Switching apparatus for electrical power plant and transforming site

摘要

PURPOSE: A voltage switching switch for a substation and a power plant is provided to minimize stop of power supply to some sections of power supply lines due to breakdown of a power system and to stabilize the power system and the management system thereof. CONSTITUTION: The voltage switching switch executes supplying of power to two lines(A,B) selectively in power network. The logic circuit part switches to auxiliary connection terminals(a,b,c..) of the A line or B lines connected to a plurality of data output lines for remote control, state monitoring and database input in a central control station. The switching switch make it possible to select the auxiliary connection terminals(a,b,c) as driving motor depending on the signal values from the logic circuit automatically.
