Adjustable circuit fault test device
The adjustable circuit fault assessment device conforms to the technical requirements and standards of the "electrical device project" of the relevant world technology competition. The test skills of Y-△ control circuit of full electric motor, forward reverse control circuit of three-phase asynchronous motor, lamp and socket control lighting circuit and other circuits are training content. Can realize value error, setting error, polarity/phase sequence (cross) error, short circuit, open circuit, high resistance, low insulation resistance and other fault types. The fault assessment device is divided into test surface and fault setting surface. The test surface is installed and arranged according to the industry construction standard; There is a corresponding control circuit diagram on the fault setting surface, and the line is connected by the way of quick connecting plug, so that the fault point can be set and restored quickly. Setting fault will not cause line loss, improve the service life of equipment, and achieve the maximum use of teaching and training equipment.
Specifications: length 950-1000mm* high 1500-1600mm* deep 450-500mm.
Structure: double door electric cabinet form, the device is provided with two front and rear operating surfaces respectively: test fault operating surface and setting fault operating surface; There are two modules: power circuit module and lighting circuit module, and they are installed independently. The dimensions are as follows: the operating surface of the power module is not less than 850mm* 800mm, and the operating surface of the lighting module is not less than 850mm* 400MMO
