型号及其含义
正常使用条件
1、海拔高度不超过1000m；2、环境温度：-25℃~+40℃；3、相对湿度：日平均值不大于95%，月平均值不大于90%；4、安装场所：无火灾、爆炸危险、导电尘、化学腐蚀性气体及剧烈震动的场所，若超出以上条件时，用户可与我公司协商。
高压侧
智能型一体化变电站高压一般采用负荷开关一熔断器组合电器保护，熔断器一相熔断后，三相联动脱扣，负荷开关有压气式、真空、六氟化硫等型式可选，可配电动操作机构，实现自动化升级；熔断器为高压限流熔断器，带撞击器，动作可靠，开断容量大，主要技术参数见下表。对于800kVA以上的变压器，可选用ZN12，ZN28，VS1等真空断路器保护.
低压侧
低压侧主开关采用万能式或智能型断路器，选择性保护：出线开关选用新型塑壳式开关体积小、飞弧短，最多可达30回路；智能型自动跟踪无功补偿装置，有接触器和无触点两种投切方式供用户选用.
变压器
智能型一体化变电站选用低损耗、油浸式、全密封S9.S10、S11系列变压器，也可选用树脂绝缘或NOMEX纸绝缘环保型干式变压器，底部可配有小车，变压器可方便地进出。
主要技术参数
变压器
1.本产品由高压配电装置、变压器及低压配电装置联接而成，分成三个功能隔室，即高压室、变压器室和低压室，高、低压室功能齐全，高压侧一次供电系统，可布置成环网供电、终端供电、双电源供电等多种供电方式，还可装设高压计量元件，满足高压计量的需求，
