Marine large-capacity main distribution board control screen

Abstract

The invention relates to a marine large-capacity main distribution board control screen. The marine large-capacity main distribution board control screen is characterized in that the interior of a cabinet body is divided into an upper part and a lower part through a metal partition plate. An instrument, a control panel and a control loop component are placed on the upper half part, and a busbar and a current transformer are arranged on the back portion of the lower half part of the cabinet body, wherein the busbar is placed on the lower back portion of the partition plate and is located in the middle of the whole cabinet body. A breaker and an external amphenol connector strip are installed on the front side of the lower half part of the cabinet body from top to bottom respectively, a door plate on the lower portion of the front side of the cabinet body and an upper cover plate and a lower cover plate on the back side of the cabinet body are provided with ventilation structures, and only a position, opposite to the busbar, on the metal partition plate between the upper half part and the lower half part is provided with a ventilation structure. The problems that large-capacity marine controlling devices cannot be installed due to the small installation space and are inconvenient to maintain are solved, the demands for electric and heat dissipation are combined, the space is utilized reasonably, and the maximum installation space is allocated. The marine large-capacity main distribution board control screen can be applied to ordinal marine electric power stations and can also be popularized and applied to other high-capacity power stations which are controlled complexly.

Description

technical field [0001] The invention relates to an electrical control panel, in particular to a large-capacity main switchboard control panel for ships. Background technique [0002] The traditional main switchboard is the center of the ship's power system. The functions of operation, control, protection, measurement and monitoring of the power generation and distribution of the entire ship's power system are concentrated on the main switchboard. The main switchboard is usually composed of Composed of generator control panel, parallel panel, load panel, etc. [0003] In principle, the structural type of the main switchboard adopts vertical, self-supporting, fixed panel type, usually made of steel plate into a box-type structure, and various switchgears, controllers, electrical measuring instruments, signal indicators and protective appliances are installed in the above it. The front and back of the main switchboard shall be equipped with solid insulating handrails so that ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the traditional main switchboard control panel is that the space utilization rate of the lower part and the rear of the instrument room is not high, and the capacity of the main switchboard is small. For the main switchboard of this ship, firstly, the power supply network is complicated and the control objects Complexity, and the high degree of automation of the main switchboard, resulting in a large number of control equipment can not be installed in the main switchboard, and secondly, the capacity of the main switchboard is large, and many technical performance indicators cannot be achieved with the traditional structure of the main switchboard. ensure

Therefore, in order to solve the situation that the control equipment cannot be installed and the technical performance indicators cannot be met, measures must be taken from the overall structural layout of the main switchboard
