Opening laboratory can not only motivate the initiative of students, but also play an important role in cultivating the students’ innovative ability. In view of the existing problem in electric professional experiment teaching, the necessity and possibility of opening laboratory is analyzed in electrical specialty teaching. With regard to the characteristics of electric specialty, multi-level open laboratory is established, which is based on experimental equipment, experimental time, experimental content and experimental subject. Laboratory opening explores the way to cultivate he students’ innovation ability, and promote experiment teaching reform. Finally, the open laboratory establishment results are introduced.
