Product Overview – KDGK-II High & Low Voltage Switchgear Power-On Test Bench

The KDGK-II High and Low Voltage Switchgear Power-On Test Bench is specifically designed for manufacturers of high and low voltage switchgear to perform comprehensive power-on acceptance tests before product dispatch. It provides a versatile range of adjustable and fixed AC/DC power outputs, enabling efficient and reliable functional verification of switchgear units and significantly improving production line testing efficiency.

Key Features:

• Integrates a fully controlled three-phase rectifier module, phase-shift triggering circuit, automatic regulation system, and absorption circuit.
• Employs an intelligent transistor control module that combines complex regulation circuitry, thyristors, and trigger circuits into a compact, unified unit. Output voltage is precisely controlled by adjusting the control signal, which varies the thyristor conduction angle.
• The triggering circuit, thyristors, and heat-conducting baseplate are mutually insulated, with a dielectric strength exceeding 2,500 V, ensuring safe and reliable operation.
• Input phase sequence insensitive—simplifies installation and use.
• Compatible with both resistive and inductive loads.

Technical Specifications:

• Input Power: Three-phase four-wire AC 380 V
• Output Capabilities:
  1. Adjustable three-phase four-wire AC voltage: 0–380 V (1 set)
  2. Adjustable three-phase AC current: 0–10 A (1 set)
  3. Adjustable DC operating voltage: 0–260 V (1 set)
  4. Fixed three-phase AC voltage: 100 V (1 set)
  5. Fixed DC outputs: 24 V, 36 V, 110 V, 220 V (1 set)
  6. Fixed three-phase AC output: 380 V (1 set)
  7. Fixed single-phase AC output: 220 V (1 set)
• Dimensions: 700 × 600 × 1100 mm (W × D × H)

Typical Application Environment:
Ideal for use in switchgear manufacturing workshops, assembly lines, and final inspection areas. The KDGK-II supports full functional testing of common switchgear types (e.g., GGD, GCS, MNS, KYN28) under simulated real-world power conditions. Its robust design, electrical safety features, and flexible power outputs make it a reliable solution for standardized, high-efficiency factory acceptance testing in industrial settings.
