Abstract

The invention discloses a high temperature gas cooled reactor outside fitted ball passing detection method and a system having a self-diagnostic function. The method comprises the followings: respectively arranging a first detection coil and a second detection coil at the upstream and the downstream on the outer side of a pipeline, conducting sine alternate current excitation on the detection coils to generate mutual inductance between the detection coils and a fuel ball, extracting voltage signals U1 and U2 from the detection coils through a resonance bridge detection circuit, processing U1 and U2 through a signal processor to obtain a ball passing wave signal U0, comparing the ball passing wave form U0and converting the ball passing wave form U0 into a wave peak pulse UP1 and a wave trough pulse UP2, judging by a singlechip whether the fuel ball passes by according to the U0, UP1 and UP2, monitoring whether the detection coils, the signal processor and the singlechip all normally work, and outputting the judging result that whether the fuel ball passes by when the detection coils, the signal processor and the singlechip all work normally, otherwise, sending a piece of warning information. According to the method and the system, the pipeline is not broken, the interference is resisted, an alarm is made when a fault occurs, and the result of counting the balls passing by is guaranteed to be accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to a high-temperature gas-cooled reactor external-mounted ball passing detection method and system with self-diagnosis function. Background technique [0002] A safe and efficient nuclear power reactor is one of the key technologies to solve energy problems. The pebble bed high-temperature gas-cooled reactor has been highly valued by many countries because of its high power generation efficiency, good inherent safety, and the ability to load and unload fuel without stopping the reactor. [0003] The basic principles of the fuel element detection devices currently used in pebble bed piles are all based on the influence of graphite conductors on the inductive reactance of coils to detect fuel elements. According to their different structures, they can be divided into the following types. One is the built-in type: the detection coil is pre-installed in the stai...
