Description

Technical Field

[0001] The utility model relates to the technical field of current measurement, in particular to a fully enclosed anti-interference Rogowski coil mutual inductor detection tool. Background Art

[0002] Under the current existing technology, the tooling structure designed for detecting Rogowski coil mutual inductor products is simple in design, the current connecting lines are staggered, the magnetic field interference is serious, the environment is not closed and isolated, and the completeness cannot be guaranteed. Due to human factors, environmental factors, and design errors of the tooling itself, the integrity and reliability of the test results will not reach the ideal state.

[0003] The details are as follows:

[0004] 1. Serious magnetic field interference: The test copper rods and conductive lines of the tooling have not taken any avoidance and protection measures in the environment. The lengths of the incoming and outgoing currents on both sides are different, resulting in greater magnetic field interference during the detection process, which has fatal uncertainty for product detection data.

[0005] 2. No outer frame protection: There are safety hazards in the connection between the portable current source and the tooling. There is no isolation protection design, and workers are prone to misoperation during operation.

[0006] 3. No limit during installation: The product has no limit during the installation process, which consumes a lot of time and results in substandard test data. Utility Model Content
