SWITCHGEAR OF UNILATERAL MAINTENANCE OF KSO-393-17 MB TYPE

摘要

A switchgear of unilateral maintenance comprises located in the upper part of the body collecting bars with a bus isolating switch, a vacuum switch installed horizontally under the bus isolating switch, current transformers located under the vacuum switch, overvoltage limiters installed opposite to the current transformers, and located in the low part of the body a line isolator and a zero-phase-sequence current transformer, a low-voltage section located on the body face. A bus isolating switch and the line isolator are located horizontally in such a way that divide the switchgear to collecting bars, equipment and cable compartments. Axes of rotation of switchgears’ controlled shafts are positioned perpendicular to body face. A vacuum switch basis is located along right side of the body, whereon current transformers are fixed. Voltage limiters are located on the left side of the body.
