Transformer high altitude test pincers, it includes insulator spindle, two forceps holder and installs the insulating clamp seat on the insulator spindle top, and the insulating clamp seat is for the support section by the two mutual disposition and be used for connecting the linkage segment that the two supported the section and be linked to be a whole U-shaped ducted body that constitutes mutually, is equipped with the banding opening of one on the inside wall of insulating clamp seat, and the open-ended both ends extend to the free tip that the two supported the section respectively, and the one end of two forceps holder stretches into and hinges at the corresponding free tip that supports the section from open-ended both ends respectively, and the two supports the middle part of section and respectively installs the torsional spring, and the middle part of linkage segment is equipped with the limiting plate, and the other end of two forceps holder is in the spring action of said torsional spring down respectively the abut against be equipped with the notch that the other end that supplies the two forceps holder moved on the lateral wall of insulating clamp seat in the corresponding side of limiting plate when the two forceps holder rotates. The utility model discloses only need one tester can directly operate subaerial, has not only promoted work efficiency, and does not have the safety risk.
