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.

KD2675 Power Frequency AC Withstand Voltage Testing Equipment for High Voltage Cables

The AC Withstand Voltage Test Device is widely used in power system equipment testing, including transformers, switchgear, insulators, bushings, cables, and electrical components. Its intuitive 7-inch touch screen (optional 10-inch), fully digital calibration, and automatic/manual test modes make it suitable for both field and laboratory environments.

With real-time display of voltage, current, and status, as well as intelligent safety reminders and result judgment, the device ensures fast and accurate dielectric strength tests. It is ideal for:

  • Factory routine testing of high-voltage apparatus

  • On-site commissioning of substations and power stations

  • Preventive maintenance in power grid companies

  • R&D and lab testing in electrical equipment manufacturing

  • High-voltage insulation performance validation after repairs or overhauls

The system enhances safety and efficiency with voice alarms, flashing high-voltage warnings, password-protected settings, and multi-device compatibility, offering a modern solution for high-voltage withstand testing needs.
