The invention discloses a bidirectional automatic switching looped device which aims to solve the problems that for an existing bidirectional automatic switching looped device, a load switch or an earthing switch is arranged in the existing bidirectional automatic switching looped device, two separate single-loop switches are adopted to be combined to form either the bidirectional automatic switching load switch or the bidirectional automatic switching earthing switch, and according to the single-loop load switch or the earthing switch, a vacuum bubble arc extinguish chamber is put into a specified insulating box and arranged in a switch cabinet; through the structure, the occupied volume is large, installation is complex, too many production processes and parts are needed, consistency is low, and serious accidents are caused when the two single load switches are closed at the same time. According to the technical scheme, a looped network cabinet body, an operation mechanism, a load switch, an earthing operation mechanism and an earthing switch are included; the operation mechanism, the load switch, the earthing operation mechanism and the earthing switch are arranged in the looped network cabinet body; the operation mechanism is connected with the load switch, and the operation mechanism drives the load switch to be closed and opened; the earthing operation mechanism is connected with the earthing switch, and the earthing operation mechanism drives the earthing switch to be closed and opened.
