摘　　要：互感器负荷箱是使用互感器校验仪对互感器进行检定时常用的设备,起到模拟二次负荷的作用,目前一般采用负荷箱测试仪来对负荷箱进行校准。为确保该校准过程的规范性和准确性,需要保证负荷箱测试仪工作在较高的精准度上,因此作为计量器具,负荷箱测试仪同样需要定期进行检定。本文根据工作实践,提出了互感器负荷箱测试仪的误差校准方法以供探讨。Transformer load box is one kind of commonly used equipment when transformer calibrator is used to check transformer. It plays the role of secondary load simulation. Now the load box testing instrument is commonly used to calibrate the load box. To ensure that the calibration and accuracy specifications, testers need to ensure that the load box testing instrument works at a high accuracy. So as a measuring apparatus, the load box testing instrument also needs regular examination. Ac- cording to practice, the transformer load box testing instrument calibration methods are proposed for the study.
