A low-cost prefabricated cabin-type substation combined structure

Abstract

The invention discloses a combined structure of a prefabricated cabin type transformer substation with low cost. A prefabricated cabin is formed by the mutual tenon connection of a plurality of keel section structural beams; the keel section structural beams comprise keel section cross beams, keel section longitudinal beams, keel section vertical beams and bending arms; a plurality of keel section cross beams which are parallel to each other and a plurality of keel section longitudinal beams which are parallel to each other are connected to form a bottom structure of the prefabricated cabin in a tenoning way, and a plurality of keel section vertical beams are connected to a side wall structure of the prefabricated cabin formed by a bottom structure in a tenoning way; a side wall structure of the prefabricated cabin is provided with a plurality of tenoning structure connected with an adjacent prefabricated cabin; the bending beam is inserted above the two side wall structures of the prefabricated cabin, and a plurality of keel section cross beams are respectively connected to a top structure of the prefabricated cabin formed by the bending beam in a tenoning structure; the side wall structures are connected with composite surface wall plates, and a combined steel wire gauze and a protective panel can be utilized to reduce the thickness of the panel and greatly reduce the manufacturing cost of the transformer substation under the precondition of ensuring the impact strength of the composite surface wall plates.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a combination structure of low-cost prefabricated cabin type substations. Background technique [0002] At present, the traditional substation has the characteristics of complex layout, large floor area, long construction period and large amount of on-site construction. A small number of substations using GIS combined electrical technology have greatly improved their operational reliability and floor space. However, the cost is high and the later maintenance requirements are high. These substations are built according to fixed facilities. If the power supply demand is urgent and cannot be quickly responded to, once the power consumption environment changes, the workload of equipment removal or capacity increase, and a large number of non-reusable equipment will also cause investment waste. [0003] The prior art discloses a prefabricated cabin-type substation. The double-lay...

Problems solved by technology

It mainly uses assembled and connected prefabricated cabin-type boxes to build prefabricated cabin-type substations. It still does not have a modular combination design, which is not convenient for later assembly and maintenance, and the manufacturing cost is relatively high.
