Hydro-generator air gap magnetic flux monitoring device

The utility model provides a hydro-generator air gap magnetic flux monitoring device, which comprises a stator and a rotor, and is characterized in that a plurality of circles of linear magnetic flux sensors are wound on a stator iron core from an inner circle to an outer circle at intervals, and each circle of linear magnetic flux sensor is fixed on the stator iron core through a plurality of fixing blocks; each circle of linear magnetic flux sensor is led out to be connected with a connecting line, and the connecting line is electrically connected with an external measuring element or a measuring terminal. The generator air-gap magnetic field is monitored through the linear magnetic flux sensor arranged on the inner circle of the stator core, and point monitoring in the prior art is improved into line monitoring through the arrangement of the multiple circles of linear magnetic flux sensors, so that the measurement range is increased, the accuracy of measurement data is improved, and a powerful guarantee is
