Centralized switching cabinet used for intelligent substation analog sampling secondary equipment prefabricated cabinet

Abstract

The invention relates to a centralized switching cabinet for a prefabricated cabin of an analog quantity sampling secondary equipment of an intelligent substation, belonging to the technical field ofthe intelligent substation equipment. The centralized switching cabinet includes a DC empty area, afiber optic cable tracing area, a fiber optic cable adapting area, a cable tracing area and a cable adapting area. A DC empty open area and an optical cable transfer area are arranged on one side of that optical cable routing area, and are arranged on the upper part of the centralized switching cabinet body; The cable routing area and the cable adapter area are arranged side by side in the lower part of the centralized switching cabinet body; The optical cable tracing area and the cable tracing area are arranged crosswise on the upper part and the lower part of the centralized switching cabinet body; The cabinet body of the centralized switching cabinet is provided with a front door and a side door. The invention provides a centralized switching cabinet for a prefabricated cabin of an analog quantity sampling secondary equipment of an intelligent substation, which can solve the problems existing in the centralized switching cabinet of the prefabricated cabin of the analog quantity sampling secondary equipment of the intelligent substation in the prior art.

Description

technical field [0001] The invention belongs to the technical field of intelligent substation equipment, and in particular relates to a centralized transfer cabinet used for a prefabricated cabin of a secondary equipment for analog quantity sampling in an intelligent substation. Background technique [0002] At present, smart substations promote modular construction, and prefabricated cabin-type secondary equipment is the most important way of modular design. Prefabricated cabin-type secondary equipment consists of prefabricated secondary equipment cabins, cabin auxiliary equipment, and secondary equipment. It is composed of screen cabinets, secondary equipment, etc. The prefabricated centralized interface cabinet in the cabin is the bridge connecting the various devices in the cabin with the external devices. All cables outside the prefabricated cabin are routed through the centralized interface cabinet to achieve "factory prefabrication purpose of construction". Generally...

AI Technical Summary

Problems solved by technology

[0003] At present, the prefabricated cable adapter boards in centralized interface cabinets with many cables are usually arranged in the way of horizontal or vertical boards. However, due to the large number of prefabricated cables and the small spacing between prefabricated cable plugs, One of the prefabricated cable plugs is easy to accidentally touch the adjacent prefabricated cable plug during plugging and unplugging operations; the prefabricated cable connectors are arranged in several layers in the screen, and the distance between the outer cables after installation and wiring is too small to prevent the inner prefabricated cables from being connected. The installation and maintenance operation will bring a lot of trouble to the later operation and maintenance of the centralized interface cabinet. The layout of the vertical straight board will put a great test on the force of the aviation plug, which is not conducive to long-term operation; and the current cables and optical cables are generally divided into two parts. A transfer cabinet, a centralized transfer cabinet where individual optical cables are integrated, the optical cables are often mixed together, and "photoelectric separation" cannot be achieved, which is not conducive to the safe operation of equipment and subsequent maintenance
