Transfer device, test system and test method

The invention relates to a transfer device which is used for an ultrahigh temperature impact test and comprises a transmission assembly, a driving assembly and a transfer channel, the transfer channel is connected between a high-temperature box and a low-temperature box and is provided with a heat insulation plate capable of closing or opening the transfer channel, and when the heat insulation plate opens the transfer channel, the driving assembly can drive the transmission assembly to move so that the transfer channel can be closed or opened. When the transfer channel is closed by the heat insulation plate, the heat insulation plate enables the high-temperature box and the low-temperature box not to be communicated with each other. According to the transfer device, the heat insulation plate is arranged for heat insulation, the requirement for high-low-temperature impact tests of the test samples is met, in addition, the transfer device replaces manual transfer of the test samples, on one hand, rapid transfer
