Description
Technical field
This utility model belongs to the technical field of sub-connecting switch of transformer, more particularly, to a kind of action bars of shunting switch.
Background technology
It is hollow shape inside the manipulation knock-off joint of existing shunting switch, it is paper phenol that stick typically adopts insulant
Pipe or glass fiber pulling or winding pipe, its cylindrical (inside joint) or endoporus (encasing joint in outside) are coordinated simultaneously with stick
Coupled by pin, because the electrode size of pin is less, the insulation breakdown of stick is frequently experienced in the inside and outside top layer of pole,
Climb electricity along face and cause insulation breakdown or shelf depreciation particularly by the stick inwall at pin, especially in higher electricity over the ground
The occasion of pressure.And common method is to increase annular electrode and do not improve the exhausted of tubular stick inwall in the outside of joint
Edge, insulation fault is more, and once having an accident, it will cause the damage of transformator to cause direct in a large number and indirect loss.
Content of the invention
Technical problem to be solved in the utility model is, for above-mentioned problem, to provide a kind of shunting switch
Action bars, improve shunting switch main shaft over the ground with insulation between phase and phase.
This utility model solves above-mentioned technical problem and be the technical scheme is that a kind of action bars of shunting switch, bag
Include top connection, lower contact and mandrel, described mandrel is hollow tubular structures, the upper and lower ends of mandrel respectively with described top connection and
Lower contact be connected, the top of top connection is connected with operating mechanism, the bottom of lower contact be connected with Switch main body it is characterised in that
The junction of the upper and lower ends of mandrel endoporus is respectively provided with interior electrode and lower interior electrode.
By such scheme, described top connection and lower contact all include outer tube and external electrode, and the upper and lower ends of described mandrel are divided
Do not insert in the outer tube of upper and lower joint, and be connected with outer tube and described upper and lower interior electrode by bearing pin.
By such scheme, described upper and lower interior electrode is " u " shaped cylindrical structure.
By such scheme, described top connection includes outer tube and upper external electrode, and described lower contact includes lower outer tube and lower outer
Electrode, the bottom of top connection is concordant with the arc tips of upper interior electrode to be arranged, and the arc of the top of lower contact and lower interior electrode is held level with both hands
Neat setting.
