Contact assembly for on-load tap changer

The invention discloses a contact assembly for an on-load tap changer, and the contact assembly comprises a static contact and a moving contact; the static contact is arranged in a fixed frame, two rotating frames rotating synchronously are arranged in the fixed frame, the moving contact is rotatably connected to a moving rod through a conductive slip ring, the moving rod is in static connection with a fixed rod, limiting plates for limiting the position of the moving contact are arranged on the two sides of the fixing rod, gaps are formed between the two sides of the limiting plates and the moving contact, elastic pieces are arranged in the gaps, the moving contact drives the rotating frames to rotate, when the rotating frames rotate, the static contact is away from the moving contact, and when the moving contact moves to the position between the two rotating frames, the static contact makes contact with the moving contact. According to the invention, the frictional force generated during the contact and sep
