The utility model discloses a special-purpose tool for dismounting a static contact of a GW16 type disconnecting switch, comprising steel wire ropes and a control unit. One end of each steel wire rope is equipped with a clasp, and the other end of the steel wire rope is fixedly connected with the control unit; and the control unit comprises a handle crank, a control ratchet and a fixing pin, wherein the control ratchet is equipped with a lock catch; the clasp mainly fixes a steel-cored aluminum strand of the static contact; and the control ratchet combines structural principle of a hand wiring device with practical states of the steel-cored aluminum strand of the static contact, and is rotated to control telescoping of the steel wire ropes. During use, the steel-cored aluminum strand is first clamped by the clasp, the lock catch and fixing pin are adjusted to fix the control ratchet, and the steel-cored aluminum strand is further maintained in an original state, thereby effectively solving the problem of deformation of the steel-cored aluminum strand, improving safety performance of dismounting of the static contact of the disconnecting switch, improving working efficiency, and decreasing labor consumption.
