The GCS type low-voltage withdrawable switchgear (hereinafter referred to as the device) was designed and developed by a joint design team in accordance with the requirements of the industry authorities, the majority of power users, and design units. It is a low-voltage withdrawable switchgear that conforms to the national conditions, has high technical performance indicators, can meet the needs of the power market development, and can compete with the existing imported products. Currently, this device has been widely adopted by power users. The device is applicable to the power distribution systems in industries such as power plants, petroleum, chemical industry, metallurgy, textiles, and high-rise buildings. In places with high automation requirements and computer interfaces in large power plants and petrochemical systems, it is used as a low-voltage complete distribution device for power supply, motor centralized control, reactive power compensation in the power distribution systems with a three-phase AC frequency of 50 (60) Hz, a rated working voltage of 380 (400) V (660) V, and a rated current of 5000 A or less. The basic structure of the device is shown in Figure 1. The design of the device complies with the following standards: IEC 439-1 "Low-voltage complete switch and control equipment" and GB 7251 "Low-voltage complete switchgear".
