10kV配电变压器保护配置方式的比较及分析

The Comparison and Analysis of 10kV Transformer Protection Method

随着城网建设和改造的不断深入发展，负荷开关设备在12kV配电系统的环网供电和终端送电的应用也越来越多，选用负荷开关一熔断器组合电器作为变压器保护的合理性也已经被大家所认识。但负荷开关一熔断器组合电器的应用也有其局限性。因此在一些必须配置断路器作为保护的工程中，如何提供给用户一个安全可靠，性价比优越的方案，正是本文想要提出的观点。

By the development of the power network construction, the application of on-load switchgear were used more and more in the ring network power supply of 12 kV distribution system and terminal station. The rationality to select the on-load switch with fuse to protect transformer has already been dnown by everybody. But there is its limitation in on-load switch-Some project must dispose circuit breaker to protect transformer. How to offer user a safe and reliable scheme with economic cost performance in some project, this is exactly the view that this text wants to be put forward.
