To reduction operating personnel and maintenance personal life danger is caused in operation or maintenance process.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the chain structural schematic diagram in the surface of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings with preferred embodiment to the on-load switch machine of the middle pressure AC distribution ring main unit of the utility model
The chain further details of explanation in surface on structure.
Referring to Fig.1, the utility model provide it is a kind of it is middle pressure AC distribution ring main unit on-load switch mechanism on surface
Operating shaft baffle 1 that is chain, including being arranged between distribution ring main unit breaking-closing operating axis and ground connection operating shaft, the operating shaft
Baffle 1 is connected with baffle rack 2, and is moved left and right by the drive of baffle rack 2, can block breaking-closing operating axis or ground connection operation
