Sail type multi-layer combined power distribution framework device

Technical Field

The utility model relates to a distribution framework technical field, concretely relates to power distribution framework device is united to sail formula multilayer.

Background

In recent years, with the rapid development of national economy, the power demand is rapidly increased, and with the expansion of cities, the planned land for building transformer substation engineering is more and more tense, the available land area is greatly reduced, and the 'bimorphism' becomes an important guiding idea in the design phase of power transmission and transformation engineering; in order to reasonably save the occupied land of the transformer substation engineering and improve the land utilization efficiency, the arrangement of transformer substation equipment can be optimized by combining lines, and a compact wire outlet mode is adopted; when urban and suburban transformer substation designs are faced with external conditions such as narrow site, crowded outgoing line corridor and the like, compact GIS combined electrical equipment is generally adopted to reduce the engineering occupation area; the GIS equipment is characterized in that a bus, a circuit breaker, a disconnecting switch, a mutual inductor, a lightning arrester and other elements are packaged in a grounded metal shell, and SF6 gas is filled in the metal shell to serve as an insulating and arc extinguishing medium, so that the longitudinal and transverse distances between the equipment are reduced.

In consideration of saving line investment, most transformer substations adopting GIS equipment still adopt overhead outgoing lines, and the outgoing line framework of the transformer substations generally adopts the scheme the same as that of the conventional AIS equipment, namely, three-phase conducting wires of the outgoing lines are horizontally arranged, so that the outgoing line interval width of the GIS power distribution device is still the same as that of the conventional AIS power distribution device, and the occupied area is larger.

Patent CN201821607804.8 discloses an outdoor GIS distribution device sail formula multilayer joint frame outlet structure of 330kV, when practical application, the fastness is not strong, and the risk that the building emptys is very big.
