Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail, it should be understood that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, one embodiment of the present embodiment is a kind of transformer contact tube, packet
Include contact tube ontology 1, the contact tube ontology 1 flat, intermediate hollow round tube shape in both ends, both ends are flat be in order to
Facilitate the full contact of entire contact tube and transformer lugs, optimal conductive effect is reached with this, and centre is set as
Hollow circular tube is used for while improving electric conductivity in order to which generated vortex heat in contact tube is effectively reduced,
Copper product is saved, the heat dissipation performance of contact tube is accelerated.The flat both ends of the contact tube ontology 1 are vertically arranged with through-hole 2,
2 surrounding of through-hole is provided with gasket groove 3, and gasket groove 3 and the central axes of through-hole 2 overlap, this design, which is to further ensure that, to be led
The rigid contact of electrolytic copper pipe and transformer lugs only just can guarantee that contact tube is perfectly realized after the two is in close contact
Its electricity connection function, once the two is not in contact with good generation contact tube dropping situations, it is most likely that and cause short circuit or lead disconnected
It splits, transformer is even burnt out when serious.Further, the hollow circular tube outer wall of the contact tube ontology 1, which is vertically arranged with, leads
Oilhole 4, oil guiding hole 4 are communicated with the inner cavity of hollow circular tube, this design is that enter transformer insulation oil can by oil guiding hole 4 leads
In electrolytic copper tube body 1, and achieve the purpose that contact tube effectively radiates by the mutual circulation with external transformer insulating oil.
