近几年来,我国电力牵引供电系统,SF_(?)断路器发生爆炸事故已达30多起,石家庄供电部门启用该断路器五年间,即发生六次爆炸。爆炸后释放多种氟化物,严重威胁工人身体健康,应引起高度重视,为吸取教训,兹将 SF_6断路器产生的有害气体,接触机会,毒性反应及预防措施探讨如下。
In recent years, China’s electric traction power supply system, SF_ (?) Circuit breaker explosion has reached more than 30, Shijiazhuang power supply sector to enable the circuit breaker five years, that is, six explosions. The release of a variety of fluoride after the explosion, a serious threat to the health of workers, should pay close attention to, for the sake of lessons learned, SF6 circuit breaker will produce harmful gases, exposure, toxicity and preventive measures are as follows.
