DXK-12 箱式开闭所选型手册

DXK-12 Box Switch Station Selection Manual

1   概述Overview

户外箱式开闭所是新一代模块化、多功能组合、高可靠性、结构紧凑且免维护的环网开关设备，适用于 10KV 供电线路的环网供电或双辐射供电，亦可用于终端供电，对被供电的地区能起到电能的控制和保护作用。广泛应 用于供电负荷密度大，用电缆馈电网络的城市环网配电及大型工厂、居民小区。

户外箱式开闭所主要由 SF6 气体全绝缘全封闭紧凑型开关设备（C- GIS）或环保气体全绝缘全封闭紧凑型开关设备和金属（或非金属）外箱体组成，所有高压带电部分封闭在 SF6 气体或环保气体绝缘的不锈钢箱体内，按用户需要可按照进线单元、出线单元、计量单元、联络 单元、PT(电源)单元等排列自由组合，并可加载配电自动化系统，安装简单、通风良好、美观环保、无凝露问题、不受环境影响。

Outdoor box type open and close station is a new generation of modular, multi-functional combination, high reliability, compact structure and maintenation-free ring network switching equipment, suitable for 10KV power supply line ring network power supply or double radiation power supply, can also be used for terminal power supply, can play a power control and protection role in the area being supplied. It should be widely used in urban ring network distribution with high power supply load density and cable feed network, as well as in large factories and residential areas.

 

Outdoor cabinet by opening and closing is mainly composed of SF6 gas insulation all closed compact switchgear (C - GIS) or environmental gas fully insulated enclosed compact switch equipment and metal (or non-metal) of outside the enclosure, all closed high-voltage live part in SF6 gas or gas insulated stainless steel enclosure environmental protection, according to user needs can be according to contact line unit, qualification unit, measurement unit, unit, such as PT (power) units arranged free combination, and can load distribution automation system, installation is simple, well ventilated, beautiful environment, no condensation problems, is not affected by the environment.
