Embodiment Construction

[0024] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0025] This embodiment provides a cable heat dissipation device with an overheating alarm function, which is mainly installed on the power cable with heavy load and long-term operation, and is used to effectively dissipate heat from the cable itself and monitor the actual heat dissipation effect on site. The device is recommended to be installed at both ends of the cable The end is close to the equipment, because most of the heat generated by the cable is concentrated in this position.

[0026] Such as Figure 1 to Figure 3 As shown, a cable heat dissipation device with an overheating alarm function provided in this embodiment includes a clamp 2 fixed to the outer skin of the three-core thick cable 1. The clamp 2 is made of a material with good heat di...

Abstract

The invention relates to the technical field of heat diffusion of cables, and discloses a cable cooling device with an overheat alarming function, which comprises a hoop sleeving and fixed on the outer skin of the cable in a surrounding mode. Hoop assemblies are joined through connection bolts to form the hoop; cooling fins are arranged outside at least one hoop assembly and a cooler bracket is connected; the inner space of the cooler bracket is provided with cooling fans; the cooling fans comprise an air suction fan and an air supply fan arranged at two ends of the cooler bracket respectively; the cooler bracket body is internally provided with a power supply mounting groove and a temperature monitoring module mounting groove, a power supply and a temperature monitoring module are mounted respectively, the temperature monitoring module is connected with the cooling fan and a sound-light alarm through wires, and the cooling fans and the sound-light alarm are started respectively according to detected temperature conditions. The device of the invention is designed specially for the cable, overheat aging of the cable can be slowed down effectively through cooling the cable, and the cable and the connection device can be prevented from being burnt down timely through the sound-light alarming.

Description

technical field [0001] The invention relates to the technical field of thermal diffusion of cables, in particular to a cable heat dissipation device that can be directly installed outside the cable. Background technique [0002] Cables are responsible for data, signal voltage, and current transmission in engineering projects. Cable life indicators directly determine the reliability of equipment systems, and more than 80% of cable failures are caused by heat. Thermal aging is a key factor in insulation processing and Evaluable. At present, most of the equipment bodies are equipped with cooling devices, but the cables do not have related heat dissipation and overheating alarm devices, which often lead to serious overheating and aging of cables, and eventually lead to the burning of cables and connecting equipment, resulting in huge property losses and personnel safety issues. Contents of the invention [0003] The invention aims to solve the technical problem of cable over...
