QJZ1-1200/1140(660)-4
矿用隔爆兼本质安全型组合式真空电磁起动器
Mine Explosion-proof and Intrinsically Safe Compound Vacuum Electromagnetic Actuator

适用范围及用途
起动器主要用于交流频率50Hz、额定电压1140V或660V供电线路中,对4台矿用隔爆型三相交流感应电动机或两台矿用隔爆型三相交流双
绕组双速电动机的起动、停止、反转及双速切换进行控制;同时对电动机及其有关线路进行保护;并可在停止时进行换向。

Applications
The actuator is mainly used for control of starting, stopping, reversion and double-speed switch of 4 mine explosion-proof three-phase AC induction motors or two
mine explosion-proof three-phase AC double-winding double-speed motors in the power supply circuit, with the AC frequency of 50Hz, rated voltage of 1140V or 660V. Besides, it’s suitable
for protection of the electromotor and relevant circuit and reversion when it stops working.

主要特征
1、全中文15×8汉字点阵液晶显示。
2、本质安全先导回路操作控制,远距离控制和本机控制选择。
3、具有过流、短路、欠压、断相、漏电闭锁、操作过电压等保护。
4、具备试验功能、显示功能、通讯功能、故障查询、故障记忆功能。
5、各保护功能参数可以通过菜单进行选择、调整、打开或者关闭。
6、保护器拥有先进的RS485或CAN接口通讯联网功能,通过连接器可接入局域网或因特网,给远程监控提供便利。具备遥控、遥调、遥测、
遥信四遥功能。

Features
1. Chinese liquid crystal display with15 × 8 Chinese character lattice.
2. The intrinsically safe operation control through the leading circuit, remote control, and self-control of the machine are all available.
3. It can provide protection from over current, short circuit, undervoltage, phase failure, leakage lockout, and operation overvoltage.
4. It has the function testing, display, communication, fault inspection, and fault memory.
5. The parameter of those protection functions is capable of selection, adjustment, and opening or closing in the menu.
6. It has advanced RS485 or CAN interface communications networking function. It can be connected to the LAN or the Internet, to facilitate remote monitoring and control. Besides, it has the
functions of remote control, remote adjustment, remote detection and remote communication.
