Special service conditions are to be agreed on by the manufacturer and user. l 已考慮安裝場(chǎng)所的海拔高于1000m時(shí)，空氣介質(zhì)強(qiáng)度的降低對(duì)絕緣水平的影響。Allow for the reduction in the dielectric strength of the air when site altitude is over 1000ml 若環(huán)境溫度超出極限值，在母線和分支母線的設(shè)計(jì)上加以補(bǔ)償或限制載流量。在柜內(nèi)安裝通風(fēng)裝置將有利于開關(guān)柜的散熱。If the ambient temperature is over top of the highpoint, must consider equalizing or limiting current capacity for the design of main bus bar and branching bus bar. Installation the aerator is favor of rejection of heat. 注意事項(xiàng)：Matters need attention：若開關(guān)柜運(yùn)行地區(qū)的濕度較高，溫度波動(dòng)速度較快且幅度較大，開關(guān)柜在這種氣候環(huán)境下運(yùn)行，就有凝露的危險(xiǎn)，因此開關(guān)柜在備用和運(yùn)行狀態(tài)下，用戶應(yīng)保證加熱器全天侯投入！但在大電流運(yùn)行中，可以不投入。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開關(guān)柜在設(shè)計(jì)上已考慮到開關(guān)柜內(nèi)部故障電弧的問題，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。KYN2812 has been considered with the problem of inside fault arc in switchgear on design.

The panel and main ponents can see in figure 3/ panel or outgoingline panel are diagram of basic switchgear panel，there are other derivative diagram，for example ,contact panel or metering panel .in addition，There are so many diagram of the switchgear panel with stationary type load switch、（SF6）VCB truck、VC truck、Disconnect truck. The panel has two maintenance modes. That is singleface maintenance and doubleface maintenance. The detail of structure and main ponents, can reference order document. Enclosure and clapboard開關(guān)柜的外殼和隔板由優(yōu)質(zhì)鋼板制成，具有很強(qiáng)的抗氧化、耐腐蝕功能，且剛度和機(jī)械強(qiáng)度比普通低碳鋼板高。三個(gè)高壓室的頂部都裝有壓力釋放板。出現(xiàn)內(nèi)部故障時(shí)，高壓室內(nèi)氣壓升高，由于柜門已可靠密封，高壓氣體將沖開壓力釋放板釋放出來。相鄰的開關(guān)柜由各自的側(cè)板隔開，拼柜后仍有空氣緩
