基本信息

the metal oxide surge arrester isthe most advanced over-voltage protector. It is widely used as protective devices against switching and lightning over voltages in power electrical systems such as power transformers ,distributors,generators, compensation capacitors. Its core component--resistance slice adopts the material including zinc oxide and many kinds of metal oxides, compared with traditional silicon-carbide arrester, its volt-ampere characteristic of resistance slice has been improved to great degree, as well as the current-transmit ability of resistance slice, as a result, the capability of arrester has been improved basically and thoroughly.12 42kV metal oxide surge arrester Rated Voltage12kV24 kV36 kV42 kVRated frequency48 62Hz48 62Hz48 62Hz48 62HzContinuous operating voltage9.6kV19.2 kV28.8 kV33.6 kVNominal discharge current10kA10kA10kA10kAPower frequency reference voltage12kV24 kV36 kV42 kVLightning impulse residual voltage36kV72 kV108 kV126 kVSteep current impulse residual voltage41.5 kV82.8 kV124.2 kV145 kVSwitching impulse residual voltage30.6 kV61.2 kV91.8 kV107 kVRectangular current withstand 2000μs250A250A250A250AHigh current withstand 4/10μs100kA100kA100kA100kALine discharge class1111Partial discharge10pC10pC10pC10pCCreepage distance369mm655mm894mm1083mmLightning impulse withstand75kV125 kV185 kV200 kVPower frequency withstand(wet 1min)35 kV55 kV80 kV90 kV
