The utility model provides a static synchronous cascade compensation ware of compounding in series type, including transverter, series transformer and fixed skew compensation arrangement, transverter and series transformer insert among the transmission line in order, perhaps, the transverter is parallelly connected with series transformer's a side winding, among series transformer's the opposite side winding access transmission line, opposite side winding both ends parallelly connected have a the bypass switch, fixed skew compensation arrangement establish ties with the transverter or with the opposite side winding establish ties and to connect. Compared with the prior art, the utility model provides a pair of static synchronous cascade compensation ware of compounding in series type can show the required capacity of reduction transverter, practices thrift the cost, possesses the function of current -limiting simultaneously.
