Intelligent Motor Protection Relay Apply in Bangladesh Cement Factory

摘要：電動機設備是水泥企業中應用較廣泛的動力裝置，而水泥生產企業屬于能耗高、污染大又需要設備連續不間斷工作的行業，電動機作為水泥行業設備的動力來源，其安全、穩定可靠的運轉對水泥行業的平穩生產起著至關重要的作用。

Abstract: Motor equipment is widely used in cement enterprises in power plant, and cement production enterprise belong to high energy consumption, pollution, large and continuous uninterrupted work need equipment industry, the electric motor as the power source of the cement industry equipment, the safe, stable and reliable operation, steady production of cement industry plays a vital role.

1.項目概述 Project Description

 隨著現代化水泥工業生產規模增加，生產設備也越來越大型化，因此所需用的拖動電動機的功率也越來越大。水泥廠生產工藝流程較復雜，可以總結水泥生產過程為生料制備（一磨）、熟料煅燒（一燒）、水泥粉磨（二磨）。因此，低壓電動機作為水泥生產過程中較常用的機組，數量多、種類復雜，隨著科學技術的不斷進步和工藝控制過程的不斷完善，尤其是自動化生產要求，迫切需要開發和完善電動機的控制和保護設備，實現對整個自動化生產過程和大型機械的遙控、遙測、遙調、故障診斷以及集中控制等功能

孟加拉水泥廠客戶找到我們， 購買了ARD2F系列的 智能型電動機保護器。

With the increase of modern cement industry production scale, production equipment is also more and more large, so the power of the drag motor is also more and more large.The production process of cement plant is complicated. The cement production process can be summarized as raw material preparation (first grinding), clinker calcination (first burning) and cement grinding (second grinding).Therefore, the low-voltage motor, as the most commonly used unit in cement production process, has a large number and a complex type. With the continuous progress of science and technology and the continuous improvement of process control process, especially the requirements of automatic production, there is an urgent need to develop and improve the control and protection equipment of the motor.Realize the whole automatic production process and large machinery remote control, remote measurement, remote adjustment, fault diagnosis and centralized control and other functions

The customer of Bangladesh Cement factory came to us and bought the ARD2F series intelligent motor protector
