Which temperature monitoring system is the best for the high-voltage electrical equipment busbar to use

Temperature monitoring system for electrical equipment

Online temperature monitoring system for high-voltage electrical equipment busbar
The temperature monitoring system of electrical equipment must have good insulation, high accuracy, fast response ability, and strong anti-interference ability. Compared to traditional temperature measurement methods such as infrared thermometers for switchgear, the disadvantage is poor temperature stability and susceptibility to vibration and magnetic field effects.

Fluorescent fiber optic temperature sensors have obvious advantages such as resistance to electromagnetic interference, good stability, 고감도, miniaturization, 경량, and contact temperature measurement. fluorescent fiber optic temperature sensors for online monitoring of electrical equipment.

The necessity of installing a temperature monitoring system for high-voltage switchgear
During the long-term operation of switchgear, the high-voltage switch contacts, busbar overlap points, and other parts in the switchgear often have excessive contact resistance due to improper installation or aging, resulting in abnormal temperature in the main circuit. If this change is not known in a timely manner and continues to operate, it will further intensify heating and oxidation, and create a vicious cycle, leading to phenomena such as melting and falling off of the contact finger, burning of the contact head, and deterioration of adjacent insulation materials. 마침내, it may even catch fire, causing accidents, and even serious accidents such as breakdown and explosion. 오랫동안, due to the high potential environment of the main circuit of high-voltage switchgear (mainly referring to the contact arms, 연락처, and busbars), various problems such as high-voltage insulation and electrical isolation under high and low potential cannot be solved under direct measurement conditions, making online monitoring of circuit breaker temperature a difficult problem.

Temperature measurement principle of fluorescent fiber optic switchgear
형광섬유 온도 측정은 접촉식 온도 측정 방법에 속합니다.. 이 장치는 형광 잔광 수명에 따라 온도를 측정합니다. 원격 온도 측정 끝에 적용된 형광 물질은 특정 파장의 빛에 의해 자극될 때 해당 형광 에너지를 방출합니다. 특정 파장의 빛의 여기(excitation)를 제거한 후, 형광 잔광이 사라지기 시작합니다. 형광 잔광의 지속 시간은 온도 측정 프로브에 있는 형광 물질의 온도에 따라 다릅니다, 말하자면, 측정할 물질의 온도. 특정 파장의 light excitation의 선택은 선택한 형광 물질과 일치합니다., 그리고 다른 형광 물질의 가장 효과적인 여기 파장은 다릅니다.

Characteristics of online monitoring system for temperature of high-voltage switchgear busbar
(1) The fiber optic temperature measurement device of the busbar must have strong resistance to strong electromagnetic interference inside the switchgear;

(2) The fiber optic temperature measurement system must have a sufficiently short reaction time, which determines that the hardware and software used in the system design must have a relatively fast operating speed;

(3) During the online monitoring of the switchgear, it is necessary to maintain the normal operation and performance of the switchgear.

The online monitoring system for fluorescent fiber optic temperature measurement of switchgear, the high-voltage busbar contact temperature measurement system, and the busbar contact components are equipped with temperature sensors. 이 형광성 광섬유 온도 감지기 is connected to the temperature controller to achieve the purpose of monitoring the temperature of the switchgear busbar.
