特高压GIS主回路绝缘试验的电气量与试验能力计算方法
摘要：
本发明公开了一种特高压GIS主回路绝缘试验的电气量与试验能力计算方法。用于特高压GIS主回路绝缘试验的变频串联谐振装置试验能力估算方法，包括将变频串联谐振装置与特高压GIS设备串联连接；考虑变频串联谐振装置的容量限制，基于变频串联谐振装置的电流与特高压GIS设备的电容量关系，计算出变频串联谐振装置的第一试验能力范围；考虑特高压GIS设备的频率限制且基于变频串联谐振装置的谐振频率与特高压GIS设备的电容量关系，计算出变频串联谐振装置的第二试验能力范围；求取变频串联谐振装置的第一试验能力范围与第二试验能力范围的交集，得到变频串联谐振装置的实际试验能力范围。

The invention discloses an extra-high voltage GIS major loop insulation test electric quantity and test capability calculating method. A test capability estimation method of a frequency-conversion series resonance device used for an extra-high voltage GIS major loop insulation test comprises connecting the frequency-conversion series resonance device with an extra-high voltage GIS device in series; calculating a first test capability scope of the frequency-conversion series resonance device by taking regard of the capacity limitation of the frequency-conversion series resonance device and based on the relationship between the current through the frequency-conversion series resonance device and the electric quantity of the extra-high voltage GIS device; calculating a second test capability scope of the frequency-conversion series resonance device by taking regard of the frequency limitation of the extra-high voltage GIS device and based on the relationship between the resonant frequency of the frequency-conversion series resonance device and the electric quantity of the extra-high voltage GIS device; calculating the intersection set of the first test capability scope and the second test capability scope of the frequency-conversion series resonance device, and obtaining the actual test capability scope of the frequency-conversion series resonance device.
