AbolishedSeries of basic dimensions of subracks and associated panels of plug-in for control and protection equipment of secondary circuit of power system
电力系统二次回路控制、保护装置用插箱及插件面板基本尺寸系列
Application Summary AI generated
This standard specifies the basic dimensional series for subracks and associated plug-in panels used in the secondary circuits of power systems. It is applied in the design and manufacturing of control and protection equipment, such as relay protection devices and automation systems, ensuring mechanical interchangeability and compatibility between different manufacturers' components. The standard is critical for substations and power plants where standardized rack-mounted electronic modules must fit reliably into enclosures.
