Elevator cable spark test device for preventing burr, dust and erroneous judgment

The invention discloses an elevator cable spark test device for preventing burr, dust and erroneous judgment. The elevator cable spark test device structurally comprises a warning light, a cover plate, a test box, a high-voltage erroneous judgment preventing device, a wire opening, a connecting rod, a testing machine and a controller. According to the elevator cable spark test device, liquid nitrogen is sprayed through a spray pipe, the low-temperature freezing effect of the liquid nitrogen is used for freezing and embrittling burrs on the surface of a flat cable in advance of a rubber sleeve,and then a scraping block is used for removing the embrittled burrs and dust on the surfaces of the burrs; then viscosity of oxidized gum on the surface of a dust removing guide wheel further removesthe dust, and the conditions that the burrs abrade the surfaces of bead chains, the dust enters bead chain gaps, and consequently abrasion is increased, a detection result is influenced and erroneousjudgment on a flat cable i
