GCK Low-voltage Withdrawable Switchgear
The GCK series switchgear consists of a power distribution center (PC) cabinet and a motor control center (MCC) cabinet. Applicable to power users such as power plants, substations, industrial and mining enterprises, etc. as a power distribution system with 50 Hz AC, maximum working voltage to 660V, and maximum working current to 3150A, as power conversion for power distribution, motor control and lighting. For distribution control purposes. The product has high breaking capacity, good dynamic thermal stability, advanced and reasonable structure, practical and practical electrical scheme, strong series and versatility, and any combination of various scheme units. The cabinets contain more circuits and save land. The area, the appearance is beautiful, the protection level is high, the safety is reliable, and the maintenance is convenient.
Product model and its meaning
Cabinet
b. Internal structural parts are galvanized.
a. The molding size of the parts, the opening size, and the device spacing are modularized. (modulus E = 20mm, the same below).
d. The cabinet is divided into three separate sections of busbar, functional unit and cable to prevent accident spread and easy to charge the functional unit (drawer part)
c. Each MCC cabinet can be installed with up to 9 one-unit drawers or 18 one-unit drawers.
f. The functional unit compartments are separated by a metal partition.
1. The basic skeleton of the switchgear is a combined assembly structure. The whole structure of the cabinet frame is made by self-tapping screws, and the door, partition, sealing plate, bracket and busbar, drawer and electrical components are complete. Switch cabinet. Since the original GCKI skeleton adopts the GF28 profile, the profile steel plate is thinner, and in addition, when the profile is galvanized, a part of the interior has a dead angle, so that the service life of the cabinet is greatly shortened. At the same time, factors such as the standardization of its overall structure are taken into consideration. Our company boldly improved. Type C special profiles are used. It is made of 25mm modulus and 2mm thick steel plate. It is reinforced with self-tapping screws with strong rigidity during assembly, which makes the combination more flexible and convenient, and the service life is longer.
3. According to the characteristics of the switchgear, it can be divided into power receiving cabinet, PC cabinet (power center), MCC cabinet (motor control center) and capacitor compensation cabinet.
6. In order to ensure the personal safety of the operating procedures and maintenance personnel, a mechanical interlocking mechanism is arranged in the switch cabinet, and a mechanical interlocking mechanism is arranged in the drawer unit and the door and the main switch. Make it use more
9. The ventilation system is provided at the top of the switchgear and the upper and lower ventilating doors without reducing the degree of protection.
