| Zusammenfassung: | The utility model relates to a cable reel detection device. The cable reel detection device comprises a first interface, a second interface, a connecting piece and a detection circuit, the first interface is used for being connected with an electric input interface of a to-be-tested target cable reel; the second interface is used for being connected with an electric output interface of a target cable reel; the connecting piece is used for being connected with a metal shell of a target cable reel; and the detection circuit is connected with the first interface, the second interface and the connecting piece and is used for detecting whether a first electric transmission path of three-phase power between the electric input interface and the electric output interface, a ground wire of the electric input interface and a second electric transmission path between a ground wire of the electric output interface and the metal shell are well conducted or not.
