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.

    本发明公开了一种加热除霜静接点座,包括陶瓷底座,所述陶瓷底座的上端中心处固定连接有陶瓷外壳,所述陶瓷外壳的上端固定连接有接触片,所述接触片有三层结构组成且最中间为纯铜片,所述纯铜片的内侧即接触片与动触点接触的一侧等间隔固定连接有黄铜片,所述纯铜片的另一侧固定连接有记忆金属,所述记忆金属的下端与陶瓷外壳的上端固定连接,所述陶瓷外壳侧壁缠绕设置有热阻丝,所述陶瓷外壳的外侧设置有陶瓷护套,所述陶瓷护套的中下部设置有透气孔,所述陶瓷护套的内壁设置有反光涂层。本发明中,可以远程控制在特定的时间段内对静接点座进行热除霜的工作,同时采用记忆金属,可以使静接点座更加简单化。
