Problems solved by technology

[0002] At present, in the power industry, there are many kinds of temperature limit indicators, but these temperature limit indicators have great potential safety hazards, and now the market Most of the ones used on the Internet are in the form of tightened nuts. When this type of temperature limit indicator is installed, the hand is in contact with the nut for too long, which is very dangerous for high-voltage lines.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, the color-changing temperature display sheet 2 is placed in the cavity formed by the shell 1 and the transparent plastic shell 3. The transparent plastic shell 3 wraps the shell 1 and the transparent plastic shell 3 is transparent as a whole, and the staff can see the inside from a distance. The color-changing temperature display sheet 2, the thermal ferrite 6 is fixed on the fixed display body 7, and the thermal ferrite 6 is very sensitive to the change of temperature. At normal temperature, the thermal ferrite 6 and the magnet 4 are attracted together Together, a spring 5 is arranged between the two. When the temperature was too high, the magnetic permeability of the thermosensitive ferrite 6 would drop and break away from the magnet 4; Fix the protruding rods corresponding to the four concave holes on the display b...

Abstract

The invention relates to a lead joint radiation monitoring nut which is convenient to install and disassemble and has high safety. The lead joint radiation monitoring nut comprises a shell, a fixed display body and a movable display body are arranged in the shell and are buckled; the top of a specified display body is provided with heat sensitive ferrite; a spring is arranged between the heat sensitive ferrite and the magnet of the inner top wall of the shell; and the outer part of the shell is successively provided with a discoloration temperature display sheet and a transparent plastic shell.

Description

technical field [0001] The invention relates to a heating monitoring nut at the connection part of a wire. Background technique [0002] At present, in the power industry, there are many kinds of temperature over-limit indicators, but these temperature over-limit indicators all have great potential safety hazards. Most of the indicators used in the market are in the form of tightened nuts. When this kind of temperature limit indicator is installed, the hand is in contact with the nut for too long, which is very dangerous for high-voltage lines. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provide a heating monitoring nut at the connection of wires, the temperature limit indicator is directly buckled at the connection part during installation. [0004] The technical scheme that the present invention solves technical problem is taken: [0005] A heat monitoring nut at the connection of wires, which includes a c...
