 Application of Intelligent Motor Protector in Yemen Chemical Industry


1.背景信息Background

現代化工工業(yè)中,電動(dòng)機作為一種拖動(dòng)機械,成為所有動(dòng)力機械基礎,科學(xué)技術(shù)不斷進(jìn)步和工藝控制不斷完善,尤其是自動(dòng)化生產(chǎn)要求,迫切需要開(kāi)發(fā)和完善電動(dòng)機控制和保護設備,實(shí)現對生產(chǎn)過(guò)程和大型機械遙控、遙測、遙調、故障診斷以及集中控制等功能。

In modern chemical industry,  as a mechanical drag, electric motor become the foundation of all machinery. Improvement of science and technology progress and process control, especially the automation production requirements, make it urgent to develop and improve the motor control and protection equipment , so as to realize the function remote control, remote sensing, remote setting, fault diagnosis, and centralized control of of the production process and large machinery.

??同時(shí),化工行業(yè)具有大通量、滿(mǎn)負荷連續運轉特點(diǎn),對電機設備可靠性和穩定性要求較高,一旦發(fā)生事故,須馬上查找故障原因并及時(shí)除掉,以保證及時(shí)恢復生產(chǎn),對于過(guò)去一直采用熱繼電器作為電動(dòng)機過(guò)載保護和控制元件,受到元件質(zhì)量和工藝限制,已無(wú)法滿(mǎn)足日益發(fā)展化工工業(yè)自動(dòng)化要求,而新型的智能電動(dòng)機保護器,能夠滿(mǎn)足對電動(dòng)機的保護控制要求,作為電動(dòng)機保護元件,電動(dòng)機保護器合理保障了電機安全運行、取代了熱繼電器,利用通訊技術(shù),實(shí)現了電機控制自動(dòng)化,并取了顯著(zhù)經(jīng)濟效益.

At the same time, the chemical industry have the characteristics of large flux, full load continuous operation, has high requirements for electrical equipment reliability and stability.Once there is an accident, the cause of the problem must been quickly checked and problems must been promptly eliminate, in order to timely recover to produce.In the past ,thermal relay have been used for motor overload protection or use as control components, but limited by component quality and technology, have been unable to meet the development of chemical industrial automation requirements, and new type of intelligent motor protector, can meet the requirement of the protection of motor control. As a motor protection device, motor protector effectively guarantee the safe operation of the electric motor, replaced the thermal relay, By using advanced communication technology, has realized the motor control automation, and take the significant economic benefits.

4.ARD2F智能型電動(dòng)機保護器在化工行業(yè)的運行效果Performance of ARD2F intelligent motor protector in chemical industry

ARD2F智能型電動(dòng)機保護器運用到化工行業(yè)時(shí),給化工的自動(dòng)化生產(chǎn)過(guò)程帶來(lái)如下運行效果:

When ARD2F intelligent motor protector is applied to the chemical industry, it brings the following operation effects to the automatic production process of chemical industry:

(1)系統信息集中System information centralization

用戶(hù)可以通過(guò)抄表的方式采集各個(gè)裝置節點(diǎn)的參數,如:電動(dòng)機電流、電壓、電動(dòng)機運行情況、電能等,用戶(hù)根據這些信息實(shí)現了對現場(chǎng)設備的電動(dòng)機運行情況實(shí)時(shí)分析處理;

User can collect the parameters of each device node by means of meter reading, such as motor current, voltage, motor running status, electric energy, etc. According to these information, the user realizes real-time analysis and processing of the motor running status of field equipment.

(2)智能化控制保護Intelligent control protection

化工生產(chǎn)過(guò)程中使用ARD2F智能型電動(dòng)機保護器后,如果電動(dòng)機出現過(guò)載、缺相、超溫等現象時(shí),保護器將及時(shí)終止電動(dòng)機的運行,并對各種故障信息作出相應的指示,在電網(wǎng)故障造成電壓瞬間較大幅度的波動(dòng)或者短時(shí)斷電又恢復,帶抗晃電功能時(shí)可使電動(dòng)機保護器重新起動(dòng);

When ARD2F intelligent motor protectors are used in the Chemical production process , if motors have the phenomenon such phase loss, over temperature, protector will timely stop motor running, and makes the corresponding instructions for a variety of fault information。The motor protector with anti-electricity shaking function, can be restarted when the power grid fault causes instantaneous and large voltage fluctuation or the short-time power cut and restored.

(3)故障記錄便于現場(chǎng)問(wèn)題分析Fault recording facilitates field problem analysis

在化工行業(yè)中,電動(dòng)機發(fā)生故障后,應及時(shí)的把備用電動(dòng)機投上而不影響運行機制,對出現問(wèn)題的電動(dòng)機應及時(shí)處理以確保連續生產(chǎn),早期的處理方法需要花大量的人力物力還需要一定的時(shí)間才能分析出來(lái),不便于應用,而ARD2F智能型電動(dòng)機保護器強大的故障記錄功能為維護人員節省了大量的時(shí)間,提高了生產(chǎn)的效率及系統運行可靠性。

In the chemical industry, when electric motor falure occurs,  spare motor need to been timely replaced without affecting the operation mechanism.The motor pwith problem should be dealt with in time to ensure continuous production.The early treatment methods need a lot of manpower and material resources and need a certain amount of time to analyze, really not convenient.But ARD2F intelligent motor protector's powerful fault recording function saves maintenance personnel a lot of time, improves production efficiency and system operation reliability.
