电力工程施工中 ,导线的连接是一道重要的工序。目前 ,对接地系统的引下线和地网施工使用气焊或电弧焊工艺。由于该工艺设备笨重 ,给野外施工带来不便。火泥熔接是利用金属氧化物与铝粉的化学反应热加热母材、熔融金属 ,使母材表面熔化 ,金属与母材金属相熔合 ,在模具的型腔中形成熔焊接头。火泥熔接工艺装备简单、携带方便、适用于野外的熔接、操作便捷、易于控制品质 ;对导线的绝缘破坏较少、无残余应力、不会产生腐蚀和松弛 ,接头性能稳定可靠。火泥熔接技术在电力工程中的实际应用效果较理想 ,有一定的推广价值
Power engineering construction, the wire connection is an important process. At present, the grounding system of the downline and ground network construction using gas welding or arc welding process. As the process equipment bulky, inconvenience to the field construction. Fire mud welding is the use of metal oxide and aluminum chemical reaction heat the base metal, molten metal, so that the base metal surface melting, metal and base metal phase fusion, the mold cavity in the formation of welded joints. Fire mud welding technology and equipment is simple, easy to carry, suitable for field welding, easy operation, easy to control the quality of the conductor less damage, no residual stress, corrosion and relaxation will not produce, the joint performance is stable and reliable. Fire mud welding technology in the practical application of electrical engineering effect is better, there is a certain promotional value
