Embodiment

[0021] In this embodiment, the present invention is further described by taking the application to 220kV indoor power distribution as an example.

[0022] Such as figure 2 As shown, the roof outlet structure of the indoor GIS equipment in this embodiment includes the "h" type outlet frame erected on the roof and the indoor GIS equipment located indoors on the roof outlet.

[0023] Such as figure 1 As shown, the "h" type outlet frame includes a first steel pipe pole 4 and a second steel pipe pole 5 erected on the roof, and the height of the first steel pipe pole 4 is greater than the height of the second steel pipe pole 5; A support cross bar 6 is arranged between the two steel pipe poles 5, and the first steel pipe pole 4, the second steel pipe pole 5 and the support cross bar 6 form an "h" type outlet frame body.

[0024] On the first steel pipe pole 4, an upper-level outlet cross-arm 1 and a middle-level outlet cross-arm 2 are arranged, and the upper-level outlet cross-ar...

Abstract

The invention discloses a roof outgoing line structure of indoor GIS equipment. An existing power distribution device of a 220kV substation, mentioned in the prior art, employs GIS equipment, two outgoing lines share a bridging framework, the framework width is 24 meters, the framework is arranged in a site of the power distribution device and is limited by the site, no enough site of the substation is used for achieving outgoing line scale in planning, so that the scale of the substation is limited, and the development of a power grid is limited. According to the technical scheme, the roof outgoing line structure of the indoor GIS equipment comprises an h-shaped outgoing line framework and roof outgoing line indoor GIS equipment, the h-shaped outgoing line framework comprises an upper-layer outgoing line cross arm, an intermediate-layer outgoing line cross arm, a lower-layer outgoing line cross arm, a first steel pipe rod, a second steel pie rod and a support horizontal rod, the roofoutgoing line indoor GIS equipment comprises the GIS equipment and a sleeve, the GIS equipment is arranged on indoor ground, and the sleeve is connected to an overhead outgoing line on a roof via an air pipe.

Description

technical field [0001] The invention designs an indoor GIS equipment roof outlet structure, which belongs to the field of electric equipment. Background technique [0002] With the continuous development of the power grid, make full use of the three-dimensional space of the substation, adopt the design concept of "space for plane", arrange the 220kV GIS power distribution device in the building, improve the overall space utilization of the substation, and realize the "functional area stacking" Let's set it up". According to the existing design concept and method, the 220kV power distribution device of the substation adopts GIS equipment, and the two outgoing lines share a single-span frame with a width of 24m. The scale of outgoing lines in the grid limits the scale of the substation and restricts the development of the power grid. Contents of the invention [0003] The technical problem to be solved by the present invention is: the existing substation 220kV power distri...
