Planning and installation of the low voltage switchgear - The

InstallationImportant Planing ConsiderationsTransportation Switchgear UnitsDouble-Front InstallationsEnvironmental Conditions For SwitchgearSafety Against Arcing FaultsThe minimum clearances between switchgear and obstacles specified by the manufacturer must be taken into account when installing low-voltage switchgear (Figure 1). The minimum dimensions for operating and servicing corridors in accordance with IEC 60364-7-729must be taken into account when planning the space requirements (Figure 1, Figure 3). Where: 1. Minimum height of passage under covers or enclosures. 2. Attention:Above the panels, some space specified by the manufacturer MUST be free from obstacles to allow the pressure relief vents to open in the event of an arcing fault. Where: 1. With switchgear fronts facing each other, the space requirements only account for obstruction by open doors from one side (i.e. doors that don’t close in escape direction). 2. Take door widths into account, i.e. door can be opened at 90° minimum. Go back to Contents Table ↑Get price

Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price
