The invention relates to the technical field of insulation detection for high voltage equipment, in particular to an insulation detection method for a high voltage bushing based on frequency domain dielectric spectroscopy. The method comprises the step that a frequency domain dielectric spectroscopy based test is adopted to detect insulation of the bushing. With the adoption of the method, an influence of a Garton effect on measuring of tan delta at low voltage is avoided; a real tan delta frequency curve of the bushing at 0.001-1000Hz and at the low voltage is acquired and used for judging an insulation state of the bushing; and compared with the traditional bushing adopting a single 50Hz frequency point tan delta to judge the insulation state of the bushing, the judgment accuracy is improved. The test and a measuring device of the method are simple in structure and easy to operate, and the difficulty that the test and the device are difficult to operate when the measuring of the tan delta of the bushing is conducted at 0.001-1000Hz and at high voltage is solved.
