[0002] In power systems, circuit breakers are critical protective devices, and their performance is directly related to the safety and stability of the power system. To ensure the reliability of circuit breakers in actual operation, regular circuit breaker testing is essential. Speed testing is a major component of circuit breaker testing. During this process, the speed sensor must be aligned with the test position. To facilitate this, magnetic brackets are available on the market. However, magnetic brackets can move during testing, affecting test data. Furthermore, existing brackets on the market have limited adjustable speed sensor angles and are difficult to adjust.

[0003] Based on this, the utility model proposes a circuit breaker speed test sensor bracket, which can stably fix the speed sensor while quickly adjusting the speed sensor angle to improve the speed test efficiency. Utility Model Content
