Opening

Opening When an electrical or manual opening order is given, the energy accumulatedin the opening spring (7) is released.

The insulating tie--rod (8), directly activated by the opening spring (7), trans-mits the movement to the transfer mechanism (9) inside the housing whichcauses the contacts to separate simultaneously in both chambers.

Operation The table below gives the stages of opening :

Stage DescriptionStart of opening When the moving contact (4) separates from the main

contacts (3), the current is switched onto the arc con-tacts (10). The compression of the (Vp) volume cau-ses the first rise of pressure.

103 4 Vp

Thermal effect When the contacts (10) separate, the arc appears andits energy causes the pressure to rise in the thermalexpansion volume (Vt), closed by the fixed contact rod(11) and the insulating nozzle (12).

12 10 Vt11

Interrupting andassistanceat opening

When the rod (11) comes out of the nozzle (12), thethermal overpressure in the volume (Vt) is releasedcausing an energy blast to occur, just before the cur-rent zero passage, ensuring final quenching of the arc.The (Vp) volume pressure decreases to the ambientpressure by means of the valve (13) to allow the endof the opening.

Opening, continued

Molecular sieve The arc has been extinguished.The SF6 molecules, separated by the arc, are re--formed instantaneously.Residual gases left over from the interruption operation are adsorbed by themolecular sieve situated at the base of the pole. A few powdery compoundsare deposited in the form of dust which is quite harmless for the circuit break-er.

Special caseof small currents

For small currents (example : operating no--load lines, transformers or ca-pacitor banks), the thermal energy of the arc is too low to provide enough ex-cess pressure.Consequently, the conventional autopneumatic effect developing in the vol-ume (Vp) is used mainly, to blast the arc.

Closing

Description When an electrical or manual closing order is given, the energy accumulatedin the closing spring (15) -- situated inside the operating device -- is released.This energy is transmitted directly to the pole operating shaft (16), to ensureclosing.The release of the energy stored up in the closing spring (15) causes displace-ment of the moving parts -- and so the closing of the interrupting chambers-- and also reloads the opening spring (7).

Gas pressure and density

Introduction The electrical characteristics of switchgear depend on the density of SF6 gasi.e. the mass of gas pumped into a compartment of a given volume.

Constanttemperature

At constant temperature, an increase of gas density results in a higher gaspressure against the walls of compartment.

Constant density At constant density, with an fixed compartment volume, the pressurechanges in the same way as the temperature. Since the gas density re-mains invariable owing to the fact that no modification occurs in the quanti-ty of gas or the volume of the relevant compartment, the electrical charac-teristics of the switchgear will remain unchanged.

Conclusion Since it is difficult to measure the gas density directly, it is essential toknow accurately its absolute pressure and temperature.


L20--001EN/063/6

09--2004E AREVA

Pressure measurement

Effective pressure ?Absolute pressure ?

Absolute pressure = effective pressure + atmospheric pressure

Pressure Description Diagram

Effective

The pressure of SF6 gas is mea-sured by of a standard pressuregaugewith adeformable diaphragmactuating an indicating pointer.One surface of the diaphragm is incontact with the SF6 gas, while theother is in contact with the atmo-sphere. The difference between thegas and the atmosphere is thusmeasured, taking atmosphericpressure as a reference. This is themeasurement of the effective pres-sure of the SF6 gas.

SF6

Atmospheric pressure

Standard pressure gauge

Absolute

If the deformable diaphragm, onesurface of which is in contact withthe SF6 gas, blocks a volumewherea vacuum has been developed, thepressure gaugemeasures thepres-sure difference between that of theSF6 gas and the vacuum. Since thelatter is zero, the pressure gaugemeasures the absolute pressure ofthe gas.The absolute pressure of the SF6gas, independent of atmosphericpressure, reflects the quantity ofgas introduced into the compart-ment and hence its density at thepresent temperature.This is measured by means of anabsolute pressure gauge which isless generally used and more deli-cate than a effective pressuregauge. This is the reason why a ef-fective pressure gauge is used, pro-vision being made for correctionsrequired by atmospheric pressurevariations resulting from atmo-spheric disturbances and differ-ences of elevation.

Measuring density

Pressure units D The international unit pressure is the Pascal (Pa).D The practical unit is the bar (14.503 p.s.i.)

1 bar = 1,000 hPa1 bar = 100 kPa10 bar = 1 MPa

D Standard atmospheric pressure is equal to 101.3 kPa at sea level and anair temperature of 20C (68F).

Measuring density When it is not possible to directly measure density, this may be checkedusing an industrial pressure gauge capable of measuring the effectivepressure.An effective pressure value corresponds to the rated density, determinedfor normal atmospheric pressure (101.3 kPa) and an ambient temperatureof 20C (68F).

For each pressure reading (filling, inspection of densimeter thresholds...), therated effective pressure should be corrected according to the ambient tem-perature and atmospheric pressure of the site at the time the reading is taken.See the module Calculation of the SF6 gas filling pressure to using thepressure gauge (tool).

The real pressure is therefore :

Preal = Prated effective in accordance with temperature + Pp*

* Pp : correction in accordance with atmospheric pressure.

Localization The densimeter is situated onto the bottom of the pole of the circuit--breaker,and joined to the gas volume of the circuit--breaker.

Working The densimeter is fitted with internal contacts. These contacts close succes-sively if the gass density diminishes and determine 2 distinct thresholds.These contacts are wired to the terminal block inside the cubicle and are usu-ally left at the users disposal for the following use :D Alarm pressure pae acts as a warning (topping up necessary).

D Minimum functional pressure for insulation pme must be used either tolock the circuit--breaker in position or to cause automatic opening. The optionis chosen by the client in keeping with operating requirements.

Introduction The storage procedures defined below are for storage times of less than 2years. For longer periods, special packagingmust bedesigned andappropri-ate procedures devised.

Short--term storage(6 months)

Theapparatusmust be stored in its transport packagingandplacedonbeamsin a flood--proof place.

Medium--term storage(less than 2 years)

The table below indicate how to stock the main components of the circuit---breaker for a medium--term storage :

Component Storage

Componentsof the circuit--breaker pole

The apparatusmust be stored with itstransport packaging open whilstplaced on beams in a closed (indoor),but ventilated, flood--proof place.

Operating device

The operating device should bestored in the same place as the cir-cuit--breaker, these two sub--assem-blies being inseparable. Check thatthe vacuum packaging is leak--tight.If this has been damaged, proceed asfollows :

The operating device should beplaced so that air can enter throughthe vents of the rear plate and sidepanels.

In order to prevent corrosion dam-agedue to formation of condensation,it is mandatory that the heating circuitbe switched on.
