Description
technical field [0001] The invention belongs to the field of power systems, and relates to power equipment, in particular to an outdoor detachable high-protection box-type substation. Background technique [0002] Box-type substation, as an important power transmission equipment in the power system, is the guarantee for the normal transmission of the entire power grid; with the continuous development of the current economic construction, in order to meet the needs of various infrastructure and different users, more and more outdoor box-type substations should be put into operation However, although the appearance of outdoor box-type substations is more convenient for power grid transmission to a certain extent, the construction of outdoor box-type substations usually occupies part of the floor area. [0003] For this reason, in the prior art, a buried substation is provided, and the substation is arranged below the ground surface. Although this solves the problem of land occ...
