用爆破压接修补断股导线,是借助于炸药爆炸时产生的大量气体形成的高压气团,使补修管产生塑性变形,将管内导线压实,达到修补导线的目的。爆破压接所用炸药有两种。一种是硝铵炸药,一种是导爆索。在带电的情况下,我们认为用导爆索缠绕法爆破压接施工方便,容易保证质量。在带电爆破压接时,由于雷管在强电场中,在很微小的泄漏电流时,会发生自爆现 Blasting crimping repaired broken wire, is the use of explosives produced by the explosion of a large number of high-pressure air gas group, the plastic deformation of the repair tube, the tube compaction of the wire to achieve the purpose of repair wire. There are two types of explosives used in burst crimping. One is ammonium nitrate explosives, one is detonating cord. In the case of electrification, we think that it is convenient and easy to ensure the quality by the blasting and crimping with the detonating cord winding method. In the live burst crimp, due to the detonator in a strong electric field, a very small leakage current, blew will occur
