A wearable equipment is adapted for substation maintenance mobile inspection and includes a binding strap and a controlling wireless communication module. A thermal imager is disposed on one side of the binding strap. A prism display component and a voice interaction module are disposed on the other side of the binding strap. The thermal imager, the prism display component, and a microphone and a speaker of the voice interaction module are connected to the controlling wireless communication module through cables, to transmit information in a power system intranet. An application method includes mounting the wearable equipment to an electric power helmet, and automatically sending an infrared image, a visible light image, power monitoring information, voice, and a video in a power operation area to a background management controlling system for the substation maintenance mobile inspection.
