Application of Fluorescent Fiber Temperature Monitor in Abnormal Temperature Rise of Electrical Equipment

Te mau tao'a e vai ra i roto i te mau tao'a e, Te ravea hi'opoaraa maramarama, Te taata hamani titia mata i te fenua Taina

No te atea o te uira, te mau materia e rave rahi, Te mau mana'o tauturu no te haapiiraa, and mostly continuous operation of the 6kV distribution line in the oilfield, the electrical equipment of the substation supplying power to the line has the characteristics of heavy load and high current during operation. I roto i taua mau huru tupuraa ra, ia ore ana'e te mau tuhaa o te mau tauihaa i raro a'e i te reni e matara mai aore ra eita te mau tuhaa o te tuhaa tataitahi e taai - maitai - hia, e maraa te anuvera o te mau tauihaa no te mea e tamau noa te reira i te tere, te aravihi ore i te pae materia o te mau tauihaa uira. Mai te mea e, aita e itehia e e tata'ihia i te taime ti'a, E nehenehe te mau ati e tupu mai na roto i te veavea - rahi - roa - raa e te taheraa te mau vahi o te mau tauihaa. Te auraa ra, e parau, i roto i te tupuraa o te mau hape i roto i te mau matini roro uira, e tupu ïa te hoê maraaraa rahi o te anuvera. No reira, E mea faufaa roa ia hi'opo'a i te anuvera o te mau matini faito teitei i te taime tapuraa.

Common abnormal temperature rise in substation equipment

1. Abnormal temperature rise of fully enclosed electrical equipment

In recent years, oilfield substations have gradually promoted fully enclosed electrical equipment, which combines high-voltage components such as high-voltage circuit breakers, Te mau nota, and transformers into metal enclosed cabinets, such as GIS combination appliances and KYN series armored high-voltage switchgear. I te roaraa o te tereraa o te mau tauihaa uira i opani - roa - hia, mai te mea e, e tupu te hoê tuhaa o te reira i roto i te mau tauihaa i roto i te afata teu, e nehenehe te reira e faatupu i te anuvera tano ore i ni'a i te tuatiraa o te taata faatere. No te ti'araa i hunahia, operators cannot detect it in a timely manner. E nehenehe te reira e faarahi ohie noa i te hape, e tupohe i te mau tuhaa uira e e paapaa roa, e te haafifiraa i te mau matini i piha'i iho mai, Te hoê ati purumu ino mau i tupu i muri a'e i te hoê ati purumu in.

2. Abnormal temperature rise of high-voltage circuit breakers

I roto i te tereraa matarohia o te mau taata ofati ture, te ito e roaa mai na roto i te rave-tamau-raa i te ohipa, ua tauihia ïa ei ito ve'ave'a, e maraa te anuvera o te mau tauihaa uira, eiaha râ i nia ' ' e i te anairaa i faataahia; Mai te peu e mea tano ore te tuhaa haaati, e faatupu te reira i te anuvera o te mau tao'a uira i nia ' ' e i te anairaa i faataahia, Te faaoreraa i te mau taairaa puai e te u'ana, faarahi i te pato'iraa, e a faarahi atu â i te anuvera veavea, ua iti mai te mau faufaa o te matini e o te tino o te mau tao'a uira. Ia hau a'e te anuvera i te faito anuvera o te tumu parau, e faatupu te reira i te ino i roto i na taata e piti, i te pae hopea e tae atu ai i te hoê ati uira i reira eita te taata ofati e nehenehe e iritihia.

Ei hi'oraa, te haana auri i opanihia i roto i te mau tuhaa i raro i te api (Te mau mana'o tauturu no te haapiiraa) e faaohipa te taato'araa i te mau matini nene'iraa pereoo na'ina'i. Ia tura'i-ana'e-hia te raau i roto i te, mai te mea eita te puai e nava'i aore râ eita e nava'i, e faatupu te reira i te taairaa i rotopu i te mau tao'a puai e te mau tao'a e vai ra i roto i te tino, Te mau mana'o tauturu no te haapiiraa e te avatea. I te taime tapuraa, e tahe mai te toto na roto i te mau niuniu, o te nehenehe e faatupu i te tuhaa no te haapotoraa e o te arata'i atu i roto i te hoê ati ino no te paapaaraa te taato'araa o te mau mea.

