矿用高压交流变频电传动负载特性试验装置设计∗

摘要

根据矿用高压变频电传动试验系统的技术设计任务，基于直接负载法，提出负载特性试验装置的一种设计方案，具有适应试品范围广、测试范围宽、响应快、精度高和自动化程度高等特点，同时也能完成变频器和电动机等单机试品的型式试验。%Combined with the technical design targets of test system and based on direct load method, this paper presents a design scheme of load characteristic test device, with the features of vast sample range, wide measurement range, fast response, high precision and high degree of automation. The test device can also complete the type test of variable-frequency drive and motor.
