【摘要】：母线舱是GIS(Gas Insulated Switchgear,气体绝缘密封式设备)组合电器的重要构成组件,安装在母线舱上,在安装的过程中,使用波纹补偿器来对设备生产和安装过程中造成的误差进行必要的补偿。波纹补偿器在环境温度出现剧烈的变化的情况下,如果波纹补偿器在频繁的拉伸与压缩等外力作用下进行变化,极易出现金属疲劳,从而不能对误差进行充分的补偿,在这种情况下,母线舱极易出现舱体焊缝开裂、气体泄漏等故障,影响电网运行安全。因此,为了保障变电站安全稳定运行,本文旨在构建一套对GIS母线舱形变位移监测并对超阈值的形变进行预警的在线实时监测系统,用于实时监测GIS母线舱伸缩节的位移形变等信息,分析其成因和危害,对超过设备允许的变形和应力做出预警,保证GIS组合电器母线舱安全稳定可靠运行。在母线舱位移形变监测系统开发和建设实施中,作者除了在系统建设的前期参与了系统架构的设计工作以外,对系统需求的了解、总结和系统原型界面设计等工作内容也进行了积极的参与;在系统的编码实现过程中,客户端设备管理模块、监控管理模块、客户端连接管理模块、位移数据接收和管理模块、报警模块和数据分析模块的编码实现也是有作者独立或者参与下完成的。参与对数据库的设计,参与了组合式位移信息采集传感器模块的设计与开发。在测试阶段,笔者参与完成了系统的功能测试和所有模块的单元测试。本文所设计的母线舱位移形变监测系统主要由组合式位移信息采集传感器模块、位移信息接收与发送模块和母线舱位移形变监测控制系统三个部分组成。组合式位移信息采集传感器模块通过传感器组,采集表征GIS组合电器母线舱运行状态的部分信息,并做初步处理,同时设计便于安装、调试和运维的夹持装置;位移信息接收与发送模块将Zigbee无线传感网络控制器技术应用在智能终端技术平台,实时归集各项监测数据,并通过无线网络传输技术,将归集后的信息发送到母线舱位移形变监测控制系统的数据处理单元;母线舱位移形变监测控制系统采用B/S模式构建,具有终端管理、实时数据监测、实时数据曲线显示、历史数据显示、数据分析及异常情况报警提醒等功能。目前,该系统处于试运行阶段,笔者所负责的模块功能稳定、运行正常,达到了预期目标。
[Abstract]:Busbar compartment is an important component of GIS(Gas Insulated switch gear. The corrugated compensator is used to compensate the errors caused during the production and installation of the equipment. The corrugated compensator changes dramatically in the ambient temperature. If the corrugated compensator changes under the action of external forces such as frequent tension and compression, it is easy to appear metal fatigue, so that the error can not be fully compensated. In this case, the busbar cabin is prone to crack in the hatch weld. Therefore, in order to ensure the safe and stable operation of substation, this paper aims to construct an on-line real-time monitoring system for monitoring deformation displacement of GIS busbar cabin and warning the deformation over threshold. It is used to monitor the displacement and deformation information of the GIS busbar cabin telescopic joint in real time, analyze its cause and harm, and make early warning of the deformation and stress that exceed the equipment allowable. In order to ensure the safe, stable and reliable operation of the GIS combined electrical busbar cabin, in the development and construction of the system, the author not only participated in the design of the system architecture in the early stage of the system construction, but also understood the requirements of the system. In the coding process of the system, the client equipment management module, the monitoring management module, the client connection management module, the displacement data receiving and managing module, the client connection management module, the displacement data receiving and managing module, etc. The coding implementation of alarm module and data analysis module is also completed by the author independently or with the participation of the author. It participates in the design of database and the design and development of the combined displacement information acquisition sensor module. The author participated in the function test of the system and the unit test of all modules. The displacement information receiving and transmitting module and the bus compartment displacement monitoring and controlling system are composed of three parts. The combined displacement information acquisition sensor module collects some information about the running state of the GIS composite electrical busbar cabin through the sensor group. At the same time, the clamping device is designed to be convenient for installation, debugging and operation. The displacement information receiving and transmitting module applies the Zigbee wireless sensor network controller technology to the intelligent terminal technology platform, and gathers the monitoring data in real time. Through the wireless network transmission technology, the collected information is sent to the data processing unit of the monitor and control system of the bus slot displacement and deformation, the system is constructed by B / S mode and has terminal management. The functions of real-time data monitoring, real-time data curve display, historical data display, data analysis, and alarm and warning of abnormal situation are all functions. At present, the system is in the stage of trial operation, and the function of the module the author is responsible for is stable and running normally. The target was achieved.
