Independently bistable spring mechanism allows reliably and the assembling of sealing.Can under the situation of the spring assembly of not dismantling pretension, carry out attended operation in addition.
Can be independent of that the debugging that whole break-make system carries out driver element is prepared, the especially test of secondary electric device and the function of driver element.
The structure of driver element can the Modularly scale.Through build (verbauen) different combinations part (Satz) at the spring assembly place, can adjust the stored energy of spring assembly.Through building the different combinations part, can adjust switch over travel (Schaltweg) and response time equally at the lever place of processing by metal level.
Being applied under the minimum inertia of input interface place hollow stem having a profile (Pfahlprofil) provides high torque (HT).
Preferably use rolling bearing for all important supportings.If need the dispersion (Streuung) of machinery and the automatic reaction time of rubbing and following, also can use sliding bearing.These sliding bearings cause material cost lower when making driver element.
Can use the material of processing by a plurality of interconnective metal levels for housing and other fundamental parts.Also can use material that cut apart with a knife or scissors or casting.Yearly output is depended in the use of various materials.For the plate of making housing can use metal level, wherein whole geometry can be by the different metal layers manufacturing.
The parts of plate that are used for plate or the right on the housing left side can be identical, and wherein they only pile up with different order.Metal level allows the scale (Skalierung) of the structure of driver element according to its each requirement equally.
Load for driver element is big more, then must select a greater number of interconnective metal levels and/or the thick more plate that is used for housing.
Integrated buffer unit in the middle of preferably being provided with.The buffer unit that when hanging down about the requirement of dynamic motion, especially in the gas compartment of insulation, disperses can be replaced.This causes better, i.e. use possibility more stable, electric insulation.Therefore can avoid because the typical pollutant sources that the wearing and tearing of buffer unit cause.
About the having relatively high expectations of dynamic motion the time,, support the buffer unit that disperses through reducing individual buffering requirement.
Described here driver element can be used for the switchgear of all gas, air or vacuum insulation.The different structure that has the driver element of identical employed part is possible.Spring assembly is possible with the separating of position of axle.It is possible more easily assembling spring assembly, more safely safeguarding and more easily change.GIS guarantees that perhaps the same transfiguration of dismounting of the switch of ground connection is prone to.
