Main Application

GCS device is suitable for power distribution system in power plant, petroleum, chemical, metallurgy textile, high-rise building and other industries. It's three phase AC 50(60)Hz low-voltage complete set of distribution device with rated operating voltage of 380V (400V),(600V)and rated current

This series low voltage withdrawable switchgear is a combined cabinet type assembled by factory (FBA) with standard modules.

This series low voltage withdrawable switchgear is suitable for power plant, substation, petrochemical industry, metallurgy, steel rolling, transportation, energy, light industry, textile and other industrial enterprises and residential area, high-rise buildings and other places, and it's used for electric energy conversion, distribution and control of electric power system of AC 50-60Hz power system with rated operating voltage 660V and below.

The device conforms to GB 7251.1 Low-voltage switchgear and control gear assemblies-Part 1: Type-tested and partially type-tested assemblies and national professional standards and IEC 439-1 international standard.

Performance index

The design of the device meets the following standards:

● IEC439-1 Low-voltage switchgear and control gear assemblies-Part 1: Type-tested and partially type-tested assemblies

● GB 7251 Low-voltage switchgear and control gear assemblies-Part 5 Assmebly for power distribution in public networks

● ZBK 36001 low-voltage withdrawable switchgear

Basic technical parameter

Device feature

● lmproving the heat capacity of the adapter,and greatly reduce the additional temperature rise caused by the temperature rise of the adapter to the connectors,cable logs and spacers.

●The separation between functional units and compartments is clear and reliable,and the failure of one unit will not affect the work of other units so as to minimize the failure.

● The horizontal arrangement of the bus bar makes the device have good dynamic and thermal stability,and can withstand the impact of 80/176kA short-circuit current.

● The number of circuits in a single MCC switchgear is as many as 22,which fully considers the needs of large single-unit power generation,petrochemical systems and other industries for automated motor groups.

● The connection between the device and the external cable is completed in the cable compartment,and the cables can be entered and exited up and down.The current transformer is installed in the cable compartment to facilitate installation and maintenance.

● The same power distribution system can limit the short-circuit current through the matching of current-limiting reactors,stabilize the bus voltage at a certain value,and partially reduce the short-circuit strength requirements of the components.

●The drawer unit has a sufficient number of secondary connectors (32 pairs for 1 unit and above,20 pairs for 1/2 unit),which can meet the requirements of the number of computer interfaces and automatic control circuits.

Auxiliary circuit

The design of the auxiliary circuit diagram conforms to the "Technical Regulations for the Design of Auxiliary Power for Thermal Power Plants"and other relevant design technical regulations.It is applicable to the low-voltage power system of power plants and substations and the low-voltage power distribution systems in factories and mining enterprises and high-rise buildings.. The auxiliary circuit solution is designed according to the main circuit solutions,which features the functional units of the power supply cable,the feeder (PC) and the motor feeder (MCC) for operation control.
