Description
Technical Field

However, at the position of the overhead outgoing line of the GIS power distribution device, the space between three-phase outgoing line sleeves is increased suddenly compared with the core assembly of the GIS power distribution device due to the restriction of the inter-phase electrical safety distance of bare conductors, so that the width of a conventional horizontal outgoing line framework is larger, and the miniaturization advantage of the GIS power distribution device cannot be exerted.
Aiming at the problem, new technologies such as a double-fly wire outlet structure, a delta wire outlet structure and the like of an outdoor GIS power distribution device are proposed at the voltage level of 220kV and below, vertical space above the power distribution device is well utilized, wire outlet interval width is reduced, distribution device arrangement is more compact, and land utilization rate is effectively improved.
However, the 330kV voltage rating further increases the live distance requirement, having reached 18 meters in width per conventional horizontal outlet frame. The existing novel outgoing line structure forms have some limitations in the aspects of structural stability, maintenance convenience, frame width reduction degree and the like, so that the conventional horizontal outgoing line frame is still adopted at present for 330kV, the total width of the outgoing line frame is increased to be the primary limiting factor of the occupied area of the whole transformer substation under the condition of more outgoing lines, the corresponding land utilization rate is lower, and the method is not suitable for the development trend of transformer substation resource conservation.
