High-voltage shore power centralized monitoring system

Abstract

The invention is specifically a high-voltage shore power centralized monitoring system. It also includes the shore-side shore power system located on the shore and the shore-side power connection equipment used to connect the ship-side power connection equipment. The power distribution cabinet, transformer, shore power access control panel are connected to the original ship switchboard; the high-voltage shore power centralized monitoring system is connected with a shore power intelligent monitoring system for monitoring system status and remote communication; ship side power connection equipment includes cables The winch and shore power closing interlocking mechanism, the cable winch and the shore power closing interlocking mechanism are arranged on the base; the shore power closing interlocking mechanism includes a body, which is provided with a toggle switch and a secondary protection mechanism. The beneficial effect of the present invention is that the ship power access and the shore power connection are uniformly controlled and the closing interlock is realized, thereby improving the operation efficiency and stability of the shore power connection, and simultaneously connecting the cable winch, ship power connection equipment and closing The gate interlock mechanism is integrated for management, which is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of shore power, in particular to a centralized monitoring system for high-voltage shore power. Background technique [0002] During the operation of the ship at the port, in order to maintain the needs of production and life, it is necessary to start the auxiliary generator on the ship to generate power to provide the necessary power, which will generate a large amount of harmful emissions. According to statistics, the carbon emissions generated by auxiliary generators during berthing of ships account for 40% to 70% of the total carbon emissions of the port, which is an important factor affecting the air quality of the port and the city where it is located. The shore power system of the ship means that when the ship is docked at the dock, it stops using the self-provided auxiliary generator on the ship, and instead uses land power to supply power to the main ship-borne system; at the same time, it should be ...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: the existing technology lacks the functions of real-time monitoring and remote communication and control of ship shore power data, which makes the user unable to understand the working status of the ship shore power system in real time, and needs to regulate or control the system When a safety failure occurs, immediate command or emergency response cannot be achieved; at the same time, the ship's side power connection equipment lacks effective implementation of cable connection management and shore power closing interlock, and the two cannot cooperate in a centralized manner, which increases the risk of equipment failure
