螺栓接头历来在母线安装及检修工作量中占有较大的比重。通常认为:接触面就是实际的过流面,因而要求接头除边缘允许有一些间隙之外,其内部应严密接触,接触面愈大,接触电阻愈小。然而,事实是怎样的呢?当我们将两块经机加工的母线分别涂凡士林及粉笔的薄层螺接后再拆开检查时,发现实际的接触面仅分布在螺栓附近;更有甚者,GN_(10)—20/8000型隔离开关的额定电流
Bolt joints have always been in the bus installation and maintenance workload in a larger proportion. Generally believed that: the contact surface is the actual flow surface, which requires joints in addition to the edge allows some clearance, the inside should be in close contact with the contact surface is larger, the contact resistance is smaller. However, what happened? When we split the two processed busbars with thin layers of Vaseline and chalk respectively and found that the actual contact surfaces were only distributed around the bolts, , GN_ (10) -20/8000 type isolating switch rated current
