The invention relates to a sleeve surface leakage current shielding tool and application thereof. The sleeve surface leakage current shielding tool comprises a drainage ring, a microammeter and a test instrument, wherein the drainage ring comprises a double-layer conductive retractable belt and a conductive spring; the conductive spring is arranged in the double-layer conductive retractable belt and is connected with the double-layer conductive retractable belt; the outside of the double-layer conductive retractable belt is provided with a wiring terminal; the wiring terminal is connected with the microammeter through a drainage wire; and the microammeter is also electrically connected with the test instrument. The shielding tool can be used for effectively leading out sleeve surface leakage current so as to prevent the sleeve surface leakage current from flowing into a test loop of the test instrument, prevent the surface leakage current from influencing the test data and mastering the real insulation status of the equipment to be tested. Meanwhile, the equipment can remotely receive data through Bluetooth so as to guarantee the operation safety of detection personnel, prevent the equipment to be tested from being damaged, save the site operation time and improve the working efficiency.
