One,Product Introduction

JGFH系列是一款新型的Current-Limiting Fire Alarm Protector(Current-Limiting Type电气防火保护器),具有过电压 、Undervoltage、Overcurrent、漏电、Temperature、烟雾、可燃气体检测的多种保护功能的综合型保护器,产品模块化、智能化、可视化等优点,同时支持标准Modbus485通讯协议,Overvoltage,Undervoltage、Overcurrent、漏电流、超温保护等所有参数可根据用电需求设定,确保线路中发生过电压、Undervoltage、Overcurrent等故障时保护器能瞬间切断电源 ,保护用电设备完好不损坏。

本系列产品结构紧凑、外观美观,Standard Rail Installation 。

二、Product Features

■Smoke And Flammable Gas Protection Function: For Electric Fields 烟雾、液化石油气、天然气、丙烷、丁烷等可燃气体超量时,保护器发出保护器发出声光报警信号,并自动切断电源,显示实时故障记录。

■短路保护功能:保护器实时监测用电线路电流,当线路发生短路故障时,能在0.1秒内实现快速限流保护,并显示实时故障记录。

■过载保护功能:当被保护线路的电流过载且过载持续时间超过动作时间(3~60秒可设)时,保护器启动限流保护,并显示实时故障记录。

■过欠压保护功能:当保护器检测到线路电压欠压或过压时,保护器自动切断电源,并显示实时故障记录。

■配电线缆Temperature监测功能:当被监测线缆Temperature超过报警设定值时,保护器自动保护切断电源,并显示实时故障记录。

■漏电流监测功能:当被监测的线路漏电超过报警设定值时,保护器自动保护切断电源,并实时显示故障记录。

■ 通讯组网功能:保护器具有1路RS485接口,可以将数据发送到后台监控系统,实现远程遥测、遥信、遥控、遥调、Five Remote Functions Of Remote Viewing.

■Neutral Wire And Live Wire Are Cut Off At The Same Time: When A Line Failure Occurs, The Product Cuts Off Both The Neutral And Live Wires At The Same Time. There Is No Danger Of Electrification On The Line Because The Neutral Line Is Not Cut Off.

■No Damage Due To Overvoltage: When The Line Is Wrongly Connected To The Three-Phase Power Supply, The Maximum Power Supply Voltage Is AC450V, And The Product Will Be Disconnected Within The Set Time. At The Same Time, The Product Itself Will Not Be Damaged By The High Voltage.

■Anti-Harmonic: At Present, The Power Consumption In The Power Grid Is Relatively Complex. There Are A Large Number Of Harmonics In The Power Grid. The Harm Of Harmonics Will Shorten The Life Of Other Electrical Equipment. This Product Will Not Be Affected In The Harmonic Power Grid.

■One-Click Recovery Function: When The User Is Not Proficient In Product Operation And The Set Parameters Do Not Meet The On-Site Protection Requirements, He Can Restore The Factory Settings With One Click To Avoid Incorrect Protection Problems Caused By Improper Operation.
