Fluair 100/200: 3 to 17.5 kV The Fluair range: a reliable installation
The Fluair range The Fluair range comprises a series of homogeneous, compatible, factory-built panels, designed for use in MV installations rated from 3 to 17.5 kV. Since the switchgear units are of a withdrawable design and can be used with a remote control system, the range is ideally suited for all types of applications and installations which call for: s continuity of service; s easy commissioning; s quick assembly; s user and system safety; s flexibility in operation; s easy extension; s low maintenance costs. Inside the range, the Fluair 100/200 is used to build single or double busbar 3 to 17.5 kV distribution switchboards encountered in: s electrical power-generating stations (feeds to station auxiliaries), s primary substations in the public distribution sector, s in MV process installations, s in distribution and final distribution substations in the industrial or tertiary sector.
Metal-clad substations The Fluair panels are made up of factory-built metal enclosures of the metal-clad type in accordance with IEC international standards. These panels comprise 4 fully self-contained compartments: s a switchgear compartment, s a cable connection compartment, s a busbar compartment, s a control gear compartment. All the metal frames are permanently connected together electrically.

Degree of protection
Interlocks Operating safety is enhanced by a series of interlocks designed to: s prevent incorrect operation, s prevent direct access to current-carrying parts, s restrict access to the network control equipment.
Withdrawable circuit-breaker units The Fluair range of panels are fitted with SF6 circuit-breaker units.
IP 3X or IP 5X to IEC 529 (a higher level of protection can be provided on request).
Surface treatment All the metal surfaces in the panels are treated against corrosion: s the outside panels are protected by galvanisation and with an epoxy polyester coating standard colour RAL 1011 or RAL 7030, and have been put through the surface tests laid down in standards IEC 68-2-11. s the internal partitions are protected against corrosion by galvanisation, with chrome passivation.
withdrawable
The circuit-breaker and its operating mechanism, mounted on a slide-out truck make for fully-visible isolation and simple, 100% interchangeability. This technology provides the users with the best guarantee of continuity of service for their installations.
Rigorous testing The Fluair panels have successfully undergone the type approval tests set down in the IEC international standards, including: s dielectric tests, s temperature-rise tests, s mechanical endurance tests, s short time withstand current and peak withstand current tests. In addition to these standardised tests, the requirements for other types of installation can also be met. For example: s resistance to humid conditions, s resistance to internal arcing (in accrodance to IEC international standards).

Fluair 100/200: 3 to 17.5 kV Withdrawable circuit-breakers ≤ 17.5 kV
SF6, the switchgear gas Fluair circuit-breakers use sulphur hexafluoride (SF6) for isolation and breaking. The active parts are housed in an insulating enclosure of the sealed pressure system type, in compliance with IEC 56. The devices used to equip the Fluair range of functional units have outstanding features: long service life, maintenance-free active parts, s high electrical endurance, s very low switching surges, s operating safety, s insensitivity to the environment, s breaking capacity and dielectric strength maintained at atmospheric pressure, s low filling pressure. s s
Circuit-breaker range Circuit-breaker ranges are used in 7.2 to 17.5 kV cubicles. Breaker operation is based on SF6 technology. The circuit-breaker is of the sealed pressure system type. The gas-tight enclosure is filled with SF6 at a low gauge pressure of 0.15 MPa (1.5 bar). A pressure switch with a NO contact for continuous monitoring of the SF6. Low pressure filling guarantees reliable gas-tightness. Circuit-breaker ranges are actuated by RI type spring stored energy operating mechanisms.
Self-expansion interrupting principle for LF circuitbreaker range The operating principle combines the rotating arc technique with the effect of thermal expansion. The contacts are housed inside a chamber which provides the volume for expansion.
Circuit-breaker closed (fig. 1) Main contacts open (fig. 2) The main contacts open and the current is transferred to the arcing contacts.
Arcing period (fig. 3) The arcing contacts separate. The arc is cooled by rotation, caused by a magnetic field created by the coil when the current is low. The over-pressure of thermal origin produced by the arc in the expansion chamber extinguishes the arc by forcing it into the hollow contact.
