Lead wire junction box for overhead conductor insulation test

The invention provides a lead wire junction box for overhead conductor insulation test, which comprises a lead wire. The lead wire junction box is characterized in that the lead wire junction box further comprises an insulated wire box; the box body is provided with a stay wire hole; the box body is internally provided with an insulated horizontal wire reel; two ends of the horizontal wire reel are supported by two side walls of the wire box and penetrate through the side walls; one end of the horizontal wire reel is provided with an insulated rotating handle fixedly, and the other end is provided with an axial hole; the bottom of the axial hole is communicated with a radial hole; one end of the lead wire penetrates through the radial hole and the axial hole of the wire reel and is connected with an insulated measuring instrument, and the other end is wound on the wire reel and penetrates through the stay wire hole for being exposed to outside. According to the lead wire junction box, through using the insulated wire box and placing the lead wire in the insulated wire box, the insulated overhead state of the lead wire in the insulation test process can be realized, thereby performing a function of keeping high insulation safety, effectively ensuring personal safety of using personnel. Furthermore in wire coiling and uncoiling processes, a handle can be rotated for realizing quick wire coiling and uncoiling, thereby realizing simple and convenient operation.
