摘要
为提高电力用户用电信息采集系统的防雷击、防浪涌能力,采用分级保护设计思路和等电位技术,研制用电信息采集系统雷击浪涌防护装置。该装置包括浪涌吸收电路、信号放大电路和电源电路3个部分,具有安装简便快捷、接线方式灵活、防护作用优异且稳定、不需要接地等优点。现场应用验证该装置检测效果良好,保障了用电信息采集系统的可靠运行。
In order to improve the capability of lightning protection and surge prevention for the power consmnption information collection system, a lightning surge protection device is developed based on design idea of hierarchical protection and the equipotential technology. The device is composed by three parts： the surge absorption circuit,the signal amplifier and the power supply. It has the advantages of simple and quick installation,flexible connection,effective and reliable protection and free from grounding. The field tests show promising results. In real applications,it has greatly improved the reliability of the power consumption information collection system.
