JS7/放电计数器JS-7
JS-7放电计数器产品介绍（中文）
JS-7型放电计数器是一种用于记录避雷器动作次数的高压电气装置，串联在避雷器接地回路中，适用于35kV及以下电压等级的电力系统。该产品采用非线性电阻和电磁计数器为核心元件，通过避雷器放电时的能量触发计数机构，实现动作次数的准确记录。其结构设计采用不锈钢外壳与透明观察窗的组合，兼具密封性与可视性，能适应户内外多种环境条件（-40℃至+40℃）。计数器本体为两分体式结构，支持柜门或本体安装，RJ45接口通过网线连接，便于现场灵活部署。无源设计使其无需外接电源，内置电池可更换，STN点阵液晶屏轻触按键即可分相显示AB、AC等各相累计动作次数，长按按键可清零数据。产品主要用于监测过电压保护器及线路状态，通过分析异常动作预防事故，广泛应用于变电站、输配电系统等场景。11017
JS-7 Surge Counter Product Description (English)
The JS-7 Surge Counter is a high-voltage electrical device designed to record the operating次数 of surge arresters,串联 connected in the grounding circuit of arresters for 35kV and below voltage等级 systems. Its core components include non-linear resistors and an electromagnetic counting mechanism, which accurately captures discharge events by utilizing the energy generated during arrester operation. Featuring a stainless steel enclosure with transparent observation window, the device ensures both密封 reliability and visibility, suitable for indoor/outdoor environments (-40℃ to +40℃). The split-body design with RJ45 interface allows flexible installation on cabinet doors or arrester bodies via network cables. With passive operation (built-in replaceable battery) and STN dot-matrix LCD display, users can view cumulative counts per phase (AB, AC, etc.) with a single touch, while long-press enables data reset. Primarily used for monitoring overvoltage protectors and line conditions, it supports preventive maintenance through action analysis, widely applied in substations and power distribution networks.1613
