Temperature measurement system for high-voltage power equipment conductors

With the development of the economy and the increasing demand for quality of life, the demand for electricity is increasing, and the quality requirements for power supply provided by the power supply department are also higher. Por lo tanto, the stable operation of the power grid for long-distance transmission lines is very important. Wire temperature is an important parameter for the operation of transmission and distribution lines. Real time monitoring of wire temperature can improve the current carrying capacity of wires, provide key data for the dynamic capacity increase of wires, and effectively improve the transmission capacity of existing transmission lines.

The current general rural power grid comprehensive distribution cabinets are mainly used for rural and suburban agricultural distribution networks. It is difficult to solve some of the problems of low power quality in agricultural distribution networks, such as long power supply radius, high line loss rate, and large voltage drop of some distribution lines, especially in remote mountainous areas. The normal and safe operation of high-voltage electrical cabinets has become particularly important. Sin embargo, due to the fact that many places are far away, especially in high temperature and sun exposure in summer, and the operation of high-voltage electrical cabinets generates a large amount of heat, which was previously sealed with iron high-voltage electrical cabinets. This leads to the accumulation of a large amount of heat inside the electrical cabinets, causing different degrees of damage to internal components, and in severe cases, burning out, resulting in a large amount of heat. Affects normal use, increases maintenance difficulty, and increases operation and maintenance costs. High voltage insulation sleeve is the core component of power transmission engineering. The reliability of the operation of high voltage insulation sleeve is related to the safety of the entire DC system. If a fault occurs during operation, it can cause damage to the main body of the high voltage insulation sleeve, and in severe cases, it may cause explosion of the high voltage insulation sleeve, leading to serious burning of the transformer, and even damage to the valve hall of the converter station. Al mismo tiempo, it can cause the DC system to lock, leading to large-scale power outages and huge economic losses. Por lo tanto, ensuring the operational reliability of high-voltage insulation sleeves is crucial. Sin embargo, the temperature inside the high-voltage insulation sleeve is an important factor affecting its operational reliability. Por lo tanto, it is necessary to monitor the temperature inside the high-voltage insulation sleeve so that on-site operators can take corresponding measures based on this temperature situation to ensure the stable operation of the high-voltage insulation sleeve.

The reliability of power supply is directly related to the safety of the operation of the rail transit system. If the power supply equipment malfunctions, it often leads to the suspension of rail transit and even safety accidents. This not only causes huge economic losses, but also may endanger the personal safety of passengers, causing extremely adverse social impacts. The rail transit line is long, there are many power supply equipment, and there are many inspection points. The traditional dedicated person on duty inspection method is difficult to meet the maintenance needs of the equipment.
