通过对国内外各种失超检测方法优缺点的比较,本文选取有源功率检测法来实现超导线圈的失超检测,并针对超导线圈电感值相等和电感值不等两种情况对有源功率失超检测电路进行了改进以及实验验证.结果表明,该失超检测方法能够及时准确的检测到失超信号,为超导线圈的失超保护提供了可靠的前提条件.
This paper choose partial active power detecting method to achieve quench detection of superconducting coils by comparing the advantages and disadvantages of quench detection methods at home and abroad.The improvement of partial active power quench detecting circuit is put forward and the experiment is carried out toward the inductance of superconducting coils is equal and not equal.The result shows that the quench detection method can timely and accurately detect the quench signal and provide the reliable precondition for quench protection of superconducting coils.
