Background technology
Along with the growth at full speed of national economy, domestic extra-high-voltage alternating current electrical network enters the Large-scale programming construction period.The charge power of 1000kV extra-high voltage AC circuit unit length is very high, in order to limit power frequency and to avoid switching overvoltage, high-voltage shunt reactor (abbreviation high resistance) need to be set on long transmission line.
According to current ultra high voltage seismic Calculation scientific findings, in prior art, high resistance loop mainly adopts GIS sleeve pipe, lightning arrester, voltage transformer and four interconnective schemes of element of high resistance, wherein, GIS sleeve pipe place is that flexible conductor connects, lightning arrester is connected for pipe is female with voltage transformer place, high resistance, because body shakes, cannot adopt the female connection of pipe, but adopt flexible jumper gold utensil to connect.
But, plan that at present more extra-high-voltage alternating current transformer station is positioned at high seismic intensity area, the scheme that causes GIS sleeve pipe in prior art, lightning arrester, four elements of voltage transformer and high resistance to be connected is difficult to meet the requirement of antidetonation.According to seismic Calculation result, the pipe mother of same length, its support component is more, more favourable to antidetonation.And in the scheme that GIS sleeve pipe, lightning arrester, four elements of voltage transformer and high resistance are connected, GIS sleeve pipe is because self exists the problem on lead-in wire, should not be used for stay pipe mother, and lightning arrester and voltage transformer are for stay pipe mother, therefore, if can, by high resistance for stay pipe mother, can significantly improve the anti-seismic performance in this loop.
But conventional pipe capital tool is difficult to overcome high resistance and shakes the impact bringing, and cannot use herein.
