GCS low voltage distribution cabinet
GCS low-voltage power distribution cabinet (hereinafter referred to as the device) is the Ministry of Power Industry and Machinery Industry to promote the technological progress of China's low-voltage power distribution industry to accelerate the upgrading and replacement of low-voltage power distribution switchgear and the promotion of China's national industry. In 1995, we entrusted Senyuan Electric Co., Ltd. to organize two GCS-type low-voltage withdrawable switchgear joint design groups (hereinafter referred to as the two joint groups) to complete the design and development. At present, it has been initially confirmed and selected nationwide. The majority of the design, make the unit application. Write this manual.
Scope of application
The device is suitable for power conversion, distribution and control of power plants, substations, petrochemical departments, factories and mines, high-rise buildings and other low-voltage power distribution systems, power distribution and motor control centers, capacitor compensation, etc.
In the large single-capacity power plants, large-scale petrochemical and other industries, such as low-voltage power control centers and motor control centers, it can meet the special needs of computer interfaces.
The device is based on the requirements of the supervisors of the Ministry of Power, the majority of power users and the design department to meet the special needs of the growing power market for capacity expansion and computer interface.
The device is based on the requirements of the power department supervisors and the design department of the Ministry of Power to meet the needs of the evolving power market. The computer interface, centralized power control, convenient installation and maintenance, shortened accident handling time, etc.. Safe, economical, The new low-voltage withdrawable switchgear designed by reasonable and reliable principle has the characteristics of high breaking, high connecting capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, strong seriality and practicality, novel structure and high protection level. Used as a replacement for low-voltage withdrawable switchgear.
The device complies with EC439-1 "Low-voltage switchgear and control equipment", GB7251 "Low-voltage switchgear" and other standards.
Model and meaning
Conditions of Use
1. The ambient air temperature is not higher than +40C. Not lower than -5 °C. The average temperature within 24 hours shall not be higher than 35 °C. When it exceeds, it shall be derated according to the actual situation.
2. The altitude of the place of use in the household shall not exceed 2000m.
3. The relative temperature of the surrounding air does not exceed 50% at the highest temperature of +40 ° C. At higher temperatures, a larger relative humidity is allowed, such as 90% at +20 C. It should be considered that the temperature may change by chance. The effect of condensation.
4. When the device is installed, the inclination of the vertical surface shall not exceed 5% and the whole set of cabinets shall be relatively flat in accordance with GBJ23282 standard).
5. The device should be installed in a location where there is no violent vibration and shock and insufficient electrical corrosion of the electrical components.
6. When the user has special requirements, it can be resolved in consultation with the manufacturer.
