CM801 integral (integral) low voltage motor intelligent controller

CM801一体式(整体式)结构,主机模块显示模块和互感器模块为一个整体,可灵活装置在MNS、GCS、GCK、GGD等各种抽出式(含1/4抽屉)、固定式及混合式柜型。适用于电力、石油化工、金属冶炼、制造、轻工、煤炭等诸多行业。

功能特征:

1、监控器具有过载维护、欠载维护、断相及三相不平衡维护、堵转维护、接地维护、漏电维护、线路维护、欠压及过压维护。

2、具有起动延时功能,可避开起动大电流,它和过载举措时间离开。监控器内置电流互感器和零序电流互感器(可选),丈量精度高并且抗干扰能力强。

3、具有自动复位功能及起动方法功能(如:星三角起动、自耦变压器起动、频敏变阻器起动)等诸多功能。

4、具有接地漏电维护输出、报警及预警功能(实时监控、提前发出警示信号、正常状态 时自动解除预警信号和故障跳闸)。

5、具有故障记忆及电机运行时间积累记忆功能,可供用户查看故障状态及电机的运行积累时间。

6、基于微机和数字处理技术,丈量精度高、线性好、故障区分率准确,抗干扰能力强。

7、采用E2PROM存储记忆技术,实现参数设定断电后设定参数仍保管下来,无须再设定。

8、配有设置键、移位键、数据键、复位键可对各种参数进行设定及修改。

9、一机多用,可取代电压表、电流表、热继电器、电流互感器、时间继电器、漏电继电器、电流变送器等。

10、具有4~20mA模拟量输出接口及RS485远程通讯接口,便当和上位机组成网络监控系统。通过上位机对监控器的维护参数进行设定和修改、运行状态监控和起停操作、历史数据盘问等。

11、采用背插式结构,强弱电完全离开,可大大减少外部电磁干扰在弱电侧的耦合,增强装置的抗干扰能力,提高其可靠性和平安性。

CM801 integral (integral) structure, the host module display module and the transformer module as a whole, can be installed in the MNS, GCS, GCK, GGD and other drawing (including 1/4 drawer), fixed type and hybrid type cabinet. Applicable to electricity, petrochemical, metal smelting, manufacturing, light industry, coal and many other industries.

Functional characteristics:

1 、 monitor has overload protection, under load protection, phase failure and three-phase unbalanced protection, blocking protection, earth protection, leakage protection, line protection, undervoltage and over-voltage protection.

2 、 with starting delay function, can avoid starting high current, it is separated from overload action time. The monitor is equipped with current transformer and zero sequence current transformer (optional), with high measuring accuracy and strong anti-interference ability.

3 、 automatic reset function and start mode function (such as: star delta start, autotransformer start, frequency sensitive rheostat start) and many other functions.

4 、 with earth leakage protection, output, alarm and early warning function (real-time monitoring, warning signal ahead of time, the normal state automatically lift early warning signal and fault tripping).

5, with memory failure and motor operation time accumulation memory function, can be used for users to see the fault state and motor operation accumulation time.

6 、 based on microcomputer and digital processing technology, the measurement accuracy is high, the linearity is good, the fault resolution is accurate, and the anti-interference ability is strong.

7, E2PROM memory technology is adopted to realize the parameter setting. After the power cut, the setting parameters are still saved without setting up.

8, with settings keys, shift keys, data keys, reset button, you can set and modify various parameters.

9, one machine multi-purpose, can replace the voltmeter, ammeter, thermal relay, current transformer, time relay, leakage relay, current transmitter, etc..

10, with 4 ~ 20mA analog output interface and RS485 remote communication interface, convenient and host computer network monitoring system. The protection parameters of the monitor are set and modified by the host computer, the monitoring of the running status and the operation of stop and stop, and the inquiry of historical data, etc..

11, the use of back inserted structure, strong and weak electricity is completely separated, can greatly reduce the external electromagnetic interference in the weak side of the coupling, and enhance the anti-interference ability of the device, improve its reliability and security.
