A vehicle-mounted mobile substation

Abstract

A vehicle-mounted mobile substation, including a high-voltage incoming line unit, a horizontal transformer, a low-voltage power distribution unit, and a towing vehicle, is characterized in that the high-voltage incoming line unit, the transformer, and the low-voltage power distribution unit are all fixed on the base of the steel structure. 1. The low-voltage incoming line unit is located on both sides of the base, the transformer is located in the middle of the base, the bottom is equipped with a slide plate, the upper and lower sides of the base are provided with sealing plates, the middle is provided with reinforcing ribs, and the two ends of the base are provided with traction rings. The iron core in the transformer and the high-voltage line Coils and low-voltage coils are installed horizontally, upper and lower clamps are installed at the front and rear ends of the transformer, and longitudinal side pull screws are installed on the top of the transformer. The invention can be widely used in frequent mobile places such as emergency power consumption, temporary power consumption, maintenance power consumption, and mine and building power consumption, and has the advantages of complete equipment, complete functions, compact structure, fast and convenient movement, low-cost input and fast on-site connection characteristics of the operation.

Description

technical field [0001] The invention relates to a mobile substation, in particular to a vehicle-mounted mobile substation with matching equipment, complete functions, compact structure, fast and convenient movement, which is an improvement on the structure of the existing mobile substation and belongs to the technical field of power network equipment. Background technique [0002] In the middle of the last century, new products of mobile substations appeared in the United States, but their popularization and application were restricted due to heavy weight and large volume; at the end of the last century, due to the development and emergence of new technologies, new processes, and new materials, new products of mobile substations The weight and volume have been greatly reduced, and the manufacture and application of mobile substation products have developed rapidly. [0003] Mobile substation products are now gradually developing towards large capacity and higher voltage leve...

AI Technical Summary

Problems solved by technology

This kind of mobile substation is a new product developed by the applicant by introducing foreign technology. This new product has the same disadvantages as similar products in Europe and America: their hybrid insulation system is only limited to the mixture of solid insulation materials, and they are H-class insulation materials and B-class insulation materials. The mixed use of grade insulation materials, the heat resistance grade of H grade insulation materials is 180 ℃, the heat resistance grade of B grade insulation materials is 130 ℃, and the liquid insulation material uses transformer oil, which is also B grade insulation materials, because transformer oil is heat transfer cooling For conductors, the temperature difference between the highest and lowest temperature parts of the actual insulating material cannot be different by 50°C, and part of the reduction in volume and weight is at the expense of loss; due to the poor matching of heat resistance grades of materials in the hybrid insulation system, the volume and weight of the equipment, especially The transformer still adopts a vertical structure with a high center of gravity, which limits the speed of transportation and the stability of parking work.
