Embodiment 2

[0028] Embodiment 2. The difference between embodiment 2 and embodiment 1 is that the medium voltage switchgears in the 10kV medium voltage switchgear module are arranged side by side along the vehicle width direction on the medium voltage distribution vehicle; The wide space of the tram makes the structure of the medium voltage distribution car more compact.

Abstract

The invention relates to a mobile substation in the substation field. The mobile substation comprises a high-voltage power transformation vehicle and a medium-voltage power distribution vehicle. The medium-voltage power distribution vehicle is equipped with a medium-voltage switchgear, secondary devices, secondary device accessories and a carrier for allowing the secondary devices / the secondary device accessories to be mounted. The medium-voltage power distribution vehicle is equipped with a prefabricated cabin. The medium-voltage switchgear, the secondary devices, the secondary device accessories and the carrier are arranged in the prefabricated cabin. The carrier is formed by secondary device mounting racks arranged in the prefabricated cabin; and the secondary device and the secondarydevice accessories are arranged up and down on the secondary device mounting racks. Compared with the prior art, the electrical components are arranged in the prefabricated cabin, so that the electrical components can be protected better, and integration degree of the medium-voltage power distribution vehicle is higher. Besides, the secondary devices in the prefabricated cabin are arranged vertically, so that height space of the prefabricated cabin is utilized fully, the volume of the prefabricated cabin is allowed to be more compact, and the medium-voltage power distribution vehicle is allowed to walk conveniently.

Description

technical field [0001] The invention relates to a mobile substation in the substation field. Background technique [0002] With the rapid development of domestic power grid construction, there are situations in some areas due to power shortage, substation maintenance, load transfer and temporary power supply, and there are also phenomena in some areas where the power grid system is not perfect and a large number of electrical equipment are outdated, which cannot meet sudden load growth. Demand and unexpected power outages caused by emergency failures, such as floods, snowstorms, earthquakes and other natural disasters. Conventional solutions—fixed substations cannot meet the above-mentioned emergency power supply urgency and flexibility requirements, and often cause long-term power outages in accident areas. [0003] Existing mobile substations include high-voltage substation cars and medium-voltage distribution cars. And secondary equipment accessories, secondary equipmen...
