Abstract: The invention discloses a high-voltage disconnecting switch. A static end part, moving-end rotation disconnecting links, isolated conductive springs, a rotating pull sleeve, a moving-end copper link element, and a transmission unit are arranged, wherein the moving-end rotation disconnecting links, the isolated conductive springs, the rotating pull sleeve, the moving-end copper link element, and the transmission unit are arranged at a moving end part. Rotating directions of each pair of isolated conductive springs are opposite to each other; and electric compensation force enhancement units arearranged in the isolated conductive springs. When the high-voltage disconnecting switch is in a closing state, a magnetic field is generated in each pair of isolated conductive springs; the intensityand uniformity of the self-generated magnetic field are improved by the electric compensation force enhancement units; electrodynamic compensation is carried out on the contact pressure of the main static contact by using the electromagnetic force generated by the self-generated magnetic field, so that a problem of insufficient contact pressure of the high-voltage disconnecting switch is solved;and thus a phenomenon of over heating of the contact parts of the moving and static contacts because of the large contact resistance value is avoided, so that the reliability and safety of the power supply system is improved.
