FUNCTIONAL MEASURING UNIT FOR MEDUIM-VOLTAGE DISTRIBUTION SUBSTATION

摘要

The design of a functional measuring group (40) for a medium-voltage substation has been optimized to make the product compact and robust in terms of internal arc, and also to favour complete accessibility to the measurement sensors. In particular, the voltage sensors (44) are located in a vertical plane directly accessible via the front panel of the group (40), and the current sensors (46) are located in the rear housing of the group (40), being directly accessible via the top of the group. In addition to being placed in an insulated compartment (40'), the voltage sensors (44) are insulated and shielded, and their connection terminals (48) are designed for connection by cable (300) with a flat interface.
