Abstract

The invention discloses an excess temperature attention device for plate-shaped equipment. The device comprises a threaded rod, a metal pressing block fixed at the top end of the threaded rod, a temperature sensing pressing plate and an outer box; the threaded rod penetrates through the center of the bottom of the temperature sensing pressing plate, and is connected / contact with the temperature sensing pressing plate; the top of the temperature sensing pressing plate and the bottom of the outer box are integratedly connected; the outer box comprises a temperature sensing glass ball, a box cover, a pull rod, a pressure spring and an attention belt; the outer box is a shape of a cylinder with a top end provided with an opening and a sealed bottom; the box cover covers the opening at the topend of the outer box, and is fixedly connected with the temperature sensing glass ball through a pull rod hole at the lower portion of the pull rod; the pressure spring is arranged in the outer box,both ends of the pressure spring are respectively connected / contact with the box cover and the bottom end of the outer box; and the two ends of the attention belt are respectively connected with thebox cover and the inner wall of the outer box. The excess temperature attention device can achieve the function of excess temperature attention, the equipment is not affected, the potential safety hazards are eliminated, and the applicability is strong.

Description

technical field [0001] The invention relates to the technical field of temperature monitoring, in particular to an over-temperature warning device for plate-type equipment. Background technique [0002] In the actual operation of power lines, due to loose bolts at the joints of connecting fittings, dirty contact surfaces, poor lead sealing of cable tail pipes, electrochemical corrosion of copper and aluminum, etc., the resistance is likely to increase. , It is very easy to cause the local temperature to be too high and cause various failures. However, the faults caused by connecting fittings are often not self-recoverable, requiring a lot of manpower and material resources for emergency repairs, which has a great impact on the power grid and society. [0003] Therefore, it is extremely necessary to carry out regular maintenance and monitoring on the connection fittings of the power line. The current main method is to conduct regular infrared temperature measurement on the c...
