CM801 integral (integral) low voltage motor intelligent controller

CM801一體式(整體式)結構,主機模塊顯示模塊和互感器模塊為一個整體,可靈活安裝在MNS、GCS、GCK、GGD等各種抽出式(含1/4抽屜)、固定式及混合式柜型。適用于電力、石油化工、金屬冶煉、制造、輕工、煤炭等諸多行業(yè)。

功能特征:

1、監(jiān)控器具有過載保護、欠載保護、斷相及三相不平衡保護、堵轉保護、接地保護、漏電保護、線路保護、欠壓及過壓保護。

2、具有起動延時功能,可避開起動大電流,它和過載動作時間分開。監(jiān)控器內置電流互感器和零序電流互感器(可選),測量精度高而且抗干擾能力強。

3、具有自動復位功能及起動方式功能(如:星三角起動、自耦變壓器起動、頻敏變阻器起動)等諸多功能。

4、具有接地漏電保護輸出、報警及預警功能(實時監(jiān)控、提前發(fā)出警示信號、正常狀態(tài) 時自動解除預警信號和故障跳閘)。

5、具有故障記憶及電機運行時間積累記憶功能,可供用戶查看故障狀態(tài)及電機的運行積累時間。

6、基于微機和數(shù)字處理技術,測量精度高、線性好、故障分辨率準確,抗干擾能力強。

7、采用E2PROM存儲記憶技術,實現(xiàn)參數(shù)設定斷電后設定參數(shù)仍保存下來,無須再設定。

8、配有設置鍵、移位鍵、數(shù)據(jù)鍵、復位鍵可對各種參數(shù)進行設定及修改。

9、一機多用,可取代電壓表、電流表、熱繼電器、電流互感器、時間繼電器、漏電繼電器、電流變送器等。

10、具有4~20mA模擬量輸出接口及RS485遠程通訊接口,方便和上位機組成網(wǎng)絡監(jiān)控系統(tǒng)。通過上位機對監(jiān)控器的保護參數(shù)進行設定和修改、運行狀態(tài)監(jiān)控和起停操作、歷史數(shù)據(jù)查詢等。

11、采用背插式結構,強弱電完全分開,可大大減少外部電磁干擾在弱電側的耦合,增強裝置的抗干擾能力,提高其可靠性和安全性。

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.
