Knowledge Base

Frequently Asked Technical Questions

Clarifying operational, thermal, and mechanical parameters for EPC specifiers and engineering procurement managers.

❓ How do DC regulators and breakers handle DC arc extinction compared to AC systems?
Unlike alternating current which passes through a natural voltage zero point every half-cycle, continuous direct current sustains an intense electrical arc upon contact separation. Our equipment integrates high-strength magnetic blowout coils, deep de-ionizing arc chute splitters, and vacuum arc extinguishing chambers (VS1 series) to rapidly stretch, cool, and extinguish DC arcs within milliseconds, preventing terminal damage.
❓ Can standard AC switchgear enclosures be customized for high-voltage DC busbars?
Yes. We re-engineer the internal busbar geometry, clearance spacing, and creepage distances to avoid ion migration. Special polymer insulators and reinforced air/gas barriers are incorporated to handle continuous unidirectional electric fields, with optional solid-insulation schemes (such as the GXGN-12 series) eliminating partial discharge phenomena completely.
❓ What role do on-load tap changer transformers play in regulated industrial lines?
Units like our SZ11/SFZ11 35kV series dynamically adjust secondary AC voltage levels while under load, counteracting primary grid voltage sags or industrial motor surges. When placed upstream of high-power thyristor or diode rectifiers, they stabilize the input AC rail, significantly reducing the duty cycle stress on downstream DC solid-state regulating stages.
❓ What documentation is required for custom OEM manufacturing quotations?
To deliver an accurate design and commercial quotation, please provide your Single-Line Diagram (SLD), rated system operational and impulse withstand voltage, expected short-circuit interruption capacity (Icu/Ics), ambient altitude and humidity specifications, preferred enclosure ingress protection (IP) rating, and required auxiliary control voltages (e.g., 24VDC, 110VDC, or 220VAC).
