The removing partment of the switchgear may be assembled with vacuum circuit breaker and vacuum contactor etc. 標準和規(guī)范 Standards and specificationsKYN2812開關(guān)柜滿足IEC298，GB3906，DL404等標準。 Enclosure protection degree of switchgear is IP4X, protection degree is IP2X when the door of VCB room is open and the truck is be drew out.在系統(tǒng)的安裝和運行期間，要遵守所有相關(guān)的IEC規(guī)范及國家或地方相關(guān)的安全導(dǎo)則，還應(yīng)考慮江蘇長江電器股份有限公司提供的有關(guān)資料。CMaximum日平均值不大于 +35176。CMinimum (according to “minus 15 indoor class”)室內(nèi)環(huán)境濕度：Ambient humidity in room： 日平均相對濕度 95%及以下Daily average relative humidity less than 95%月平均相對濕度 90%及以下Monthly average relative humidity less than 90%安裝場所的海拔高度 1000m及以下Height above sea level at site less than 1000m地震烈度: 不超過8度Earthquake intensity: less than 8 degree沒有火災(zāi)、爆炸危險，沒有嚴重污穢及化學(xué)腐蝕的場所。制造廠與用戶應(yīng)就特殊工作條件取得一致意見。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)計上加以補償或限制載流量。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：Matters need attention：若開關(guān)柜運行地區(qū)的濕度較高，溫度波動速度較快且幅度較大，開關(guān)柜在這種氣候環(huán)境下運行，就有凝露的危險，因此開關(guān)柜在備用和運行狀態(tài)下，用戶應(yīng)保證加熱器全天侯投入！但在大電流運行中，可以不投入。KYN2812 has been considered with the problem of inside fault arc in switchgear on design. It is tested strictly according to GB3906 and IEC298, thus ensure effectively the safety of equipments and operation personnel.
