Scope

Scope: This document specifies the functions and implementation conditions, technical requirements, component structure, lightning protection and grounding, primary access, secondary access, switch operation, testing and pre-grid connection inspection, operation and maintenance, and decommissioning of the 220kV mobile load transfer device. This document is applicable to the on-site use of 220kV load transfer devices in 220kV substations; Main technical content: The load transfer equipment project in substations involves HGIS, arresters, bushings, circuit breakers, transformers, DC systems, secondary systems, etc. However, there is currently no reference experience for load transfer using mobile load transfer equipment. This equipment has many components and a special structure, and is mainly applied to scenarios such as multiple interrupter bays being shut down simultaneously or completely in the 220kV side. Its operational reliability requirements are high, and the existing operation and maintenance measures for main electrical equipment are not targeted. To ensure the safe and stable operation of the transfer equipment, it is necessary to conduct pre- and post-transfer tests and monitoring on all levels of equipment, and to compile technical specifications for the on-site use of load transfer equipment after summarizing the test data.
