我厂使用的SN_8及SN_(10)型油断路器为国家标准系列产品。由于这两种油开关动触头在下部,油开关下部的拐臂是一个传动点,怎样在有传动要求的拐臂处,达到无渗漏的要求,历来是各使用单位的老大难问题。我厂自1977年以来,在学习兄弟单位经验的基础上,将原制造厂的弹簧夹紧油封(见图一),改造成为空腔多道油封(见图二),目前,全部SN_8、SN_(10)型油开关一次
The SN_8 and SN_ (10) oil circuit breakers used by our factory are national standard products. As these two oil switch moving contacts in the lower part of the lower part of the oil boom is a transmission point, how the transmission requirements of the crank arm, to achieve no leakage requirements, has always been the use of units of the most difficult problem. Since 1977, based on the experience of our brother unit, our factory transformed the spring-loaded oil seal of the original manufacturer (see Figure 1) into multi-channel oil seal in the cavity (see Figure 2). At present, all SN_8 and SN_ (10) type oil switch once
