Abstract
Provided are an insulation diagnosis and defect positioning method, apparatus and device for an insulated bus pipe, and a storage medium. The method includes: applying a test voltage between a ground electrode and a conductor portion of the insulated bus pipe; identifying multiple grounded segments of the insulated bus pipe according to a ground shielded short wiring and a line ground wiring, measuring a length of each grounded segment and a ground current of each grounded segment at the test voltage, and calculating a ground current per unit length of each grounded segment; comparing ground currents per unit length of different grounded segments; measuring a capacitance current value of each grounded segment according to a quantity, a length and a number of intermediate couplings included in each grounded segment; comparing the ground current and the capacitance current value of each grounded segment; according to the comparison results, diagnosing an insulation status and implementing defect positioning of the insulated bus pipe.
