HYIC3X
Series of Intelligent Integrated Anti-harmonic Power Capacitor Compensation Devices
Application Scope
The HYIC3X series intelligent integrated anti-harmonic power capacitor compensation device utilizes lowvoltage power capacitors as its core, integrating advanced technologies such as modern measurement and
control, power electronics, network communications, and automated control. It replaces traditional reactive
power compensation devices, which consist of separate components such as controllers, fuses, combination
switches or mechanical contactors, thermal relays, low-voltage capacitors, and indicator lights, all connected by
wires within a cabinet.
This intelligent anti-harmonic low-voltage capacitor is primarily used for reactive power compensation in
applications with severe harmonics. It operates reliably, does not resonate, does not amplify harmonics, and can
absorb and eliminate them to a certain extent. The device with a 7% series reactor is suitable for electrical
environments where the dominant harmonic is the fifth harmonic, while the device with a 14% series reactor is
suitable for electrical environments where the dominant harmonic is the third harmonic.
Compliant standard: GB/T 15576, \"Low-voltage Complete Reactive Power Compensation Device.\"

inrush current, overvoltage, or arcing.
3. Protection
Features overvoltage, undervoltage, power loss, short-circuit, and over-temperature protection. Internal
temperature protection shuts down the unit if it overheats, extending service life.
4. Control Technology
Switching is based on power factor and reactive power, using predictive and delayed sampling to ensure stable,
oscillation-free compensation, even under heavy loads.
5. Intelligent Networking
Supports standalone or networked operation. Faulty units automatically exit without affecting the system. RS-485
communication enables automatic master-slave networking for reliable operation.

HYIC3-K
Series Reactive Power Automatic Compensation Controller
Application Scope
The HYIC3-K reactive power compensation controller, used in conjunction with the HYIC3 series intelligent lowvoltage capacitors, collects and displays electrical measurement data, including statistics on maximum reactive
power shortages and peak voltages. It also statistically stores data such as power factor, active power, reactive
power, and operating events before and after compensation. It monitors and displays the operating conditions
and switching status of the intelligent capacitors, including capacitor voltage, current, temperature, and
capacitor unit number. It also allows for manual capacitor switching and automatic switching of electromagnetic
zero-crossing capacitors based on reactive power and target power factor.
Structural Features
1. Storage function: It can store the maximum, minimum, and average (once daily) values of the three-phase
power factor, active power, and reactive power data before and after compensation, as well as device
operating events.
2. The controller and capacitors form an intelligent, automatic network. If a controller sampling failure occurs, the
intelligent capacitor network automatically becomes the master and performs compensation, preventing loss
of reactive power compensation due to controller failure.
3. The controller analyzes each branch capacitor, including its properties, switching status, compensation
current, and real-time temperature.
4. It communicates with external maintenance equipment via an RS-485 interface.
5. Data can be downloaded via a USB port and viewed on a PC.

