Estimation to Practicability of the Building Substation by Voltage 330 sQ with Three Power Transformers
It is installed that hooking two lines and two transformers at scheme distributing device by voltage 330 sQ «transformers - a buses with joining line through two breakers» and three installed transformer on substations brings about reduction of the factor to unavailability in 18,2 times in contrast with scheme with two transformers. At connection of the third transformer through two breakers factor to unavailability practically does not change.At connection one of the transformer through two breakers, at one-and-a-half-breaker scheme RU 330 sQ factor to unavailability falls in 6,6 times to scheme RU 330 sQ «transformers - a buses with joining line through two breakers» under three transformers.
