摘　　要：为验证自取能无线测温装置的性能,笔者筛选了3种自取能无线测温装置,装配于模拟导电回路,按标准GB/T 11022—2011进行温升、额定短时耐受电流和额定峰值耐受电流的研究性试验,发现自取能无线测温装置在精度校验方法、传感器探头选择,自取能线圈铁心材料的选择、保护及控制回路设计方面存在着较大的改进及完善空间。According to China National Standard GB/T 11022—2011, the temperature rise tests, the short-time withstand current tests and the peak withstand current tests are carried out on three types of self-power supplied wireless temperature measurement devices from different suppliers in the simulation experiment circuit, to verify the performance of the devices. It is discovered that improvements are needed for the device in terms of the method of the accuracy verification, the selection of the sensor, the selection of the iron core material of the self power-supplied coil and the circuit of the control and protection.
