The conductor connecting structure of the pole DPN leakage circuit breakers L shown in Fig. 3: flexible circuit conductor (111) is first welded on contact system
(333) on, conducting wire (555) is welded on terminal plate (444), is subsequently installed in pedestal (figure has omited) pole L space, flexible circuit conductor
(111) zero sequence transformer (222) passed through in being mounted in pedestal N extremely welds together with conducting wire (555) afterwards, uses wrapped with insulation
In the space of the pole pedestal N.The defect of this structure is --- repeatedly, conducting wire needs longer process line, replaces zero sequence transformer
(222) inconvenient, production efficiency is more low.
