LQ610 DC High-Voltage Generator

*Arrester & Cable Testing | GB 11032-89 Compliant | Field-Ready Reliability*

Engineered for Critical DC Withstand Tests

The LQ610 is a next-generation DC HV generator designed for voltage withstand testing and leakage current measurement of metal-oxide arresters (MOA), power cables, and high-voltage equipment. Fully compliant with China's GB 11032-89 standard for no-gap ZnO arresters, it replaces legacy systems with advanced safety and portability.

Key Technical Innovations

Technical Specifications

Compliance & Applications

Standards Met

• GB 11032-89: No-gap metal oxide arresters

• DL/T 474.4-2018: DC withstand test procedures

• IEC 60060-1: HV test techniques

Critical Tests Performed

Workflow: Arrester Testing Example

1. Connect

• Clip HV lead to arrester top terminal

• Ground base plate

2. Program

• Set Uₘₐₓ (e.g., 100kV for 110kV arrester)

• Enable 0.75U₁ (75kV auto-capture)

3. Ramp

• Increase voltage to Uₘₐₓ at 1kV/s

4. Hold

• 10-minute timer starts (audible alert at end)

5. Analyze

• Record leakage current at 0.75U₁ (acceptance: <500μA)

Safety Systems

• Zero-Start Interlock
  Prevents energization if control knob ≠ "0"

• Emergency Cutoff
  <0.1ms shutdown on arc detection

• Automatic Discharge
  Bleeds stored energy to <5V after test

• Dual Grounding
  Redundant earth terminals (EN 50191)
