英语翻译所谓的有载真空调压转换开关,实际上是在原来的非有载真空调压转换开关的基础上改造而来,是用特殊材料制造的真空泡 封

The so-called load vacuum adjustable pressure switch, is in fact the original non load vacuum adjustable pressure switch on the basis of transformation and come, is made of special material vacuum bubble closed the original non load vacuum adjustable pressure switch on-load contact, thereby achieving load vacuum adjustable pressure switch load contacts in on-load operation state when only in the vacuum bubble generated by a small number of arc, the resulting heat also rarely; because the vacuum bubble on the arc sealing effect, loaded contact in on-load operation state is generated when a small arc without pollution load vacuum adjustable pressure switch transformer oil, thus all configure load vacuum adjustable pressure switch of electric furnace transformer is not configured, on-load tap switch on-line oil filter ( China not only so, all the world ); the electric furnace transformer if by using load vacuum adjustable pressure switch pressure regulation cases still configuration of on-load tap switch on-line oil filter, in fact of on-load tap switch on-line oil filter is useless, is a waste of resources, and increase the daily maintenance and future The old equipment follow-up investment
