变压器 transformer

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。
Intelligent integrated substation selection of low-loss, oil-immersed, fully sealed S9, S10, S11 series transformers, can also use resin insulation or NOMEX
paper insulation dry type transformer, the bottom can be equipped with car, transformer can easily access.

高压侧 High pressure side

智能型一体化变电站高压一般采用负荷开关 - 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。
Intelligent integrated substation high voltage generally use the load switch - fuse combination of electrical protection, fuse one-phase fuse, the three-
phase linkage trip, load switch pressure gas, vacuum, sulfur hexafluoride and other types of optional power distribution Automatic operation, automatic
upgrade; fuse for the high-voltage current limiting fuses, with a striker, reliable action, breaking capacity, the main technical parameters in the table
below. For more than 800kVA transformer, can choose ZN12, ZN28, VS1 and other vacuum circuit breaker protection.

低压侧 Low pressure side
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。
Low-voltage side of the main switch using universal or intelligent circuit breaker, selective protection; outlet switch selection of new Molded Case switch
small size, short arcing, up to 30 loops; intelligent automatic tracking reactive power compensation device, And non-contact two switching methods for
users to choose.
