Abstract
An alternating current contactor (AC contactor) with an electronic short circuit self-locking function, includes an AC contactor body (a). The AC contactor body (a) includes a shell body. A short circuit self-locking portion is provided inside the shell body. The short circuit self-locking portion includes a current collecting unit (b) for collecting a current signal of phase lines (A, B, C); a short circuit detecting unit (c) for obtaining a voltage signal which characterizes a current signal, comparing with a reference signal, and outputting a short circuit detecting signal when short circuit occurs; a short circuit self-locking executing unit (d) for obtaining the short circuit detecting signal to trigger the AC contactor body (a) to generate and maintain a circuit-breaking action; and a self-locking releasing unit (e) for releasing self-locking of the AC contactor body (a) and resetting the alternating current contactor body (a).
