The invention discloses a critical performance test sample rod and device for a large-current multi-channel switchable switch type superconducting wire in a high background field, a current lead is divided into three sections, the bottommost section is a high-temperature superconducting current lead, and the current of the middle section can be detached, replaced or increased or decreased according to the performance and the number of test samples. The limiting groove extending in the radial direction is formed in the test sample plate, a plurality of samples can be placed in the limiting groove, and the limited space of the cylindrical Dewar is greatly utilized. And meanwhile, the power switch switching device can switch the current lead in a high-field environment without field reduction, so that the purpose of testing different samples is achieved. 本发明公开了一种高背景场中大电流多通道可切换开关式超导线材的临界性能测试样品杆及装置，电流引线分为三段，最底下一段为高温超导电流引线，中间一段电流可以根据测试样品性能和数量进行拆卸更换或者增减。测试样品板上开有沿径向方向延伸的限位槽，可放置多个样品，极大的利用了圆柱形杜瓦有限的空间。同时电源开关切换装置可在高场环境中切
