【 摘 要 】

A miniaturized electric-taking ring used in microcomputer relay protection device is designed in this paper, which can obtain electric energy from the measured circuit and provide stable power supply for the protection device. The test results show that the ring is suitable for microcomputer relay protection device, low cost, safe and stable, and solves the difficult problem of equipment power supply in box environments.
