Switchgear & Control Gear Assembly
What is Switchgear Assembly ?
A low-voltage switchgear and control gear assembly (ASSEMBLY) is a combination of low-voltage switching devices together with associated equipment (controlling, measuring, signaling, protective, regulating etc.) complete with all the internal supporting structures, enclosures, conductors, mechanical and electrical interconnections and accessories.
Where are these assemblies used?
Switchgear and control panels are found in Power Generating Stations, Transformer stations, Distribution substations, Commercial and Institutional buildings, Industrial plants and Factories, Oil & Gas production facilities, Oil Refineries, Petrochemical Plants, Paper mills, Metal smelters and any other place where electric energy is utilized or electric power is distributed to any number of indoor and outdoor locations.
There are a few common types of assemblies that cover almost any application. A broad classification according to the location of the Switch Gear Assemblies is whether the gear is installed indoor or outdoor. A further classification for the indoor gear is standard ventilated.
Devices in Switch gear the Switch gear can contain as switching/interrupting device(s):
Enclosures, Busbars, Supports, Air Circuit Breakers (ACB),Moulded Case Circuit Breakers (MCCB),Miniature Circuit Breakers (MCB), Residual Current Devices (RCD), Surge Protective Devices (SPD), Switches, Isolator, Metering devices, Instrument Transformers, Protective Relays, Auxiliary devices, limit switches, latching devices, Switch/Fuse combination, a contactor/fuse combination (for motor switching), for low voltage (L.V.) assemblies: a switch or breaker in series with a contactor (for motor switching). Barriers and shutters Certain configurations come only as non draw out construction, others as draw out. If special requirements for the gear are needed, the special property can be used as criteria for defining the gear, for example, if dust tight enclosure is required due to the presence of dust (fine or course) in the atmosphere this gear is designated as dust tight.
For switchgear assemblies, as heat is generated from the high current flowing, a dust tight enclosure is almost impossible thus a dust proof one is used, instead. The major standards that govern the design, manufacture and testing of these assemblies are: IEC, CSA, ANSI, IEC, EEMAC, NEMA.
Switchgear assemblies and motor control centres (starters) line-ups can be classified according to their voltage classes. The L.V. equipment is rated in the range of 120/230V single or three phases to 750V AC. The medium voltage ones are 2400/4160V to 44KV.
The enclosures for all low voltage construction are metal enclosed. Some constructions include partitions and barriers to give a safer operation over and above the standard construction.
For medium voltage switchgear both construction types, metal clad and metal enclosed, are common. In this section, the major components of the switchgear assemblies, motor starters and associated ancillaries will be given.
