The invention discloses a phase examination method of a high-voltage cable intersecting interconnection system. The phase examination method comprises the steps that wire connection is conducted on the head section of a high-voltage cable by a detector; phase examination is conducted on the intersecting interconnection system from a first joint box of the high-voltage cable by the detector; phase examination is conducted on the intersecting interconnection system from a second joint box of the high-voltage cable by the detector; the steps are repeated until all the phase examination work of the intersecting interconnection system is completed. According to the phase examination method, an existing phase examination method for the high-voltage cable intersecting interconnection system is improved, and therefore the phase examination work can be rapidly and efficiently completed through a common universal meter and simple wire connection under the condition that no person is at the opposite end for cooperation.
