Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an electromagnetic tripping system equipment, including shell 1 and current conducting plate 2, 2 fixed connection in the inside left side of shell 1 of current conducting plate, the positive middle part top of shell 1 is through pivot fixedly connected with armature 3, the positive right side fixedly connected with yoke 6 of shell 1, the inside embedding of yoke 6 is provided with iron core 5, the one end outside nestification that yoke 6 was kept away from to iron core 5 is provided with coil 4, the positive below right side fixedly connected with bimetal 9 of shell 1, the positive middle part below fixedly connected with base 8 of shell 1, the left side of shell 1 is provided with junction box base 7.

Furthermore, the back surface of the conductive plate 2 is tightly attached to the outer side surface of the coil 4, the conductive plate 2 is used for communicating the whole circuit, stable magnetic force is generated after the coil 4 is electrified, when abnormal current fluctuation occurs in the circuit, the magnetic field of the coil 4 changes to complete attraction of the armature 3, the armature 3 moves to the iron core 5, tripping is completed, the whole circuit is instantly disconnected, and the circuit is protected.

Further, armature 3 sets up in the left side of iron core 5, and armature 3 sets up in the back of current conducting plate 2, can avoid when armature 3 is attracted to iron core 5 taking place the contact with current conducting plate 2 to ensure the accuracy and the continuity of action, it is safer.
