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 provides over‑temperature protection at 80K.

Controller

4.3-inch touch screen, capacitive characteristic analysis curves for each branch circuit, graphical analysis functions, real-time temperature monitoring, switching cycle count and 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, and polypropylene metallized film dielectrics—designed to suppress harmonics and provide protective capacitance—with excellent self-healing characteristics. For branch compensation, a three-phase five‑column configuration is employed, enabling continuous operation at 1.1 times the rated voltage with low noise and minimal losses, and short‑time operation at 1.3 times the rated voltage. Temperature rise is limited to ≤60 K, noise levels are ≤48 dB, and the insulation class is H.
