Scenarii Applicationis
1.elige interruptorem ad nivellum tensionis coniunctum iuxta gradum rete electricitatis
Tensio standard (40.5/72.5/126/170/245/363/420/550/800/1100kV) concordat cum nominali tensio rete electricitatis. Exempli gratia, pro rete 35kV, eligitur interruptor 40.5kV. Iuxta normas sicut GB/T 1984/IEC 62271-100, tensio nominata est certa ≥ maxima tensio operativa rete electricitatis.
2.scenarii applicabiles ad tensionem non standard customizati
Tensio non standard customizata (52/123/230/240/300/320/360/380kV) utitur pro retibus electricitatis specialibus, sicut renovatio veterum retium et scenarii industriales specifici. Propter defectum tensionis standard aptae, fabricantes debent customizare secundum parametras rete, et post customizationem, insulatio et performantia arcus extinguendi debent verificari.
3.consequentes electionis nivelli tensionis errati
Eligendo nivellum tensionis inferius potest causare rupturam insulationis, ducens ad effluvium SF et damnum equipmenti; eligendo nivellum tensionis superius significanter crescit costos, crescit difficultates operationales, et potest etiam resultare in problematis mismatch performance.
The dead tank design of the SF6 Circuit Breaker enhances safety by ensuring that all high-voltage components are housed within a robust, grounded metal enclosure. This design minimizes the risk of accidental electrical faults, as all live parts are completely shielded from external elements. Additionally, this design reduces the possibility of gas leakage, further contributing to safety during operation. Maintenance and inspection can also be performed more safely due to the isolated configuration.
