RECIPROCATING SWITCHING MECHANISM HAVING ON-LOAD TAP CHANGER

Disclosed is a reciprocating switching mechanism of an on-load tap changer. The reciprocating switching mechanism of the on-load tap changer includes a connection assembly and at least one switching assembly. The at least one switching assembly includes two switching units, the two switching units are arranged on opposite sides of the connection assembly, the two switching units are connected with the connection assembly through a first connection rod and a second connection rod, the first connection rod and the second connection rod are separated by a preset distance, and the first connection rod is slidable relative to the connection assembly. Each of the switching units includes a movable contact assembly and two static contacts, the two static contacts are located at opposite sides of the movable contact assembly, the movable contact assembly is connectable to the static contacts, and the movable contact assembly is slidable relative to the static contacts. One end of each of the two static contacts is connectable with an external support, the movable contact assembly is connected with the connection assembly through the first connection rod and the second connection rod, and the movable contact assembly is rotatable around a central axis of the second connection rod.
