摘要
针对尼尔基水利枢纽工程水电站厂高压变压器高压侧短路对系统各设备产生强大短路电流冲击而导致厂用变压器爆炸事故,阐述了高压限流保护装置设计原理、参数设计过程,认为该高压限流熔断器组合保护装置具有限流性、动作的快速性、可靠性,能够保证该系统电气设备安全稳定运行。
The design principle and the course of parameter design for high voltage current - limiting protection device were discussed focusing on the explosive accident of station - service transformer caused by a strong short- circuit impulse current produced by short- circuit of high voltage side of high voltage station -service transformer. It is believed that the device named as high voltage current - limiting fuse combination protection has many features such as current limiting, quick action, reliability, which can make electric equipment in the system operate safe and steady.
