I. Overview
GCS withdrawable switchgear is suitable for power generation and supply systems with power levels of 3-phase AC 50Hz, rated working voltage 400V(690V) and rated current up to 4000A, satisfying power distribution, motor concentrated control and capacitance compensation. It is widely applied in places like power plants, petroleum, metallurgy, textile and tall buildings, conforming to relevant standards such as IEC60439-1, GB7251.1 and JB/T9661.
II. Main characteristics
1. The frame is adopted with KS profiles. The mounting holes in Φ9.2mm with module E=20mm and 100mm on the main framework enables its assembly flexible and convenient;
2. The switchgear is divided into function unit compartment, busbar compartment and cable compartment with each compartment isolated and function relatively independent;
3. The horizontal busbar is placed flat at the back as to strengthen its capability against electromotive power, which is a basic measure to make the main circuit have strong short circuit capability;
4. The design of cable compartment facilitates easy access of cable;
5. The module of drawer height is 160mm, and the drawer changes only in height, not in width and depth. The drawers of same function units have great interchangeability. The rated current of unit loop is up to 400A;
6. The drawer panel is marked with obvious signs for positions as breaking, making, testing and drawing out. The drawer unit is provided with mechanical interlock device. Usually, drawer units are the main options, but they can be mounted together with fixed units in one cubicle for random use;
7. The degree of protection of the enclosure is IP30-IP40 or determined upon request.
