In the practical application of busbar trunking, due to long-term operation in the air and the influence of ambient temperature and humidity, 열팽창과 수축, 표면 스케일링, 산화 또는 부식이 발생할 수 있습니다., leading to loose contacts and poor contact. Especially in some large buildings (대형 공장과 같은, 초고층 빌딩, 등.), where the installation position of busbar trunking cannot be manually monitored, users often neglect the safety management of busbar trunking. Once the temperature of the busbar joints during operation is abnormally overheated, it may lead to fire or major safety and quality accidents, bringing huge and irreparable personal injury and economic and property losses to enterprises.
The bus duct is in a fully enclosed state during operation and is generally in a long-term live state, making daily maintenance and inspection very inconvenient. 그러므로, it is necessary to monitor the temperature of the bus joints inside the bus duct to improve the reliability of its operation.

During the operation of power equipment (such as power switchgear), it is often necessary to confirm the operating status of the equipment by measuring the temperature of various parts and components inside the power equipment. Contact temperature measurement is a commonly used method, but in the contact temperature measurement method, it is difficult to install the temperature measuring device on the busbar to ensure the reliable connection between the temperature sensor and the busbar, and to ensure the reliable measurement of temperature. 예를 들어, it is fixed with aviation specific adhesive, but the assembly efficiency is relatively low, and the contact stability and reliability are poor.

The busbar refers to the connecting conductors between the main switch in the distribution cabinet and each branch circuit in the power supply system. The busbar may experience temperature rise during operation due to various reasons, but the temperature of the busbar needs to be controlled within a certain range to ensure the normal operation of the power supply system and prevent accidents. 그러므로, temperature monitoring of the busbar is necessary at all times.
지속적인 기술의 발전으로, various wireless bus temperature measurement devices have been used in the daily maintenance of busbars, which are basically powered by batteries, solar energy, external power supply, self induction power supply, 등. The device structure is complex.

With the emergence of high-rise buildings and large factories, the electricity consumption in various industries has grown rapidly, and traditional cables can no longer meet the requirements in the transmission of large currents. As a new type of distribution conductor, plug-in bus duct has emerged. Compared with traditional cables, it can fully demonstrate its advantages in high current transmission. 하지만, the busbar trunking is exposed to high current and high voltage working environments for a long time. Due to aging, 산화, loosening and other reasons, the contact resistance of the busbar contact points and each section of the connection will increase, leading to heating of the busbar, causing safety accidents such as leakage and melting, and even causing fires. 그러므로, temperature monitoring of the busbar trunking is particularly important.

현재, there are several main solutions for temperature monitoring of bus ducts:

1. Infrared temperature measurement technology:

The measurement range is large and the accuracy is high, but with cable communication, cables need to be laid and temperature measurement space is required, making it impossible to achieve integrated integration of busbar equipment and online temperature detection. If there is a fault in the line, it will cause temperature measurement failure on a large area of the line.

2. Wireless temperature measurement technology:

Using wireless communication technology for signal transmission, due to distance limitations, it is necessary to set up adapter nodes (repeaters) at a certain distance to amplify the signal; Wireless signals are greatly affected by obstacles and are prone to attenuation; 언제 무선 온도 측정 is used, the service life of the power supply battery needs to be considered, and a time-based circuit (즉. supplying power to the system at intervals) is adopted. Although this method extends the service life of the battery, it cannot achieve the function of real-time data collection, which poses a safety hazard.

3. 분산 광섬유 온도 측정

그만큼 분산 광섬유 temperature measurement system is applied to the busbars and busways of each circuit for real-time temperature monitoring, thereby achieving safety monitoring of the operation of the busbar equipment.

분산 광섬유 온도 측정 시스템: It adopts optoelectronic technology, 통신 기술, 마이크로프로세서 기술, 디지털 온도 감지 기술, and designed low temperature, 강한 전기장, 및 습한 환경 운영 기술. 다양한 환경의 온도를 별도로 모니터링할 수 있습니다., 사고 위험을 조기에 감지, and effectively reduce losses. 동시에, it can also provide a large amount of online monitoring data to provide operators with a comprehensive understanding of the outer temperature of the busbar, thereby indirectly inferring the current and load situation in the busbar, and providing power allocation basis for departments.

The significance of 분산 광섬유 온도 측정 시스템:

1. Safely increasing the current carrying capacity of the circuit;

2. Can achieve periodic state monitoring;

3. Drive external alarms or other emergency systems;

4. Identify hotspots (특히 잠재적인 사고 위험이 있는 버스 연결부) 및 기타 환경 이상.

The distributed fiber optic temperature measurement system is a highly intelligent and automated monitoring technology that does not require manual inspection of the monitored area. The monitoring room screen can display temperature information of various points in the entire monitoring area; 과열점이 있는 경우, it can sound or light an alarm, and even send it to relevant personnel via mobile phone SMS. Can accurately predict hot spots before accidents occur, with high positioning accuracy, and display the evolution of hot spot temperature. 동시에, the temperature sensor in the distributed fiber optic temperature measurement system has the characteristics of explosion-proof, 강한 전자기 간섭 저항, 좋은 전기 절연성, 번개 보호, 높은 정밀도, 가벼운 무게, 작은 볼륨, 내식성, 고온 저항, and no static electricity.
