Novel alternating current and direct current standard shore connection box

Abstract

The invention discloses an alternating current and direct current shore connection box. The shore connection box comprises an installation beam, a pedestal, a box body and a box roof, wherein the boxbody and the box roof are located on the pedestal. An internal portion of the box body comprises electric appliance operation rooms and a cable room, a separation plate is arranged between the electric appliance operation rooms and the cable room, and the separation plate is used for installing electric appliance components. A bottom of the box body, a rear door of the box body and the box roof are designed to be a double-layer labyrinth ventilation structure. The alternating current and direct current shore connection box is a four-loop shore connection box. Two loops are used for alternatingcurrent power supply and the other two loops are used for direct current power supply. When the shore connection box is an alternating current power supply, each loop possesses one alternating current power connector socket. When the shore connection box is a direct current power supply, each loop possesses one anode direct current power connector socket and one cathode direct current power connector socket. By using the alternating current and direct current shore connection box, a ventilation and cooling requirement can be satisfied, and a high protection grade is possessed; and the shore connection box can provide the alternating current power supply and the direct current power supply.

Description

technical field [0001] The invention relates to a power supply guarantee device, in particular to a novel AC / DC standard shore power box installed in a port wharf. Background technique [0002] Usually, after a ship docks at a port, it is necessary to turn off the main engine and start its own auxiliary system to meet the power supply demand on the ship. However, most of the fuel for the auxiliary power supply system is heavy oil of poor quality, which will emit a large amount of pollutants after burning, which will have a serious impact on the environment around the port; moreover, the auxiliary power supply system will also emit noise, which will affect the residents and residents around the port. The work, life and rest of the crew on board. [0003] With the country's emphasis on port environmental protection and energy conservation and emission reduction, the use of shore power supply systems in ports has become a trend. The shore power supply system generally uses th...
