Summary
GCK series motor control center is mainly composed of some combined motor control units and other functional units. These units are overlapped above and below the way installed in the closed gold It belongs to cabinet. Each cabinet body is connected together with a horizontal bus set above the cabinet body, and the functional units of the same cabinet body are connected in parallel on the vertical bus. The cabinet is divided into four isolated areas: horizontal bus area, vertical bus area, cable area and equipment installation area. The functional units are respectively installed in their own rooms. When any functional unit has an accident, it will not affect other units to prevent the accident from expanding.
This product conforms to zbk3600.1-89 "low voltage drawer type complete switchgear" standard. The product adopts lp40 protection grade specified by lec114, when all doors and guard boards are closed, or When opening and when the functional unit is in the moving position, it can reach the corresponding protection level, so as to ensure personal safety.
The product is equipped with perfect and reliable grounding system and protection circuit. All functional units can break the short-circuit current according to the specified performance requirements. The incoming line unit has three section protection characteristics. because This can ensure the reliability of power supply and the safety of equipment and system.
All functional units can be connected with PC line board (programmable controller) or microprocessor through interface devices. As the execution unit of automatic control system, they can also be provided according to the needs of users Function unit and function combination of other contents, the product is applicable to the circuit with 380V AC and 50Hz frequency.
GCK low voltage draw out switch cabinet is composed of power distribution center (PC) cabinet and electric control center (MMCC). It is suitable for power users such as power plants, substations, industrial and mining enterprises as AC In the distribution system with 50Hz, maximum working voltage a660v and maximum working current 3150A, it is used for power distribution, motor control and lighting distribution equipment.
This series of products have high breaking capacity, good dynamic and thermal stability, advanced and reasonable structure, practical electrical scheme, series, strong universality, any combination of various scheme units, one set The cabinet has many circuits, saving floor space, beautiful appearance, high protection level, safety and reliability, convenient maintenance and other advantages.
This product conforms to the standard of L ec439 n emal cs2-322, the national standard of low voltage switchgear package (GB725 1-2006) and the low voltage withdrawable switchgear package (ZB k3600 1-89) Equipment.
