A prefabricated substation

Abstract

The invention relates to the technical field of power distribution, and discloses a pre-assembled type transformer substation. The pre-assembled type transformer substation comprises a mounting crossarm, a power distribution transformer, a high-voltage switch cabinet and a comprehensive intelligent power distribution box; the comprehensive intelligent power distribution box is positioned on the side surface of the power distribution transformer; a mounting mechanism is arranged between the adjacent end planes of the power distribution transformer and the high-voltage switch cabinet, and between the adjacent end planes of power distribution transformer and the comprehensive intelligent power distribution box; and a linking assembly used for driving the comprehensive intelligent power distribution box to move towards the direction of the power distribution transformer through gravity when the high-voltage switch cabinet declines is arranged between the high-voltage switch cabinet and the comprehensive intelligent power distribution box. Two driving assemblies are adopted to drive multiple threaded rods to rotate, so that the screw thread connection degree between the threaded ends at the two ends of the threaded rods and screw holes in the power distribution transformer, screw holes in the high-voltage switch cabinet and screw holes in the comprehensive intelligent power distribution box, the high-voltage switch cabinet can be mounted on the power distribution transformer quickly, and the comprehensive intelligent power distribution box is mounted on the power distribution transformer.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a prefabricated substation. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. [0003] At present, the authorized announcement number is CN206313344U, and the authorized announcement date is July 7, 2017. The Chinese patent discloses a miniaturized prefabricated substation for urban use, including high-voltage switch cabinets, distribution transformers and comprehensive intelligent distribution boxes. The switchgear is installed on the distribution transformer; the comprehensive intelligent distribution box is located on the side of the distribution transformer and the high-voltage switchgear. There are transformer low-voltage bushings; transformer high-voltage bushings are plugged and connected with elbow joints. In this kind of miniaturized prefabric...

AI Technical Summary

Problems solved by technology

[0004] Because the integrated intelligent distribution box and the distribution transformer, between the high-voltage switchgear and the distribution transformer are connected and fixed by multiple bolts, and because the integrated intelligent distribution box, distribution transformer and high-voltage switchgear are all hoisted Lifting; at this time, in the process of fixing the bolts, multiple bolts need to be tightened with a wrench, which makes the installation process of the integrated intelligent distribution box, distribution transformer and high-voltage switchgear more cumbersome
