A consistent design of offers from Medium Voltage to Ultra terminal

All Merlin Gerin offers are designed according to electrical, mechanical and communication consistency rules.The products express this consistency by their overall design and shared ergonomics.

Electrical consistency:

Each product complies with or enhances system performance at co-ordination level: breaking capacity, Isc, temperature rise, etc. for more safety, continuity of supply (discrimination) or economic optimisation (cascading).The leading edge technologies employed in Merlin Gerin’s Guiding System ensure high performance levels in discrimination and cascading of protection devices, electrodynamic withstand of switches and current distributors, heat loss of devices, distribution blocks and enclosures.Likewise, inter-product ElectroMagnetic Compatibilty (EMC) is guaranteed.

Discrimination guarantees co-ordination between the operating characteristics of serial-connected circuit-breakers. Should a fault occurs downstream, only the circuit-breaker placed immediately upstream from the fault will trip.

Mechanical consistency:

Each product adopts dimensional standards simplifying and optimising its use within the system.It shares the same accessories and auxiliaries and complies with global ergonomic choices (utilisation mode, operating mode, setting and configuration devices, tools, etc.) making its installation and operation within the system a simpler process.

Prefabricated and tested solutions, upstream and downstream from the device complying with the IEC 60439-1 switchboard standard.

Communication consistency:

Each product complies with global choices in terms of communication protocols (Modbus, Ethernet, etc.) for simplified integration in the management, supervision and monitoring systems.

Thanks to the use of standard Web technologies, you can offer your customers intelligent Merlin Gerin switchboards allowing easy access to information: follow-up of currents, voltages, powers, consumption history, etc.

F400 internal arcing (in conformance withIEC 62271-200)

Annex A of IEC 62271-200 defines the “method for testing the metal-enclosed switchgear under conditions of arcing due to an internal fault”.The F400 cubicle conforms to this standard and has successfully passed all the type tests specified by this standard. The F400 cubicle is therefore designed to provide the highest possible degree of protection for operators in the vicinity of the equipment in the event of an internal fault.

The F400 internal arc protection is AFLR type (all four sides of the cubicle are protected) in order to protect operators when they go behind the cubicle. The F400 switchboard is installed in a room with a minimum height of 4 m.F400 is designed to eliminate the effects of internal arcing safely, by:b locating metal flaps above the enclosure to limit overpressure in the compartments in the event of an internal fault,b using nonflammable materials for the cubicle,v F400 can be fitted with an optional system to detect internal arcing and disconnect the power supply in order to limit the duration of the fault current to less than 140 ms.

Switchboard operationsThe switchboards are installed, operated and maintained from the front panel. Certain installation and maintenance operations are performed from the rear of the cubicle:b installation of medium voltage cables,b operation of voltage transformers (PT).

F400 range Personal protection (continued) 0

Dependable mechanical control devicesThe switchboards are operated from the front panel. The operator is guided by means of pictograms on each front panel, which make it very easy to understand the sequence of operations and the status of the devices.Interlocks and padlocks prevent operator error. The operator is protected by several additional security levels:b Racking in or out is only permitted with the door closed.b The comprehensive set of mechanical and electrical interlocks prevent operator error. Keylocks or padlocks can be added, depending on the specific operating procedures required.Each selector can be fitted with one to three padlocks.b All operations are performed from the front panel.b The power-on indicator is located on the front panel of the functional unit, in the immediate vicinity of the earthing switch control.

Optionsb Circuit breaker disabling during extraction. This function enables the circuit breaker control springs to be disabled during the extraction process. b Rack-in inhibition. This function prevents the withdrawable part from being racked in.

Instrument transformers 0

Conventional current transformers are used to provide power to measuring, metering or monitoring devices. They measure primary currents from 50 A to 2500 A.

Schneider Electric has drawn up a list of preferred current transformers which are appropriate for use with digital protection devices to make it easier to determine accuracy characteristics.

The live parts of the dry-insulated current transformers are integrated into a resin enclosure. These compact transformers have excellent electrical and mechanical characteristics and are fully protected against fire hazards.

Conventional current transformers provide power to the “current” circuits of the measuring instruments and/or protection devices.

Functional current transformersF400 cubicles are fitted with functional current transformers.These transformers are integrated into the power bushings on which the fixed rack-in contacts are mounted.The current transformers have one, two or three 1 or 5 A secondary windings (1). The transformation ratios can be changed in the LV control cabinet.

