Abstract
The utility model discloses a flexible connection for a vacuum arc-extinguishing chamber. A conventional connection is a spring touch finger or square flexible connection block which has problems of poor contact, limited movement, and uneven force at a movable end. The flexible connection is arranged between a movable conducting rod and a stay wire end in the vacuum arc-extinguishing chamber and is equipped with annular flexible copper sheets stacked in 2 to 20 layers. The outer rings of the annular flexible copper sheets in every two adjacent layers are spaced apart from each other by an outer spacer ring. The inner rings of the annular flexible copper sheets in every two adjacent layers are spaced apart from each other by an inner spacer ring. The outer rings of the annular flexible copper sheets and the outer spacer rings are welded. The inner rings of the annular flexible copper sheets and the inner spacer rings are welded. The inner rings and the movable conducting rod are welded. The outer rings and a wiring end are welded. The flexible connection resolves a problem of fracture caused by sliding friction of the spring touch finger and uses annular design such that the movable conducting rod bears uniform force and the service life and the reliability of the flexible connection are increased.
Description
Technical field
What the present invention relates to is that vacuum interrupter is flexible coupling, and is a kind of connection of electric moving component, belongs to electrical engineering technical field.
Background technology
At present, the moved end of indoor HVAC vacuum circuit breaker routine connects, employing be all spring touch finger or the square piece that is flexible coupling.The subject matter that spring touch finger pattern exists is: after spring wear and rupture, exist and eject stopper slot, bring the faults such as loose contact and limitation of movement.The subject matter that square connection exists: the moved end lateral stress that deformed end is brought that is subject to being flexible coupling, causes moved end unbalance stress.Therefore, providing a kind of vacuum interrupter to be flexible coupling, is to improve the requisite measure that HVAC vacuum circuit breaker moved end connects useful life and reliability.
Summary of the invention
The object of the invention is to manufacture and design a kind of vacuum interrupter and be flexible coupling, for connecting moving conductive rod and lower terminals, to improve the conducting system structure of vacuum interrupter, reach moved end stressed evenly, the motion fault that does not have spring touch finger fracture to bring.
The object of the invention is to reach like this: vacuum interrupter is flexible coupling, comprise moving conductive rod of vacuum arc extinguish chamber and terminals, between moving conductive rod of vacuum arc extinguish chamber and bracing wire end, be provided with the ring-type soft copper sheet that stacks into 2-20 layer, between every adjacent two-layer ring-type soft copper sheet outer shroud, be separated with the outer spacer ring of one deck, in every adjacent two-layer ring-type soft copper sheet, between ring, be separated with spacer ring in one deck, the outer shroud of annular soft copper sheet and 1 welding of outer spacer ring, the interior ring of annular soft copper sheet and the welding of interior spacer ring, respectively by interior ring and moving conductive rod welding, outer shroud and terminals weld again.
Take the present invention of above-mentioned measure, be flexible coupling and adopt after solder technology, the sliding friction of having eliminated spring touch finger causes the problem of fracture, has adopted annular design simultaneously, and moving conductive rod is stressed evenly, has improved the life and reliability being flexible coupling.
Below the invention will be further described by reference to the accompanying drawings again.
four. accompanying drawing explanation
