这个耐压怎么打?
EN60730中有这样一句:For the test of full-disconnection and micro-disconnection, contacts are opened automatically or manually and tested as soon after opening as possible to ensure that the contact separation and the supporting insulation are satisfactory.这样的耐压大500V,这是指打那里的耐压?该怎么打?求高人指点 期待高手没听过这个标准 唉 估计很少人做这个标准了 控制器断开后在两极之间施加500V,考核控制器是否有效断开
