Problems solved by technology
However, the fire blanket cannot be completely relied on for fire prevention, because the function of the fire blanket means that it has caught fire, and the fire blanket can only be used as the last line of defense for fire prevention. Therefore, the temperature detection of the cable joint is also an important part of preventing cable fire accidents. However, It is not easy to measure the temperature of the cable joint after the cable is wrapped by a fireproof blanket. It is easy to damage the cable joint part when blanketing, which accelerates the damage speed of the cable joint and shortens the service life of the cable joint

Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0018] Such as Figure 1-5 As shown, a temperature-measuring cable joint fireproof blanket includes a rectangular blanket body 1. The inner surface of the blanket body 1 is connected to a heat-conducting telescopic rod 2 extending along the long-side direction near the edge of one side of the long side. The heat-conducting telescopic rod 2 There are a number of elastic heat-conducting sheets 3 that can be curled into an arc shape connected to the top, and the left end of the heat-conducting telescopic rod 2 extends to the outside of the blanket body 1 and is connected with a heat-conducting seat body. A slot 6 is arranged on the heat-conducting seat body, and the slot 6 A heat-conducting rod is inserted, and a circular heat-conducting ball 4 is arranged on the top of the heat-conducting rod. The surface of the heat-conducting ball 4 is coated with a temperature-sensit...

A temperature measurement type cable joint fireproof blanket comprises a rectangular blanket body, a heat conduction telescopic rod extending in the long edge direction is connected to the position, close to the long edge of one side, of the inner surface of the blanket body, a plurality of elastic heat conduction pieces capable of being curled into a circular arc shape are connected to the heat conduction telescopic rod, and the left end of the heat conduction telescopic rod extends out of the blanket body and is connected with a heat conduction base. The top of a heat conduction rod is provided with a circular heat-conducting ball, and the right end of the heat conduction telescopic rod extends out of the blanket body and is connected with a thermoelectric power generation assembly. The blanket has the advantages that the temperature of the cable intermediate joint can be detected without detaching the fireproof blanket, damage to a cable intermediate joint caused by repeated detaching and wrapping of the fireproof blanket is avoided, manpower is saved, the detection is accurate and reliable, the temperature abnormity of the cable intermediate joint can be found in time, fire disasters are avoided, and safety accidents are reduced.
Description
technical field [0001] The invention relates to a temperature-measuring type cable joint fireproof blanket. Background technique [0002] At present, the cable intermediate joint is an important part to connect two cables, and it is also the weakest link in the power line. There may be contact resistance or defects in the middle joint of the cable during the manufacturing or installation process, resulting in a local temperature rise. In addition, the high ampacity in actual operation will also increase the temperature of the joint, accelerate insulation aging, and shorten the cable joint. This poses a threat to the stable transportation of electricity, so monitoring the temperature of the cable joint has strong practical significance. [0003] Usually, a fireproof blanket is wrapped around the cable joint. Once the cable joint catches fire at high temperature, it can play a role in fire prevention and explosion protection and reduce the degree of harm of the accident. How...
