Embodiment

[0030] Such as figure 1 As shown, the power supply method for substation line interval replacement of 110kV / 3100A mobile high-voltage combined electric vehicle includes the following steps:

[0031] 1) The mobile high-voltage combined electrical vehicle is transported in place. Safely and stably transport the 110kV / 3100A mobile high-voltage combined electrical vehicle to the substation site where the transfer wire needs to be replaced, and park it at a suitable position on the side branch road of the substation line interval;

[0032] Such as figure 2 As shown, in this embodiment, the 110kV / 3100A mobile high-voltage combined electrical vehicle is parked on the left branch road of the line interval part to be replaced.

[0033] 2) State detection of mobile high-voltage combined electric vehicle. Carry out transportation evaluation on the entire transportation process of the 110kV / 3100A mobile high-voltage combined electrical vehicle, and judge whether it meets the condition...

Abstract

The invention relates to a mobile substation technology, and in particular relates to a substation line interval replacement power supply method for a 110kV / 3100A mobile high-voltage combination electric vehicle. The method comprises the following steps: in-place transportation of the mobile high-voltage combination electric vehicle, state detection of the mobile high-voltage combination electricvehicle, replacement of a patch cord by a line interval, communication set-up and debugging of the mobile high-voltage combination electric vehicle, monitoring parameter setting of the mobile high-voltage combination electric vehicle, and power supply and commissioning by replacement of the patch cord by the line interval. The power supply method is mainly used for transporting the mobile high-voltage combination electric vehicle to a substation when a substation line interval is overall overhauled or a main device fails; field alternative power supply and emergency rescue and disaster reliefcan be carried out; and thus, the power supply method has better practicability and reliability.

Description

technical field [0001] The invention belongs to the technical field of mobile substations, and in particular relates to a power supply method for substation line interval replacement of 110kV / 3100A mobile high-voltage combined electrical vehicles. Background technique [0002] Mobile substations with low voltage levels and small and medium capacity can no longer meet the requirements of modern urban power grids for emergency rescue and disaster relief, load transfer, overhaul of interval equipment, and short-term power consumption for power supply reliability. The mobile high-voltage combined electrical vehicle with small size and strong mobility has attracted more and more attention and attention from everyone. Among them, how the mobile high-voltage combined electrical vehicle can reliably and quickly carry the substation site to quickly replace the wiring and put it into operation after the disaster occurs is a key issue that needs to be solved urgently. [0003] At pres...
