Filter compensation device for welding machines

The low-voltage dynamic reactive power compensation device employs safe, high‑efficiency, intelligent dynamic filtering and compensation modules, with switching strategies that include a cyclic mode (first‑in‑first‑out), a linear mode (first‑in‑first‑out), and a fast mode (20 ms). Each circuit branch is equipped with independent protection features, including harmonic protection, overcurrent protection, overtemperature protection, phase‑loss protection, and instantaneous trip protection, thereby providing maximum assurance for the safe operation of the power supply system. The low-voltage dynamic reactive power compensation device delivers rapid reactive power compensation, improving the system power factor, enhancing grid transmission capacity, and reducing line losses; it also increases equipment utilization, minimizes mechanical wear; stabilizes voltage and reduces voltage fluctuations; and absorbs harmonics, mitigating their impact on the power grid.

Fast-acting vacuum circuit breaker

Fast-acting vacuum circuit breaker

During a short-circuit fault: the fast‑acting vacuum circuit breaker rapidly discharges the energy stored in its energy‑storage capacitor, and the electromagnetic repulsive force generated by eddy currents directly drives the breaker to achieve rapid opening. It can detect a short-circuit fault within 2 ms and complete opening within 4 ms after receiving the command, enabling it to interrupt the fault during the initial phase of the short‑circuit current, thereby preventing overreaching tripping of upstream switches. The trip‑current threshold is customizable. In the absence of a fault: the fast‑acting vacuum circuit breaker is fully compatible with conventional medium‑voltage circuit breakers in terms of operating procedures, physical dimensions, and wiring configurations. It can detect a short-circuit fault within 2 ms and complete opening within 4 ms after receiving the command, allowing it to interrupt the fault during the first peak of the short‑circuit current and preventing overreaching tripping of upstream switches. The trip‑current threshold is also configurable.

Wall-Mounted Active Power Filter Compensation Module

Wall-Mounted Active Power Filter Compensation Module

The active filtering compensation module is a modular product specially developed by Guangda Electric for dynamic harmonic mitigation in 0.4 kV power supply systems. Connected in parallel with the grid, it uses an external current transformer to continuously monitor the load current. Leveraging DSP, FPGA, and CPLD chips, along with cutting-edge rapid harmonic mitigation and reactive power extraction technologies, it swiftly analyzes the harmonic and reactive components of the load current. Based on user-defined setpoints, it generates PWM pulses to drive a bidirectional converter composed of three-level IGBT modules, thereby producing compensation currents that meet grid requirements. This enables precise, real-time compensation of harmonic and reactive currents, ultimately enhancing power quality. Active modular power quality products comprise three categories: static var generators (SVG), three-phase unbalance compensators (ASVG), and active filters (APF).
