解決方案

 

進線開關采用JVM16-63C40/2P型帶隔離功能的3級限流型斷路器,分斷能力為10KA。
配出分支回路均具有1P+N斷路器功能,安全性好,適用TT和TN-S接地系統。
因進線開關對下級斷路器具有后備保護功能,各分支回路的實際分斷能力均大于6KA。

因進線開關對下級斷路器具有后備保護功能,各分支回路的實際分斷能力均大于6KA。
考慮家用電器數量比較多,選用2臺漏電保護斷路器和5臺1P+N斷路器配合,保護5個插座回路。
本方案經濟性好,總寬度為16模數,JVDB-AP118/S*配電箱。

主要的低壓配電系統:三級配電
低壓配電等級:
對于大的和中等規模的場地,一般采用三個配電等級的低壓供電系統給所有負荷供電。
1、由低壓總開關柜直接配電:
此類配電等級,電源接自公用中壓電網的一臺或多臺中壓/低壓變壓器供電至:
a、場地不同的區域如工廠的車間、工業廠房的生產區、辦公樓的各樓層;
b、工業生產用如空氣壓縮機,冷卻水單元的大容量負荷或辦公樓的空調,電梯等。
2、分配電柜:
用于配電給每個區域內的用電負荷。
3、終端配電柜:
用于供電給各種用電負荷。
