Schematic Diagram of Product Wiring

Product wiring requirements ：Specification of the connecting wire between the product and the power supply end: Generally, for a singleco compensating capacitor with a total capacity of over 30kvar and a sub compensating capacitor with atotal capacity of 20kvar, a standard 16m㎡cross-sectional area of multi-core copper wire should be used.while for other specifications, a standard 10m㎡ cross-sectional area of multi-core copper wire shouldbe used.

Specification of signal wire connection between products: The signal wire includes current sampling wireRS-485 communication wire, indicator light wire, external control signal input wire, etc. The current carriedon the signal line is very small, so a copper wire with appropriate strength can be selected. Generally, amulti-core copper wire with a cross-sectional area of about 0.75m㎡ is used.The RS-485 communication lines between each station are connected in parallel. Connect the currentsignal wire in parallel to the output terminal of the secondary current transformer.

Terminal arrangement and definition:The wiring terminals of the product are divided into power supply terminals and measurement and controlonline terminals, both located at the rear of the product. The three-phase compensation power supplyterminals have "UA, UB, UC", and the split phase compensation power supply terminals have "UA, UB,UC, UN" measurement and control online terminals that use plug-in components for on-site debuggingand replacement.
