Outdoor prefabricated transformer substation

Abstract

The invention discloses an outdoor prefabricated transformer substation. By adopting a design idea of small-sized modularized prefabrication, the transformer substation is designed to be in a prefabricated assembled structure. The transformer substation comprises a civil engineering part and an electrical part. Mostly, the civil engineering part adopts prefabricated products, wherein the strip-shaped foundations of a container and a prefabricated cabinet, and the foundation of a transformer need to be prefabricated on site. Except the transformer, the electronic part adopts a container type module or a prefabricated cabinet type module, a wire inlet module adopts a box type gas insulated switchgear (GIS) module, the whole GIS module is mounted in the container or the prefabricated cabinet, the inlet wire adopts a cable, and the transformer is connected with the GIS module through an oil-gas bushing or an overhead wire. The on-site foundation prefabrication of the civil engineering part and the in-plant production debugging work of each functional module of the electrical part are simultaneously carried out, so that the construction period is greatly shortened. The outdoor prefabricated transformer substation is constructed by prefabricating and assembling modularized structures, breaks through the construction thought of a traditional transformer substation, and is high in efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of electric equipment, in particular to an outdoor prefabricated substation. 【Background technique】 [0002] With the rapid development of the national economy and society, the demand for electric energy is also increasing, and land and space resources are becoming more and more scarce. It is becoming more and more difficult to implement the substation site and line channel in the power grid planning. Power grid construction presents the characteristics of heavy tasks, high requirements, tight construction schedules, difficulties in land acquisition and policy handling, and the construction of substations is becoming more difficult. Due to the needs of rapid urbanization, industrialization and rapid economic development, power grid planning should be compatible with urban economy and development planning, and the progress of power grid construction should be compatible with national economic and social dev...

Problems solved by technology

The disadvantage of them is that from the substation feasibility study project approval to the completion and operation, each substation needs to go through complex processes such as design, bidding, on-site installation, and on-site commissioning.
