Description

Technical Field

[0002] In the field of modern industrial production and electronic equipment manufacturing, current sensors, as a key detection component, are widely used in many industries such as power systems, industrial automation, new energy vehicles, smart grids, etc. The quality of their performance directly affects the stability, safety and reliability of the entire system. In today's context of rapid technological development, the performance requirements for current sensors are getting higher and higher. At the same time, manufacturers are also in urgent need of a detection tooling that can quickly, accurately and comprehensively detect the performance of current sensors and has good compatibility and versatility, so as to improve production efficiency, reduce production costs, and ensure that product quality meets strict industry standards and market demands.

[0003] As for the current traditional current transformer testing tooling, the current main testing method is to energize its pins and judge the quality of the current transformer by separately testing the voltages between multiple groups of pins. However, when the pins are connected to the power supply, the effective position that can be used to connect the testing equipment is extremely limited, which makes it difficult to accurately insert the testing probe. This not only reduces the detection efficiency, but may also affect the accuracy of the test results due to poor contact, making the detection process extremely inconvenient.
