Abstract

The present disclosure relates to a gas insulated switchgear (GIS), and more particularly, a structure of a bus in a GIS. A structure of a three-phase integrated bus in a GIS according to one exemplary embodiment, in a bus of a gas insulated switchgear comprising an enclosure (10), three phase conductors (30, 40, 50) inserted in the enclosure, and spacers coupled to both sides of the enclosure to fix the three phase conductors, is characterized in that the three phase conductors are arranged in a shape of inverted triangle, wherein a conductor (30) located at a lower side, of the three phase conductors, is formed in a shape of straight pipe, and has a branch bus (35) upwardly extending from its middle portion, and wherein each of two conductors (40, 50) located at an upper end of the inverted triangle, of the three phase conductors, has both side portions formed in a shape of straight pipe and a middle portion (42, 52) outwardly curved.

Description

technical field [0001] This specification relates to a gas insulated switchgear (GIS), and in particular to the structure of a three-phase integrated busbar in the GIS. Background technique [0002] A gas insulated switchgear (GIS) is an electrical device installed in a circuit between the source side and the load side of an electric power system so that when the circuit is artificially turned on or off under normal current flow conditions, or when When a fault current such as a ground circuit or a short circuit occurs on this circuit, it protects the power system and load equipment by safely cutting off the current. The GIS generally includes a bushing unit for receiving power from a high voltage power source, a line disconnector / earth switch (DS / ES), a gas circuit breaker, a busbar DS / ES, a drive unit, a controller, and the like. [0003] GIS takes up a lot of space. Therefore, an important design requirement of GIS is that each component is arranged compactly, exhibits ...
