Product introduction
As an important component of substations,CKFG Series low-voltage shunt reactors can compensate for capacitive charging power, absorb reactive power, reduce line losses, and improve power factor. They can weaken the capacitance effect (Ferranti effect) of long lines under no-load or light-load conditions, stabilize the operating voltage of the power grid, and improve power supply quality. They can also reduce residual supply current, accelerate the extinction of residual supply arcs, help eliminate generator self-excitation, and reduce users' electricity expenses and production costs. Therefore, they have become an indispensable part of reactive power compensation in substations. Meanwhile, with the improvement of substation intelligence levels, low-voltage shunt reactors can be equipped with additional online monitoring functions to achieve condition-based maintenance, thereby saving investment in the full-life-cycle cost of equipment.
The CKFG-0.3/0.25-6% Reactor features a distinct structural design
This reactor is available in two types:
- three-phase and single-phase, both utilizing a dry-type iron core.
- The iron core consists of high-quality, low-loss, imported cold-rolled oriented silicon steel sheets. It is divided into uniform small sections by multiple air gaps, which are separated by epoxy-laminated glass cloth plates. These plates are bonded with a specialized adhesive to maintain the consistency of the reactance air gap throughout operation.
- The coil is constructed from H-grade or C-grade enameled flat copper wire, arranged in a tight and uniform manner.
- After the coil and iron core are assembled into a single unit, processes such as pre-drying, vacuum impregnation, and heat curing are conducted. H-grade impregnation paint is applied to securely bond the coil to the iron core.
- Non-magnetic materials are used for the clamps and fasteners of the reactor, ensuring a high quality factor and effective filtering performance.
- Additionally, all exposed components undergo anti-corrosion treatment, and the outgoing terminal switch is fitted with tinned copper tube terminals.
The Functions of Series Reactors
Voltage Adjustment
A series reactor provides voltage control in a circuit through its impedance characteristics. In situations where it is necessary to reduce voltage or provide additional voltage compensation, a series reactor may be used to do so. The impedance value of the series reactor has an effect on the voltage distribution in the circuit, thereby dictating the parallel voltage drop with respect to the power supply and load.
Current Limiting
The series reactor has the other function of limiting current in the circuit. By means of its impedance characteristics, the series reactor can limit the current magnitude so that excessive current does not damage the circuit components or the equipment. The series reactor would be adjusted in terms of its impedance according to the current requirements for a definite circuit design.
Resonant Circuit
Series reactors are considered significant in resonant circuits. Resonance refers to the resonance phenomenon generated by the inductance and capacitance in a circuit. By valuing the impedance of the series reactor adequately, one can alter and control the resonant frequency and frequency response. In resonant circuits, the series reactor is engaged in impedance matching and frequency selection, thus confining the circuit working to a definite frequency range.
Filter
Series reactors may also be utilized as filters. Filters are designed to select the series reactor's impedance value depending on circuit requirements in order to have filtering effects on specific frequency signals. By virtue of their impedance characteristics, series reactors will either eliminate signal components from a certain frequency range or attenuate them, thereby permitting the adjustment and filtering of the entire signal spectrum.
In summary, series reactors play various roles in circuit design, such as adjusting voltage, limiting current, being applied in resonant circuits and filters. By reasonably selecting the impedance value and quantity of series reactors, the performance and functions of the circuit can be controlled. The principle of series reactors is based on their impedance characteristics and circuit connection methods. The series-connected reactors successively affect the circuit signals or current to achieve the desired circuit effects.
Reactor Wiring Method
There are six terminals, ABC and XYZ. You can use ABC as the input terminals of the reactor and XYZ as the output terminals of the reactor; alternatively, you can use XYZ as the input terminals of the reactor and ABC as the output terminals of the reactor. There is no specific requirement for the order of input and output. It can be connected in any way without affecting the frequency converter. Just note one thing: when wiring, the two sets of terminals, ABC and XYZ, should not be cross-connected.

Details determine quality
The low-voltage series reactor uses high-quality accessories to ensure its excellent performance and reliability. It uses high-temperature resistant H-class polyester enameled wire, which has the characteristics of low line loss and high performance, and can effectively reduce energy loss while extending the service life of the equipment. By selecting high-quality materials, the reactor can maintain stable operation in various working environments and meet the needs of high efficiency and long life.
Galvanized copper tube terminals are made of high-quality galvanized materials with good ductility and conductivity, ensuring the stability and reliability of electrical connections. At the same time, the galvanizing treatment enhances the corrosion resistance of the terminals, enabling them to maintain excellent performance under various environmental conditions and extend their service life. This design not only improves the overall efficiency of electrical equipment, but also effectively reduces maintenance costs.
The wiring position of the normally closed contact of the thermostat is used to connect to the control circuit. Its working principle is: when the temperature exceeds the set value, the thermostat will automatically disconnect the circuit, thereby cutting off the power supply of the device. This function can effectively protect the device, ensure that it operates within a safe temperature range, and prevent damage or failure caused by overheating. Through this automatic control mechanism, the thermostat provides reliable safety protection for the device.
