Product Overview & Application Scenarios
The HMGY-800 Switchgear Power-On Test Bench is designed for factory commissioning of high and low voltage switchgear by manufacturers. It can also serve as a replacement for on-site DC operating power supplies during substation maintenance and in other applications requiring DC power. In power plants, substations, switchgear factories, and similar facilities, both primary and secondary equipment are critical. These components form an integrated system, and only when both are in optimal condition can the safety of power generation be assured.
Application Scenarios
1. Manufacturing Quality Control (Factory Acceptance Test - FAT): Each new switchgear panel must undergo testing on a test bench prior to shipment.
2. New Substation or Facility Commissioning: All installed switchgear must be tested before energizing new factories, data centers, or substations.
3. Preventive Maintenance and Fault Diagnosis: After reaching specified operational cycles (e.g., annually), switchgear power is disconnected for testing to ensure normal operation under fault conditions.
4. Repair and Refurbishment Validation: Following maintenance or replacement of components such as circuit breakers or relays, the entire assembly must undergo testing to confirm performance meets original specifications.

Additional Features
1. Integrated Testing Capabilities:
Primary Injection Test: Applies high current (up to 2000A or more) to test the entire current path, including circuit breakers and busbars.
Secondary Injection Test: Simulates fault conditions to calibrate and verify protection relays (overcurrent, earth fault) without high power.
Contact Resistance Measurement: Uses a micro-ohmmeter to find loose or worn connections.
Circuit Breaker Timing Analysis: Measures how fast the breaker opens and closes.
Dielectric Withstand (Hi-Pot) Test: Checks the strength of insulation.
2.Advanced Safety & Protection Systems:
Emergency Stop Buttons: Instantly cut power in case of danger.
Automatic Discharge: Safely discharges stored electrical energy after a test.
Safety Interlocks: Prevents operation if a safety guard is open or a connection is wrong.
Over-current & Over-voltage Protection: Shields the test bench from damage.
3. Automated Operation & User-Friendly Interface:
Touchscreen HMI (Human-Machine Interface): Allows easy setup and control of tests.
Pre-programmed Test Modules: Operators can select a test ("CB Timing") with built-in parameters.
Automatic Sequencing: Runs a series of tests ( close-open-time-resistance) automatically.
4. Data Management and Reporting:
Internal Data Storage: Saves test results for many units.
USB/Network Export: Allows data transfer to a computer.
Automated Report Generation: Creates standardized test certificates (PDF reports) for quality records and compliance.
