Abstract
The invention relates to a color-change thermochromic screw comprising a screw body, wherein the upper surface of a screw cap of the screw is coated by a layer of thermochromic coating, the thermochromic coating can be a single-color-change irreversible thermochromic coating or a multi-color-change irreversible thermochromic coating, the initial temperature-change temperature of the single-color-change irreversible thermochromic coating is 60+/-5 DEG C, the initial temperature-change temperature of the multi-color-change irreversible thermochromic coating is 60+/-5 DEG C, and the color-change temperature ranges from 60+/-5 DEG C to 300+/-5 DEG C. By using the color-change thermochromic screw disclosed by the invention, defects of the traditional thermochromic method are made up, overheating parts of circuit connectors are clear at a glance and can be accurately located, and rapid finding and treatment of overheating faults of high/low-voltage circuit connectors can be conveniently realized; and the color-change thermochromic screw can be widely applied to fields such as electric power, machinery, traffics and electronics.
Description
Technical field
The invention belongs to electrical equipment technical field, especially relate to a kind of colour changing thermal indicutor screw.
Background technology
In electrical network, conductor tab refers between electric installation and electrical connection position between electric installation and bus or cable. Along with the swift and violent growth of electric power load in recent years, original electricity supply and use equipment does not carry out upgrading transformation in time and strengthening maintenance, conductor tab superheating phenomenon is caused to happen occasionally, seriously have impact on the safe operation of the power supply reliability of equipment and electrical network, Timeliness coverage is also eliminated accident potential and is seemed especially important. Find that conductor tab is overheated, often adopt in the past and stick temperature display wax sheet or temperature indicating patch at conductor tab place, utilize the methods such as far infrared diagnostic techniques judgement. These methods are while playing a great role; also there is respective limitation; such as temperature display wax sheet or temperature indicating patch are in some cases, it is higher that the conductor joint heating of such as relay protection circuit, measurement loop etc. is limit because of space to use, viewing window is arranged requirement by far infrared diagnostic techniques. Current monotropic look irreversible temperature indicating paint and color variable irreversible temperature indicating paint are released, and progressively promote in all trades and professions, utilize the favourable condition that current new technologies and materials continues to bring out for this reason, and the temp measuring method that research and development make new advances is very necessary.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of colour changing thermal indicutor screw.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of colour changing thermal indicutor screw, comprises screw body, and the screwed cap upper surface at screw is coated with and shows temperature allochroic paint with one layer.
And, described in show temperature allochroic paint be specially monotropic look irreversible temperature indicating paint, the change temperature starting temperature of monotropic look irreversible temperature indicating paint is 60 ± 5C °.
And, described in show temperature allochroic paint specifically adopt color variable irreversible temperature indicating paint, the change temperature starting temperature of color variable irreversible temperature indicating paint is 60 ± 5C °, and the temperature range of variable color is between 60 ± 5C ° to 300 ± 5C °.
Advantage and the positively effect of the present invention be:
The colour changing thermal indicutor screw of the present invention compensate for the deficiency that tradition shows temperature method, very clear, the accurate positioning to circuit joint hot spot, quick discovery and the process being convenient to the high and low pressure overheated fault of circuit joint, can be widely used in the fields such as electric power, machinery, traffic, electronics.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described, it is emphasized that following enforcement mode is explanation property, instead of limited, can not in this embodiment as limitation of the invention.
A kind of colour changing thermal indicutor screw, as shown in Figure 1, comprises screw body 2, and the screwed cap upper surface at screw is coated with and shows temperature allochroic paint with one layer,
In specific embodiment of the invention, described in show temperature allochroic paint be specially monotropic look irreversible temperature indicating paint, the change temperature starting temperature of monotropic look irreversible temperature indicating paint is 60 ± 5C °.
In specific embodiment of the invention, described in show temperature allochroic paint specifically adopt color variable irreversible temperature indicating paint, the change temperature starting temperature of color variable irreversible temperature indicating paint is 60 ± 5C °, and the temperature range of variable color is at 60 ± 5C ° to 300 ± 5C °.
