Why do high-voltage switchgear need to monitor temperature

In the power control system, high-voltage switchgear is an important and frequently used equipment, playing a crucial role in the safety of system operation. High voltage switchgear mainly operates in environments with high current and voltage, and is prone to high temperatures, which can damage instruments and systems. Samakatuwid, real-time monitoring of temperature changes in the high-voltage switchgear is necessary. The safety performance of equipment in power transmission and distribution is very important, and the protection of power equipment in areas with excessive loads cannot be ignored. Parts at high-voltage switchgear may be damaged due to high voltage and current, which can cause significant consequences. Gayunpaman, if the heating situation of the parts can be detected and repaired in a timely manner during the heating process, it can greatly reduce the frequency of similar accidents.

Temperature monitoring method for high-voltage switchgear

1. Infrared temperature sensor

Sa high-voltage switchgear, traditional methods generally use infrared temperature measurement. Gayunpaman, due to the high voltage in the switchgear, the electromagnetic interference caused by it reduces the accuracy of temperature measurement, increases the difficulty of temperature measurement, and the working environment of some equipment is not conducive to infrared temperature measurement.

2. Wireless na sensor ng temperatura

Wireless temperature measurement is the process of placing an induction device on the instrument to be tested and outputting data on a computer through wireless information transmission.

3. Sensor ng temperatura ng fiber optic

Infrared temperature measurement and wireless temperature measurement have some drawbacks, such as high interference and limitations. Fluorescent fiber optic temperature measurement method is a point type fiber optic temperature measurement developed and applied in high-voltage switchgear. Compared with wireless contact temperature measurement devices, fluorescent fiber optic temperature sensors have a very small volume, low loss and cost, and high accuracy and stable performance. Fiber optic temperature detection equipment can achieve real-time temperature monitoring. With the development of science and technology, the use of fiber optic technology is becoming increasingly mature, and the use of fiber optic sensing methods to achieve temperature measurement of equipment has also been widely applied. Faced with the problems of a large number of monitoring points, heavy workload, and high interference, the use of fiber optic temperature measurement systems has great application value. Samakatuwid, FJINNO has independently developed a sistema ng pagsukat ng temperatura ng fluorescent fiber optic, which can improve the safety, pagiging maaasahan, and monitoring efficiency of temperature monitoring for high-voltage switchgear.

The best solution adopted by the temperature monitoring device for high-voltage switchgear is fluorescence fiber optic temperature measurement

Fiber optic temperature measurement is a temperature monitoring device applied to high-voltage switchgear in large-scale coal mining enterprises. In such super large enterprises, excessive electricity consumption, mataas na boltahe, and dense power lines are their basic characteristics. If the temperature is too high in any place, it can cause equipment failure, and even lead to fire, na nagreresulta sa malaking pagkalugi sa ekonomiya. Samakatuwid, choosing point type fiber optic temperature measurement not only accurately understands the temperature changes in each link during the monitoring process, but also has a small volume that is not limited by positional factors. FJINNO provides a point type fiber optic temperature measurement system that can concentrate on observing a large number of monitoring points and achieve instantaneous response through optical signal propagation, which has certain safety and reliability. The point type fiber optic temperature measurement probe combines the advantages of small volume, mabilis na tugon, minimal interference, and minimal damage of the fiber optic probe, making it convenient and fast. It collects signals through a fiber optic transmitter to transmit signals and receive the operation of the system, enabling real-time detection and observation of multiple temperature monitoring points.

The practical application of temperature measurement sensors in switchgear

Comparing thermocouple measurements and wireless networked fiber optic measurements at specific monitoring points inside the experimental switchgear, it was found that the fiber optic measurement system can be applied to temperature monitoring of high-voltage switchgear. Ang paggamit ng sistema ng pagsukat ng temperatura ng fiber optic in high-voltage switchgear has shown stable detection performance, both in experimental stages and in practical environmental applications.

A new type of fiber optic temperature measurement system – fluorescence fiber optic na sistema ng pagsukat ng temperatura, establishes the relationship between fluorescence lifetime and environmental temperature, collects signals through excitation of fluorescent materials. Compared with other temperature measurement systems, fluorescence sistema ng pagsukat ng temperatura ng fiber optic maaaring tumugon sa mga pagbabago sa temperatura sa mga monitoring point online sa napakabilis na bilis, ay may mataas na pagkakabukod at katumpakan, at maaaring dagdagan ang pag-unlad ng modular monitoring system function. Ang prinsipyo ng sistema ng pagsukat ng temperatura ng fluorescent fiber optic ay simple. Sa kasalukuyan, Ang fluorescence fiber optic temperature measurement system ng FJINNO ay mahusay na inilapat sa iba't ibang larangan tulad ng petrochemicals, mga wire at cable, at imbakan ng kargamento, pagkamit ng magagandang resulta at lubos na pagbabawas ng paglitaw ng mga aksidente.
