Offshore power grid system transmission device and erection method thereof

Abstract

The invention relates to an offshore power grid system transmission device and an erection method thereof. The offshore power grid system transmission device comprises a roadbed region, an ocean region and transformation transmission towers, wherein the transformation transmission towers are arranged on the roadbed region, a transformer, a control cabinet and a cable connection end are sequentially arranged on the transformation transmission tower from top to bottom, the power grid system transmission device is characterized in that floating platforms are uniformly arranged in the ocean region, device boxes are arranged on the floating platforms, pressure power generation plates are arranged around the device boxes, and springs are arranged on the pressure power generation plates. The power grid system transmission device has the advantages of a transmission function, a plurality of devices can be connected and then connected with the power transmission towers on both sides when the power generation transmission platform is not convenient to erect and the power transmission platform is erected in a sea area with high erection cost, the platform and seabed are fixed by chains, and thus, the platform is prevented from excessively drifting out of a designated range.

Description

technical field [0001] The invention relates to a transmission device of an offshore power grid system and a realization method thereof, and belongs to the technical field of power grid erection. technical background [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network, or power grid for short. It includes three units of power transformation, power transmission and power distribution. The task of the power grid is to transmit and distribute electrical energy and to change the voltage. [0003] For example, the application number CN203278103U discloses a kind of electric power overhead line traction device. A guide line is set between the two poles with insulators installed, and a running car is hung on the guide line through a hook. The running car is equipped with wheels, and a storage battery and a controller are installed on the running car. The controller of the running c...

AI Technical Summary

Problems solved by technology

[0005] For the erection of offshore cables, there are currently two options: 1. Use offshore erection of transmission towers, which can be satisfied for short distances, but for long-distance deep seas, this method is difficult to construct, with long construction periods and high construction costs; 2. Submarine power 1. It is difficult to find the fault point of the communication cable, the construction cost is expensive, the fault repair cost is high, and it takes a long time
