摘　　要：针对目前在线校准交流电参量时,校准装置不易携带、现场校准工作效率不高的问题,研制一种新型在线测量交流电参量校准装置。该装置采用高稳定性负载电阻,利用风洞散热,通过多组负载的不同组合,可在(10～4500)W范围内连续稳定的调节出被校准功率值。经试验证明,校准装置稳定性好、易于携带、操作方便,可大大提高现场校准的工作效率。Aiming at the problem of online calibration of AC parameters, the calibration device is not easy to carry and the field calibration work is not efficient. A new online measurement AC parameter calibration device is developed. The device uses a high-stability load resistor,which uses the wind tunnel to dissipate heat. Through different combinations of multiple sets of loads, the calibrated power value can be continuously and stably adjusted in the range of( 10~4500) W. The test proves that the calibration device is stable, easy to carry and operate, and can greatly improve the work efficiency of the field calibration.
