Comprehensive Structural Design Check-up
Certification is like giving equipment a full-body check-up; structural assessment is the first step:
Enclosure Protection: Dust and water resistance testing to ensure outdoor safety.
Internal Layout: Checking the rationality of component spacing to avoid poor heat dissipation.
Material Testing: Verifying the flame retardancy of non-metallic parts to prevent the spread of fire.
Labeling Verification: Confirming the clarity of warning signs, wiring diagrams, and other graphics.
Practical Performance Testing
Equipment must undergo high-intensity testing like an athlete:
Temperature Rise Test: 4 hours of full-load operation; critical component temperatures must not exceed limits.
Short Circuit Verification: Simulating sudden short circuits to ensure timely activation of protection devices.
Operating Life: Mechanical components must withstand tens of thousands of repeated operations.
Insulation Testing: Leakage current controlled within safe limits under high-voltage environments.
Dual Safety Protection
The final checkpoint focuses on dual protection for personnel and equipment:
Electric Shock Protection Design: Voltage at touchable points must be below safe values.
Arc Protection: Effectively controlling arc propagation in case of internal faults.
Grounding System: Grounding continuity testing of all metal components.
Emergency Function: Response time measurement of emergency disconnection devices.
