The battery charger provides voltage and power for the different cards. Generates alarm in the Relay when there is no AC voltage.
FUSE CARD AC
The AC fuse card generates overcurrent protection of the different AC voltage levels inside the cabinet. It also protects against over-voltage in the cabinet power supply.
The HS5 card is responsable for charging the capacitors that release the energy necessary for the GVR operation.
The HS9 card turn the AC voltage into DC to power the internal cards of the control cabinet. Generates overcurrent and over voltage protection.
The SF6 card detects if there is low SF6 gas pressure in the GVR, and is responsable for generating the alarm that is sent to the relay.
DC FUSE BOARD
The DC fuse card generates overcurrent protection in the different DC voltage levels inside the cabinet.
