铁科院、通号公司、柳州局根据电气集中设备的特点及雷电防护的技术要求以及技术发展趋势,在电气集中设备雷电防护的系统中,研制了小型通用性强的防雷组合单元系列,具有防燃、防震、安装方便等优点。还研制了分线端子、防雷单元及测试三者合一的防雷分线柜,取代原有的分线盘。研制了大容量金属陶瓷五极放电管及工频380伏电源防护电路。填补了我国在这一领域的空白。该专题的防雷组合系列考虑了灯丝继电器的防雷电路,研究了地线设置,最大限度地减少信号设备的接地装置,起到等电位的
According to the characteristics of electrical centralized equipment and technical requirements for lightning protection as well as the technical development trend, the Iron Science Research Institute, Tonghao Co., Ltd. and Liuzhou Bureau developed a series of lightning-protection small-size universal units in the system of lightning protection for electrical centralized equipment. Flame retardant, shockproof, easy to install and so on. Also developed a sub-line terminals, lightning protection unit and test the three one of the lightning protection cabinet, substituting the original sub-line. Developed a large-capacity metal-ceramic five-pole discharge tube and frequency 380 volt power protection circuit. This has filled the gap in our field in this area. The topic of the lightning protection portfolio takes into account the filament relay lightning protection circuit, ground settings to minimize the grounding of signal equipment, play equipotential
