10kv 12kv outdoor vacuum circuit breaker ZW20-12 with permanent magnet AC 50/60Hz
ZW20-12F (M)outdoor high-voltage inteligent (permanent magnet)vacuum cicuit breaker is outdoor high-voltage switchgear with rated voltage of 12kV and three-phase AC 50/60Hz.Mainly used for breaking and closing the load curent,overload curent and short circuit curent of the power system.It is suitable for the protection and control of substations,industrial and mining enterprises,and urban and rural distribution networks,especialy for places with frequent operations and urban network automatic distribution networks.This product is matched with the controlle,can meet the requirements of the distribution automation system,and can reliably and effectively complete the traditional recloser function.It adopts mature box seal structure,has good sealing performance,so thatit is notaffected by the external environment,is a maintenance-fre product.
The spring operating mechanism or permanent magnet operating mechanism has high action reliability and is a good product for the pole breaker.
Structural features
◆ Miniaturized design;
◆ The box has an inverted button structure,full sealing,simple sealing effect,and high anti-pollution level;
◆ The transmission mode is novel,simple and reliable;
◆ The main components are sealed in the box to achieve real maintenance-free;
◆ External voltage transformer and isolating switch can be installed.
Operating environmental conditions
◆Working environment temperature:no more than 40℃;daily average temperature does not exceed 35℃;minimum ambient air temperature is-25℃;
◆ Relative humidity of air:daily average value is not more than 95%,monthly average value is not more than 90%;daily average value of water vapor pressure is not more than 2.2kPa,monthly average value is not more than 1.8kPa;
◆ Altitude:no more than 2000m;
◆ The surrounding area is not obviously polluted by dust,smoke,corrosive and/or flammable gas,steam or salt spray;
◆ Vibration or ground motion from outside of switchgear and control equipment can be ignored;
◆ The amplitude of induced electromagnetic interference in the secondary system does not exceed 1.6kV
