Description

Technical Field

[0001] The utility model belongs to the technical field related to cable temperature control monitoring, and specifically relates to a temperature control monitoring and protection device for electric wires and cables. Background Art

[0002] Electricity is an energy source that uses electrical energy as a driving force. It is an electricity production and consumption system composed of power generation, transmission, transformation, distribution and power consumption. It converts primary energy in nature into electricity through mechanical energy devices, and then supplies electricity to various users through transmission, transformation and distribution. Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation. It is one of the main components of modern power transmission lines. The existing technology is limited by the cable installation height and cannot detect cables of different diameters. Patent No. CN202122007203.1 discloses a temperature detection device for power cables. The cable temperature is detected by a clamping detection mechanism. It is not limited by the cable height. The adjustment component enables the clamping detection mechanism to detect cables of different diameters, which improves the applicability.
