Model meaning
First and second fusion standardized ring cage product introduction
The outer box of the metal material should be treated with anti-corrosion coating process, the coating is uniform and the thickness is consistent, the coating should have a firm adhesion to ensure that there can be no obvious rust spots in 20 years, and the box shell has an anti-sticker function.
The color of the ring cage is National network green, the CMYK value is C100M5Y50K40, and the PANTONG 3292C. If there are special requirements, it should be kept in harmony with the surrounding cultural and geographical environment. The surface of the case should have obvious reflective warning signs to ensure that the color will not fade for 15 years.
The outer box should be set up with obvious signs, such as the name of the equipment, electrical hazards, etc. Signs and signs shall be made in accordance with the provisions of GDW 742.
The distribution automation terminal in the ring cage includes centralized DTU and distributed DTU. Centralized DTU and distributed DTU shall meet their respective technical requirements. The outdoor ring cage reserved for the automation interface should also reserve an independent distribution automation unit installation space, which is generally placed according to the DTU shielded vertical, and the reserved width space is not less than 600mm. The DC power supply system is installed in the box, and secondary wiring is completed.
Primary and secondary fusion standardized ring cage metal material dimensions: 4 way: box width of 3200mm. 6 channels: The box width is 4000mm.
The ring cage depth is 1150mm. Height≤2300mm, non-metallic ring cage height≤2500mm. The door opening Angle is not less than 90°.
Overview
With the continuous development and progress of society, great changes have taken place in china's urban power grid, and most cities have formed or are forming a large number of load-intensive areas, in the past, the power supply from the substation 12kV line (or branch line) to the direct user has been difficult to meet the requirements of urban development. Therefore, a new power supply method is produced by opening and closing the power supply to the user. However, with the intensification of urban densification, some of the original civil openings have been restricted by land and urban planning, so a more advanced and practical outdoor high-pressure ring cage (standardized) has emerged. The product does not need civil construction and occupies a small area, the configuration is very flexible, the power supply is more reliable, the construction and installation, debugging time is greatly shortened, and the overall cost is reduced.
With the development of modern industry, the degree of automation and intelligence of electrical control equipment is getting higher and higher. the use of modern electronic technology, sensor technology, communication technology, computer network technology, the power equipment in the normal and accident conditions of monitoring, protection, control, measurement and other integration, to achieve good management, has become an inevitable trend and development direction.
Outdoor high pressure ring cage (standardized) is the use of foreign advanced technology, install and adjust 12kv switchgear, circuit breaker, load switch, current and voltage transformer, 12kv power supply PT, switching station FTU, RTU, communication control terminal (CCU), 12kv metering and automatic meter reading, USP power supply and indicating instrument into a movable, sealed and moisture-proof stainless steel box. Thus, the integration and modular assembly of the primary and secondary systems of the urban distribution network are realized, the construction period is shortened, and the reliability of the urban power network operation is greatly improved.
