ABB UniPack-S Steel Compact Substation

LVS 2: Frame structure (1.5mm galvanized steel), with DIN rails on the top for measuring equipment, cover plate RAL 7035. Similar to LVS 1 but supports higher current and advanced incoming line protection.

LVS 3: Independent (2mm galvanized steel frame), with the incoming line located above the busbar, can be configured with ACB (Emax2) up to 3150A. The busbar length is 12/16/20 modules, and the rated current is up to 5000A (DIN busbar). There is space at the top to install incoming circuit breakers, streetlight equipment, measuring equipment, etc.

All LVS comply with IEC 61439-1, and the system grounding can be TN-C (4-wire, PEN grounded or insulated) or TN-S (5-wire, N and PE separated).

6.5 Selection of Switchgear

Tmax molded case circuit breaker: up to 1600A, fixed, plug-in or withdrawable versions, high breaking capacity, remote control and bus communication.

Emax 2 air circuit breaker: up to 6300A, fixed or withdrawable, with a breaking capacity of 42-200kA, supporting Modbus, Profibus, DeviceNet, Modbus TCP, Profinet, EtherNet/IP, and IEC 61850 communication.

OT series isolating switch: compact design, AC-23A full current rating, up to 690V/1000V, fast switching mechanism, no need for capacity reduction.

InLine vertical fuse switch: used for DIN NH fuses, 160-1250A, maintenance free, supports electronic fuse monitoring (EFM) and remote indication, with simple selective calculation (upper and lower current ratio of 1.6:1).

Kabeldon fuse system: Insulated busbar system (400-2500A), including connectors, isolating switches, switches, fuse switches, MCCBs, etc., with short assembly time and compact design.

Smart grid compatibility

ABB has defined four levels of CSS automation solutions:

Level 1: Basic monitoring, including overall CSS monitoring, low-voltage side current/voltage/energy measurement.

Level 2: Add control of medium and low voltage primary equipment on the basis of Level 1.

Level 3: Add precise current, voltage, and energy measurement on the medium voltage side based on Level 2.

Level 4: Adding the protection function of incoming and outgoing circuit breakers on the basis of Level 3 is the most complete technical solution.

The benefits of automation include improving power supply quality, reducing the frequency and duration of power outages, enhancing voltage quality, improving operational efficiency and network stability, improving operation and maintenance tools, and reducing travel to difficult to reach locations.

Environmental Protection and Recycling

The UniPack-S series is produced according to ABB's strict quality and environmental procedures and is certified by ISO 9001 and ISO 14001. ABB is committed to developing and supplying products that have minimal environmental impact, are safe to use, recyclable, reusable, or disposed of safely. The research and development goal is to generate sustainable technologies, systems, and products.
