Abstract

The present study aimed to find, through field tests, the dynamic response of a high voltage disconnect switch when exposed to forced vibration. A unidirectional motovibrator was used to generate harmonic vibration at three different frequencies and to measure the response through accelerometers and the displacement of the moving contact in relation to the fixed contact in the closing direction of the disconnector. Among the frequencies tested are 24 Hz, 34 Hz and 43,5 Hz, being the frequency of 34 Hz the one that best used the energy generated by the motovibrator, presenting positive results in closing, except for the excessive time to do so. The frequency of 43,5 Hz had the best performance for the correct closing of the disconnector, taking little time to complete closing, however the values of g force were high, which could jeopardize the structural integrity of the disconnector, in addition to the lower usage of the energy generated by the vibrator.
