| 摘 要： | 在冬季SF6断路器由于环境温度的变化,断路器中SF6气体的压力也随着变化.由于一天内频繁出现了SF6气体压力低于或高于报警压力的现象,压力超过0.65MPa时泄压,而压力低于0.53MPa时开始补充气体.这种频繁的泄压、补气不仅浪费SF6气体,而且还使SF6气体的纯度下降,从而影响了SF6气体的绝缘性能.对断路器和人员...

| Abstract: | Due to environmental temperature change in winter,the pressure of SF6 gas in SF6 circuit breaker is changed.The SF6 gas pressure was always higher or lower than the alarm pressure in a day,when the pressure higher than 0.65MPa,decompression,and when the pressure lower than 0.53MPa,gas charging.This phenomenon not only wastes the SF6 gas,but also reduces the SF6 pureness,thus affect the insulativity of SF6.The circuit breaker and staffs are also affected.For the company,the drop-out current capacity of SF6 c... |
