AC Distribution Switchgear Panel

1.Overview

GGD ac distribution switchgear panel is suitable for power users in power plants, substations, industrial enterprises and other power distribution systems with AC 50 Hz, rated voltage 380 v, and rated current 3200 A. It is used for the conversion, distribution and distribution of electricity, lighting and electrical energy. Control the power distribution unit.

2. Electrical performance

Basic electrical parameters:

Rated voltage: 380 volts

Rated current: 400-3200 A

Destruction capacity: RMS (kA): 15 to 50

Peak value (kA): 30-105

3. Performance characteristics

Novel and reasonable structure, safe power distribution, and practical electrical design;

High breaking capacity, good dynamic thermal stability, strong adaptability;

High protection level;

Executive standard: GB/T4048-1993 IEC947-1: 1998 GB7251. 1-1997 IEC439-1: 1992

4. Normal use conditions

1) The ambient temperature is not higher than + 40 °C, not lower than 5 °C; not higher than the average temperature within 24 h + 35 °C. Indoor installation, use site altitude 2000 m.

2) The relative humidity of the ambient air at the highest gradient is not greater than 5.

3) The equipment should be installed in a place where there is no severe vibration, and the temperature does not exceed 50% to +40°C. At low temperatures, the allowable relative humidity is relatively large (for example, +20°C is 90%), and temperature changes should be considered. Accidental condensation effect.

4) Install vertical and impact equipment, and place insufficient electrical components to prevent corrosion.

5) The user has special requirements to resolve with the factory.
