AI Technical Summary
When high-voltage circuit breakers are in operation, vibration causes severe wear to the iron core inside the sensor, resulting in inaccurate detection results. Existing sensors cannot effectively solve the problem of uneven magnetic permeability, which affects the detection accuracy.
Design a high-low voltage signal conversion mutual inductance sensor. The rotating component drives the iron core to rotate around its own axis when moving axially. The gap between the iron core and the coil drum is set. Multiple sets of staggered ball bearings and spiral grooves are used to limit the axial displacement of the iron core. A sealing ring is used to prevent impurities from entering. Combined with a double elastic element buffer structure, it can adapt to the frequent operation of circuit breakers.
It improves the accuracy of micro-displacement detection, reduces detection deviations caused by core wear and magnetic inhomogeneity, ensures the accuracy of detection data and the service life of the equipment, and adapts to the harsh outdoor environment of the power grid.
