SDKG-151 type high-voltage switch mechanical characteristic testing instrument instruction manual

SDKG-151 type switch characteristic testing instrument is a special instrument for detecting high-voltage circuit breaker mechanical dynamic characteristics. It can simultaneously measure the three-phase different phase, the same phase different phase, the moving contact stroke, the moving contact overtravel, the closing (opening) time, the closing (opening) bounce time, the just closing (opening) speed, the closing (opening) maximum speed and the closing (opening) average speed of three-phase six contacts.
