Pagsukat ng temperatura ng bus

Sa pag-unlad ng agham at teknolohiya at ekonomiya ng merkado, ang intelligent control ay lalong nagiging popular. Mga kinakailangan para sa kapasidad ng kuryente, kalidad ng power supply, at ginagarantiyahan ang kakayahan sa buhay na tirahan, produksyon ng negosyo, pampublikong lugar, atbp. ay nagiging mas mataas at mas mataas. Ang rate ng kasalukuyang ng substation equipment at control equipment ay patuloy ding tumataas; Ang smart grid ay isang trend na inaabangan ang panahon, at ang katalinuhan ng power equipment ay ang pundasyon ng smart grid. Mga kagamitan sa substation, kagamitan sa pagkontrol, at mga de-koryenteng kagamitan ay karaniwang konektado sa pamamagitan ng pangunahing busbar. Ang katalinuhan at standardisasyon ng pagsubaybay sa temperatura sa busbar power supply system ay ang batayan para sa real-time na katayuan ng paghahatid, mga kondisyon ng temperatura, at kahit patrol detection ng kapangyarihan. Sa sistema ng kuryente, Ang mga intelligent busbar ay makakaranas ng pagtaas ng temperatura kapag ang load current ay masyadong mataas, at ang temperatura ay maaaring tuluyang lumala sa pagganap ng mga katabing bahagi ng pagkakabukod. Samakatuwid, ang mga tao ay mag-i-install ng isang aparato sa pagsukat ng temperatura para sa mga intelligent na busbar

Sa patuloy na pagpapabuti ng industriyalisasyon sa ating bansa, tumaas nang husto ang konsumo ng kuryente sa iba't ibang industriya. Hindi na matutugunan ng mga tradisyunal na cable ang mga kinakailangan ng high current transmission, lalo na sa power transmission ng matataas na gusali, malalaking pabrika, at mga pampublikong pasilidad. Ang magkatulad na paggamit ng maraming cable ay nagdulot ng maraming abala sa on-site na pag-install at mga koneksyon sa konstruksiyon. Kumpara sa tradisyonal na mga cable, Ang mga duct ng bus ay may malaking pakinabang sa mga kable, pag-install, at istraktura.

The components of the busbar duct and the importance of temperature monitoring

Bus duct is a system composed of metal plates as protective shells, conductive bars, insulation materials, at mga kaugnay na accessories. In the manufacturing process of bus ducts, manufacturers strive to adopt new technologies and processes to improve the safety and reliability of bus ducts, and the connection between two bus ducts is a key link that affects the safe operation of bus ducts. The connection part is fixed in the plug-in junction box, and by monitoring the temperature of the busbar, the operation status of the busbar duct can be understood, thereby improving the reliability of the busbar duct operation. The common busbar temperature measurement device is usually installed through a series of steps, fixed in the plug-in junction box, and the installation and disassembly process is complex and the connection is unreliable.

Specification for operating temperature of busbars

The allowable temperature for the busbar and switch is 700 ℃, and there should be no overheating during operation. The temperature test piece should not melt; The maximum allowable temperature for enclosed busbars is 900 ℃, the allowable temperature for the casing is 650 ℃, and the allowable temperature for busbar joints is not more than 1050 ℃.

How high temperature can the busbar joint withstand?

The allowable operating temperature of the busbar joint is 70 ° C (when the ambient temperature is+25 ° C). If there is a tin coating on the contact surface (such as ultrasonic tin coating), it is allowed to be raised to 35 ° C, and it is allowed to be raised to 100 ° C during flash welding.

The method of temperature measurement for busbars is as follows: (1) Color changing paint. (2) Test the temperature of the wax slice. (3) Semiconductor point thermometer (charged temperature measurement). (4) Infrared measuring instrument. (5) Sistema ng pagsukat ng temperatura ng fiber optic

The busbar joint can use a fluorescent fiber optic temperature measurement system, and the busbar trunking bridge can use a ipinamahagi ang fiber optic host ng pagsukat ng temperatura. The temperature measurement methods used in different application scenarios are different.

The power bus temperature measurement device and system relates to the field of power device temperature measurement technology, including a fiber optic temperature measurement host and a temperature sensing optical fiber set inside the power bus, with one end of the temperature sensing optical fiber connected to the fiber optic temperature measurement host; The temperature sensing fiber optic sends the sensed temperature data to the fiber optic temperature measurement host, which obtains the bus temperature based on the temperature data. Set the temperature sensing optical fiber inside the busbar, closer to the busbar, and unaffected by external environmental temperature, making temperature measurement more accurate.
