Description

The GCK type low-voltage withdrawable switchgear is mainly composed of a distribution center, a motor control center, and functional units. These units are installed in a closed metal cabinet in a sequential manner, and the horizontal busbar on the upper part of the cabinet connects the cabinets together; The functional units of the unified cabinet are connected in parallel on the vertical busbar, and the cabinet is divided into four mutually isolated areas: horizontal busbar area, vertical busbar area, cable area, and equipment installation area. Functional units are installed in small rooms at various locations within the equipment area. In the event of an accident, the power supply of each functional unit can be quickly cut off (in order to replace the backup functional unit), without affecting the normal operation of other functional units, which can prevent the expansion of the accident.

This product is equipped with a complete and reliable grounding system and electrical protection, and all functional units can break short-circuit current according to the specified performance. The incoming unit has four protection features, which can ensure the reliability of power supply and the safety of equipment and systems.

The altitude of the usage location shall not exceed 1000m;

The ambient air temperature shall not exceed+50 ℃, not be lower than -5 ℃, and the average temperature within 24 hours shall not exceed+35 ℃. Under storage and transportation conditions, the temperature shall be between -25 ° C and+55 ° C, and shall not exceed 70 ℃ for a short period of time;

The monthly average relative humidity is not greater than 95%. At lower temperatures, a larger relative temperature is allowed, and at+25C, a relative temperature of 90% is allowed. The design of the switchgear has taken into account the occasional condensation phenomenon. If required, temperature and humidity controllers as well as heating and dehumidification devices can be installed in the switchgear to prevent condensation;

The seismic intensity shall not exceed 8 degrees. Horizontal acceleration ≤ 0.5g, vertical acceleration ≤ 0.3g;

Vibration amplitude: When F<10Hz, the amplitude is not greater than 0.3mm; when 10Hz<F<150Hz, the acceleration is not greater than 0.1g;

The installation inclination of the switchgear shall not exceed 5 °, and it shall be installed indoors.

Pollution level: 3.
