PORTABLE ULTRASONIC PARTIAL DISCHARGE MEASUREMENT DEVICE AND METHOD HAVING MANLESS AND AUTOMATIC SCAN FUNCTION

摘要

The present invention relates to a portable ultrasonic partial discharge measuring device with unmanned surveillance and automatic scan functions and a partial discharge measuring method using the same. More specifically, the device and the method of the present invention are capable of finding a partial discharge position by scanning the desired space of a measured object while moving a sensing unit using a gearing means. In other words, the device and the method of the present invention are capable of: scanning a certain area of a measured object by moving, in every directions, a ultrasonic sensor to measure a partial discharge in the measured object and a reflecting shade by using a gearing means such as a motor; and controlling a drive of the gearing means by a scan control unit. Therefore, the partial discharge in an electricity device can be automatically measured in the place where a worker can hardly measure directly as well as in an unmanned state. Furthermore, the device and the method enable the worker to aim to the position where a maximum signal is generated by automatically detecting the direction of the position where a partial discharge signal is generated and to acquire and store data and an image.
