The invention discloses a buried substation which comprises a high-voltage cabinet, a transformer and a low-voltage cabinet, wherein the high-voltage cabinet and the transformer are embedded in an overall cement pit which is buried under the ground; a prefabricated slab covers the top of the cement pit; the low-voltage cabinet is arranged on the ground; a high-voltage connecting pipe is arranged between the high-voltage cabinet wire outlet tower of the high-voltage cabinet and the high-voltage wire inlet tower of the transformer; the joint of the high-voltage connecting pipe is in sealed connection through a connecting flange and a sealing gasket; the low-voltage wire outlet tower of the transformer is connected with the low-voltage cabinet on the ground through a low-voltage connecting pipe; an insulated waterproof material is poured in the low-voltage connecting pipe; and the wire inlet end of the high-voltage cabinet wire inlet tower of the high-voltage cabinet is provided with a connecting flange and a sealing gasket, and an external cable is led in the high-voltage cabinet wire inlet tower formed by pouring the insulated waterproof material to be in sealed connection. The buried substation has the advantages that occupied ground resources are few and the environmental attractive appearance is not influenced, and the attack of various sudden severe weathers can be borne.
Description
technical field [0001] The invention relates to a high-voltage power transformation equipment, in particular to an underground substation. Background technique [0002] Due to the special climatic conditions of coastal cities, typhoons and rainstorms occur from time to time, and the existing substations are usually built on the ground, which are easily damaged to varying degrees. Ability is a test. Moreover, in recent years, the weather conditions have gradually become harsh, and natural disasters such as heavy rain, floods, snow disasters, and typhoons have become more and more frequent. substation. Contents of the invention [0003] The technical scheme that the present invention solves its problem adopts is: [0004] An underground substation, including a high-voltage cabinet, a transformer and a low-voltage cabinet, characterized in that the high-voltage cabinet is a metal box with a fully welded and airtight structure, and a plurality of wiring towers made of insul...
