Arc Chamber
HAIPART
3012052
Unlike AC circuits where arcs naturally extinguish at current zero-crossings, direct current (DC) interruption presents extreme physical challenges with sustained high-energy plasma arcs. The 3012052 DC ACB Arc Chamber is specifically developed for high-voltage, high-current DC switchgear, delivering rapid arc stretching, forced cooling, and high counter-voltage generation.
Featuring an ultra-dense array of 41 de-ion splitter plates made from high-permeability DC01 cold-rolled steel and bonded by rigid, non-tracking melamine glass cloth boards, this arc chute provides the decisive breaking capability required for critical DC power infrastructures.
| Product Part Number | 3012052 (DC ACB De-ion Arc Chute) |
| Structural Configuration | 41 De-ion Splitter Plates + 2 Heavy-Duty Support Boards |
| Grid Plate Material | DC01 Cold-Rolled Strip Steel (High magnetic saturation & optimal thermal dissipation) |
| Surface Treatment | 2μm Precision Nickel Electroplating (Anti-oxidation, arc ablation resistant) |
| Insulation Support Plate | Melamine Glass Cloth Board (Zero carbon tracking, extreme structural rigidity under burst pressure) |
41-Stage Voltage Multiplication: Because DC arcs lack natural zeros, extinction depends on building an arc voltage higher than the DC bus voltage. The 41-plate design divides the high-energy DC arc into 42 series micro-arcs, rapidly multiplying near-electrode voltage drops to force current limitation.
High Magnetic Drive: High-purity DC01 steel provides high magnetic saturation, generating a powerful Lorentz driving force that rapidly pulls the arc column from breaker contacts deep into the chamber.
Thermal Ablation Resistance: High-density 2μm nickel plating prevents metal spatter and plate bridging during repeated high-energy DC breaking operations.
Shock & Arc Tracking Immunity: The thermoset melamine glass cloth boards maintain tight plate spacing tolerances under violent magnetic blowout pulses, eliminating internal conductive tracking.
Specially engineered for utility-scale and industrial DC distribution networks:
Solar PV combiner and central inverter DC incoming panels
Utility-scale Battery Energy Storage Systems (BESS) DC switchgear
Urban rail transit, metro traction power substations, and DC railway feeding
Industrial DC microgrids, marine propulsion, and heavy DC mining equipment
Q1: Why does a DC arc chamber require up to 41 splitter plates?
A1: DC current has no natural zero-crossing. The only way to extinguish a high-voltage DC arc is to build an arc voltage ($V_{arc}$) greater than the system DC voltage ($V_{sys}$). 41 plates create 42 series short arcs, establishing a massive cumulative electrode voltage drop to choke fault current.
Q2: What role does Melamine Glass Cloth Board play in high-voltage DC applications?
A2: Under sustained DC arc thermal radiation, conventional polymers carbonize and create conductive short-circuit paths. Melamine glass cloth laminate provides exceptional Comparative Tracking Index (CTI) ratings and structural rigidity, ensuring long-term dielectric reliability.
Q3: Can HAIPART customize DC arc chutes for energy storage and traction systems?
A3: Yes. We offer customized plate geometries, runner configurations, magnetic blowout enhancements, and bespoke mounting structures tailored to your breaker frame sizes.
