Overview

GCS type low-voltage extraction switchgear is suitable for power plant, petroleum, chemical, metallurgy, textile, high-rise building and other industries.

In large power plants, petrochemical system, such as high degree of automation, and computer interface, as the frequency of the three-phase ac 50 Hz (60), rated working voltage of 400 v, 400 v, rated current is 5000 a and below the hair, power supply system of power distribution, centralized control of the motor, reactive power compensation using low-voltage power distribution equipment.

The device is designed to meet the following standards: iec 439-1 "low-voltage switchgear and control equipment" GB7251 "low-voltage switchgear"

Types of meaning

Normal use environment
◆Ambient air temperature is not higher than + 40 ℃, no less than 5 ℃, the average temperature in 24 hours shall not be higher than + 35 ℃.

When exceeding, it is necessary to reduce the capacity according to the actual situation;

◆The height of the site shall not exceed 2000m;
◆Ambient air relative humidity when the highest temperature is + 40 ℃ not more than 50%, at low temperature are allowed a larger relative humidity, such as + at 20 ℃ at 90%, should be considered due to the change in temperature may accidentally condensation effect;
◆Device installed with the inclination of the vertical plane was less than 5 °, and the whole tank column relatively flat (GBJ232-82 standard);
◆The device shall be installed in a place where there is no shock and shock and not enough to cause the electrical components to be not corroded.
◆When the user has special request, he can negotiate with the manufacturer
