预制舱式变电站舱体内、外运维通道设置方案研究

Research on the setting scheme of operation and maintenance channels inside and outside the cabin of prefabricated cabin substation

电气设备的安全性与可靠性的保障是非常重要的,由于预制舱式电气设备大部分运行于相对密封的室内环境,不直接遭受外界自然环境的影响,但预制舱只能提供相对良好的室内环境,无法完全隔绝外部环境,不同地区的气候环境对于电气设备仍存在一定的影响。另外,电气设备在运行过程中本身就存在一定程度的元件磨损,这对于电气设备的使用也会造成一定的影响。因此,对电气设备进行有效的运行管理及安全维护是非常重要的,这样才能够有效降低电气设备发生故障的概率,同时保证在电气设备发生故障时能够及时发现。预制舱和箱变项目在实际工程中已经得到了广泛应用,有一个典型的案例,展示了项目中实施的情况。该项目位于中国西藏那曲色尼区桑丹,项目规模为120MW,取到了良好的实施效果。

The guarantee of safety and reliability of electrical equipment is very important,because most of the prefabricated cabin electrical equipment operates in a relatively sealed indoor environment,not directly aff ected by the external natural environment,but the prefabricated cabin can only provide a relatively good indoor environment,can not completely isolate the external environment,the climatic environment in diff erent regions still has a certain impact on electrical equipment;in addition,electrical equipment itself has a certain degree of component wear during operation,which will also have a certain impact on the use of electrical equipment.Therefore,it is very important to carry out eff ective operation management and safety maintenance of electrical equipment,so as to eff ectively reduce the probability of electrical equipment failure,and ensure that electrical equipment can be found in time when it fails.Prefabricated cabin and box transformer projects have been widely used in actual engineering,and there is a typical case that shows the implementation of the project.The project is located in Sandan,Naqusenid District,Tibet,China,with a project scale of 120MW and has been well implemented.
