 Intelligent Motor Protection Relay Apply in Bangladesh Cement Factory

摘要：电动机设备是水泥企业中应用较广泛的动力装置，而水泥生产企业属于能耗高、污染大又需要设备连续不间断工作的行业，电动机作为水泥行业设备的动力来源，其安全、稳定可靠的运转对水泥行业的平稳生产起着至关重要的作用。

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.项目概述 Project Description

   随着现代化水泥工业生产规模增加，生产设备也越来越大型化，因此所需用的拖动电动机的功率也越来越大。水泥厂生产工艺流程较复杂，可以总结水泥生产过程为生料制备（一磨）、熟料煅烧（一烧）、水泥粉磨（二磨）。因此，低压电动机作为水泥生产过程中较常用的机组，数量多、种类复杂，随着科学技术的不断进步和工艺控制过程的不断完善，尤其是自动化生产要求，迫切需要开发和完善电动机的控制和保护设备，实现对整个自动化生产过程和大型机械的遥控、遥测、遥调、故障诊断以及集中控制等功能

孟加拉水泥厂客户找到我们， 购买了ARD2F系列的 智能型电动机保护器。

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
