from A472 to C581 about 850 meters long.
