摘　　要：空载及负载试验是变压器的例行试验。大型变压器空载及负载试验所需试验设备体积大质量重,试验设备需要被吊装、固定、运输、卸货、二次组装接线,这一过程存在一定的运输风险且效率较低。针对这一现场试验问题,采用SolidWorks设计空负载试验平台,将变频电源、中间变压器、互感器组、电容器组等试验设备集成两个试验车上,并通过重心分析、3D力学仿真、设备螺栓紧固方案设计,最后根据分析结果研制试验平台。该试验平台经过长途驾驶及现场试验,车载设备稳固无偏心无偏移问题,现场试验效率提高了3倍。No-load and load tests are routine tests for transformers.The test equipment required for no-load and load tests of large transformers is bulky and heavy,and the test equipment needs to be lifted,fixed,transported,unloaded,and reassembled and wired.This process has certain transportation risks and low efficiency.To solve this field test problem,this paper designed an No-load and load test platform by using SolidWorks,and integrated variable frequency power supply,intermediate transformer,instrument transformer set,capacitor set and other test equipment into two test vehicles.Through gravity center analysis,3D mechanical simulation,equipment bolt fastening scheme design,and finally developed the test platform according to the analysis results.After long-distance driving and field test,the on-board equipment is stable and has no eccentricity or deviation problem,and the field test efficiency is increased by 3 times.
