Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further。
Embodiment 1
As shown in accompanying drawing 1,2, in the mutual inductance type pipeline of the present embodiment, liquid metal monitoring device includes primary coil, secondary coil, sinusoidal alternating current source, signal reception and process system, shell, lead bushing and connecting terminal socket。
Adopt liquid metal monitoring device in the mutual inductance type pipeline of the present embodiment that the liquid sodium in certain liquid sodium vertical pipe is monitored, its main process is as follows: first, primary coil, secondary coil are wound on liquid sodium vertical pipe, connect sinusoidal alternating current source, signal reception and process system；Then, powering to primary coil in sinusoidal alternating current source, the signal of telecommunication that secondary coil produces is received by signal and process system receives and processes；Finally, judge whether to open liquid sodium conveying electromagnetic pump according to the data obtained and liquid sodium temperature。
Wherein, the principle of monitoring process is as follows: sinusoidal alternating current is producing alternating magnetic field B1 about by primary coil, and this alternating magnetic field B1 makes generation induction electromotive force in secondary coil。When having liquid sodium in monitored pipeline, the alternating magnetic field B1 that primary coil produces can make generation inductive loop in the liquid sodium in pipeline, this inductive loop can produce an alternating magnetic field Be contrary with alternating magnetic field B1, the alternating magnetic field B1 that primary coil produces is partially offset, thus making effective alternating magnetic field B less than alternating magnetic field B1, in the case, the induction electromotive force produced in secondary coil also reduces accordingly。Finally, received by signal and the induction electromotive force produced in secondary coil is processed by process system, it is achieved the monitoring of liquid sodium in pipeline。