3. Abnormal temperature rise at conductor connections

Te taairaa i rotopu i te mau tauihaa uira e rave rau i roto i te tuhaa i raro i te fenua, tei te huru ïa o te mau tao'a e faaohipahia no te hamani i te mau tao'a e vai ra i roto i te mau, e tae noa ' tu i te mau ravea huru rau mai te taairaa e te pereoo uta taata rahi e te pereoo uta taata o te amaa. No te taotiaraa o te faito voltage, e mea titauhia ia hi'opo'a i te mau titauraa no te atearaa e tae atu ai i te vahi papû e te tere-maitai-raa o te mau pereoo uta taata. No reira, ua tamauhia e ua tapirihia te hoê vairaa no te parururaa. No reira, ua rau te huru o te mau niuniu e tuati i rotopu i te mau matini o te ore e nehenehe e faaohipahia, mai te ti'araa teitei i ni'a i te repo e te taatiraa puai. Mai te peu e aita te mau tao'a e vai ra i nia i te tuatiraa e tapea - maitai - hia ra aore ra e horo ra no te hoê taime maoro, E nehenehe te mau mea no rapaeau mai mai te puai o te mata'i e te faaohipa - rahi - raa i te uira i te taime tâpûraa, e faatopa e e faaiti i te mau uaua, i te pae hopea, ua rahi roa te mau vahi farereiraa i te vahi tapearaa pereoo uta taata no te mea ua rahi roa te mau taairaa i rotopu i te mau taata, e nehenehe te reira e arata'i i te hoê ati rahi i ni'a i te mau pereoo uta taata e aore râ, i roto i te mau tuhaa atoa o te pereoo uta taata.

Fiber optic temperature online monitoring technology

1. Real time measurement of temperature data has been achieved, and operators can visually determine whether the equipment is running normally based on the operating temperature data, improving the timeliness and accuracy of discovering equipment defects caused by overheating.

2. The data received by the fiber optic temperature transmitter collection terminal (temperature monitoring device) can be compared with the set value to achieve functions such as over temperature alarm, effectively preventing equipment overheating accidents caused by poor contact and other reasons.

3. The installation range of fluorescent fiber optic temperature monitoring equipment can be selected to be installed entirely or only in high load circuits, which has the advantages of strong selectivity, flexibility and convenience, and can also achieve the goal of saving investment.

Application scope of fluorescent fiber optic temperature monitoring instrument

1. Fluorescent fiber optic temperature online monitoring technology can not only monitor the real-time online temperature of the connection points of the dynamic and static contacts of circuit breakers, busbar connections, isolating switch blade contacts, and other electrical equipment connection points, but also be used for temperature monitoring of electrical equipment such as dry-type transformers and high-voltage cable joints. Its application prospects are very broad.

2. The application of temperature online monitoring technology can fundamentally eliminate blind spots in temperature monitoring of all contacts of fully enclosed electrical equipment, solving the problem of undetectable temperatures in the past. Fundamentally changing the management mode of operating personnel’s periodic inspection of contact temperature, improving work efficiency, saving manpower and material resources, and achieving significant economic benefits.

3. Based on online temperature monitoring data, the operation status of electrical equipment can be determined, and the maintenance cycle and items can be determined, providing decision-making basis for substation status maintenance.

4. The real-time monitoring data of temperature online can serve as important node data for equipment operation monitoring in unmanned substations, providing strong technical support for substation operation monitoring and defect collection.

5. Real time online temperature monitoring can enable substation operators to promptly detect signs of high-voltage equipment failures and take effective measures in advance, which is of great significance for ensuring equipment operation safety and improving power supply reliability.
