Main product model specifications
When selecting the type, the special specification capacity can be negotiated.
Common compensation products, 5-40kvar other capacity can be customized.
Split compensation products, other capacity within 5-30kvar can be customized.
Communication line ordering coding rule
The communication line is used for communication between two adjacent smart capacitors in the same network (cabinet). The communication line is an 8-core conventional network cable. The product body comes with a 20cm network cable. Customers can customize it if they need other sizes.
Secondary transformer order coding rules
When the product is used as active control for reactive power com pensation, the secondary curren t transformer for sampling must be configured. (≤ 20 units)
The secondary current transformer is used for current sampling , and the secondary current (0-5A) of the primary current transformer of the incoming line cabinet is again converted. It is a (0~5mA) current signal.
A system of secondary transformers with one:
Only a total complemented network system is equipped with a single-hole secondary current transformer;
The networking system with sub-compensation is equipped with a three-hole secondary current transformer.
This accessory is not required when networked with an external controller(JKGPJ).

1. The temperature means that when the internal temperature of the product exceeds the set value during the use, the product will automatically exit the operation, which can effectively protect the product, and the customer can adjust according to their actual use requirements.(40°C ~80°C )
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.
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
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).
Primary CT installation position
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;
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.
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.