4 SF circuit breakers work on the basis of the “puffer” type principle in SF6, which is used as a breaking and insulating gas. Each of the three poles is independent and has a sealed pressure system type insulating enclosure in compliance with IEC 62271-1. Each pole forms a gas-tight unit filled with SF6 at a low relative pressure of 0.25 to 0.35 MPa (2.5 to 3.5 bar) depending on the performance level required.An optional pressure switch on each pole operates an alarm in the event of a pressure drop.SF6 circuit breakers are actuated by a GMH energy accumulation control.

3 The sulphur hexafluoride (SF6) provides the insulation and breaking functions in SF circuit breakers.The live parts are housed in an insulating enclosure which is sealed for life, as specified in IEC 62271-100.

The switchgear used in the F400 cubicles therefore has the following characteristics:b long service life,b maintenance-free live parts,b high electrical endurance,b very low overvoltage,b dependability,b environmental insensitivity,b possibility of continuous monitoring of the status of the circuit breaker.

7 The main contacts and arcing contacts are initially closed (fig. 1).

Pre-compression (fig. 2)When the contacts begin to open, the piston compresses the SF6 gas slightly in the compression chamber.

Arcing period (fig. 3)The arc appears between the arcing contacts. The piston continues its movement. A small quantity of gas, directed by the insulating nozzle, is injected across the arc.For low current breaking, the arc is cooled by forced convection.However, for high current breaking, thermal expansion causes the hot gases to move towards the cooler parts of the unit.The distance between the two arcing contacts then becomes sufficient for the current to be broken permanently when it first reaches the zero point, due to the dielectric properties of the SF6.

Sweeping overtravel (fig. 4)The moving parts finish their movement and the injection of cold gas continues until the contacts are completely open.

SF circuit breakers are actuated by the GMH operating mechanism which ensures that the closing and opening speed of the breaking device is not operator-dependent.

The circuit breakers are fitted with a GMH electrical operating mechanism. They are used for remote operation and to ensure a fast resetting cycle.

The GMH electrical operating mechanism includes: b an energy accumulation mechanism that stores, in the springs, the energy required to close and open the breaker,b a manual lever-operated resetting device,b an electrical motor-operated resetting device that automatically resets the control as soon as the breaker closes (time y 15 s),b a mechanical opening and closing device operated by two pushbuttons on the front panel,b an electrical closing device including: v a closing release for remote control with an anti-pumping relay,b an electrical opening device including one or more opening releases that may be one of the following types:v power on,v undervoltage,v a low consumption mitop(1),b an operation counter,b an optional reset control indication contact,b a resetting limit switch contact,b a black/white mechanical “open-closed” position indicator,b a multi-pin connector to isolate auxiliary circuits in the “racked out” position.

Auxiliary contactsThe GMH operating mechanism is fitted with a block of 14 auxiliary contacts including:b 1 changeover contact for the electrical control,b 1 changeover contact for indication,b 1 contact for the power-on release. The number of available contacts depends on the composition of the control and on the options selected (see table below).

Installation F400 connection

Switchgear resistance to ageing in a substation depends on 3 key factorsbbbb Correctly made connectionsNew cold-connecting technologies facilitate installation and improve durability over time. They are designed for use in polluted environments with harsh weather conditions.bbbb Impact of relative humidityIt is essential to install a heating element in climates with high relative humidity and wide temperature differentials.bbbb Ventilation controlThe dimensions of the air vents must be appropriate for the energy dissipated in the substation. They must sweep only the transformer environment.

The end-pieces are cold-connectableSchneider Electric’s experience has led it to favor this technology wherever possible for optimum durability over time. The maximum permissible cable cross-sections for standard assembly are: bbbb 1200 mm2 for incomer or feeder cubicles with single-pole cables,bbbb 400 mm2 for incomer or feeder cubicles with three-pole cables,bbbb the diameter of the cables must be yyyy 95 mm2.Access to the compartment is only possible when the earthing switch is closed.

Dry single-pole cable

Dry three-pole cable

Connection possibilities using dry cables

(1) Possibility of installing AOPC LV toroid type current transformers.(2) Possibility of installing ARL4 LV toroid type current transformers.(3) Possibility of installing ARL5 LV toroid type current transformers.
