Abstract

The present invention discloses an incoming wire spring operation mechanism for a ring main unit and is aimed at providing the incoming wire spring operation mechanism for the ring main unit which is compact in structure, convenient in operation and long in service life. The incoming wire spring operation mechanism includes a support plate and a support column. The incoming wire spring operation mechanism for the ring main unit further includes a drive shaft, a linkage shaft and a ground cutter shaft arranged on the support plate. An energy storage spring limiting assembly is arranged between drive shaft and the ground cutter shaft, a connection assembly is arranged between the drive shaft and the linkage shaft, and a connection limiting assembly is arranged between the linkage shaft and the ground cutter shaft; interlocking assemblies are arranged between the drive shaft, the linkage shaft and the ground cutter shaft. The incoming wire spring operation mechanism for the ring main unit is applied to the technical field of ring main unit operating mechanisms.

Description

technical field [0001] The invention relates to an operating mechanism of a ring network cabinet, in particular to a line spring operating mechanism for a ring network cabinet. Background technique [0002] The incoming line spring operating mechanism is the operating mechanism of the load switch in the American ring network cabinet. Through this mechanism, the load switch can be electrically and manually operated to realize the functions of "closing", "opening" and "grounding" of the load switch. At present, there are many problems in the field operation that the electric operation transmission is not flexible, and the opening and closing process is prone to failure. Manual operation is laborious, which brings great hidden dangers to the power system. Therefore, research on the structure, high reliability and miniaturization of the operating mechanism has become a hot spot in the development of electric power. Contents of the invention [0003] The technical problem to b...
