Abstract

The invention discloses a "shared bushing" combined equipment and arrangement scheme on the HGIS busbar side, which is suitable for the optimal layout of the site of the HGIS power distribution device adopting double busbar connection. The circuit breaker double-row layout plan is adopted, and the busbar side bushings arranged on both sides of the busbar are combined and shared, so that a group of busbars connects two different compartments through the same group of busbar side bushings, and the circuit breakers and isolating switches of the two compartments pass through The low-lying trachea is connected to the two cannulae. For the suspended pipe bus and supporting pipe bus, the "shared bushing" joint equipment is arranged under the pipe bus, and the pipe bus is connected to the "shared bushing" joint equipment through two sets of bus down leads. The invention improves the integration degree of the HGIS equipment in the double-bus wiring mode, can reduce equipment investment; at the same time, it can reduce the lead wires on the pipe bus, and the outgoing wires are flexible; the occupied area of ​​the power distribution device can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of power system power transmission and transformation engineering design, in particular to a joint equipment configuration structure of "shared bushing" on the HGIS bus side, which is suitable for the site optimization layout of a 220kV HGIS power distribution device using double-bus connection. Background technique [0002] At present, the 220kV side of the 500kV substation in domestic power transformation projects mostly adopts the double-bus double-section wiring type, and the power distribution devices mainly include GIS (Gas Insulated Switchgear, gas insulated fully enclosed switchgear), HGIS (HybridGas Insulated Switchgear, composite switchgear) ), AIS (Air Insulated Switchgear, air insulated switchgear) three types. AIS power distribution equipment has low equipment investment, flexible operation mode, convenient disassembly and maintenance, and rich operation experience, but the power distribution eq...
