Load - ratio voltage regulation of transformer is the voltage regulation , which has larger regulating scope and less investment and higher speed and well effect in power - on conditions
这种调压措施，调压范围大，投资少，效果好，调压范围一般为15及以上。
This ill preclinical accident is differ , it is 15 days commonly , better can amount to a few months or go up year of above , the poisonous force of preclinical accident and infection , place is concerned
本病的潜伏期长短不一，一般为15天，长者可达数月或上年以上，潜伏期的长短和感染的毒力、部位有关。
On - load tap - changer of transformer can work under load , transfer quickly , change one class voltage about 3 - 6 ms each time ; switch can be operated by hand or electrically - driven and distant place operate while being electronic too , easy to realize automatic management ; transfer and keep relatively heavy range is generally more than 15 % ; switch and voltage transformer structure are more complicate than others , make man - hour and material increase , the cost is relatively high
变压器的有载调压能带负载调压，调压速度快，每调换一级电压约3 6s ；开关可手动、电动操作，也能远方电动操作，便于实现自动化管理；调压范围较大，一般为15以上；开关和变压器结构比无励磁调压的复杂，制造工时和材料增多，成本较高。
