智能切换技术在高压启备变应用的研究

Study on the Application of Intelligent Switch Technology in High Pressure Startup/Standby Transformer

大唐三门峡电力有限责任公司选用智能切换技术后可满足启备变冷备用状态下的快速切换,即正常运行方式下,启备变冷备用,在发电机故障时,跳开高厂变低压侧断路器后,直接合启备变高压侧断路器,经一短延时后合低启备变高压侧断路器。同时延长变压器寿命,每年节省维护费用。

Datang Sanmenxia Power Generation Co., Ltd. can realize quick switch under cold standby condition of startup/standby transformer after adopting intelligent switch technology, that is, under normal operation, startup/stand-by transformer is in cold standby condition, when the generator is in failure, and after it jumps high transformerlow voltage circuit breaker, directly collects high voltage circuit breaker of startup/standby transformer, and collects high voltage circuit breaker of low startup/standby transformer after a short delay.
