Abstract
The invention relates to an anti-rotation device of a vacuum circuit breaker hand-operated energy storage closing pressure spring. The anti-rotation device includes a closing guide rod which has a shaft shoulder. The closing guide rod is sleeved with the energy storage closing pressure spring and a closing sliding sleeve. The closing guide rod which extends out of the closing sliding sleeve is connected with an adjusting nut. The adjusting nut is arranged with a radial notch. The closing guide rod which extends out of the closing sliding sleeve is arranged with a first pinhole. An opening anti-rotation pin is penetratingly arranged inside the first pinhole. The two ends of the opening anti-rotation pin are embedded in the notch. The anti-rotation device adjusts the pressure of the energy storage closing pressure spring via the adjusting nut, and carries out a reliable positioning of the adjusting nut via the opening anti-rotation pin, thus preventing the deviation of an effective compression force of the energy storage closing pressure spring caused by the rotation of the adjusting nut, and guaranteeing the normal service lifetime of the hand-operated energy storage closing of the vacuum circuit breaker. The anti-rotation device is simple in structure, stable in function, and can conveniently adjust the energy storage pressure.
