Analysis of GCS Low Voltage Drainage Switchgear
The device is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other low-voltage distribution systems. In large power plants, petrochemical systems and other places with high automation and high requirements for computer interface, as a low-voltage complete set of distribution equipment used for three-phase AC frequency of 50 (60) Hz, rated working voltage of 380 V (400), (600), rated current of 4000A and below, distribution in power supply system, centralized control of motor, reactive power compensation.
Characteristics of GCS Low Voltage Pumping Switchgear Device:
Increase the heat capacity of the adapter, greatly reduce the additional temperature rise caused by the temperature rise of the adapter to the connector, cable head and spacer. The separation between functional units and isolation units is clear and reliable, and the failure of one unit does not affect the work of other units, so that the fault is limited to a minimum range.
The East and heat stability of the bus parallel arrangement device is good, and it can withstand the impact of 80/176KA short circuit current. The number of circuits in MCC cabinet is up to 22 circuits, which fully considers the needs of automatic electric door (machine) groups in large single capacity power plants, petrochemical systems and other industries. The connection between the device and the external cable is completed in the cable compartment. The cable can go up and down, and the zero sequence current transformer is installed in the cable compartment to facilitate installation and maintenance. The same power distribution system can limit short-circuit current by matching current-limiting reactor, stabilize bus voltage at a certain value, and partly reduce the requirement for short-circuit strength of components.
The drawer unit has a sufficient number of secondary connectors (32 pairs of 1 unit and above, 20 pairs of 1/2 units), which can meet the requirements of the number of computer interface and automatic circuit docking points.
