概述/Specification

JN22-40.5/31.5型户内高压接地开关(以下简称接地开关)是公司开发的新产品。其性能符台国家标准GB1985-2004《交流高压隔离开

关和接地开关》国家标准，适用于三相额定电压405kV,交流50Hz的电力系统，可与KYN61-405高压开关柜及其他型号高压开关柜配套使用，

作为高压电器设备检修时接地保护用。JYN22-40.5/315型户内高压接地开关是上述接地开关基础上改进，结构简洁紧凑，性能一致，便于小角

度操作，与JN15-12系列相同，可采用JN15-12的接连和传动件。

JN22B-40.5/31.5 series indoor high voltage(HV)earthing switch absorbs advanced new technical from domestic and abroad.It confirms to GB1985-2004 <AC HV DISCONNECT SWTCH AND EARTH SWITCH>standard.And applies to three-phase rated voltage 405kV.AC50/60Hz power system.It cansupport the use of KYN61-405 HV switch panel and other models,the foundation is protect the HV electric equipments when repair or maintenance.JYN22-

40.5/31.5 series HV earthing switch is revised and update on the base of the above model,its structure is more simple and compact,best performance andeasy operate with small angle.It is same with JN15-12,the connect and driving medium are in common use.
