Distributor

A distributor, comprising:

• a plurality of branch distribution lines to be connected to distributed loads via power packages, each of said power packages including a load switch and a transformer;
• branch units each including first and second main distribution switches in which output terminals of said first and second main distribution switches are coupled with each other to form output branch junctions which are coupled with said branch distribution lines, and first and second input junctions are coupled with input terminals of said branch unit at said first and second main distribution switches;
• and
• main distribution lines that emerge from a receiver switching apparatus toward said distributed loads and alternately concatenate said first and second input junctions of said first and second main distribution switches for each of said branch units in series.

A distributor, comprising:

• a plurality of branch distribution lines to be connected to distributed loads via load switches and transformers;
• a plurality of branch units each including first and second main distribution switches in which output ends of said branch units are coupled with supply terminals of said branch distribution lines and said output ends of said branch units are connected in parallel with one another;
• a first main distribution line that emerges from a receiver switching apparatus toward said distributed loads and sequentially concatenates first input ends of said branch units in said first main distribution switches connected on said branch distribution lines so that power distribution may be selectable provided to said distributed loads by said first main distribution line;
• and
• a second main distribution line that emerges from said receiver switching apparatus toward and sequentially concatenates second input ends of said branch units in said second main distribution switches so that power distribution may be selectably provided to said distributed loads by said second main distribution line.

• branch units each including first and second main distribution switches in which output ends of said first and second main distribution switches are coupled with each other to form output branch junctions which are coupled with said branch distribution lines, wherein first and second input junctions of each of said branch units are coupled with input ends of said branch units at said first and second main distribution switches;
• a first main distribution line that emerges from a receiver switching apparatus toward said distributed loads and concatenates said first input junctions in said branch units sequentially so that power distribution may be selectably provided to said distributed loads by said first main distribution line;
• and
• a second main distribution line that emerges from said receiver switching apparatus and concatenates said second input junctions in said branch units sequentially so that power distribution may be selectably provided to said distributed loads by said second main distribution line.
