手车式户内高压真空断路的灭弧原理
VS1-12/M断路器(配永磁操动机构)采用真空灭弧室,以真空作为灭弧和绝缘介质,灭弧室具有极高的真 VS1-12真空断路器,空度,当动、静触头在操动机构作用下带电分闸时,在触头间将会产生真空电弧,同时由于触头的特殊结构,在触头间隙中也会产生适当的纵磁场,促使真空电弧保持为扩散型,并使电弧均匀分布在触头表面燃烧,维持低的电弧电压,在电流自然过零时,残留的离子、电子和金属蒸汽在微秒数量级的时间内就可复合或聚在触头表面和屏蔽罩上,灭弧室断口的介质绝缘强度很快被恢复,从而电弧被熄灭,达到分断的目的,由于该真空断路器采用磁场控制真空电弧,因而具有强而稳的开断电流的能力。
