این fluorescence fiber optic temperature measurement system has a simple structure, is easy to use, provides more accurate temperature measurement, and reduces temperature measurement deviation. It can measure temperature of cables, cable joints, plugs, insulation plugs, fiber optic cables, شینه ها, مخاطبین, خطوط ورودی و خروجی, pile heads, transformers, و موارد دیگر.
Cable plugs, as a type of connection point for electrical equipment, often suffer from high temperature burnout due to poor conductor contact. Due to the high voltage carried by the internal conductor of the cable plug, the usual thermocouple temperature measurement method is obviously not applicable. در حال حاضر, the main temperature measurement method for cable plugs and sockets is to install wireless sensors on their surfaces for surface temperature measurement, in order to infer the temperature of their internal conductors. The weakness of this technology is that it cannot accurately measure the actual temperature of the conductors inside the cable plug. When abnormal temperature is detected, the inside of the cable plug is often damaged, which has a huge impact on ensuring power transmission. It can directly monitor the temperature of the internal conductor of the cable plug, which is convenient to use, safe and reliable, ensuring stable power transmission and reducing losses caused by this reason. The advantages are simple structure, easy operation, superior performance, and safety and reliability. Insulation plugs that can be used to replace various types of cable plugs.
There are a large number of electrical equipment in the power system, which can cause abnormal heating due to manufacturing processes, contact oxidation, and arc impact, laying hidden dangers for the safe operation of the equipment. If the abnormal heating of the equipment is not detected in a timely manner, it can easily lead to equipment damage or even combustion and explosion, causing a large amount of property damage.
بنابراین, temperature detection of various electrical equipment, such as cables, is highly valued in power system monitoring. در حال حاضر, the temperature detection of cable heads mainly involves attaching temperature sensors to the outer surface of the cable head for temperature detection. اما, the sensors currently used are mainly powered by batteries, which pose certain safety hazards in high-temperature environments. Replacing batteries also brings high maintenance costs, and because temperature measurement is carried out on the outer surface of the cable head, it is not possible to directly measure the temperature inside the cable casing, resulting in certain errors. This has led to safety hazards, high maintenance costs, and significant errors when using active temperature measurement for current cable head temperature measurement. When using passive temperature measurement, calibration is required in different working environments, and there are also technical issues with significant errors. The application of wireless passive sensors for online monitoring of cable joints is mainly achieved by installing wireless passive temperature sensors inside the plugs of the cable joints, which are usually fixed on the PCB board and indirectly transfer heat to the wireless passive temperature sensors through other connectors. The heat is prone to deviation during the indirect conduction process, which affects the accuracy of temperature measurement.
FJINNO’s independently developed plug fluorescent fiber temperature measurement device adopts the latest technology of fluorescent fiber temperature sensor. The fluorescent fiber probe can directly obtain the true temperature of the plug and provide it directly to power equipment manufacturers through the device. It is insulated and anti-interference, and the price is reasonable. Welcome to cooperate with agents!
