Product installation instruction
Terminal definition and arrangement diagram
Power line connection
1. The power line selects multi-core copper conductors with appropriate cross-sectional area according to the total capacity of the product. Capacitors with a total capacity of 40kvar or more should adopt multi-core copper conductors with a cross-section of 16mm², and otherspecifications can use multi-core copper conductors of 10mm²;
2. Attention: When connecting the power line, you must select the copper wire of the corresponding specification, tighten the screw, and pull the power cord firmly to ensure that the connection is very firm before use, otherwise the terminal will be excessively heated, which will eventually lead to product damage. The sub-compensated smart capacitor must be connected to the neutral line, and the wire diameter specification is the same as the three-phase power supply.
Signal line connection
1. The secondary current signal line is connected by a network cable;
2. The RS485 communication line adopts the plug-in connection of the network cable, and the two smart capacitors can be directly connected by the communication line accessories
Indicator terminal wiring
If the user has the requirements for the output capacitor status indicator, the external indicator can be as follows:
1. Common compensation: C1 (terminal) and C2 (terminal) are the active signal output terminals of the two sets of capacitor switching status indicators. The C1 and C2 outputs are connected to one end of two AC 380V indicators, and the other end of the indicator light. Connect to phase B (or phase C).
2. Split-compensation : Ca (terminal), Cb (terminal), Cc (terminal) are the active signal output terminals of the threephase capacitor switching status indicator of the supplementary A, B and C. Ca, Cb, and Cc are connected to one end of three AC 220V indicators, and the other end of the indicator is connected to the common terminal (N).
Current transformer wiring Primary CT installation position
Secondary CT installation
1) Common compensation Pass the B-phase primary CT output line through the single-hole secondary CT configured by the company, and the secondary CT outputs a terminal cable port. When multiple networked networks are running, only the secondary CT needs to be connected to the host, and the slave only needs to be connected to the host through the network cable;
2) Split-compensation The A-phase, B-phase, and C-phase primary CT output lines are respectively passed through the three-hole secondary CT configured by the company, and the secondary CT output end is connected to the network cable port. When multiple networked networks are running, only the secondary CT needs to be connected to the host, and the slave only needs to be connected to the host through the network cable.
WARNING: Primary CT sampling (7A1A, TA1B, TA1C) should be installed in front of the capacitor and load in front of the contact (at the bus), and pay attention to the phase sequence.
Ground wire connection There is a grounding mark at the grounding wire. The grounding wire is a copper wire with a cross-sectional area of not less than 2.5 mm². The grounding must be reliable and connected to the external grounding terminal.
