25、艺操作手册 中接头焊接照片指南及相关要求施工。焊接原理：热熔焊是一种使铜和铜、或铜和钢进行电气连接的方法。此过程不需要外部的热源或动力。施工过程中，颗粒状金属（焊药：粒状氧化铜和铝）从一个容器倒入石墨锅并燃烧，通过铝（放热反应）跟氧化铜的化学反应产生液态铜和氧化铝渣。渣浮到表面和钢碟熔化，使得液体铜流进焊洞并完成一次焊接。随之焊接头固化，拿掉模具并准备下一次焊接。4.2 放热焊接工艺优点：4.2.1、焊接点的载流能力（熔点）与导线的载流能力相等。因为焊接点是焊接成的，所以是永久性的，不会老化。4.2.2、焊接是一种永久性的分子结合，不会松脱。4.2.3、焊接点像铜一样，不易受腐蚀性物质的影响。
26、4.2.4、焊接点能经受反复多次的大浪涌故障电流而不退化。4.2.5、焊接方法简单，培训容易。4.2.6、供焊接用的材料及工具很轻，携带方便；进行焊接时，无需外接电源或热源，从外观便能核查焊接的质量。4.2.7、可用于焊接铜、铜合金、镀铜钢、各种合金钢及高阻加热热源材料。4.2.8、采用镀铜钢棒由实心冷抽钢棒冷镀上厚度一致的铜，如同冶金连接铜与钢棒。铜层与钢棒完美结合，容易打入地下，铜皮不破裂，不脱落，极大地延缓腐蚀时间。4.3 热熔焊施工顺序：基槽开挖验槽领取接地材料铺设接地体（铜排、铜绞线、垂直接地体）清理模具及接地体接头加热模具和接地体接头（干燥）接头放入模具中夹紧检查是否夹紧装入焊药盖

35、m,上方宽 1.5m的梯形，换填陶黏土后应夯实，待水平接地体的沟挖好后，应通知监理单位对基槽进行验收，符合设计要求后再进行下步工序的施工。4.3.2、垂直接地极安装：根据设计图纸中垂直接地极安装位置进行测量、定位，确定钻孔地点，当土壤情况良好（如粘土），可不进行钻孔，直接将接地极铜棒压入土壤中；但当土壤情况不好（如含碎石碎砖或岩石），为了保证安装过程中不对接地极表面的铜层造成损坏，则必须进行钻孔安装。在沟槽开挖完成后，对需钻孔的土壤可根据土壤情况选择钻孔机械，当土质为粘土时，可用触探仪进行钻孔，对含石头或岩石的土壤，可用小型地质钻孔机械进行钻孔。接地极安装孔钻孔应根据垂直接地极的直径和长度来确
36、定钻孔规格，现需要打孔安装的垂直接地极为12 长 2.5m 的铜棒，打孔时孔径应比接地极直径稍大1020 mm，孔深应略大于接地极长度，同时应保证孔的垂直性，以方便接地极的安装。将垂直接地极安装于打好的孔中，注意安装过程中不能造成接地极端头变形损坏，以备后续焊接作业；4.3.3、水平接地网安装：站内接地以敷设水平接地网为主，垂直接地体为辅。主接地网选用?10 的铜棒，焊接成 5M 5M方孔网格状水平接地网，其外缘为闭合的圆弧形，圆弧半径不宜小于均压带间距的一半(取 R=6M)。为减少腐蚀，水平接地极一般为竖放，通过与垂直接地极的焊接构成一个网形整体；建筑物基础和设备基础下用200mm2铜绞线敷
