GCK type complete set switch device
1. General
1.1 Brief introduction
GCK type complete set switch device is designed according to safe, economic, proper, reliable principles, to meet the requirements of various electric users, to meet the requirements of capacity increase, computer port, power center control, installation and maintenance, decrease fault remedy time. With its good breaking capacity, flexible electric scheme and combination, strong practicability, novel structure, high protection grade and other features it can be the replacement product of old low voltage complete set switch cabinet devices.
1.2 Application range
GCK type complete set switch device is suitable for power distribution system and substation of power plant, petrochemical, chemical, textile and other industries. It is used in large power plant, petrochemical and other places with high degree of automation and computer port as 3 phase AC low voltage complete set power distribution devices with 50(60) Hz, rated voltage 380V(400)(660), rated current less than 4000A for power distribution, motor center control and reactive power compensation of power distribution system.
1.3 Technical features
1.3.1 GCK system motor control center consists of a few combination type motor control units and other functional units. These units are installed top and bottom overlap in metal enclosed cabinet. Cabinets are connected by horizontal bus bar installed at upper compartments. Functional units in same cabinet are parallel connected to vertical bus bar. The cabinet has horizontal bus bar compartment, vertical bus bar compartment, cable compartment, device installation compartment four isolated compartments. The functional units are installed in respective compartment. In case one functional unit breaks down, other units will not be influenced to prevent fault enlarge.
1.3.2 GCK product conforms to ZBK36001-89 standard. It conforms to IP40 protection grade according to IEC114. When all doors and guard boards are open, or the doors are open and functional units are withdrew out, it can reach the corresponding protection grade to ensure the safety of operators.
1.3.3 The product is equipped with perfect grounding system and protection circuit. All functional units can open the short-circuit current according to the requirements. The incoming unit has three section protection feature. It can ensure the reliability of power supply and safety of devices and system.
1.3.4 All functional units can be connected to PC board (programmable controller) or micro processor via interface module as execution units of automatic control system according to the requirements of users. It is suitable for AC 380V, 50 Hz frequency circuit.
