Problems solved by technology

[0004] The ship's AC power supply system usually adopts a three-phase three-wire system, which requires high power supply stability and continuity to ensure the reliability of the ship's power supply. Faults in the AC power supply system will affect normal operation and power supply to ships, especially the probability

Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0042] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0043] The invention provides a ship shore power system with the function of automatic fault removal, such as Figure 1-8 As shown, at least two power transmission three-phase lines are arranged in parallel. In this embodiment, two three-phase lines are connected in parallel to build a power supply network. The two power transmission three-phase lines are connected in parallel at the input end and the output end. The shore power of the present invention The system adopts two three-phase power supply lines connected in parallel. After one of the three-phase lines fails, it can be ...

Abstract

The invention discloses a ship-shore power system with the automatic fault removal function. The system includes at least two three-phase circuits arranged in parallel, a ground protection device, a plurality of fault acquisition unit, and a fault detection device; the neutral points of the three-phase circuits are provided with first electric signal acquisition units, parallel-connection lines atthe input ends of the three-phase circuits are provided with second electric signal acquisition units, the parallel-connection lines at the output ends of the three-phase circuits are provided with third electric signal acquisition units; the fault detection device includes a plurality of insulating electric contact ends, the inside space of the electric contact ends is provided with at least oneangular displacement ball grid ruler, the two ends of each angular displacement ball grid ruler are each rotatably provided with a selection detection unit, the selection detection units are limitedand rotatably arranged on the angular displacement ball grid rulers, and the bottoms of selection detection units are provided with reading heads with which the angular displacement ball grid rulers are rotatably sleeved. The ship-shore power system solves the technical problem that after the shore power system breaks down, normal operation of a transmission grid can not be guaranteed.

Description

technical field [0001] The present invention relates to a ship shore power system, more specifically, the present invention relates to a ship shore power system with the function of automatic fault removal. Background technique [0002] The method of using land power to supply power to berthing ships is called "shore power technology". When the ship berths at the wharf, all marine diesel power plants are stopped, and the ship's electricity is provided by shore power to reduce pollution in the port area. emissions. In 2006, the European Union proposed and passed the Act 2006 / 339 / EC on the use of shore power supply for ships berthing in various seaports within the EU, suggesting that member states propose preferential policies for the use of shore power and jointly formulate international standards for shore power. , should exchange experience on shore power supply with each other, and vigorously promote the use of shore power. [0003] In order to strengthen energy conserva...
