The device has been widely used by power users. The device is suitable for power plant, petroleum, chemical, metallurgy, textile, high-rise building and other industries of power distribution system. In large power plants, petrochemical systems and other places with a high degree of automation and requiring computer interface, As a three-phase AC frequency of 50(60)Hz, rated operating voltage of 380(400, 660)V, rated current of 4000A and below in the power supply system, power distribution, motor centralized control, reactive power compensation for use in low-voltage power distribution devices designed to meet the following standards :IEC439-1 low-voltage switchgear and control equipment GB 7251 Low voltage switchgear JB/T9661 Low voltage withdrawable switchgear
Ambient air temperature is not higher than +40ºC, not lower than -5ºC. The average temperature within 24 hours must not be higher than +35 ° C. If it is higher than +35 ° C, reduce the operating capacity according to the actual conditions.
For indoor use, the altitude of the use place shall not exceed 2000m.
The relative humidity of the surrounding air does not exceed 50% at the maximum temperature of +40 ° C, and a larger relative humidity is allowed at lower temperatures: such as 90% at +20 ° C, the effect of condensation that may occur occasionally due to changes in temperature should be taken into account.
The tilt of the vertical plane when the device is installed does not exceed 5%, and the whole set of cabinets is relatively flat (in line with GBJ232-90 standard).
The device shall be installed in a place free from violent vibration and shock and insufficient to cause undue corrosion of electrical components.
When the user has special requirements, it can be negotiated with the manufacturer.
The capacitor compensation cabinet is designed
Reactive power compensation is used
