Problems solved by technology

Due to the influence of various conditions, there is no practical solution for the emergency rescue of substations, especially when two or more adjacent substations are damaged at the same time.
When a major electrical failure occurs in a substation and needs to be cut off for maintenance, it will also bring great inconvenience to the normal railway transportation and affect the normal railway transportation

Embodiment Construction

[0008] The present invention is mainly composed of a flatbed truck 2, a low-voltage side 1, a transformer 3, and a high-voltage side 4 that are placed on the flatbed truck 2 and connected to each other in sequence from left to right.

[0009] HGISHalfGIS on the high-voltage side, that is, semi-GIS, adopts the existing comprehensive open and closed switchgear, and integrates circuit breakers, isolation / grounding switches, and CTs into one module on the basis of GIS combined electrical appliances, so that the probability of accidents will be extremely low The bus bar is arranged in the way of conventional AIS (open switch), and at the same time, it solves the shortcomings of the original conventional AIS equipment, such as large footprint, low reliability, and heavy maintenance workload.

[0010] The transformer is a 110kV single-phase traction transformer. The iron core adopts a single-phase single-column side-yoke structure, and the high-voltage bushing is arranged at the lower...

Abstract

A mobile traction substation belongs to the technical field of manufacturing technology of a special substation for an electrified railway. The mobile traction substation mainly comprises a platform vehicle (2), a low voltage side (1), a transformer (3), a high voltage side (4), etc, which are all arranged at the platform vehicle (2) sequentially from the left to the right and are connected with each other. The transformer is a single-phase traction transformer or a three-phase V / V connection traction transformer, a three-phase balance traction transformer or a three-phase YNd11 traction transformer and so on. The design of the whole structure is reasonable; the mobility is strong; the mobile traction substation can be operated in a short time; the power supply is reliable; the operation is flexible; the assembly is simple and convenient; and every component can also be transported alone. In normal times, the platform vehicle is in the state of maneuvering and awaiting transit; as soon as receiving a starting order, the platform vehicle is immediately ordered out; as soon as arriving at a substation, the platform vehicle can be operated immediately in one and a half hours. The platform vehicle can particularly meet the traction power supply needs of the traction supply system of railway electrification of 110kV and the traction supply system of railway electrification of 220kV under the conditions of combat readiness, natural disaster and failure.

Description

technical field [0001] The invention relates to a mobile traction substation, which belongs to the technical field of manufacturing special substations for electrified railways. Background technique [0002] At present, my country's railways generally have a substation about 50 kilometers away. The distribution of substations is wide and the number is large. Once wars, terrorist activities and serious natural disasters occur, the substations are easily damaged. The entire electrified line It will lose power and be paralyzed, and the transportation order will suffer catastrophic damage. Due to the influence of various conditions, there is no practical solution for the emergency rescue of substations, especially when two or more adjacent substations are destroyed at the same time. When a major electrical failure occurs in a substation and needs to be powered off for maintenance, it also brings great inconvenience to normal railway transportation and affects normal railway tran...
