Summary: | PURPOSE:To improve the extendability of necessary protective function and performance, by dividing processing function in relation to a protective relay, into a plurality of modules consisting of printed boards having the same shape, and by connecting the modules to each other via a general-purpose system bus. CONSTITUTION:Processing function in relation to a protective relay is composed of ten divided modules consisting of printed boards in the same shaped. These modules consists of an input transformer module 1 for an accident detecting relay, an accident detecting relay module 2, an input transformer module 3 for a main relay, a digital input/output and sequence processing module 4, an auxiliary relay module 5, a system control module 6, an A/D converting module 7 for the main relay, protective relay processing modules 8, 9, and a power module 10. The respective modules 1-10 are respectively connected to a general-purpose system bus B1. |
