PRODUCT  INTRODUCTION:

In large power plants,petrochemical systems and otherhigh degree of automation,requiring the interface with the computer,as a three-phase AC frequency of 50(60)Hz,rated operating voltage of 400V,660V,rated current of5000A and below the power supply system in the distribution,motor centralized control,reactive power compensation of the use of low-voltage complete sets of distribution devices.

The design of the device conforms to the following standards:IEC439-1"Low-voltage switchgear and control equipment" GB7251 "low-voltage switchgear".

WORKING  CONDITION:
◇The ambient airtemperature shall not be higher than +40℃,not lower than -5℃,and the average temperature shall not be higher than +35℃ within 24 hours.In case of excess,capacity should be reduced according to the actual situation.
◇Indooruse,the altitude of the use place shall not exceed 2000m; The  relative  humidity  of  the  surrounding  air  does  not  exceed  50%when  the  maximum  temperature  is+40°C,and  the  relative humidity is allowed to be larger at lower temperatures,such as  90%at+20°C,which should be taken into account due to changes  in temperature may occasionally produce condensation;
◇The tilt of the vertical plane when the device is installed does not exceed 5°,and the whole group of cabinets is relatively flat (in line with GBJ232-82 standard);
◇The device should  be  installed  in a  place where there  is  no severe vibration and impact and not enough to cause the electrical components to be corroded;
◇When the user has special requirements,it can be negotiated with the manufacturer.
