DXK-12 Box Switch Station Selection Manual

1   概述Overview

戶外箱式開閉所是新一代模塊化、多功能組合、高可靠性、結(jié)構(gòu)緊湊且免維護的環(huán)網(wǎng)開關(guān)設(shè)備，適用于 10KV 供電線路的環(huán)網(wǎng)供電或雙輻射供電，亦可用于終端供電，對被供電的地區(qū)能起到電能的控制和保護作用。廣泛應(yīng) 用于供電負荷密度大，用電纜饋電網(wǎng)絡(luò)的城市環(huán)網(wǎng)配電及大型工廠、居民小區(qū)。

戶外箱式開閉所主要由 SF6 氣體全絕緣全封閉緊湊型開關(guān)設(shè)備（C- GIS）或環(huán)保氣體全絕緣全封閉緊湊型開關(guān)設(shè)備和金屬（或非金屬）外箱體組成，所有高壓帶電部分封閉在 SF6 氣體或環(huán)保氣體絕緣的不銹鋼箱體內(nèi)，按用戶需要可按照進線單元、出線單元、計量單元、聯(lián)絡(luò) 單元、PT(電源)單元等排列自由組合，并可加載配電自動化系統(tǒng)，安裝簡單、通風(fēng)良好、美觀環(huán)保、無凝露問題、不受環(huán)境影響。

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.
