Description

Technical Field

[0001] This utility model relates to the field of substation equipment technology, and in particular to a prefabricated cabin for electromagnetic shielding and isolation arrangement of primary and secondary equipment. Background Technology

[0002] Prefabricated modular substations are substations that are prefabricated in a factory and installed on-site. They consist of prefabricated modules and various electrical components installed inside the modules. The various equipment of the substation are integrated and assembled in the factory and then configured in a container-like module. After the substation's foundation civil engineering work is completed, the modules are assembled on-site. This can significantly shorten the construction cycle of the substation. Its compact design also greatly reduces the substation's footprint, resulting in significant economic benefits. It effectively solves the problems of traditional substations, such as large footprint, long construction period, and susceptibility to damage from external factors. Therefore, prefabricated modular substations are gradually gaining popularity.

[0003] Currently, in prefabricated substations, the primary and secondary equipment are typically installed in two prefabricated compartments for electromagnetic shielding, or in one prefabricated compartment without electromagnetic shielding. As a result, in existing prefabricated substations, the primary and secondary equipment are arranged in separate compartments or without electromagnetic shielding, leading to large footprints, complex construction, and secondary equipment being susceptible to interference.
