High-voltage vacuum circuit breaker displacement detection device based on zigzag displacement sensor

The invention discloses a high-voltage vacuum circuit breaker displacement detection device based on a zigzag displacement sensor, relates to the field of high-voltage vacuum circuit breaker displacement detection, and aims to solve the problems of high cost and great influence of a strong electromagnetic environment in the prior art. The action of the high-voltage vacuum circuit breaker is transferred outwards to the zigzag displacement sensor by using the displacement conversion device, and the toothed plate of the zigzag displacement sensor is engaged through the closing action of the high-voltage vacuum circuit breaker, so that the optical fiber is deformed and the stress is changed, thereby increasing the power loss and causing the waveform change of the ring-down cavity. Therefore, the action of the high-voltage vacuum circuit breaker can be accurately and rapidly detected. Compared with other displacement measuring systems, the displacement measuring system is more stable and easy to operate by utilizi
