Abstract

DC60 (29/06/41) Substations of the "one and a half breaker" type have three identical (11,11 ', 11 ") air-tight chambers in a rectangular, parallel configuration. Where each chamber is equipped with one circuit breaker and two breaker switches, and each chamber with electrical inputs for the connection of an external busbar and / or cable trip switch. The input line will be Arranged not perpendicular to Through the upper surface of each room In the front row of the inlet line (27,27A, 27B) and in the parallel end row of the inlet line (27 ', 27'A, 27'B), the chamber (11,11 ") outside. end Two chambers have multiple inlet lines, one inward lead in one case and an inlet on the end In another case that has been made to fit for the connection. To each input cable in order Room (11 ') in the middle There will be one input line of each row that has been connected. By bus bar for Reconnect each other (35) to the inlet wires that make up a row of one of the adjacent chambers that have been fitted for connection to the two (11,11 ") side feeder cables. That room will be wired. Imported in a row That have been optimized for connection to both SPARs for interconnection and cables of substation feeder cables of type A "one and a half breaker" has three identical air inlet chambers. (11,11 '', 11 '') in the form of a parallelogram square. Where each room contains One circuit breaker and two breaker switches, and each room with an inlet wire for the connection of the exciter switch. With external busbars / and or cables The input line will be Lay it out perpendicular to pass through the upper surface of each room In the front row of the input line (27,27A, 27B) and in the parallel end row of the input line. (27 '', 27 '' A, 27 '' B) chambers (11,11 '') The outer end of the two chambers will have multiple inlet lines, a front inlet in one case, and an inlet on the end. In another case that has been made to fit for the connection. To each input cable in order of room (11 ''), in the center there is one row of input wires connected to each row. By busbars to connect each other (35) to the input lines that make up a row of one of the adjacent rooms. For connection to the two chamber feeders (11,11 "), there will be inlet wires in a row. That have been optimized for connection to both Bar for mutual connection And output cable of the feeder cable

Claims (1)

1. A substation in a medium voltage power distribution system that is built using so-called circuits. "One and a half breaker" is obtained by using a circuit breaker and Switch cut in the arrangement of cells that make the cables As two different output wires can be fed. From one and / or another of the feeder cable The two inputs and / or the lines run into the air. That substation Get the characteristic that Management of substation cells Will be made up of Tagged air-tight rooms:
