The invention discloses a heating defrosting static contact seat which comprises a ceramic base, a ceramic shell is fixedly connected to the center of the upper end of the ceramic base, a contact piece is fixedly connected to the upper end of the ceramic shell, the contact piece is composed of three layers of structures, and a pure copper piece is arranged in the middle of the contact piece. Brass sheets are fixedly connected to the inner side of the pure copper sheet, namely the side, making contact with the movable contact, of the contact sheet at equal intervals, memory metal is fixedly connected to the other side of the pure copper sheet, the lower end of the memory metal is fixedly connected with the upper end of the ceramic shell, and a thermal resistance wire is wound around the side wall of the ceramic shell. A ceramic sheath is arranged on the outer side of the ceramic shell, air holes are formed in the lower middle portion of the ceramic sheath, and a reflective coating is arranged on the inner wall of the ceramic sheath. According to the heating defrosting static contact seat, the static contact seat can be remotely controlled to be subjected to thermal defrosting work in a specific time period, and meanwhile, the static contact seat can be more simplified by adopting memory metal.
