Abstract

The invention relates to the technical field of substations, and provides a lead-in device applied to a distribution box in a substation, comprising a lead-in housing, a lead frame, a ventilation plate, a distribution box, a wire pressing assembly and a disassembly assembly. A first guide rail, a second guide rail, a first cavity, a conductive metal sheet and a second cavity are arranged inside the lead-in housing, and two of the second guide rails are symmetrically distributed on both sides of the first guide rail. The wire pressing assembly comprises an adjusting portion, a wire pressing portion and a bending rod. The adjusting portion comprises an adjusting block, an inclined groove, a first straight groove, a pressure cover, a special-shaped groove and a No. 1 spring. The wire pressing portion comprises a slider, a movable pin, a sliding tube, a sliding plate and a pressure block. The disassembly assembly comprises a limit block, a hollow rack, a No. 2 spring, a rotating rod, a knob and a transmission gear. A limit hole is arranged on the surface of the lead-in housing, the lead-in housing contacts the surface of the lead-in housing, the limit block is plugged and connected in the limit hole, and the lead-in housing has the characteristics of being easy to adjust the position of the lead-in housing and easy to disassemble and assemble the cable.
