问题1答案： ①can increasethecapacityofpower generation and supplyof equipment,theequipmentcanbe fully utilized. ②can reducethevoltage lossofthepowersystemtoreducevoltage fluctuations, improve voltage quality. ③to reducethecurrentinthetransmission, substation,power distributionequipment,thereby reducing thepower lossofthepower transmissionprocess. ④to reducecorporateelectricity costs,reduce production costs. 问题2答案： Compared to single phase, three phase power transmission costs low transmission power. Moreover, the simple structure of three-phase motor, high reliability, extensive use in industry, three-phase power phase motor can be driven directly, saving a lot of converter circuit. 问题3答案： Was originally intended to prevent the protective measures taken by the electric or electronic devices such asbeing struck by lightning,thunder and lightning of thelightning current through the lightning rodis introduced intothe earth,and thus play the role of protecting the building.Meanwhile, thegroundis alsoan effective meanstoprotectthepersonal safety,whenfor some reasoncaused by thephase line(such aswire insulation is poor,the aging) and equipmenthousingtouch,equipmentenclosurewillbedangerousvoltage, whichfault currentwillbegeneratedthroughthePE wiretotheearth,and thusplay a protective role.
