高压侧  High voltage side

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QCE4, QCE2,QCE1 等真空断路器保护。

Intelligent integrated substations generally use a combination of load switch and fuse for high-voltage protection. After one phase of the fuse is fused, the three-phase linkage is tripped. The load switch is available in compressed air, vacuum, sulfur hexafluoride, and other types, and can be equipped with an electric operating mechanism to achieve automation upgrade; The fuse is a high-voltage current limiting fuse with an impactor, which is reliable in operation and has a large breaking capacity. The main technical parameters are shown in the table below. For transformers above 800kVA, vacuum circuit breakers such as QCE4, QCE2, and QCE1 can be used for protection.
