1、解讀高層建筑二級(jí)負(fù)荷消防設(shè)備設(shè)計(jì)Interpretation of the high-rise building fire equipment secondary loaddesign高層修建依據(jù)其運(yùn)用性質(zhì)、火災(zāi)風(fēng)險(xiǎn)司長(zhǎng)、分散和補(bǔ)救難度等進(jìn)行分類(lèi)。1O18層住所應(yīng)屬二類(lèi)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(jí)負(fù)荷，其消防用電負(fù)荷：消防操控室、火災(zāi)主動(dòng)報(bào)警及聯(lián)動(dòng)操控設(shè)備以及閥門(mén)等用電應(yīng)為二級(jí)負(fù)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(shè)置10(6)0.4kV戶內(nèi)變電所或在室外設(shè)置預(yù)裝式變電站。變壓器低壓側(cè)電壓為0.4kV時(shí)。單臺(tái)變壓器容量不宜大于1250kVA 預(yù)裝式變電站變壓器，單臺(tái)容量不宜大于800kYA。二級(jí)負(fù)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(tái)(兩臺(tái)變壓器可不在同一變電所)。當(dāng)線路自上一級(jí)配電所用電纜引來(lái)時(shí)有必要選用兩根電纜組成的電纜線路。其每根電纜應(yīng)能接受 100的二級(jí)負(fù)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(shè)計(jì)規(guī)范(以下簡(jiǎn)稱(chēng)新民partition, unfavorable branch lines across the fire zone.高層修建二級(jí)負(fù)荷消防設(shè)備設(shè)計(jì)，二類(lèi)高層寓

7、居修建中火災(zāi)主動(dòng)報(bào)警維護(hù)目標(biāo)分級(jí)為二級(jí)，所以此類(lèi)修建物內(nèi)消防設(shè)備供電干線及分支干線，應(yīng)選用有機(jī)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(yīng)消防設(shè)備的線路，它們同在一個(gè)防火分區(qū)內(nèi)且線路較短，當(dāng)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(jí)降一類(lèi)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(jī)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(shè)時(shí)

10、可不穿導(dǎo)管維護(hù)，但應(yīng)采納與非消防用電電纜阻隔辦法；選用明敷、吊頂內(nèi)敷設(shè)或架空地板內(nèi)敷設(shè)時(shí)，應(yīng)穿金屬導(dǎo)管或封閉式金屬線槽維護(hù)，且維護(hù)管或線槽應(yīng)采納涂防火涂料等防火辦法：當(dāng)線路暗敷時(shí) 應(yīng) 穿金屬導(dǎo)管或難燃型剛性塑料導(dǎo)管維護(hù)鍋爐出渣機(jī)，并應(yīng)敷設(shè)在不焚燒布局內(nèi)，且維護(hù)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
