随着电力工业向大容量、高电压方向发展,对导线和接地线接头的连接品质提出了更高的要求。我们在浙江北仑二期工程中(单机容量为60万kW),使用放热焊接技术,仅主厂房接地线长度就有10500m,共有接点3200个,焊接质量颇好,通过了北仑公司的验收,并得到了有关方面的好评。后又在扬州电厂二期、天荒坪抽水蓄能电站、 With the power industry to large-capacity, high-voltage direction, the wire and ground wire connector connection quality put forward higher requirements. We are in Zhejiang Beilun Phase II project (stand-alone capacity of 600,000 kW), the use of exothermic welding technology, only the main plant grounding line length 10500m, a total of 3200 contacts, the welding quality is quite good, passed the Beilun company’s acceptance, And has been well received by relevant parties. Later in Yangzhou Power Plant Phase II, Tianhuangping pumped storage power station,
