Title:
MUTUAL-INDUCTION TYPE LIQUID METAL LEAKAGE MONITORING APPARATUS AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/027542
Kind Code:
A1
Abstract:
Disclosed in the present invention are a mutual-inductance type liquid metal leakage monitoring apparatus and the use thereof. The mutual-induction type liquid metal leakage monitoring apparatus comprises a detection sensor used for being inserted into a leakage monitoring position. The detection sensor comprises a bendable tube body, a probe assembly arranged at one end portion of the tube body, and a cable passing through the internal portion of the tube body and connected to the probe assembly. The probe assembly comprises a protective sleeve connected to the tube body, a coil skeleton provided in the protective sleeve, and a primary coil and a secondary coil which are successively wound on the coil skeleton, joints of the primary coil and the secondary coil respectively penetrating through the coil skeleton and being connected to the cable. The mutual-inductance type liquid metal leakage monitoring apparatus of the present invention performs monitoring on the basis of the electromagnetic induction principle, and does not need to make contact with mediums under monitoring, thereby avoiding false triggering problems caused by impurity pollution, insulation aging, etc., and effectively reducing the false alarm rate. The mutual-inductance type liquid metal leakage monitoring apparatus of the present invention has the advantages of high reliability, high sensitivity, etc.
