Wat is een goed temperatuurmeetsysteem voor stroomonderbrekers?

Waarom gebruiken stroomonderbrekers? temperatuurbewakingssystemen

De ontwikkeling van de stroomkabelindustrie gaat zeer snel, en veel distributiestationbesturingssystemen zijn begonnen met industriële automatisering, monitoring en monitoring systeemcommunicatie digitalisering, waardoor het onderhoud en gebruik van stroomvoorzieningsapparatuur veiliger wordt; The circuit breakers in the switchgear are commonly used during operation, which can easily lead to wear on the dynamic and static contacts of the circuit breakers, loose fasteners on the terminal busbar, and other phenomena; If the circuit breaker is not subjected to temperature monitoring, it is possible to generate high temperature heat, which can cause aging of the insulation components of the switchgear and potentially lead to fire or damage to power equipment.

FJINNO's fluorescerende glasvezeltemperatuurmeetsysteem voor stroomonderbrekers in schakelapparatuur bewaakt en regelt effectief de temperatuur van de stroomonderbrekers, waardoor het voor personeel ter plaatse gemakkelijk is om de verdeelkast te onderhouden. Het terugdringen van gebruikersverliezen en het verbeteren van het productonderhoud en de levensduur hebben goede economische voordelen opgeleverd.

The temperature operation monitoring of high-voltage switchgear is an important way to ensure the safe operation of the power system. Echter, traditional circuit breaker monitors only monitor the electrical parameters (spanning, huidig, and power) in real time. Echter, due to the limitations of high voltage, measurement point positions, and strong electric field interference, the contact temperature is not monitored in real time online by general monitoring equipment.

Tegenwoordig, switch cabinets are all small car type, because the circuit breaker and switch cabinet are connected by plugs. Poor manufacturing, vervoer, and installation of the small car and switch cabinet can cause poor contact and increased contact resistance, resulting in high contact temperature rise or even burning, and power outage. These temperature rise phenomena are particularly prominent in high current switch cabinets such as incoming cabinets, which have a significant impact on the circuit breaker. The connection between the high-voltage switch contact and busbar is always in high voltage, hoge temperatuur, high magnetic field, and extremely strong electromagnetic interference environments. Traditional temperature measuring instruments such as thermocouples and infrared thermometers are easily affected by these factors, making it difficult to accurately measure these positions and thus unable to truly obtain the high voltage switch cabinet. The actual temperature value, resulting in local overheating inside the equipment but still operating at high load, De glasvezel temperatuurmeting device for monitoring the temperature of the contact arm of the circuit breaker can monitor the temperature of the contact arm of the circuit breaker online and detect thermal faults in the circuit breaker contact arm as soon as possible.

The temperature measurement methods for circuit breakers include infrared temperature measurement, thermische weerstand temperatuurmeting, en glasvezeltemperatuurmeting. Infrared temperature measurement is a direct measurement of an object’s surface by manually holding an infrared gun, which is easily affected by environmental temperature. Its biggest disadvantage is that it must be operated manually and cannot achieve online monitoring. Thermal resistors and thermocouples both require metal wires to transmit signals, which cannot solve insulation problems.

The fiber optic temperature detector for circuit breakers can monitor the temperature measurement of high voltage and high current electrical appliances. Bijvoorbeeld, for the temperature detection of the contact of 6-35kV vacuum circuit breakers, fluorescence fiber optic thermometers are mostly used. The fluorescence fiber optic thermometers consist of transmission fibers, glasvezel temperatuursensoren, glasvezel temperatuurzenders, LCD display screens, en andere componenten.
