Circuit breaker huu wa 40.5kV ni muhimu kwenye gas-insulated switchgear (GIS), unatumia SF6 gas kwa insulation na arc-quenching performance bora. Imejenga kwa grid za medium-to-high voltage, inatoa breaking na switching operations mara tu, zenye uaminisho ili kuhifadhi dhidi ya overcurrents na short circuits.
Umbayo wake ndogo na umekufunga hutokana na footprints, hutoa resistance dhidi ya environmental factors (dust, moisture, extreme temps), na hongeza matumizi ya maintenance. Imejulisha na advanced mechanical interlocks na smart monitoring compatibility, inaweza kuhakikisha safe, precise operation—critical kwa substations, urban power grids, na industrial facilities. Inafanikiwa IEC 62271 na GB standards, inatoa long service life na stable performance, ikibidhi kuwa chaguo la uaminisho kwa efficient grid management.
Msimbo mkuu ni 630A-20kA (4S) na 25kA (3S), na mechanical life ni 10000 times. Grounding circuit 20kA (2S), mechanical life 2000 times.
Considerations for the use of environmental conditions
Altitude haipunguze zaidi ya 1000m, na crack degree haipunguze zaidi ya 8 degrees. Pollution level: ll
Environmental temperature ya product ni -40 degrees ~+140 DEG C, relative humidity haipunguze zaidi ya 90% per day, na average haipunguze zaidi ya 90% per month;
Installation site ya frequent and violent shock, water vapor, chemical corrosion deposition, salt fog, dust, dirt na fire, ambayo huathiri sana performance ya mechanism, hayafaa kwa installation ya explosive dangerous installations.
