Application of Intelligent Motor Protector in Yemen Chemical Industry

1.背景信息Background

現(xiàn)代化工工業(yè)中,電動機作為一種拖動機械,成為所有動力機械基礎(chǔ),科學(xué)技術(shù)不斷進步和工藝控制不斷完善,尤其是自動化生產(chǎn)要求,迫切需要開發(fā)和完善電動機控制和保護設(shè)備,實現(xiàn)對生產(chǎn)過程和大型機械遙控、遙測、遙調(diào)、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,化工行業(yè)具有大通量、滿負(fù)荷連續(xù)運轉(zhuǎn)特點,對電機設(shè)備可靠性和穩(wěn)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除掉,以保證及時恢復(fù)生產(chǎn),對于過去一直采用熱繼電器作為電動機過載保護和控制元件,受到元件質(zhì)量和工藝限制,已無法滿足日益發(fā)展化工工業(yè)自動化要求,而新型的智能電動機保護器,能夠滿足對電動機的保護控制要求,作為電動機保護元件,電動機保護器合理保障了電機安全運行、取代了熱繼電器,利用先進通訊技術(shù),實現(xiàn)了電機控制自動化,并取了顯著經(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.

2.項目背景Project Ground

也門客戶YCGSI是一家化工型企業(yè), 2019年底,在網(wǎng)上尋找工廠能耗系統(tǒng),并能接入SAP系統(tǒng),聯(lián)系到了安科瑞。安科瑞是一家集研發(fā)、生產(chǎn)、銷售和服務(wù)于一體的高新技術(shù)企業(yè),致力于為電力用戶端提供能效管理和用電安全的系統(tǒng)解決方案。安科瑞電氣具備從云平臺軟件到末端元器件的完整生產(chǎn)線。公司當(dāng)時正有計劃開發(fā)工廠能耗。客戶12月底參觀完上海總部,深入交流后,決定從元器件電動機保護器先開始采購試用,到目前為止,客戶反饋比較滿意,并有計劃的續(xù)訂其他產(chǎn)品。

YCGSI, a chemical company based in Yemen, contacted Acrel in late 2019 after its engineer searched online for the factory energy management system which can connected to SAP. Acrel is a high-tech enterprise integrating research and development, production, sales and service. It is committed to providing energy efficiency management and power safety system solutions for power users. Acrel Electric has a complete production line from cloud platform software to components.The company was planning to develop factory energy management system.The customer visited the headquarters in shanghai at the end of December, and after in-depth communication, they decided to start the purchase trial from the motor protector. So far, the customer has given satisfactory feedback, and has planned to renew other products.

3.化工行業(yè)對保護器功能要求Function requirement of protector in chemical industry

安科瑞ARD2F電動機保護器能對電動機運行過程中出現(xiàn)的起動超時、過載、堵轉(zhuǎn)、斷相、不平衡、欠載、接地/漏電、阻塞、過壓、欠壓、繞組超溫等多種情況進行保護,能夠?qū)崿F(xiàn)運行時間、次數(shù)統(tǒng)計等功能,對電機的運行電流、電壓、運行時間、起動次數(shù)、報警和故障信息等進行監(jiān)視,設(shè)有SOE故障事件記錄功能,方便現(xiàn)場維護人員查找故障原因,并通過LCD液晶顯示屏、狀態(tài)指示燈等各種方式,將電機的運行狀態(tài)清晰、直觀地顯示出來,該保護器具有RS485遠程通訊接口,DC4~20mA模擬量輸出,方便與PLC、PC等控制機組成網(wǎng)絡(luò)系統(tǒng),實現(xiàn)實現(xiàn)在人機界面對電動機監(jiān)視,滿足化工行業(yè)對電動機保護器的需求。

Acrel ARD2F motor protector can protect motor in the process of starting timeout, overload, locked-rotor, imbalance, phase loss, underload, grounding/leakage, block, overvoltage, undervoltage, winding over temperature and other condition. It realize the function of counting running time, frequency, monitor motor operating current, voltage, running time, starting time, alarm and fault information. It also have the function of SOE failure event record, convenient for maintenance staff to find the causes.Through LCD liquid crystal display and status indicators and so on, running state of the motor is displayed clearly and intuitively. The protector has RS485 remote communication port and DC4-20mA analog output, which is convenient to form a network system with PLC, PC and other control units, realize the monitoring of the motor in the human-machine interface, and meet the needs of the chemical industry for the motor protector.

4.ARD2F智能型電動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智能型電動機保護器運用到化工行業(yè)時,給化工的自動化生產(chǎn)過程帶來如下運行效果:

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(tǒng)信息集中System information centralization

用戶可以通過抄表的方式采集各個裝置節(jié)點的參數(shù),如:電動機電流、電壓、電動機運行情況、電能等,用戶根據(jù)這些信息實現(xiàn)了對現(xiàn)場設(shè)備的電動機運行情況實時分析處理;

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)過程中使用ARD2F智能型電動機保護器后,如果電動機出現(xiàn)過載、缺相、超溫等現(xiàn)象時,保護器將及時終止電動機的運行,并對各種故障信息作出相應(yīng)的指示,在電網(wǎng)故障造成電壓瞬間較大幅度的波動或者短時斷電又恢復(fù),帶抗晃電功能時可使電動機保護器重新起動;

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(xiàn)場問題分析Fault recording facilitates field problem analysis

在化工行業(yè)中,電動機發(fā)生故障后,應(yīng)及時的把備用電動機投上而不影響運行機制,對出現(xiàn)問題的電動機應(yīng)及時處理以確保連續(xù)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間才能分析出來,不便于應(yīng)用,而ARD2F智能型電動機保護器強大的故障記錄功能為維護人員節(jié)省了大量的時間,提高了生產(chǎn)的效率及系統(tǒng)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.

6.結(jié)束語Ending

隨著當(dāng)代控制技術(shù)的不斷發(fā)展,電動機已經(jīng)成為控制系統(tǒng)中重要的一部分,電動機保護器也朝著多元化方向發(fā)展,因此我們工作人員需要充分考慮電動機保護實際需求,超前、準(zhǔn)確、及時地判斷電動機的故障,合理選擇保護功能和保護方式,實現(xiàn)對電動機的良好保護,達到提高設(shè)備運行可靠性,減少非計劃停車,減少事故損失的目的,電動機保護器是發(fā)電、供電、用電系統(tǒng)的重要器件,廣泛的采用電動機保護器,不但可以提高工藝控制準(zhǔn)確性、科學(xué)性,降低故障率,而且對于提高電氣控制系統(tǒng)的自動化水平和發(fā)展國民經(jīng)濟,起著積極的推動作用。

With the continuous development of modern control technology, the motor has become an important part of the control system, and the motor protector is also developing in a diversified direction.Therefore, we should give full consideration to the actual needs of motor protection, judge motor faults in advance, accurately and timely, rationally select protection functions and protection modes, so as to realize good protection of the motor, improve the reliability of equipment operation, reduce unplanned shutdown and reduce accident losses.Motor protector is an important component of power generation, power supply and electricity consuption system. The widespread use of motor protector can not only improve the accuracy and scientificity of process control, reduce the failure rate, but also play a positive role in promoting the automation level of electrical control system and the development of national economy.
