Switch network for electric energy transmission, has cascade module in which third and second connection points of first and last change-over switches are connected to preset connection points

摘要

The switch network has cascade module (KM) having change-over switches (WS1-WSn) having connection points (AP1-AP3) in which connection point (AP3) is connected to with either of connection points (AP1,AP2) depending on switch position. The voltage sources (Q1-Qn) are connected to connection points (AP1,AP2) of switches. The cascade module is connected to connection points (APM1,APM2) by connecting connection point (AP2) of one switch to the connection point (AP3) of next switch and connection points (APM1,APM2) to connection point (AP3,AP2) of switches (WS1,WSn) respectively.
