1.背景信息Background

現代化工工業中，電動機作為一種拖動機械，成為所有動力機械基礎，科學技術不斷進步和工藝控制不斷完善，尤其是自動化生產要求，迫切需要開發和完善電動機控制和保護設備，實現對生產過程和大型機械遙控、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，化工行業具有大通量、滿負荷連續運轉特點，對電機設備可靠性和穩定性要求較高，一旦發生事故，須馬上查找故障原因并及時除掉，以保證及時恢復生產，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，受到元件質量和工藝限制，已無法滿足日益發展化工工業自動化要求，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，實現了電機控制自動化，并取了顯著經濟效益.

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， 2019年底，在網上尋找工廠能耗系統，并能接入SAP系統，聯系到了安科瑞。安科瑞是一家集研發、生產、銷售和服務于一體的高新技術企業，致力于為電力用戶端提供能效管理和用電安全的系統解決方案。安科瑞電氣具備從云平臺軟件到末端元器件的完整生產線。公司當時正有計劃開發工廠能耗。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，并有計劃的續訂其他產品。

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.
