Two transmission line circuit 1A, 1B are adjacently positioned, and two transmission line circuits 2A, the 2B in loop of the same name 2 are also adjacently positioned.Although this arrangement
Form disclosure satisfy that general power supply reliability is required, but still have the shortcomings that under special circumstances to reduce power supply reliability：
(1) when high voltage distribution installation outlet power supply, power load distributing are uneven, such as left section of bus 3M, left section of bus 2M are load entirely, bus
Right section, right section bus 1M of 2M is power supply entirely, then its bus running manner is extremely dumb；(2) when bus-bar fault or the maintenance of same section
Or during the new loop of interval enlarging, loop of the same name must have a power failure, and reduce power supply reliability simultaneously.The reason for causing the problems referred to above exists
In：Loop of the same name is mounted in identical double-bus, transmission line circuit 1A, the 1B in such as loop of the same name be connected on right section of bus 1M and
On left section of bus 3M, and loop of the same name is arranged on two sections of different buses, such as transmission line circuit 1A is connected on right section of bus 1M
On left section of bus 3M, transmission line circuit 1B is connected on right section of bus 1M and bus 2M, just necessarily causes overhead transmission line scissors crossing,
Cause constructional difficulties and potential safety hazard is brought to operation, and increased construction investment.
