Indoor Sealed High Voltage Vacuum Breaker Supplier

VS1 Indoor Vacuum Breaker Product DescriptionVS1 indoor medium voltage Vacuum Circuit Breaker is a three-phase AC 50Hz ,rated voltage 6KV,12KV,24KV switch equipment of power system.Breaker adopts the integral design of the actuating mechanism and the breaker body, which can be used as a fixed installation unit or as an individual VCB carriage together with handcart. They have a long life expectancy. There is no adverse effect on the vacuum, even from frequent switching of operating and short-circuit currents.AdvantagesVS1 type VCB consist of operating mechanism and arc-extinguish chambers in front-back arrangement, its main conductive circuit is floor model structure. The vacuum arc-extinguish chamber is fixed in a vertical cannular insulation column made of epoxy resin by APG technology, therefore with high anti-creepage function. Such structure design greatly reduces the accumulation of dusts on the surface of vacuum arc- extinguish chamber, it not only can prevent the vacuum extinguish chamber from outside influences, but also can ensure to present high resistance state against the voltage effect even in warm-wet climate or heavy pollution environment.1 - with reliable interlock functions, suitable for frequent operation2 - low noise and energy consumed3 - simple and robust construction.4 - high operating reliability 5 - mechanical durability of switch : 20000 times, etc Fields of application1 - Transformers and distribution substations2 - Generator control and protection3 - Capacitor bank control and protection, etcMechanical parametersNo.ItemUnitDate1Rated voltageKV12242Clearance between open contacts  mm11±113±13Over travel of moving contact3.5±0.53.5±0.54Three poles asynchronous time at openingms≤2≤25Moving contact bounce time at closingms≤2≤26Average opening speed  m/s0.9-1.20.9-1.27Average closing speed0.6-0.80.6-0.88Connecting pressure of close contacts   N20kA25kA31.5kA40kA20kA25kA31.5kA40kA2000±2002400±2003100±2004250±2002000±2002400±2003100±2004750±200Main characteristicsNo.ItemUnit 1Rated voltageKV12242Power frequency withstand voltage42653Lightning impulse voltage(peak value)751254FrequencyHz50505Rated current A6301250630 1250  1600 2000 2500 31501250 1600 2000 2500 3150 40006301250630 1250 1600 2000 1600 200 25006Short circuit breaking currentkA20/2531.5402525/31.531.5/407Thermal stability currentkA20/2531.5402525/31.531.5408Dynamic stable currentkA50/638010063801009short-circuit making current kA50/6380100638010010Rated current breaking timeTimes200002000011Short circuit breaking current  timesTimes≤50≤3012Operation voltageVAC/DC 110/220AC/DC 110/22013Input powerW707014Storage time s≤15≤15153 phase non-synchronousms≤2≤2/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
