Abstract

The invention provides a substation. The substation includes a 110kV power distribution unit (10), a 110kV outgoing line (11), a 220kV power distribution unit (20), a 220kV outgoing and incoming line (21) and a transformer assembly, wherein transformer assembly includes a transformer body (31) and a protective shed (32) covered on the transformer body (31); the 220kV power distribution unit (20) is arranged between the 110kV power distribution unit (10) and the transformer assembly; the 110kV power distribution unit (10) and the 220kV power distribution unit (20) are both connected with the transformer body (31) through cables; the 220kV outgoing and incoming line (21) passes over the protective shed (32) and is connected with the 220kV power distribution unit (20); and a distance between the 220kV outgoing and incoming line (21) and the top of the protective shed (32) is larger than or equal to a safe distance. The substation of the invention has the advantages of small occupation area and cost-saving property.

Description

technical field [0001] The invention relates to the technical field of electric power transmission, in particular to a substation. Background technique [0002] figure 1 shows the structure of the 220kV substation in the prior art, such as figure 1 As shown, the substation includes 110kV power distribution device 10', 110kV outgoing line 11', 220kV power distribution device 20', 220kV incoming and outgoing line 21' and transformer assembly 30'. In order to ensure that 110kV outgoing line 11' and 220kV incoming and outgoing line 21' are 180°, the transformer assembly 30' is set between the 110kV power distribution device 10' and the 220kV power distribution device 20' and is close to the 110kV power distribution device 10'. A distance of more than 5m is reserved between the transformer assembly 30' and is used to make way for the hoisting vehicle for installation or maintenance. The above-mentioned substation occupies a large area and has high cost. Contents of the inven...