HYFK
Series Low Voltage Compound Switch
Application Scope The HYFK combination switch consists of three independent combination switches with a rated operating voltage of AC380V, 220V±20%, suitable for on-off control of low-voltage reactive compensation capacitor banks. The basic operating principle of the combination switch is to connect a thyristor (SCR) in parallel with a magnetic latching relay. This combination switch combines the advantages of SCR zero-crossing switching during the switching on and off phases with the power-saving advantages of a contactor switch during normal switching. This product complies with GB 14048.4-2010, Low-Voltage Switchgear and Controlgear, Part 4-1: Contactors and Electric Starters (Electromechanical Contactors and Motor Starters (Including Motor Protectors)).
Load side Power Supply Side Distribution Primary Current Low-voltage Reactive Power Compensation Controller Split-compensation Intelligent Capacitor Split-compensation Intelligent Capacitor Split-compensation Intelligent Capacitor
Structural Characteristics 1. Zero-crossing switching: The HYFK composite switch is a combination of intelligent chips, digital circuits, and magnetic latching relays to achieve voltage zero-crossing conduction and current zero-crossing disconnection, so that the switch can completely cross zero-crossing switching at the moment of connection and disconnection without generating overvoltage. The switch has many advantages such as no inrush current, extremely low power consumption, long life, and low failure rate, and is widely used in the field of low-voltage reactive power compensation. 2. Protection function: The microprocessor is used to monitor the operating conditions of the switch relay, input power supply, and load, and has perfect protection functions.
(1) Grid overvoltage and undervoltage protection: When overvoltage or undervoltage occurs,
it will automatically disconnect and the power light will flash to warn;
(2) Phase loss protection: When any phase is lost, it will automatically disconnect and the power light will flash
to warn;
(3) Power failure protection: If a sudden power failure occurs after connection, it will automatically disconnect;
(4) No-load protection: When no load is connected, it will refuse to close and the indicator light will flash to
warn; the split-compensation composite switch will continuously cycle to detect the phase, and the
indicator light will scan and flash in a cycle.
(5) Phase indicator switch status: Power light, long on for normal; flashing for overvoltage, undervoltage or
phase loss; A/B/C phase status light, long on for switch closed; flashing for a phase for a phase fault, or
a phase capacitor is in the discharge delay;
(6) Self-diagnosis fault: If any phase fails, the switch will refuse to operate and the indicator light will flash as
a warning; 3. The composite switch does not need to be connected to the neutral line (N line); 4. Low power consumption: The magnetic latching relay consumes power only at the moment of switching, and consumes almost no power at other times, thus achieving energy saving and consumption reduction; 5. Auxiliary contacts with switch status feedback are available to facilitate the controller to collect the online status of the composite switch; 6. Working safety: All control input signals are safely isolated from the internal circuit: At the same time, it adopts advanced intelligent control technology, and has extremely high performance advantages in inrush current and safety reliability compared with similar products. The input signal is optically isolated from the composite switch, with high EMC protection measures and strong anti-interference ability: It works safely and reliably.

Series Low-Voltage Reactor
Application Scope
When compensating for capacitive reactive power, capacitors are often affected by harmonic currents, closing
inrush currents, and operational overvoltages, causing damage to the capacitors and reducing the power factor.
Therefore, it is necessary to install a series reactor in front of the capacitor to suppress and absorb harmonics
and protect the capacitor from the influence of harmonic voltage and current and impact voltage and current,
improve power quality, increase system power factor, extend capacitor life, and ensure safe operation of the
power grid.
Structural Characteristics
Main Technical Parameters
1. Applicable capacitor voltages: 0.4kV, 0.45kV, 0.4BkV, 0.525V, 0.66kV, 0.69kV.
2. Reactance: 1%, 4.5%, 5%, 5.67%, 6%, 7%, 12%, 13.8%, 14%.
3. Withstand voltage: 5kV/min, insulation grades: B, F, H, noise ≤ 30dB, overload capacity ≤ 1.35 times continuous
operation.
4. Installing a series reactor causes a system voltage increase. The calculation formula is: Ug = ( ) X Un
(Capacitor bank operating voltage: Ug; System rated operating voltage: Un; Reactor tuning times: n)
5. The conversion formulas for reactor capacity, capacitance, reactance, and inductance are: UL = Uc
phase x L =
(Capacitor capacity: Qc; Reactor capacity: Qw; Reactor terminal voltage: UL)
Inductance: L; Reactor current: I; Capacitor phase voltage: Uc phase; Qw = Qc phase x Reactance ratio =

punch press. This results in minimal burrs, uniform lamination, and neat and beautiful lamination, ensuring low
temperature rise and low noise during operation.
3. The coil utilizes high-quality insulated wire and is wound by a dedicated machine, resulting in excellent
flatness and an attractive appearance.
4. During the reactor assembly process, all clamps undergo corrosion protection treatment, and key clamps are
made of non-magnetic materials. A pre-baking, vacuum impregnation, and heat curing process ensures that
the reactor coil and iron core are firmly integrated. This significantly reduces temperature rise and noise during
operation, effectively improving the reactor's quality factor and reducing harmonics.
5. The reactor's dimensions are designed based on standard cabinet dimensions, resulting in a compact size,
convenient wiring, and significant savings in cabinet investment.
Usage Environment
1. Altitude not exceeding 2000 meters.
2. Operating ambient temperature -25°C to 45°C, relative humidity not exceeding 90°C.
3. The surrounding area must be free of harmful gases and flammable or explosive materials.
4. The surrounding environment must have good ventilation. If installed in a cabinet, ventilation equipment must
be installed.
