The invention belongs to the technical field of mechanical fixation of reactor core vibration detectors, and particularly relates to a fixing device for installing a reactor core vibration detector and a fixing method thereof. The device comprises the reactor core vibration detector, a detector annular base, an upper assembly metal stand column, a right-angle connecting piece, a U-shaped connecting piece and a fixing bolt. According to the device, under the conditions that the shape of the fixed detector is not changed and the surface of the upper assembly metal stand column is not damaged, the upper assembly metal stand column is connected with the right-angle connecting piece of the fixing device through the U-shaped connecting piece, the manner that the detector is fixed to the right-angle connecting piece of the fixing device is adopted, and the installation problem after the displacement of the detector is effectively solved.
Description
technical field [0001] The invention belongs to the technical field of mechanical fixing of a core vibration detector, and in particular relates to a fixing device and a fixing method for installing a core vibration detector. Background technique [0002] Absolute displacement detector (hereinafter referred to as core vibration detector) provides the vertical low-frequency vibration signal of the reactor pressure vessel during the operation of the reactor at different power levels. Previously installed on the end faces of the four bolts on the main joint surface of the reactor pressure vessel, the sensor is fixed with a nut matching the bolt, and the low-frequency vibration signal is converted into an electrical signal through the principle of inductance. The core vibration detector is installed in the thermal shielding layer of the reactor pressure vessel. During the operation of the unit, the working environment temperature of the detector is close to 300°C, and the radiat...
