【正文】 witchgear is already airtight coating, the pressure gas will clash out the release of pressure plat. Adjacent switchgears are isolated by its self side board, after putting the switchgears together, air buffer layer exist yet, it may prevent the switchgears from pronging and melted by electric arc. Lowvoltage vault D is separate room with highpressure area. Clapboard space isolate the VCB vault B with cable vault C, even if VCB. truck is moved(here the valve is closed selfmotion),can prevent the operator from touching the electrification parts of bus bar vault A and cable vault C. releasing the tighten bolt, the level clapboard is removed, convenient for installation of cable seal terminal. Compartments in switchgear斷路器室（見(jiàn)附圖3/1，3/3，3/5，3/6）VCB vault (figure 3/1，3/3，3/5，3/6 showing)斷路器手車裝在有導(dǎo)軌的斷路器室B內(nèi)，可在運(yùn)行、試驗(yàn)/隔離兩個(gè)不同位置之間移動(dòng)。結(jié)構(gòu)細(xì)節(jié)和柜內(nèi)安裝設(shè)備，可見(jiàn)訂貨文件。If the humidity is higher on site, temperature fluctuations speed is rapidder and range is bigger, condensation phenomena will be appear for the switchgears running in this clime condition, so user should ensure that the heater running full time on spare and running condition! But running in highcurrent, the heater can stop. 2技術(shù)數(shù)據(jù) Technical data 開(kāi)關(guān)柜電氣參數(shù) Switchgear technical data額定電壓kV12額定絕緣水平1min工頻耐壓（有效值）kV42雷電沖擊耐壓（峰值）kV75額定頻率Hz50主母線額定電流A630,1250,1600，2000，2500，3150，4000分支母線額定電流A630，1250，1600，2000，2500，3150，4000*4秒熱穩(wěn)定電流（有效值）kA16，20，25，40**額定動(dòng)穩(wěn)定電流（峰值）***kA40，50，63，80，100Rated voltage kV12Rated powerfrequency withstand voltage(1min)kV42Rated lightening impulse withstand voltagekV75Rated frequencyHz50Rated main bus bar current A1600，1200，2500，3150，4000Rated branching bus bar currentA630，1250，1600，2000，2500，3150，4000*4s Shorttime withstand current（rms.）kA16，20，25，40Peak withstand current（peak.）kA40，50，63，80，100，125*需裝備通風(fēng)裝置 with forced ventilation.**40 kA為3秒 3 second for 40kA***儀用互感器的短路容量應(yīng)單獨(dú)考慮 The shortcircuit capability of transformer for measure should be considered by oneself. 耐內(nèi)部故障電弧性能 Performance bearing inside fault arcKYN2812開(kāi)關(guān)柜在設(shè)計(jì)上已考慮到開(kāi)關(guān)柜內(nèi)部故障電弧的問(wèn)題，根據(jù)GB3906和IEC298進(jìn)行了嚴(yán)格的試驗(yàn)，能有效地保證設(shè)備及操作人員的安全。CMaximum 24 hour average最低溫度 15176。公司保留對(duì)提供的數(shù)據(jù)和圖解的更改權(quán)力，需更改時(shí)，不另行通知。Ensure that installation，operation and maintenance are carried out by specialist electricians only.必須保證現(xiàn)場(chǎng)電氣設(shè)備的聯(lián)接條件和工作規(guī)程的適用和安全性。Pay special attention to the hazard notes in the instruction manual marked with this warning symbol.不要超出開(kāi)關(guān)設(shè)備在正常工作條件下的技術(shù)參數(shù)里規(guī)定的負(fù)載。KYN2812 metalclad enclosed switchgear is suitable for 3phase AC 50Hz/ single bus bar and single bus bar section electric power system.，with the function of “five preventions”.

It is advised to able to do that electric installation unit are charged with the foundation frame facture and building. It is agree with blueprint drew accord to manufactory requests to process the concrete project’s foundation frame.土建施工時(shí)開(kāi)關(guān)柜基礎(chǔ)標(biāo)高應(yīng)考慮預(yù)留基礎(chǔ)框架槽鋼的高度，并略有余量，見(jiàn)圖5
