户内真空断路器中型号里字母和数字各代表什么？
户内真空断路器中种类很多种，下面我们就来分析一下最常见的吧
There are many kinds of indoor vacuum circuit breakers. Let's analyze the most common ones.
户内真空断路器首字母“Z”代示带有真空灭弧室的断路器
The initials "Z" of indoor vacuum circuit breakers represent circuit breakers with vacuum interrupters
其次“N"代表户内或者室内用，了解更多：http://www.zjxuli.com/ 咨询：18958858230
Second, "N" for indoor or indoor use, learn more: http://www.zjxuli.com/consultation: 18958858230
再是数字登场它是代表设计型号，比如说“63”，“28”，“73”等
And then the digital debut is representative of the design model, such as "63", "28", "73" and so on.
后面的额定电压比如说“12”KV,“24”KV等
Later rated voltages such as "12" KV, "24" KV, etc.
后面紧跟首就是额定电流，如：“400”，“630”，“1250”等
The rated current, such as "400", "630", "1250" and so on, is immediately followed by the rated current.
再次是开断额定电流，如：“20”，“25”，“31.5”等
The third is to turn off rated current, such as "20", "25", "31.5" and so on.
不过户内型号也有很多变化，它与柜型的匹配变化而变化，有固定式和手车式两种，也不一样，如ZN63和VS1是同样的东西，叫法不一样而已。
However, there are also many changes in the indoor model, which changes with the matching of cabinet type. There are two types of fixed type and handcart type, and they are also different. For example, ZN63 and VS1 are the same thing, and their names are different.
综上所述ZN63-12/630-25真空断路器的型号的含义为设计型号63的户内真空断路器，电压为12KV，电流为630A,开断电流为25KA。
In summary, the model of ZN63-12/630-25 vacuum circuit breaker mentioned above means the indoor vacuum circuit breaker of design type 63, which has 12 KV voltage, 630 A current and 25 KA interruption current.
