摘　　要：针对如何有效及时地发现即将投入电网运行以及正在电网中运行的变压器所存在的绝缘缺陷,减少此类故障或事故的发生,避免变压器绝缘问题所导致的灾害,基于虚拟仪器技术平台设计了一种具有集成高压示波器、高速记录仪、脉冲峰值表等专用仪器仪表功能的标准变压器冲击试验测试系统,该系统装置具有强大的数值分析和记录功能。通过对所作的冲击试验研究结果分析,该试验装置能够及时发现变压器层间、匝间和主绝缘存在的绝缘缺陷,从而可以避免因变压器绝缘缺陷所带来的危害。A standard transformer impulse test system based on virtual instrmnent technique is proposed for detecting the insulation limitation of transformer in the usage or being about to enter electricity network effectively, and cut down such serious fault or accident. It is the key to avoid the disaster result from the insulation problem of transformer insulation test. The impulse test system has the capability of many appropriative instruments, such as high voltage oscillograph, high speed recorder and impulse peak-value instrument, etc. The results of transformer impulse experiment, show its validity and practicability to find insulation limitation between layer, circle, and main insulation of transformer, and avoid serious harm because of transformer insulation limitation.
