Abstract

The invention provides an emergency power conversion system of a transformer substation. A mobile emergency power conversion device and a primary cable transferring device are timely dispatched to a designated position through a management center. After the mobile emergency power conversion device and the primary cable transferring device are dispatched to the designated position, a main transformer-mobile emergency power conversion device-primary cable transferring device-feeder line cable wiring loop can be formed quickly. By virtue of the wiring loop, an access preparation work can be madebefore a feeder line (user) is powered off, so that the outage influence on the feeder line (user) is reduced to the minimum. Therefore, the emergency power conversion system of the transformer substation can be quickly and effectively connected, the power failure time of the user is reduced, and the problems of difficulty in power failure, long construction period and wide power failure range caused by transformation of the transformer substation equipment are effectively solved.

Description

technical field [0001] The present application relates to the technical field of power supply and distribution, in particular to an emergency power transfer system of a substation. Background technique [0002] Facing the increasingly tight power demand, reliable and continuous power supply has become the top priority of every power company. With the rapid development of the national economy, the demand for power supply is further expanding, and the requirements for the reliability of power supply of substations are getting higher and higher. The original substation is also facing renewal and technological transformation. [0003] Some industrial parks require 24 hours of uninterrupted power supply throughout the year during the production process. Therefore, the transformation of substation equipment has brought problems such as difficulty in power outages, long construction period, and wide range of power outages. In order to better update substation equipment, a more i...
