HVD1-12
1．General概述
HVD1-12(VS1-12) type indoor AC HV vacuum circuit breaker (hereinafter referred to as circuit breaker) are suitable for 12kV air-insulated indoor switchgears, used as protection and control unit of power equipment of industrial& mining enterprise. Due to the super excellence, it is especially for location where requires the frequent operation of rated working current or multi breaking short circuit current.
The circuit breaker adopts the integrated design of operating mechanism and circuit breaker body, servers as not only fixed installation, but also the handcart unit through equipping with a special propelling mechanism.
HVD1-12 has two main types. Draw-out type is HVD1-12D. Fixed type is HVD1-12F.
Phase distance 150mm , 210mm and 275mm.
Above choice all could be solid embedded type.
HVD1-12型户内交流高压真空断路器是用于12KV空气绝缘的户内开关设备，作为电网设备、工矿企业动力设备的保护和控制单元。由于真空断路器的优越性，尤其适用于要求额定工作电流下的频繁操作，或多次开断短路电流的场所。该断路器采用操作机构与断路器本体的一体式设计，即可以作为固定安装单元，也可以配用专用推进机构，组成手车单元使用。手车式型号为HVD1-12D, 固定式型号为HVD1-12F。行间距为：150mm，210mm和275mm。
以上均可做固封极柱.
