Abstract
The utility model relates to an electric power security domain especially relates to titanium alloy thalposis gasket. Contain the gasket body, gasket body border contains the dog -ear, direction of dog -ear orientation. Adopt as above technical scheme the utility model discloses, there is following beneficial effect for prior art: this patent can be according to the rising that connects the temperature, increases the elasticity of gasket automatically, reduces to connect contact resistance, effectively alleviates to connect and generates heat. Also can active absorption mechanical oscillation, avoid because of the bolt looseness that mechanical oscillation caused, ensure that the pretightning force is lasting reliable.
Description
Technical field
The utility model relates to electric power safety field, particularly relates to titanium alloy warming pad.
Background technique
The defect of prior art is: Power tabs electric current flows through and often occurs conductor joint heating phenomenon.Conductor joint heating can cause electrical network Electricity customers security incident to occur.
Model utility content
The object of model utility: in order to provide a kind of titanium alloy warming pad of better effects if, specific purposes are shown in multiple substantial technological effects of concrete implementation section.
In order to reach as above object, the utility model takes following technological scheme:
Titanium alloy warming pad, is characterized in that, comprise shim body, and described shim body edge comprises knuckle, and described knuckle facing one direction.
The further technological scheme of the utility model is, described shim body is circular.
The further technological scheme of the utility model is, described shim body comprises lines, and lines can by the bolt top compacting of connection bolt.
The further technological scheme of the utility model is, also comprises lines below described bolt top.
The further technological scheme of the utility model is, described knuckle comprises multilayer knuckle, and knuckle also comprises knuckle.
The further technological scheme of the utility model is, the thickness of described knuckle is greater than the thickness of shim body.
The further technological scheme of the utility model is, described bolt middle top comprises cavity, and cavity comprises opening at bolt top.
Adopt the utility model of as above technological scheme, have following beneficial effect relative to prior art: this patent according to the rising of connector temperature, can increase the elastic force of pad automatically, reduces junction contacts resistance, effectively alleviates conductor joint heating.Also effectively can absorb mechanical vibration, avoid the bolt looseness because mechanical vibration cause, guarantee that pretightening force is reliable lastingly.
Accompanying drawing explanation
In order to further illustrate the utility model, be described further below in conjunction with accompanying drawing:
Fig. 1 is the structural representation that model utility preparation is installed;
Fig. 2 is the mounted structural representation of model utility;
Reaction condition structural representation under the model utility high-temperature condition of Fig. 3 position;
Wherein: 1. pad; 2. knuckle; 3. installation position; 4. connection bolt; 5. bolt top; 6. bending part.
Embodiment
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
Titanium alloy warming pad, is characterized in that, comprise shim body, and described shim body edge comprises knuckle 2, and described knuckle facing one direction.The technique effect of the essence that the technological scheme at this place plays and implementation procedure thereof are as follows: composition graphs 1 is to Fig. 3, and when after heating, connector temperature exceedes warming pad phase transition temperature, and pad exports larger elastic force automatically, joint is connected more fastening.
Described shim body is circular.The technique effect of the essence that the technological scheme at this place plays and implementation procedure thereof are as follows: as preferably, and the structure of shim body can be square also can be circular, and the circle at this place is not construed as limiting.
Described shim body comprises lines, and lines can by the bolt top compacting of connection bolt.The technique effect of the essence that the technological scheme at this place plays and implementation procedure thereof are as follows: the lines at this place can play the effect of increasing friction force, make shim body can by stable fixing.Also lines is comprised below described bolt top.
Described knuckle comprises multilayer knuckle, and knuckle also comprises knuckle.The technique effect of the essence that the technological scheme at this place plays and implementation procedure thereof are as follows: knuckle comprises multilayer, so can conveniently be out of shape.The thickness of described knuckle is greater than the thickness of shim body.
Described bolt middle top comprises cavity, and cavity comprises opening at bolt top.The technique effect of the essence that the technological scheme at this place plays and implementation procedure thereof are as follows: can also add water by this opening, so can conveniently dispel the heat.
In a creative way, each effect above independently exists, and can also complete the combination of the above results with a nested structure.
It is clear that the technique effect that above structure realizes realizes, if do not consider the technological scheme of adding, this patent title can also be a kind of pad.Not shown part details.
It should be noted that, multiple schemes that this patent provides comprise basic scheme own, separate, mutually do not restrict, but it also can combine when not conflicting mutually, reaching multiple effect and jointly realizing.
This patent automatically according to temperature variation, can export different elastic force, reduces junction contacts resistance.The position such as various jointings in electric power system electric line uses, can be real to realize joint area non-maintaining.There is following outstanding effect:
energy-saving safe:
After connector temperature exceedes pad phase transition temperature (40 DEG C ± 5 DEG C), junction contacts resistance ratio conventional spacers joint declines more than 10%, saving power, avoids the overheated security incident caused of joint to occur.Because warming pad uses titanium alloy material, without magnetic, so pad self does not produce the phenomenon such as eddy current, heating when excess current.
durable in use:
Corrosivity and the working life of mechanical property, acidproof alkali salt are all better than spring steel pad.Be designed to cone table ring-type disc, uniform load is distributed in top surface edge and lower surface edge.Can in case quiet will load, non-alternating load or dynamic loads, can meet the requirement that strict fatigue life and power carry loss.
more than show and describe basic principle of the present utility model, major character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
