Specifications

GCS type low-voltage switchgear (hereinafter referred to as device) is the ministry of electric power industry, machinery industry to promote the technological progress of low-voltage distribution industry in China, accelerate the upgrading of low-voltage distribution of switch equipment, protect and promote the national industry for the purpose, in 1995 entrust the source electric co., LTD organized two GCS type low-voltage switchgear joint design group (hereinafter referred to as the two joint group) complete design and development, at present in the country has been preliminary affirmation and selection, to facilitate the design, use unit application, write this specification.

The device is suitable for power conversion, distribution and control of power, distribution and motor control center, capacitor compensation, including power plant, substation, petrochemical department, factory and mining enterprises, and high-rise buildings.

In the power plant with large single capacity, the low-voltage power control center and motor control center can meet the special needs of the interface with the computer.

Device is according to the electric power competent superior, the requirements of the general power users and design department, to meet the fear of the development of electric power market for capacity, computer interface, power centralized control, convenient installation and maintenance, shorten the accident processing time, based on the principle of safety, economic, reasonable, reliable design of new low voltage draw switch cabinet, product with points, broken, high ability, good thermal stability, flexible electrical scheme, convenient combination, series practicability, novel structure, protection level, can be used as a low-pressure draw switch cabinet replacement products.

The surrounding air temperature shall not be higher than + 40℃, not less than-5℃, and the average temperature within 24 hours shall not be higher than + 35℃. When exceeding, the operation shall be reduced according to the actual situation. For indoor use, the altitude of the use site shall not exceed 2,000 m.

The relative humidity of the surrounding air should not exceed 50% at the highest temperature is + 40℃, and a large relative humidity is allowed at the lower temperature, such as 90% at + 20℃. It should be considered the effect of accidental condensation due to the temperature change.
