The invention relates to the technical field of lightning arresters, and particularly discloses a temperature control material-based parallel gap action frequency calculation method, which comprises the following steps of: selecting a proper temperature control color-changing material, preparing the temperature control color-changing material into a color-changing material sleeve, and mounting the color-changing material sleeve on an upper arc guide arm of a multi-cavity parallel gap; and an image processing technology is adopted for regularly acquired device operation pictures, and a calculation method for the number of times of lightning impulse current flowing through the center is provided. According to the parallel gap action frequency calculation method based on the temperature control material, the actual action frequency of the parallel gap device when the parallel gap device is struck by lightning can be accurately obtained, and then the action state and the action frequency of the multi-cavity paral
