Abstract

The invention discloses a ship electric energy distribution control device based on contacts and a control method. The ship electric energy distribution control device mainly comprises a first contact, a second contact, a third contact, a fourth contact, an over-current relay, a first on-delay relay, a second on-delay relay and a third on-delay relay, wherein the components are correspondingly connected to form a main circuit and a control circuit of a ship power generator set. The ship electric energy distribution control device is simple in structure and low in cost. According to the control method, when the generation capacity of the ship power generator set is reduced, the control circuit of the ship power generator set enables corresponding contact coils to be electrified in sequence according to the importance degrees of loads, three types of loads can be started in the descending order of the importance degrees of the loads, at the same time, an over-current signal in the main circuit can be detected through the coil of the over-current relay, coils of corresponding contacts in the control circuit are subject to power loss, main contact heads of corresponding contacts of the main circuit can be turned into a normally opened state from a normally closed state, and corresponding loads can be cut off, so that reliable operation of important loads can be ensured.

Description

technical field [0001] The invention belongs to the technical field of ship control, and in particular relates to a contactor-based ship electric energy distribution control device and control method. Background technique [0002] The ship's power system plays an extremely important role on the ship. The continuity, reliability and quality of power supply of the power system will directly affect the economic indicators, technical indicators and vitality of the ship. The ship power system is mainly composed of power supply, power distribution device, power grid and electrical equipment. Currently the power source on ships is usually a generator set. Generator sets are mainly driven by prime movers such as steam engines, diesel engines, steam turbines and gas turbines to generate electricity. The power distribution device is used to receive the electric energy sent by the generating set, distribute the electric energy and control the electric energy. The cables connecting g...
