Description

Technical Field

[0001] The utility model relates to the technical field of magnetostrictive displacement sensor calibration, in particular to a full-automatic calibration control device for a magnetostrictive displacement sensor. Background Art

[0002] The magnetostrictive displacement sensor is one of the important equipments required for the electrical equipment of the hydropower station. It is mainly used to monitor the displacement of the relay and the displacement of the main pressure regulating valve of the speed regulator. The guide vane displacement is one of the most basic and important parameters in the hydro-generator equipment. The guide vane opening can reflect the adjustment and operation conditions of the hydro-generator unit. The displacement sensor must work stably and reliably to ensure the safe operation of the hydro-power plant unit. If the guide vane opening and the main pressure regulating displacement have false alarms or no alarms, it will affect the frequent adjustment of the unit. In more serious cases, it will cause the unit to shut down, causing huge economic losses to the power plant. The accuracy and reliability of the displacement sensor are particularly important. Therefore, it is imperative to calibrate the sensor regularly. Utility Model Content
