HONLE ZW20A Outdoor High Voltage AC Vacuum Circuit BreakerOverviewZW20A outdoor high voltage AC vacuum circuit breaker is Honle vacuum circuit breaker series.The new equipment in the ZW20A outdoor high voltage AC vacuum circuit breaker, with a rated voltage of 12 kV, is suitable for overhead lines and industrial and mining enterprises, power plants, substations and other places of this voltage level, under normal operating conditions and the technical parameters of the circuit breaker. It can meet the operation requirements of various protections of the system under the running state of the power grid, including extremely excellent operation performance under the occasions of closing and breaking short-circuit current. The product meets the requirements of automatic reclosing and has reliable operationFeatures of high performance and long electrical service life.Working ConditionsAmbient air temperature: -40°C- +40°CAltitude: ≤2000mRelative humidity: daily average value is not more than 95%; monthly average value is not more than 90%Wind speed: ≤ 34m/s (equivalent to 700pa on the cylindrical surface)Pollution level: ≤IVProduct performance standardsThe manufacture of ZW7A outdoor high voltage AC vacuum circuit breaker complies with the following standards and specifications:IEC 62271-100 High Voltage AC Circuit Breaker.GB/T 11022-2011 High-voltage switchgear and control equipment standard common technology.GB 1984 high voltage AC circuit breaker.GB 311.1 Insulation coordination of high-voltage power transmission and transformation equipment.The main technical parametersProjectUnitReferenceRated voltageKV12Rated insulation levelLightning impulse withstand voltageKV751min power frequency withstand voltageKV42Rated frequencyHZ50/60Rated currentA630/1250Rated short-circuit breaking currentKA16/20/25Rated short-circuit making current (peak value)KA40/50/63Rated short-time withstand currentKA16/20/25Rated peak withstand currentKA40/50/63Rated short-circuit durations4Breaking times of rated short-circuit currentTimes30Mechanical life M2 Classweightkg145Mechanical characteristic parametersProjectUnitReferenceContact opening distancemm9±21 Contact overtravelmm3±1 Average closing speedm/s0.6±0.2Average opening speedm/s1.2±0.2Bounce time of contact closingms≤2 Different timing of contact closing and openingms≤2 Loop resistance of each phaseμ Ω  Switch ≤200 Isolation ≤50 Dynamic and static contact allowable wear cumulative thicknessmm3Operating mechanismThe spring operating mechanism of the circuit breaker stores energy through manual operation, no need. Any external power supply is required, which is convenient and reliable. After the energy storage is in place, it can be operated by closing and openingThe handle is used for closing operation. When in the closing position, it can be accessed directly through the closing and opening handles. The opening operation is performed, and no energy storage is required for each opening operation.DimensionsCompany Information•FAQQ 1. what's the payment terms? A.
