★ Scope of use
GCS series switchgear is suitable for industrial and mining enterprises. The three-phase AC frequency is 50HZ, and the fixed frequency voltage is 380V to 360V. The primary power distribution of the power system and the secondary power distribution or control equipment with asynchronous motor as the main control object are also suitable for stations. Terminals, high-rise buildings are particularly suitable for field control devices of power plant, substation, petroleum, chemical, metallurgical, mechanical group control systems, power, distribution and motor control centers, capacitors of low-voltage power distribution systems such as stone enterprises, high-rise buildings, and capacitors. The compensated electrical energy conversion is allocated for control.
In a large-unit power plant, it can meet the special needs of computer interfaces in low-voltage power control centers and motor control centers such as large-scale petrochemical industries.
The product has the characteristics of strong breaking, high connection capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series practicability, novel structure and high protection level. It can be used as a replacement product of low-voltage withdrawable switchgear.
★ Conditions of use
1. The ambient air temperature is not higher than + 40 ° C, not lower than -5 ° C, and the average temperature within 24 hours must not be higher than + 35 ° C. When exceeding, it is necessary to drop passengers according to the actual situation.
2. For indoor use, the altitude of the place of use must not exceed 2000m
3. The relative humidity of the surrounding air does not exceed 50% at a higher temperature of + 40 ° C, and a larger relative humidity is allowed at a lower temperature, such as + 20 ° C is 90%. It should be considered that the temperature may change due to temperature changes. Occasionally condensed.
4. The inclination between GCS and vertical should not exceed 50%, and the entire cabinet row should be relatively flat.
5. The GCS is installed in a place where there is no severe vibration and impact and is insufficient so that the electrical components are subject to undue corrosion.
