Thyristor switch

Silicon-controlled rectifier and relay parallel‑connection design, with millisecond‑level fast response, anti‑interference capability, zero‑crossing switching, and noiseless operation. Current rating ≥ 2.5 times the capacitor current; low losses and minimal inrush current. A 55K fan is controlled by an 80K over‑temperature protection circuit.

Controller

4.3-inch touch screen, capacitive characteristic analysis curves for each branch circuit, graphical analysis functions, real-time temperature monitoring, switching cycle counting, operating time analysis, capacitor degradation assessment, and resonance monitoring.

Capacitive reactance

Low-voltage series reactors, self-healing low-voltage shunt capacitors, dry-type iron-core reactors, polypropylene metallized film dielectrics, harmonic suppression and protection capacitors, with excellent self-healing characteristics. For branch compensation, a three-phase five‑column design is employed; continuous operation at 1.1 times the rated voltage; low noise and minimal losses; short‑time operation at 1.3 times the rated voltage; temperature rise ≤ 60 K, noise level ≤ 48 dB, and heat resistance class H.
