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, 抗干扰能力强. 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, 稳定性好, 高灵敏度, miniaturization, light weight, 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. 最后, it may even catch fire, causing accidents, and even serious accidents such as breakdown and explosion. 长时间, due to the high potential environment of the main circuit of high-voltage switchgear (mainly referring to the contact arms, 接触, 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
荧光光纤测温属于接触式测温方法. 该设备根据荧光余辉寿命的长度实现温度测量. 施加在远程测温端的荧光物质在受到特定波长的光的刺激时,会发出相应的荧光能量. 去除特定波长光的激发后, 荧光余辉开始衰减. 荧光余辉的持续时间取决于温度测量探头上荧光物质的温度, 那是, 待测物质的温度. 特定波长光激发的选择与所选的荧光物质相匹配, 并且不同荧光物质最有效的激发波长不同.

 

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. The fluorescent fiber optic temperature sensor is connected to the temperature controller to achieve the purpose of monitoring the temperature of the switchgear busbar.
