Profile:

The KDCJ-1800kV/180kJ is a 9-stage impulse generator (180kJ total energy) for standard lightning (1.2/50μs) and switching (250/2500μs) impulse tests on insulators, bushings, and transformers. It delivers >85% efficiency for lightning impulses, precise control (15%-100%Un ignition range), and continuous operation below 70% rated voltage. Compliant with GB/IEC standards, it ensures reliable, repeatable results for high-voltage insulation verification.

Features:

  • High Voltage & Energy Capacity: Nominal voltage of 1800kV and total energy of 180kJ, suitable for large-scale high-voltage equipment testing.
  • Compliant Waveforms: Generates standard lightning impulse full-wave (1.2/50μs) and switching impulse (250/2500μs) waveforms, with parameters and deviations meeting GB311 and GB16927 standards.
  • High Efficiency: Achieves >85% efficiency for lightning impulses (load) and >70% for switching impulses (load), optimizing energy usage.
  • Precise Control: Ignition range of 15%-100%Un and synchronization step discharge control rate <2% for accurate and repeatable tests.
  • Continuous Operation: Can run continuously below 70% rated voltage, and after 120s charge-discharge cycles above 70% rated voltage.
  • Reliable Construction: 9-stage design with 18 single-stage pulse capacitors (2F/100kV), ensuring stable and durable performance.
  • Standard Compliance: Meets GB/T 3111.1, GB/T 16927.1, GB/T 16927.2, GB/T 16896.1, GB/T 7449, JB/T 7616, DL/T 557, and ZBF 24001 standards.
