How to divide low-voltage electrical appliances and high-voltage electrical appliances!

2020-08-24

How to divide low-voltage electrical appliances and high-voltage electrical appliances: 1. Low-voltage electrical appliances: refers to the low-voltage electrical equipment that we refer to in our daily life refers to the equipment that undertakes on-off control in the 380/220V power grid. Low-voltage electrical appliances are components or equipment that can be manually or automatically connected and disconnected according to external signals and requirements to realize the switching, control, protection, detection, transformation and adjustment of circuits or non-electrical objects. Control appliances according to the level of its working voltage, with AC 1000V, DC 1500V as the boundary, can be divided into two categories of high-voltage control appliances and low-voltage control appliances. In general, low-voltage electrical appliances can
