JS7/放電計數(shù)器JS-7
JS-7放電計數(shù)器產(chǎn)品介紹（中文）
JS-7型放電計數(shù)器是一種用于記錄避雷器動作次數(shù)的高壓電氣裝置，串聯(lián)在避雷器接地回路中，適用于35kV及以下電壓等級的電力系統(tǒng)。該產(chǎn)品采用非線性電阻和電磁計數(shù)器為核心元件，通過避雷器放電時的能量觸發(fā)計數(shù)機構(gòu)，實現(xiàn)動作次數(shù)的準確記錄。其結(jié)構(gòu)設計采用不銹鋼外殼與透明觀察窗的組合，兼具密封性與可視性，能適應戶內(nèi)外多種環(huán)境條件（-40℃至+40℃）。計數(shù)器本體為兩分體式結(jié)構(gòu)，支持柜門或本體安裝，RJ45接口通過網(wǎng)線連接，便于現(xiàn)場靈活部署。無源設計使其無需外接電源，內(nèi)置電池可更換，STN點陣液晶屏輕觸按鍵即可分相顯示AB、AC等各相累計動作次數(shù)，長按按鍵可清零數(shù)據(jù)。產(chǎn)品主要用于監(jiān)測過電壓保護器及線路狀態(tài)，通過分析異常動作預防事故，廣泛應用于變電站、輸配電系統(tǒng)等場景。11017
JS-7 Surge Counter Product Description (English)
The JS-7 Surge Counter is a high-voltage electrical device designed to record the operating次數(shù) of surge arresters,串聯(lián) connected in the grounding circuit of arresters for 35kV and below voltage等級 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
功能特點補充說明（中英雙語）
- 抗干擾設計：采用高速數(shù)據(jù)處理單元與數(shù)字濾波技術(shù)，確保雷電沖擊電流（8/20μS波形）下計數(shù)準確性。
Anti-interference Design: High-speed processing unit and digital filtering guarantee reliable counting under lightning impulses (8/20μS waveform).
- 分相記錄：支持三相系統(tǒng)中各相間動作的獨立累計，幫助定位異常相位。
Phase-Segregated Recording: Independent cumulative counts per phase aid in fault phase identification.
- 簡易維護：觀察窗防塵設計，電池更換無需工具，簡化現(xiàn)場運維。
Low Maintenance: Dust-proof window and tool-free battery replacement streamline field service.139
