Drawings
Fig. 1 is a schematic circuit diagram of the present invention.
Detailed Description
As shown in fig. 1, the teaching aid for the detection experiment of the low-voltage circuit bonding point of the automobile comprises a teaching rack body, wherein a storage battery 1 is arranged on the teaching rack body, and the positive end of the storage battery 1 is connected with the negative end of the storage battery 1 sequentially through a first switch 3, a bulb 5 and an adjustable resistor 7; the adjustable resistor 7 is connected in parallel with a second switch 8.
In the teaching aid, the adjustable resistor 7 is used for simulating the virtual connection fault of the iron-bonding point, and the larger the resistance value is, the more serious the virtual connection is.
The positive end of the storage battery 1 is provided with a power supply positive electrode measuring point 2, the negative end is provided with a power supply negative electrode measuring point 9, one end of the bulb 5 is provided with a load power supply end measuring point 4, and the other end is provided with a load grounding end measuring point 6. During measurement, a 20V direct current gear is used by the universal meter, and the second switch 8 is in a normal state when closed.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
