| SF6 bottle type chopper of the LW30-126 T high pressure exchanges is chopper and electric current with each other the feeling machine organic combination put out Hu room together the level equip in the aluminum metal alloy hull body of connecting the ground and go together with to hold motive to reach with a the set CT26 type spring coil, electric current with each other feeling machine decoration at two line set underneath for taking care of, structure simple tightly packed, match a switch have no the oil turn request; And product all important parts are to adopt number to control, process equipments like center, etc to process, the international brand bearings(for example brands, such as IKO, INA and SKF...etc.) of bearings adoption import, the machine life span can reach to 10000 times, can promise that the service life is for 30 years. The product is applicable to three electric power system of 50 Hz,66?110 kV of mutually communicating, can used for control, protection and diagraph of system as well as used for the situation that opens to match a capacitor set.This thesis particularly instantaneous opening/closing speed/work formulas have revised according to relevant references for single pressure puffer-type been deduced and SF6 circuit breakers with rated and related parameters and their meanings involved are clarified as well. The final comparison is as fellow:computed opening speed VS design opening speed:Vgf=4.45(m/s) VS Vgf=4.3±0.5(m/s); computed closing speed VS design closing speed:Vgh=5.10(m/s) VS Vgh=5.0±0.5(m/s). The comparison shows that the design parameters are reasonable and the methods and approaches adopted in this paper are highly reasonable and creditable. And closing work VS opening work: Wh>Wf (Wh=1861.49(J), Wf=1552.51(J), such result shows the closing process of mobile electrode is creditable[1]. |
