1.背景信息Background

现代化工工业中，电动机作为一种拖动机械，成为所有动力机械基础，科学技术不断进步和工艺控制不断完善，尤其是自动化生产要求，迫切需要开发和完善电动机控制和保护设备，实现对生产过程和大型机械遥控、遥测、遥调、故障诊断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.

  同时，化工行业具有大通量、满负荷连续运转特点，对电机设备可靠性和稳定性要求较高，一旦发生事故，须马上查找故障原因并及时除掉，以保证及时恢复生产，对于过去一直采用热继电器作为电动机过载保护和控制元件，受到元件质量和工艺限制，已无法满足日益发展化工工业自动化要求，而新型的智能电动机保护器，能够满足对电动机的保护控制要求，作为电动机保护元件，电动机保护器合理保障了电机安全运行、取代了热继电器，利用先进通讯技术，实现了电机控制自动化，并取了显著经济效益.

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.项目背景Project Ground

也门客户YCGSI是一家化工型企业， 2019年底，在网上寻找工厂能耗系统，并能接入SAP系统，联系到了安科瑞。安科瑞是一家集研发、生产、销售和服务于一体的高新技术企业，致力于为电力用户端提供能效管理和用电安全的系统解决方案。安科瑞电气具备从云平台软件到末端元器件的完整生产线。公司当时正有计划开发工厂能耗。客户12月底参观完上海总部，深入交流后，决定从元器件电动机保护器先开始采购试用，到目前为止，客户反馈比较满意，并有计划的续订其他产品。

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.
