Offshore box type safety substation

Abstract

The invention discloses a marine box type safety substation, and relates to the technical field of substation. The marine box type safety substation comprises a box body, a transformer, a low voltageswitch cabinet and a high voltage switch cabinet. The bottom of the box body is fixed with a support platform. The support platform is internally provided with a cooling oil tank, the inner wall of the box body is fixed with a heat absorption oil pipe, the outer surface of the box body is fixed with a heat dissipation oil pipe, an oil pump is arranged on the upper surface of the support platform,the oil inlet of the oil pump communicates with the cooling oil tank through a pipeline, and the oil outlet of the oil pump communicates with the cooling oil tank outside the box body through the pipeline, and a protection net is arranged on the peripheral side of the box body. The marine box type safety substation can use the sealing box body, the heat absorption oil pipe, the heat dissipation oil pipe and the oil pump to perform the circulating heat dissipation inside the box body, so that the internal temperature of the box body is consistent with the outside of the box body, and it is avoided that the internal temperature of the box body is too high to cause damaging of the internal devices.

Description

technical field [0001] The invention belongs to the technical field of substations, in particular to an offshore box-type safety substation. Background technique [0002] The offshore substation is an important part of the wind farm and plays an important role in the transmission of wind energy. When the offshore wind farm has a large capacity and is far away from the shore (more than 15 kilometers), it is generally necessary to build an offshore substation. The offshore substation is an offshore metal platform used to gather wind energy from offshore wind turbines, boost it to a high voltage level of 110kV or 220kV, and transmit it to the main power grid onshore through submarine cables. [0003] In order to solve the problem of salt spray corrosion on equipment, offshore substations often adopt a closed design, and arrange high-voltage equipment in a closed space, and the closed operating environment is in conflict with the ventilation and heat dissipation requirements of...
