开关柜是指按一定的线路方案将一次设备、二次设备组装而成的成套配电装置,是用来对线路、设备实施控制、保护的,分固定式和手车式,而按进出线电压等级又可以分高压开关柜(固定式和手车式)和低压开关柜(固定式和抽屉式)。开关柜的结构大体类似,主要分为母线室、断路器室、二次控制室(仪表室)、馈线室,各室之间一般...
使用电笔来验电,防止触电保安全。 手触笔尾金属点,千万别挨接电端。 笔身破裂莫使用,电阻不可随意换。 保持干燥常清洁,不可接触高压电。 说明 低压验电笔只适用于检验500V以下的低压电,所以绝对不可用它去接触高压,否则将很危险。在使用低压验电笔检验某部位是否有电时,手应接触笔尾的金属点,千万不要去接触...
