Abstract

The invention discloses a steam generator supporting plate edge corner monitoring and measuring system and method, and the system comprises a plurality of information collection devices which are respectively used for collecting the deformation quantity and temperature of a supporting plate at different measurement points, and each information collection device comprises a high-temperature-resistant micrometer which is used for collecting the deformation quantity of the supporting plate at one measurement point; at least one high-temperature-resistant temperature sensor which is used for collecting the temperature of the supporting plate at the measurement point; and a data transmission module which is used for transmitting the deformation quantity and temperature data acquired by the plurality of information acquisition devices to a terminal. The steam generator supporting plate edge corner monitoring and measuring system and measuring method can conveniently, efficiently and accurately monitor and measure the deformation of a nuclear power steam generator supporting plate, and adjust the air supply volume and the air supply direction of an external cooling system in real time through data detected by the monitoring and measuring system, and the deformation of the supporting plate is controlled within a tolerance requirement range.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a system and method for monitoring and measuring the edge corner of a support plate of a steam generator. Background technique [0002] When the AP1000 and CAP1400 nuclear power steam generators are subjected to local heat treatment of the middle ring seam and the lower head, the high temperature will cause the deformation of the support plate to produce DING, and the excessive heat deformation of the support plate will cause U-shaped tubes passing through the support plate. damaged. The measurement and monitoring of the support plate and the effective control of the deformation of the support plate are the problems that need to be solved urgently in the local heat treatment process of the middle annular seam and the lower head of the nuclear power steam generator. [0003] Due to the high temperature and confined space, personnel cannot enter and measure, so it is impossible to mon...
