AI Technical Summary
In the current transformer testing process, workers are prone to mistesting or misclassifying defective products as good ones, resulting in low testing efficiency and unreliability.
Design a transformer error-proof testing device, including a test fixture and a test instrument. The device uses a probe module to contact the transformer pins and uses a fault indicator light to indicate defective products. Combined with a clamping unit and a drive unit, it ensures accurate contact and avoids false tests.
It improves the accuracy and efficiency of testing, avoids misclassifying defective products as good ones, ensures correct product classification, and enhances the reliability and automation of testing.
