Sistem pengukuran suhu serat optik neon untuk pemutus sirkuit switchgear, pabrikan-INNO

Switchgear tegangan tinggi yang dilengkapi dengan pemutus sirkuit vakum kereta tangan dan kereta tangan isolasi harus dilengkapi dengan sistem pemantauan online serat optik hotspot fluoresen (dengan minimal 8 titik deteksi per kabinet tegangan tinggi) untuk memantau kontak pemutus sirkuit, busbar, Kabel, dll. dalam waktu nyata.

Dengan berkembangnya perekonomian nasional, kapasitas jaringan listrik meningkat, tegangan jaringan listrik naik, dan stabilitas operasi dan pasokan jaringan listrik juga menghadapi persyaratan yang lebih tinggi. Status pengoperasian peralatan listrik utama secara langsung mempengaruhi apakah sistem tenaga listrik dapat beroperasi dengan aman dan andal
Switchgear tegangan tinggi digunakan dalam sistem tenaga untuk mengontrol, melindungi, dan mengisolasi peralatan listrik. Ini mengintegrasikan sejumlah besar komponen listrik, termasuk pemutus arus tegangan tinggi, saklar isolasi, dan sekering, di dalam casing logam yang diarde. The main function of the switchgear is to open, menutup, kontrol, and protect electrical equipment during the process of power generation, Penularan, distribusi, and energy conversion in the power system;

Sekarang, with the widespread use of fully enclosed high-voltage switchgear in 10kV power grids, higher requirements have been put forward for its reliability. Namun, abnormal heating of electrical joints inside the switchgear during long-term operation has become a common problem among many factors affecting the safe operation of the switchgear. In response to the current situation of temperature monitoring of high-voltage equipment, the online monitoring system for high-voltage electrical contact temperature has solved the problems encountered in conventional temperature monitoring methods and played a good warning role in avoiding high-voltage electrical equipment accidents.

Dalam beberapa tahun terakhir, multiple fires and large-scale power outages have occurred in the power system due to equipment overheating. Analysis shows that 40% of the annual power accidents in China are caused by overheating of high-voltage electrical equipment; In power supply systems that use high-voltage switchgear and power cables, atas 70% of cable operation failures are caused by increased contact resistance and overload at the connection points, resulting in excessively high joint temperatures. A 110kV substation has experienced a prolonged power outage due to the heating and ignition of the feeder cable joints and switch primary contacts, resulting in the burning of three 10kV fully enclosed high-voltage switches and causing significant economic losses. In order to ensure the reliability of power supply and the continuity of production, cable joint temperature measurement has become a standard configuration for high-voltage switchgear in large local chemical enterprises. Namun, due to the reliability of technology and high installation costs, it has not been widely promoted. With the maturity of technology and the reduction of costs, it is believed that there will be a great market demand.
