背景技术 Background technique
干式平波电抗器目前普遍采用避雷器放电计数器来监测避雷器放电动作次数，其结构由非线性电阻、电磁计数器和一些电子元件组成。当避雷器两端电压过高时，避雷器放电，电磁线圈吸合一次，再经过变换器把高电压隔离变换为可测的安全电压，然后传输给后台，如果变换器出现问题，就会导致高电压直接传给后台，造成危险。 At present, dry-type smoothing reactors generally use arrester discharge counters to monitor the number of arrester discharge operations, and its structure is composed of nonlinear resistors, electromagnetic counters and some electronic components. When the voltage at both ends of the arrester is too high, the arrester discharges, the electromagnetic coil pulls in once, and then the high voltage isolation is transformed into a measurable safe voltage through the converter, and then transmitted to the background. If there is a problem with the converter, it will cause high voltage Passed directly to the background, causing danger.
