解讀高層建筑二級負荷消防設備設計

1、解讀高層建筑二級負荷消防設備設計Interpretation of the high-rise building fire equipment secondary loaddesign高層修建依據(jù)其運用性質(zhì)、火災風險司長、分散和補救難度等進行分類。1O18層住所應屬二類高層修建。其間首要通道和樓梯間照明用電、客梯用電、排污泵和日子水泵用電為二級負荷，其消防用電負荷：消防操控室、火災主動報警及聯(lián)動操控設備以及閥門等用電應為二級負荷。High-rise building according to the use of nature, fire risk, director of classify,

2、 dispersion and remedial difficulty. 1 o 18 floors residence should belong to the category of high-rise building. During the primary channel and stair illume, passenger lift pump, sewage pump, and days for electricity utilization secondary load, and its fire load: active alarm and fire control room,

3、 fire linkage control equipment and valves, etc. Electricity should be the secondary load.高層住所宜在底層或地下一層設置10(6)0.4kV戶內(nèi)變電所或在室外設置預裝式變電站。變壓器低壓側(cè)電壓為0.4kV時。單臺變壓器容量不宜大于1250kVA 預裝式變電站變壓器，單臺容量不宜大于800kYA。二級負荷供電體系停電影響較大，宜由兩回路供電，供電變壓器也宜選兩臺(兩臺變壓器可不在同一變電所)。當線路自上一級配電所用電纜引來時有必要選用兩根電纜組成的電纜線路。其每根電纜應能接受 100的二級負荷。且互為熱備用

4、。High-rise residence should be set on the ground floor or underground 10 (6) / 0.4 kV indoor substation or in the outdoor setting preinstalled type transformer substation. When the voltage is 0.4 kV transformer low voltage side. Single transformer capacity should not be greater than 1250 kva preinst

5、alled type transformer substation, single capacity should not be greater than 800 kya. Secondary load influence on power system blackouts, and appropriate by the two circuits of power supply, power supply transformer and appropriate chooses two (two are not in the same substation transformer). When

6、used cable line from the upper level distribution cause it necessary to use two cables of cable line. The each cable should be able to accept 100% of the secondary load. And hot standby each other.JGJ162008民用修建電氣設計規(guī)范(以下簡稱新民partition, unfavorable branch lines across the fire zone.高層修建二級負荷消防設備設計，二類高層寓

7、居修建中火災主動報警維護目標分級為二級，所以此類修建物內(nèi)消防設備供電干線及分支干線，應選用有機絕緣耐火銅芯電力電纜，其分支線路和操控線路，系結(jié)尾雙電源切換箱放射式至相應消防設備的線路，它們同在一個防火分區(qū)內(nèi)且線路較短，當采納必定防火辦法如穿管暗敷防水板，宜選用與消防供電干線或分支干線耐火等級降一類的電線或電纜即阻燃型銅芯電線或電纜。High-rise building fire equipment secondary load design, second class upper walls built in alarm active fire maintenance target class

8、ification for level 2, so this kind of building material in fire equipment supply main and branch lines, should choose organic insulating refractory copper power cable, the branch circuit and control circuit, the radial end is double the power switch box to corresponding fire control equipment of th

9、e line, they present a fireproof partition and short circuit, when adopted must fire protection measures such as wearing dark apply, appropriate chooses and fire power supply main trunk or branch rated drop type of wire or cable that is flame retardant copper wire or cable.有機絕緣耐火銅芯電力電纜在電氣豎井內(nèi)或電纜溝內(nèi)敷設時

10、可不穿導管維護，但應采納與非消防用電電纜阻隔辦法；選用明敷、吊頂內(nèi)敷設或架空地板內(nèi)敷設時，應穿金屬導管或封閉式金屬線槽維護，且維護管或線槽應采納涂防火涂料等防火辦法：當線路暗敷時 應 穿金屬導管或難燃型剛性塑料導管維護鍋爐出渣機，并應敷設在不焚燒布局內(nèi)，且維護層厚度不小于30mm。Organic insulating refractory copper power cable or cable laying in the electrical shaft can not wear catheter maintenance, but should be adopted with the fire

11、 power cable cut off; Choose Ming fu, ceiling installation or overhead floor laying, should wear metal conduit or enclosed metal trough maintenance, and maintenance of fire retardant coating tube or slot should be adopted, such as fire prevention measures: when the line is dark apply. Should wear metal conduit
