Problems solved by technology

In my country, for a long time, due to the limitation of domestic management system and management concept, domestic research on this technology started relatively late.
In the past two years, some domestic manufacturers have designed and manufactured 110kV mobile substations for domestic use, but these mobile substations are faced with the fact that the layout of the internal 110kV combined electrical appliances and 110kV transformers on the same vehicle is too large, which cannot meet the domestic requirements. Passability of most roads in mountainous areas and cities
At present, the conventional solution to the above problems is to arrange the 110kV combined electrical appliances and 110kV transformers on one vehicle respectively, but this method will increase the number of vehicles used in the mobile substation, and the one-, The connection of various secondary cables is more cumbersome, which affects the on-site response speed of the mobile substation

Abstract

The invention relates to a compact fully enclosed mobile substation, the mobile substation includes a power distribution device, and the mobile substation includes a line transformer group composite combined electrical device connected to the power distribution device through a flexible cable; the combination The electrical device includes a trailer, and a line transformer group composite combined appliance which is arranged on the trailer and consists of a combined appliance and a transformer connected to the combined appliance. The mobile substation includes a line transformer group composite combined electrical vehicle and a power distribution vehicle, which can be flexibly combined or used independently, and both vehicles realize the high voltage enclosed in the electrical equipment, which effectively reduces the load on the mobile substation when it is put into operation at any time. The impact of the surrounding environment improves the safety and reliability of the mobile substation when it is used in unconventional occasions.

Description

Technical field: [0001] The invention relates to a mobile substation, more specifically to a compact fully enclosed mobile substation. Background technique: [0002] For a long time, my country has been adapting to the growth of power demand with continuously optimized service methods and a strong grid structure. However, the irregularity of power demand changes, the destruction of power facilities caused by natural disasters or human factors, and the necessary power outages in the process of power grid construction and transformation still affect the reliability of power supply to a certain extent. In order to solve the above problems, the temporary power supply contradiction is solved by establishing a temporary power supply, that is, a temporary mobile substation is built to quickly make up for regional and time-period power supply shortages without occupying actual land resources. Therefore, mobile substations are widely used in short-term capacity expansion, temporary ...
