1 Overview

GCS type low-voltage switchgear (hereinafter referred to as the two foot joint device) designed according to industry authorities, the majority of users and the design requirements of power unit is developed with the situation of China, with high technical performance, can adapt to the development of power market and the need to introduce low voltage switchgear products competition. The device was approved in 1996 by two co chairs in Shanghai in the year of July. By the manufacturing units and the use of electricity sector attention and affirmation.

Notice of the Ministry of electric power industry and the Ministry of machinery industry on the issue of the application of GCS type low voltage draw out switchgear on the safety of [1997]01 and [1997]01. The day before, GCS type low-voltage switchgear has been widely used in electric power users.

2 scope and use

The device is suitable for power plant, petroleum, chemical industry, metallurgy, textile, high-rise building and other industries. Automation in large power plant, petrochemical system and computer is connected with a high degree of portal sites, as the three-phase AC frequency of 50 (60) Hz, rated voltage of 380V (400), (660), the rated current is 4000A and below the power generating and supply system, motor centralized control, reactive power compensation for the use of low voltage power distribution equipment.
