Three-dimensional array type circuit detection system and method for leakage of fused salt storage tank

Abstract

The invention discloses a three-dimensional array type circuit detection system and method for leakage of a fused salt storage tank, and belongs to the field of leakage detection and treatment of fused salt storage tanks of photo-thermal power stations. The three-dimensional array type circuit detection system comprises a three-dimensional array type wire group buried in a basic thermal insulation material of the fused salt storage tank, and the three-dimensional array type wire group is composed of transverse parallel wire groups and longitudinal parallel wire groups which are arranged at different height layers; each transverse wire and each longitudinal wire are connected with other components through connecting wires to form a detection circuit comprising a plurality of loops; and a direct-current power supply, a switch and a fixed-value resistor which are connected in series are arranged in each detection loop. The detection system further comprises a data acquisition device with a multi-channel acquisition function, the fixed value resistors connected with the transverse wires in all the loops are connected into different acquisition channels respectively, and the leakage position of the fused salt storage tank is positioned through channel electric signal changes caused by fused salt leakage. By using the three-dimensional array type circuit detection system and method disclosed by the invention, rapid detection and accurate positioning of the leakage of the fused salt storage tank are realized, so that huge economic loss caused by expansion of a leakage accident of the storage tank is avoided.
