Environmental Testing for Electrical Equipment

Introduction:

Periodic inspections or tests conducted on operational equipment according to specified test conditions (such as designated test equipment, environmental conditions, test methods, and test voltages, etc.), test items, and test cycles, to identify hidden issues in power equipment during operation and prevent accidents or equipment damage. It is an important measure to determine whether power equipment can continue to operate safely and ensure secure operation.

Equipment Parameters:

Laboratory Dimensions: 22m × 22m × 27m (L × W × H)

Temperature Range: -40°C to 60°C, uniformity ≤ 2°C

Humidity Range: 40%RH to 95%RH, control accuracy ≤ ±5%RH

Wind Speed: 0 to 10m/s, measurement accuracy ±0.2m/s

Rainfall: 0 to 120mm/h, both horizontal and vertical directions

Icing: 0 to 5mm/h, capable of achieving three icing states: glaze, rime, and mixed icing

Pollution: Fills the entire space within 30 minutes (cold fog, hot fog)

Clean Fog System: Uses artificial solid contamination coating method, with clean fog added to complete pollution tests
