Abstract

The invention discloses a visual device detection method and instrument, and an application thereof in a smart grid. Wavelength tuning of a pulse is realized by adjusting a polarization controller, the obtained pulse is controlled by using an optical fiber phase array method, laser and an electric scanning mirror are synchronously controlled by a computer; then the surface of a detected device isscanned in a grid shape through a laser beam, recorded waveform data are displayed, a fault point and a discharge site in the device can be visually observed, whether the device is faulty is judged onsite, and maintenance and fault repair are performed in time, the problem that the existing detection instrument fails to perform onsite judgment in the fault detection is solved, the delay of the repair time of the device fault is avoided, and the situation of causing serious damage to the device is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric equipment testing instruments, and in particular relates to a visual equipment testing method and instrument and their application in smart grids. Background technique [0002] The company has 145 opening and closing stations, among which there are more than 1,000 station rooms in the community. Every year, the internal discharge phenomenon of the equipment in the station room is relatively prominent due to various reasons, and the number of damaged station rooms reaches 2 to 3. It is caused by complicated reasons. It is inevitable that the equipment in the station room will be damp. Due to the geographical location of the company, there are many open and close stations and underground station rooms. The space of the underground station room is limited, and normal ventilation cannot be carried out. The insulation reduction of long-term damp equipment also causes discharge failures. the main reaso...
