1500V Supercapacitor Cluster Discharge Resistor Cabinet – Safe 30-Min Continuous Discharge for 1000V~2000V Supercapacitor Systems

If you’re engaged in supercapacitor energy storage testing and maintenance, safe residual power release after equipment shutdown has always been a major safety concern. Conventional discharge equipment cannot sustain long-time high-current operation, which easily leads to hidden dangers such as overheating and short circuits. Our newly launched DC discharge resistor cabinet is specially customized for 1000V~2000V, 1F~20F supercapacitor clusters, dedicated to residual power discharge during supercapacitor maintenance, testing and shutdown, realizing safe, controllable and stable discharge of supercapacitor systems.

Core Electrical Performance

The cabinet is equipped with an internal DC circuit breaker with withstand voltage ≥4000V DC and rated long-term current up to 200A. It supports continuous discharge for more than 30 minutes, with constant resistance current limiting, and the operating current is always controlled below 200A without impact or overcurrent risks. Built-in DC voltmeter and ammeter enable real-time online monitoring of voltage and current, with complete traceable operation data. Large-power external wiring terminals are reserved to meet the demand of long-term high-current discharge.

Mobile Cabinet Structure & Heat Dissipation Design

The cabinet is made of high-quality cold-rolled steel plate with electrostatic plastic spraying, rust-proof and corrosion-resistant, with IP20 protection grade, suitable for indoor testing and maintenance scenarios. Brake-equipped universal casters are installed at the bottom, which can be moved freely and fixed at any working position. The heat dissipation system adopts double-side ventilation ducts plus top exhaust, matched with forced air cooling fans to ensure stable heat dissipation during long-time discharge. Humanized safety structures are fully equipped: cabinet door lock, internal insulation baffle, anti-miscontact structure and special grounding terminal. Overall dimension: Width 950±3mm, Depth 550±3mm, Height 800±3mm.

Comprehensive Multi-Layer Safety Protection

1. Insulation withstand standard: The withstand voltage between live parts and cabinet shell reaches 4kV AC/1min, no breakdown or flashover; cabinet grounding resistance ≤4Ω.

2. All-round protection mechanism: Short-circuit protection, overload protection, over-temperature protection, grounding protection and insulation protection are integrated.

3. Overheating prevention design: High temperature early warning and automatic power-off function to avoid fire risks caused by resistor overheating.

4. Anti-misoperation design: Anti-short circuit, anti-reverse connection and anti-wrong operation structures are adopted. Every cabinet will complete full-voltage and full-load discharge tests before delivery, and can be delivered only after passing all performance standards.

Clear Operation Panel Layout

The front panel integrates all monitoring and control components for easy operation:

· 1500V DC voltmeter, temperature display (support customizable upper and lower temperature limits)

· Main circuit closing indicator, temperature sound-light alarm, fan running indicator

· Contactor switch, independent fan switch, 300A large current terminals, auxiliary circuit aviation socket

Suitable Application Scenarios

Energy storage test stations, new energy laboratories, power equipment maintenance workshops with 1000V~2000V, 1F-20F supercapacitor cluster systems. It is the ideal discharge equipment for daily overhaul and experimental testing of supercapacitor equipment.
