课程概述： 欢迎参加“掌握中压电路图”课程。本培训从基本概念开始，逐步深入到高级水平，注重实际操作和实践经验的传授。 导师介绍： 我们的讲师拥有超过21年的操作和维护、安装、测试、项目管理、咨询、监督以及变电站自动化和SCADA的经验。他曾在西门子沙特阿拉伯等知名企业工作，参与过巴基斯坦和沙特阿拉伯的20多个高压变电站项目。他的专业领域涵盖保护系统、变电站自动化系统、发电系统的设计、测试及调试、高压开关设备、保护继电器和控制方案等。他在为工业客户实施电气基础设施项目方面有着丰富的经验，包括钢铁和石化行业。 课程内容： 本课程为“掌握中压开关设备图纸”系列的第三部分，涵盖以下主题： - 触发命令和逻辑表 - 触发线圈保护方案 - 防撞击方案 - 免触发方案 - 断路器触发控制本地/远程/紧急/关闭 - 本地/远程的触发 - 紧急情况的触发 - 触发线圈1和2电路 - 从过流继电器触发 - 从电池备份继电器触发 - 从欠压/过压继电器触发 - 触发电路监控继电器 - 固态直流电、虚假直流电、返回直流电 - 测试灯 - ABB TCS 继电器 - MVAX 11、12、13 TCS 继电器 - 指示电路 - 二进制输入电路 - 回路监控 - 直流电源监控 - OG供电与接地开关的联锁 - 触发电路监控报警和关闭块逻辑 - 每个TCS产生报警 - 两个TCS故障意味着断路器无法打开（如果关闭，会很危险） - 如果两个TCS故障，断路器关闭块的概念 - 何时监测TC的健康状态，闭合或开启断路器 - 固态直流电、返回负电和正电的概念 - 什么是固态直流电 - 什么是返回负（正）电 - 虚假/假直流电 - 测试灯的使用 - 测试灯在故障排除中优于任何高科技工具 - TCS监控继电器SPER 1C1持续监控断路器触发电路和其他重要控制电路，预设操作时间以防止在断路器操作时发出不必要的报警信号，前面板的LED指示器和输出继电器指示继电器操作，能够检测到坏接点、接点焊接和监控电路中的辅助电压故障。 - TCS监控继电器MVAX12的功能。 本课程旨在为学员提供全面而实用的中压电路图知识。
Dear All,Welcome to the course "Mastering Medium Voltage Schematics". This training starts from a very basic level to an advanced level. Focus has been given to delivering practical and hands-on knowledge.Trainer Introduction:Your trainer brings over 21 years of experience in operation & maintenance, erection, testing, project management, consultancy, supervision, substation automation, SCADA, and commissioning. With a background spanning power plants, high voltage substations, and HVDC installations, he has worked with renowned organizations such as Siemens Saudi Arabia. He has been involved in over 20 high-voltage substation projects across Pakistan and Saudi Arabia.His expertise encompasses a wide range of areas including protection systems, substation automation systems, design, testing, and commissioning of power generation systems, high voltage switchgear, protection relays, and control schemes. He has a proven track record of leading testing and commissioning teams for implementing electrical infrastructure projects for industrial clients, including steel and petrochemical industries.This online course is part 03 of the Mastering Medium Voltage Switchgear drawings.
