Abstract
The utility model relates to a nut for instantly monitoring heating of a wire connecting part, which comprises a housing, an indicating rod, a fixed bolt, carbon fiber stuffing, a permanent magnet, a heat-sensitive ferrite and a spring, wherein the indicating rod and the spring are arranged in a cavity of the housing; one end of the spring is connected with the permanent magnet; the housing is clamped at the wire connecting part through a clamp switch; the indicating rod is clamped in the cavity through a bimetallic strip; the heat-sensitive ferrite is fixed at one side of the indicating rod close to the wall of the cavity; one end of the heat-sensitive ferrite is fixedly connected with the spring; and the lower part of the housing is provided with the fixed bolt and the carbon fiber stuffing. During installation, the nut is fixed on a bolt at the connecting part through the fixed bolt by an operator, and the nut can be taken down by through the rotating of the fixed bolt, so that the installation process is more convenient and faster, and the safety performance is higher.
Description
Technical field
The utility model relates to the out-of-limit indicator of a kind of lead joint temperature, specifically a kind of instant lead joint heating monitoring nut.
Background technique
At present in power industry, have the many kinds of out-of-limit indicators of temperature, but all there is very big potential safety hazard, making the land used major part now all is the nut form of tightening, but tightening nuts form ground is the overlong time that hand contacts with nut in installation, there is very big danger in this in ultra-high-tension power transmission line, and can only use with supporting bolt matching, and Applicable scope is very little.
The model utility content
The purpose of this utility model is to address the above problem, and heating monitoring nut in a kind of instant lead joint is provided, and the out-of-limit indicator of this temperature is placed on nut on the bolt and by fixing bolt when mounted and tightens; Owing to have fixing bolt, make the Applicable scope of nut become big.
The technical scheme in the invention for solving the technical problem is:
A kind of instant lead joint heating monitoring nut, comprise shell, indicating arm, fixing bolt, filled with carbon fibers thing, permanent magnet, heat sensitive ferrite and spring, described indicating arm and spring are arranged in the cavity of shell, spring one termination has permanent magnet, shell is stuck in the lead joint by the screens switch, indicating arm is stuck in the cavity by bimetallic strip, and indicating arm is fixed with heat sensitive ferrite in the side near internal chamber wall, and heat sensitive ferrite one end and spring are fixed; Be provided with fixing bolt and filled with carbon fibers thing in lower housing portion.
The beneficial effects of the utility model are: be fixed on by fixing bolt on the bolt of joint by the staff during installation, can rotate fixing bolt during unloading nut is taken off, this just makes the installation process more convenient and quicker, and Security is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 shell, 2 indicating arms, 3 springs, 4 permanent magnets, 5 heat sensitive ferrites, 6 fixing bolts, 7 filled with carbon fibers things.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, heating monitoring nut in a kind of instant lead joint comprises shell 1, indicating arm 2, spring 3, permanent magnet 4, heat sensitive ferrite 5, fixing bolt 6 and filled with carbon fibers thing 7.
Installation personnel places nut on the bolt of installation position when installing, and fills with filled with carbon fibers thing 7 by the space between fixing bolt 6 fixing thems.Described indicating arm 2 is to be placed in the cavity of shell 1 formation, one end is indicating arm 2 outlets, one end is fixed with heat sensitive ferrite 5, the other end of heat sensitive ferrite 5 and spring 3 are affixed, spring 3 the other ends are connected on the permanent magnet 4 that is built in cavity, the permeability of heat sensitive ferrite 5 changes 60,70,80 degrees centigrade are not waited, can select different heat sensitive ferrites to adapt to different line temperature more, permanent magnet 4 attracts indicating arms 2 and pressure springs 3 when not surpassing more the line temperature, make in the indicating arm 2 indentation cavitys, when temperature surpasses qualification, the permeability of heat sensitive ferrite 5 changes, indicating arm 2 is ejected by spring 3, and scribbling eye-catching color on the indicating arm 2 can remind the inspector to find danger timely.
