Design Of Online Transformer Discharge Measurement System Based On Ultrasonic Technology

The power transformer is one of the most important electrical equipments in electrical power system; its running condition directly influences the security and economy of the electrical power system. The insulation damage is the main reason of transformer breakdown; partial discharge is the primary factor of the transformer interior insulation deterioration. This article researched in the transformer interior partial discharge on-line examination technology, analyzed each kind of measurment technique, solved the signal interference and the relatively slow data transmission problems. Online partial discharge detection method based on ultrasonic technology can be effectively determined the type of the partial discharge whether affect the normal operation of transformer through partial discharge and location of the point of discharge to.This paper narrated the entire shelf depreciation supersonic on-lineexamination system system design. Proposed uses the GPRS wireless network realization long-distance control and the correspondence, as well as uses GPS to realize different synchronized gathering to lay between damages the survey plan, and detailedly designs this system software. The successful development of the entire system of the power sector as a whole network monitoring system has seized the promotion of high value.
