introduce
GCS low voltage draw-out switch cabinet (hereinafter referred to as device) Currently this device has been widely adopted by power consumers and it is applicable to the power distribution system of power station, petroleum, chemical engineering, metallurgy, textile, high-rise building and other fields. The device applies to highly automatic places with computer interface such as large power stations and petrochemical systems which employ low-voltage power distribution device for power distribution of the power generation and distribution system, centralized control over generator and reactive power compensation with three-phase AC frequency 50 (60) Hz, rated operational voltage 380 (400) V, (600) V and rated current of no more than 4000A. Working conditions
1. The ambient air temperature shall be no higher than +40 and no lower than -5¡æ. The average temperature within 24 hours shall be no higher than +35¡æ.
2. The device shall be applied indoors, the elevation of which shall be no higher than 2000m.
3. Relative humidity of the ambient air shall be no more than 50% when the maximum temperature is +40¡æ; higher relative humidity is allowable in lower temperatures. For example, in case of 90%’s humidity during +20¡æ, occasional condensation resulting from temperature change shall be taken into account.
4. The device shall be vertical during installation for fear the gradient is no more than 50°.
5. The device shall be installed at place without violent vibration and shock and place that will not cause corrosion to the electronic components.
