1. TP483000D Cabinet Configuration
AC cabinet: TPA38631B-N20C, TPA38401B-N20C1
Rectifier cabinet: TPR48202B-N20C5 , TPR48302B-N20C5
DC cabinet: TPD48202B-N20C1, TPD48302B-N20C1
Intelligent PDC: TPD48202B-N20C6
Lithium battery cabinet: TBC1000B-NDA1
Rectifier: R48100G1
2. Cabinet Layout Rules
The TP483000D consists of AC cabinets, Rectifier\ cabinets, and DC cabinets. The TP483000D can be configured with intelligent power distribution cabinets and lithium battery cabinets. The cabinet layout rules are as follows:
● Rectifier cabinets and DC cabinets must be placed alternately.
● If the intelligent PDC is configured, it is placed together with the DC cabinet.
● AC cabinets must be placed at the ends of the system.
NO TICE
● A maximum of eight cabinets can be connected in parallel. The following uses two cabinets as an example. If more than two cabinets are connected in parallel, contact Huawei technical support.
● The TP483000D supports a maximum of six battery cabinets. Battery cabinets are combined using copper bars. It is recommended that three battery cabinets be combined.
● You are advised to use cables to connect the battery cabinet and the DC cabinet.
● The intelligent PDC can connect to a DC cabinet through cables or connect to a DC cabinet (Rectifier cabinet) by using copper bars. When connecting to a DC cabinet (Rectifier cabinet) using copper bars, install an extension copper bar in the DC cabinet (Rectifier cabinet).
3. Multi-cabinet Management Rules
● If AC, combined or Rectifier and DC cabinets are connected together, the cabinets are cascaded using CAN communications cables and are centrally managed by the master monitoring unit of the combined or Rectifier cabinet.
● If there are multiple Rectifier cabinets, set the SMU02C in one Rectifier cabinet as the master and the SMU02Cs in other Rectifier cabinets as slaves. The SMU02C address of the slave server is automatically allocated and can be manually set.
● If there are multiple Rectifier cabinets, the information (system information) and alarms (system alarms) displayed on each MDU are the same.
● Dry contact inputs and outputs of a cabinet are connected to the master monitoring unit preferentially and then connected to the slave monitoring unit. Dry contact parameters are configured on the monitoring unit of the cabinet where the dry contact cables are located.
● Sensor cables of a cabinet are connected to the master monitoring unit preferentially. Sensor parameters are configured on the monitoring unit of the cabinet where the sensors are located.
● Northbound communications cables and southbound intelligent devices of a cabinet can only be connected to the master monitoring unit, and their parameters are configured on the master monitoring unit.
4. Removing Side Panels from Cabinets
Context
● If the battery cabinet and DC cabinet are combined using copper bars, remove the side doors of the DC cabinet and battery cabinet.
● If the battery cabinets are combined, remove the side doors of the battery cabinets.
● If multiple Rectifier cabinets, DC cabinets, and intelligent PDCs are combined, remove the upper side panels between the combined Rectifier cabinets, DC cabinets, and intelligent PDCs. NO TE
● Set the removed side panels and screws aside and install them onto cabinets that have no side panels at the two ends of the power system.
● This section describes how to remove side panels for reference only. The side panels to be removed are subject to the actual site configurations
5. Installing Connecting Copper Bars (Intelligent PDC, Rectifier Cabinet, DC Cabinet)
When the intelligent PDC and intelligent PDC, intelligent PDC and Rectifier cabinet, and intelligent PDC and DC cabinet are combined, connecting copper bars needs to be installed on the RTN+ busbar and –48 V busbar.
CAUTION
When you install connecting copper bars, place them on a support kit to prevent them from falling.
Procedure
Step 1 Remove the rodent-proof mesh and beams from the top of the cabinets.
Step 2 Unscrew and remove the rear door of the Rectifier cabinet.
Step 3 Install a connecting copper bar for the –48V busbars.
Step 4 Install a connecting copper bar for RTN+ busbars.
Step 5 Reinstall the rodent-proof mesh and beams on the top of the cabinets.
