Sicat 8WL6134 - Siemens

The disconnectors of the product lineSicat® 8WL6134 are outdoor switchingdevices for fixed installations of DC railways.They are used to realize feeders, todisconnect or connect track sections andto connect parallel contact lines.The disconnectors meet the requirementof the EN 50123-1 for a visible isolatingdistance.Features• Very high electric strength due to highcreepage distances and clearances inair• Long service life and low-maintenancedue to corrosion resistant materials andsoil- and water-repellent plastic surfaceof the composite insulators• Higher current load-capacity andenvironmental resistance for certainvariants due to silver-coated contacts• Easy installation and resistant againstvandalism due to shatter-proofcomposite insulatorsElectrical dataNominal voltage [V DC] 3,000Rated insulation voltage [V DC] 4,800Operating current– Sicat 8WL6134-0/-0A/-2/-2A/-2C/-2D/-3/-3A– Sicat 8WL6134-4/-4A– Sicat 8WL6134-5[A][A][A]2,0003,0004,000Creepage distance [mm] 300Clearance in air to earth / above isolating distance– Sicat 8WL6134 -0/-0A/-2/-2A/-2C/-2D– Sicat 8WL6134-3/-3A/-4/-4A/5[mm][mm]180 / 200180 / 90Rated impulse withstand voltageto earth / above isolating distance [kV] 40 / 48Power-frequency withstand voltage, wetto earth / above isolating distance [kV] 18.5 / 22.2Rated short-time current [kA] 40Short-time current duration* only for 8WL6134-5[ms][s]2501*Disconnectors up to 3 kV DCSicat 8WL6134 for overhead contact line systemssiemens.com/mobility

DesignThe disconnectors consist of the followingmain components:• Arcing horns• Contact set with protective covers• Composite insulators• Baseplate with turning leverDue to the use of fittings and bracketsmade of stainless steel a high corrosionresistance is achieved. Therefore the disconnectorsare particularly suitable forthe use in maritime climates. Protectivecovers fitted over the contact sets protectthe contact points additionally againstdirect atmospheric exposures.Minimized maintenanceThe maintenance of the Sicat 8WL6134disconnectors typically confines toinspection, function control and lubricatingof the uncoated contact points.For disconnector types with lustrousgraphite coating on the contact sets,greasing is superfluous due to the selflubricatingcharacteristics of the graphiteportion.If a replacement of the arcing hornsshould be necessary, it can be carried outon site while the disconnectors are stillmounted and the contact line is deenergizedand earthed.12341 Arcing horn2 Contact spring3 Contact blade4 Protective cover5 Earth contact spring*6 Composite insulator7 Turning lever8 Earth contact blade*9 Earth contact support*10 Baseplate* only for disconnector with earth contact5678109Design of the disconnectors examplarily shown at type Sicat 8WL6134-3A2

System integrationThe disconnectors are installed at thetop of contact line poles. A disconnectorbracket is available optionally.Disconnectors are operated via an operatinglinkage either remote controlled witha motor-operated mechanism or with amanually-operated mechanism (not forswitching operations under operatingcurrent).For opening and closing theSicat 8WL6134 disconnectors, electromechanicaloperated mechanisms withlinear stroke and manual operated mechanismswith a stroke of 200 mm are suitable.The following types are available:• Electromechanical operated mechnismin GRP casing, linear stroke• Electromechanical operated mechanismin stainless steel casing, linearstroke• Manual operated mechanismTo minimize electrical wear, the upperoperating linkage can be replaced by avariant with integrated rapid opener. Dueto the rapid opener, opening of the contactset of the disconnector is acceleratedand the extinction of a potentially occurringarc is supported.Disconnector position indication optionOptionally, the Sicat 8WL6134 disconnectorscan be equipped with the Sicat DMSdisconnetor position indication. Incombination with the control of theSicat 8WL6243 and 8WL6244 operatingmechanisms with permanent power supply,the position is registered directly onthe disconnector and is forwarded to thecontrol center.As a matter of course, our portfolio comprisesthe appropriate operating linkages.Electromechanic operated mechanismin GRP casingElectromechanic operated mechanismin stainless steel casingManual operatedmechanismOperated mechanismsExample for system integration withelectro hydraulic operated mechanism inGRP casing3
