托克托电厂阻塞滤波器系统二次回路设计的改进

Improvement of Secondary Circuit Design Scheme for Block Filter in Tokto Power Plant

阻塞滤波器作为国内最近开始应用的一次设备,其设计、施工、安装、调试都会遇到许多新问题。介绍了托克托电厂阻塞滤波器系统二次回路设计特点,分析其断路器操作回路、刀闸操作回路、保护输入输出回路、监控系统回路、信号回路等的设计缺陷,提出正确的改进建议,排除了安全隐患,使得整套技术方案更加成熟可靠。

The block filter is a kind of primary equipment and comes to use recently in China, and there are a lot of troubles in the design, construction, installation and commissioning of this equipment. The design features of the secondary circuit for block filter system in Tokto power plant are presented; the design defects existing in its operating mechanism of circuit breaker, operating circuit of isolating-switch, input and output circuit of protection, monitoring circuit, signal circuit and so on are analyzed and correct suggestions are proposed, thus defects are remedies and potential safety hazards are removed, the modified technical scheme becomes more mature and reliable.
