Many power distribution industries in the power system are prone to safety accidents in hot weather or long-term operation, which are mostly caused by the heating of the connection points in the cabinet. ထို့ကြောင့်, in order to avoid and reduce accidents, it is mainly necessary to know the temperature changes and values of the contacts in advance. သို့သော်, existing temperature measurement methods, whether active wired non-contact or passive wired contact, have one or another problems, such as interference from the surrounding environment and electromagnetic fields, large volume, vulnerability, complex installation, difficult maintenance, inability to withstand high temperatures, poor insulation performance, easy false alarms under high temperatures, large temperature differences from the actual temperature values, battery replacement, short lifespan, and so on.

Cable joints are a key component of cable power transmission, and the process of cable joints includes various factors such as insulation materials, stress control and crimping quality, as well as sealing and heat dissipation. Easy to cause problems, resulting in a high failure rate of cable heads. According to statistics, cable head failures account for over 80% of cable operation failures.

Why do cable joints need temperature measurement

In recent years, with the growth of the economy, the demand for electricity has gradually increased, and the power system has also developed towards large capacity, မြင့်မားသောဗို့အား, and intelligence. The safe and efficient operation of the power system is closely related to the healthy development of the economy and the stability of people’s lives. The high-voltage cables in China’s power system have the characteristics of high voltage and high current. Splices are generally used to connect them at the T-junction of users, the overlap between the high-voltage pile head of column switches and cables, and the overlap between the high-voltage pile head of transformers and cables. After a period of use, the joint may overheat due to metal fatigue, deformation, and other issues, which can cause power failures. ထို့ကြောင့်, the power department needs to monitor the temperature situation at the joints of each high-voltage cable in real time to avoid overheating of the joints and causing power failures, ensuring the normal operation of power supply. The safety accidents in the distribution industry of China’s power system are mostly caused by the heating of the connection points in the cabinet. ထို့ကြောင့်, in order to avoid and reduce the occurrence of accidents, it is mainly necessary to know the temperature changes and values of the contacts in advance.

After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole through cable joints. သို့သော်, due to the skin effect of charges, eddy current loss, and insulation medium loss, additional heat is generated, which causes the temperature of the cable to rise. When the load current of the cable is too large, the temperature of the cable joint will rise sharply, causing the core wire to heat up and causing a fire; ဖြည့်စွက်ကာ, there are gaps at the cable joints, which can allow rainwater to seep in and cause the cable joints to become damp, leading to accidents. The power cable joint operates under high voltage (35kV and below) and high current (630A and below) conditions. During operation, heating can have an impact on the system operation. In order to monitor the temperature at the middle joint of the cable, the traditional temperature measurement method currently used is to manually measure the temperature at the cable joint using an infrared thermometer, which increases the workload of the staff and cannot continuously measure the temperature. It is difficult to timely understand the situation when accidents occur. The problem with the detection method of the infrared online temperature monitor is that it can only be randomly monitored, and monitoring is greatly affected by environmental factors such as high temperature, မြင့်မားသောဗို့အား, high electric field, စသည်တို့. ထို့ကြောင့်, real-time monitoring of the temperature at the cable joint cannot be carried out, which can easily lead to accidents. Both active wired non-contact and passive wired contact types have various problems, such as interference from the surrounding environment and electromagnetic fields, large volume, susceptibility to damage and breakage, complex installation, difficult maintenance, high temperature resistance, poor insulation performance, susceptibility to false alarms at high temperatures, significant temperature differences from actual temperature values, battery replacement, short lifespan, and so on.

The FJINNO cable joint fiber optic online temperature measurement system is the latest fiber optic temperature measurement technology developed using advanced fluorescence fiber optic temperature measurement principles. The fiber optic temperature measurement sensor has accurate temperature measurement accuracy, လျင်မြန်သောတုံ့ပြန်မှုမြန်နှုန်း, stable operation, and is widely used in the power cable industry. The price is reasonable, and we welcome agency cooperation.
