Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0050] Such as figure 1 As shown, the electrical protection method of the present invention establishes an electrical protection device for the shore power system, which mainly includes a shore power system 1 and a ship power system 2. The shore power system 1 and the ship power system 2 can be formed by plugging 3 sets of plugs and sockets into each other. Connected and linked circuits, when the ship needs to use land power to supply power to the ship, you only need to insert the 3 plugs included in the ship power system 2 into the 3 sockets included in the shore power system 1 to activate this function. Invented electrical protection device for shore power system.

Abstract

The invention discloses an electric protection method for a shore power system, which includes the following steps: (1) in the shore power system, a protection circuit which is connected and linked with a marine power system is arranged between the anode end and the cathode end of a shore power control power supply; (2) in the marine power system, a protection circuit which is connected and linked with the shore power system is arranged between the anode end and the cathode end of a marine power control power supply; (3) the shore power system is connected with the marine power system through plugs plugged in sockets to form a closed, linked system protection circuit. The method can realize the protection linkage between the shore power system and the marine power system, meet the requirement of the shore power system for electric protection quickness and guarantee the high safety and high reliability of the power supply of the shore power system, consequently, a land power supply can be adopted to supply power to shoreside ships, i.e. the usage of the shore power system can be increased, and the method achieves the effects of saving energy, reducing emission, reducing noise and increasing economic benefit, and has a broad application prospect.

Description

technical field [0001] The invention relates to an electrical component of a shore power system and a protection method for the system, belonging to the field of electrical technology. Background technique [0002] With the increasing degree of electrical automation of modern ships, ships are increasingly dependent on power supply. The high-safety and high-reliability ship power system has become one of the indispensable and important systems of modern ships. Provide high-quality power supply for ships under complex and changing working conditions. [0003] Generally, in order to ensure the safety and reliability of power supply when a ship is in port, fuel oil products (mostly heavy oil and diesel) are used to generate electricity to meet the ship's electricity demand. The combustion of heavy oil and diesel produces a large amount of sulfur compounds and nitrogen oxides, causing pollution to the surrounding environment. The noise generated by ships using diesel generator...
