Integrated photovoltaic prefabricated substation

Abstract

The invention discloses an integrated photovoltaic prefabricated substation which comprises a box body, a current transformer, a voltage transformer, a maintenance transformer and an oil tank, the current transformer, the voltage transformer and the maintenance transformer are installed in the oil tank, mineral oil is loaded in the oil tank, and the current transformer, the voltage transformer and the maintenance transformer are immersed in the mineral oil. The maintenance transformer and the main transformer are arranged into an integral structure, iron core modules of the maintenance transformer and the voltage transformer are omitted, and magnetoelectric conversion of the maintenance transformer and the voltage transformer module is achieved through magnetic field sharing of the main transformer (not shown in the figure). After the iron core modules of the maintenance transformer and the voltage transformer are canceled respectively, the power consumption of the maintenance transformer and the voltage transformer is greatly reduced.

Description

technical field [0001] The invention belongs to the field of prefabricated substations, and relates to an integrated photovoltaic prefabricated substation. Background technique [0002] Photovoltaic substations convert solar photovoltaic modules into electrical energy, which are connected to photovoltaic substations after aggregation, and then connected to the grid after DC to AC, low voltage and high voltage, and are uniformly deployed by the grid to supply power to users, gradually replacing fossil energy. However, at present, photovoltaic substations have The shortcomings of scattered units, redundant equipment, and large footprint increase the cost of photovoltaic substation construction, increase the difficulty of construction, and prolong the construction period of photovoltaic substations. The present invention effectively solves this problem. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the present invention provides an ...
