Abstract
A kind of pole vacuum switch tube, the moving conductive rod comprise moved end cover plate, stretching out in the middle part of the cover plate of moved end, fairlead is set with outside moving conductive rod, the bellows of taper is housed in the outer cover of fairlead, moving conductive rod, this bellows one end is welded with moving conductive rod outer surface, the other end welds with the outer surface of moved end cover plate, forms airtight cavity in bellows interior, and this cavity is vacuum chamber.The utility model can solve vacuum switch tube inside well and produce condensation, and resin or silica gel flow into that vacuum switch tube is inner and vacuum switch tube that is that cause scraps this two problems.
Description
Technical field
The utility model relates to a kind of technical field of power equipment, particularly relates to a kind of pole vacuum switch tube.
Background technology
In existing vacuum switch tubular construction, between moving conductive rod and the bellows of inside, there is a cavity, between moving conductive rod and fairlead, have larger space, so this cavity communicates with air.When making pole, this part cavity cannot by sealing, and condensation can produce the inside at vacuum switch tube equally, thus destroys insulation.And if resin or silica gel flow into this cavity when building, then moving conductive rod cannot move, thus causes vacuum switch tube to be scrapped.
Utility model content
For solving the problem, the utility model provides a kind of pole vacuum switch tube.
The technical solution of the utility model is: a kind of pole vacuum switch tube, the moving conductive rod comprise moved end cover plate, stretching out in the middle part of the cover plate of moved end, fairlead is set with outside moving conductive rod, it is characterized in that: the bellows that taper is housed in the outer cover of fairlead, moving conductive rod, this bellows one end is welded with moving conductive rod outer surface, the other end welds with the outer surface of moved end cover plate, forms airtight cavity in bellows interior, and this cavity is vacuum chamber.
The utility model can solve vacuum switch tube inside well and produce condensation, and resin or silica gel flow into that vacuum switch tube is inner and vacuum switch tube that is that cause scraps this two problems.
Accompanying drawing explanation
Fig. 1 is this pole vacuum switch tube front view.
In figure 1, moving conductive rod, 2, bellows, 3, fairlead, 4, moved end cover plate.
Embodiment
See Fig. 1, a kind of pole vacuum switch tube in figure, the moving conductive rod comprise moved end cover plate, stretching out in the middle part of the cover plate of moved end, fairlead is set with outside moving conductive rod, it is characterized in that: the bellows that taper is housed in the outer cover of fairlead, moving conductive rod, this bellows one end and moving conductive rod outer surface welding machine, the other end welds with the outer surface of moved end cover plate, form airtight cavity in bellows interior, this cavity is vacuum chamber.Moving conductive rod 1 does axial motion under the constraint of fairlead 3, one end seal welding of bellows 2 is on moving conductive rod 1, the space that moving conductive rod 1, bellows 2 and moved end cover plate 4 surround, on moved end cover plate 4, is evacuated by other end seal welding, completes envelope row technique.
