Abstract

The invention relates to a ship electricity fault current restrictor comprising a ship electricity system and a fault current restrictor. The ship electricity system comprises a power supply end and a load which are electrically connected with each other; and the fault current restrictor is a judging-type impedance device which is electrically connected with a patch from the power supply end to the load and can judge the fault current. A low-impedance state is presented if no fault current occurs and a high-impedance state is presented if the fault current is detected so as to restrict the fault current to pass through.

Description

technical field

[0001] The invention relates to a ship electric fault current limiting device, in particular to a device for limiting the short circuit fault current of the ship power system. Background technique

[0002] Due to the importance of the ocean to my country's industrial and economic development, the shipbuilding industry plays a pivotal role in the development of the ocean. For a ship, its power system is a very important part. The ship power system is somewhat different from the shore power system, and its reliability and stability requirements are more stringent. The stability of the power system of a ship sailing at sea is very important. For example, all navigation instruments, communication equipment, mechanical equipment, various pumps, compressors, blowers, centrifuges and domestic electricity on board need to rely on In the operation of electric power, if a generator or other electrical equipment fails, causing a partial or total power outage, serious ...
