Abstract

The invention relates to a triangular GIS outgoing line layout structure for a voltage grade of 500kV and below. Compared with the prior art, the defect that the GIS outgoing line layout structure is relatively low in utilization rate of floor area is overcome. A B-phase tension insulator string is arranged at a line outlet side of an upper triangular beam; a B-phase inverted post insulator is arranged at the lower part of the upper triangular beam; an A-phase tension insulator string and a C-phase tension insulator string are arranged at the line outlet side of a lower triangular beam; a B-phase cross-arm insulator is arranged at one side, opposite to the line outlet side, of the lower triangular beam; and a center point between the suspension point of the A-phase tension insulator string and the suspension point of the C-phase tension insulator string corresponds to a fixed point of the B-phase cross-arm insulator. The lateral dimension of a power distribution device area is reduced, so that the length of a main bus-bar cylinder of GIS equipment is reduced; the equipment cost is reduced; and the floor area of the equipment is saved.

Description

technical field [0001] The invention relates to the technical field of power distribution device arrangement structure, in particular to a character-shaped GIS outlet arrangement structure for voltage levels of 500kV and below. Background technique [0002] According to different insulation types of equipment, substation power distribution devices can be divided into three types: GIS (GasInsulatedSwitchgear, gas-insulated fully enclosed switch), HGIS (HybridGasInsulatedSwitchgear, mixed gas-insulated switch), AIS (AisInsulatedSwitchgear, air-insulated switch), currently the most used The most important is the GIS and AIS power distribution device. With the continuous development of urban construction, saving the construction land of substation has become an important guiding ideology of design. GIS is currently the most integrated layout form of electrical equipment. It encapsulates busbars, circuit breakers, isolating switches, transformers, lightning arresters and other...
