Kilang pengeluar mana yang bagus untuk sistem pemantauan sensor cahaya arka-INNO

Dengan perkembangan industri kuasa dan peningkatan permintaan untuk beban grid kuasa, ia diperlukan untuk memastikan keselamatan dan kestabilan penjanaan dan bekalan kuasa semasa operasi sistem kuasa, dan menyediakan sumber kuasa yang boleh dipercayai untuk pengguna. Namun begitu, insiden kerugian ekonomi yang ketara dan korban yang disebabkan oleh kerosakan litar pintas arka sering berlaku. Untuk mengelakkan kerosakan litar pintas arka daripada menyebabkan kemudaratan yang lebih besar, ia secara amnya diperlukan untuk memotong kerosakan dalam masa tindakan perlindungan kurang daripada 100 milisaat.

Mengapa alat suis memerlukan pemantauan cahaya arka

Oleh kerana strukturnya yang padat, suis voltan sederhana dan rendah sering mengalami kerosakan arka yang kuat apabila berlaku litar pintas. Dalam kebanyakan kes, it needs to be cut off by the higher-level backup protection when the switchgear fails. If the fault cannot be removed in a timely manner, the arc fault will release a huge amount of energy in a short period of time, which is enough to burn down the switchgear, resulting in a long recovery time for power supply, causing significant economic losses and impacts. Arc protection uses arc light and fault current as dual criteria. In the event of an arc short circuit fault, the fault can be cut off in milliseconds without causing significant impact on the switchgear. With the increasing attention paid to power distribution networks, arc protection is increasingly being used in medium and low voltage switchgear. Arc light often occurs inside the distribution medium voltage switchgear. Alat suis voltan sederhana pengedaran ialah hab bekalan kuasa sistem bekalan kuasa tambahan di seluruh loji. Apabila lampu arka dilitar pintas di dalam suis, kuasa lampu arka boleh mencapai 100MW. Tenaga yang dijana oleh pembakaran arka meningkat secara eksponen dengan masa pembakaran dan nilai perubahan arus litar pintas arka, mengakibatkan suhu tinggi yang dihasilkan oleh pembakaran. Tekanan tinggi menyebabkan gas di dalam kabinet mengembang dengan cepat, mencapai kemuncaknya dalam masa yang singkat. Akhirnya, ia akan memusnahkan komponen secara beransur-ansur, bar tembaga, dan deretan alat suis. Cahaya arka terang dan gas toksik juga menyebabkan kemudaratan yang ketara kepada kesihatan manusia.

Punca penjanaan cahaya arka

Apabila bekalan kuasa dan peralatan transformasi, peranti penukar industri, and special devices in the power system malfunction, a huge arc light will be generated. When the arc light occurs, it will generate a large amount of light energy radiation and high temperature radiation, which have a great destructive effect on the power system and sometimes even cause operator casualties. Pada masa ini, when conducting arc light detection, arc light sensors are mostly used to detect the intensity of arc light, and then determine whether the system power needs to be cut off based on the intensity of arc light. Short circuit is one of the most common circuit faults in the power grid. When a circuit experiences a short circuit, an arc is generated, and the light emitted by the arc is called arc light. Arc light has a strong luminosity and generates very high energy. Controlled arc light is widely used in lighting, electrical welding, steelmaking, and satellite engines. Namun begitu, when the arc light is uncontrolled, it is very dangerous, and the arc light generated during the circuit short circuit process is uncontrolled arc light, which has great harm. Selain itu, the temperature of the arc is extremely high (up to 13000K or above). When an arc is generated, the gas around the arc will ionize, and the ionized gas will rapidly expand. The expansion speed of the gas ionized can refer to the gas expansion speed data during the formation of the welding arc. The rapidly expanding gas can vaporize all objects it encounters. If an arc is generated inside the switchgear, all power components installed inside the switchgear will be severely damaged, menyebabkan kerugian yang ketara. Selain itu, masa pemulihan bekalan kuasa selepas kemalangan suis adalah panjang. Jika suis dalam keadaan tertutup, gas suhu tinggi yang dijana dalam tempoh masa yang singkat semasa penjanaan arka juga boleh menyebabkan suis meletup, menimbulkan ancaman kepada keselamatan peribadi pekerja dan keselamatan harta perusahaan. Terdapat ancaman yang serius.

Sistem pemantauan sensor cahaya arka elektrik

Cahaya arka adalah fenomena penyalaan litar pintas arka, yang mempunyai ciri-ciri seperti suhu tinggi dan kecerahan tinggi, dan sering berlaku di dalam kabinet suis. Disebabkan oleh ciri suhu tinggi cahaya arka, jika cahaya arka tidak dirawat tepat pada masanya, the high temperature formed by the arc light will cause the conductor that produces the arc light and the materials adjacent to the conductor to melt or sublimate, leading to circuit damage and affecting the normal operation of the circuit. Dalam kes yang teruk, it may even lead to a fire. Oleh itu, it is necessary to detect arc light in order to handle it in a timely manner when it occurs. Due to various short circuits in the power system, arc light can be caused. In order to detect the arc light in a timely manner and safely and quickly cut off the arc light, sistem pemantauan gentian optik manufacturers have launched an arc light detection system that uses fiber optic transmission signals. The arc light monitoring system can detect an arc sensor in a very short time. The arc light sensor, combined with other control and execution units, can quickly cut off the power supply after detecting the arc, thereby avoiding greater damage caused by the influence of the arc light. Fiber optic transmission of signals can not only reduce the response time of the detection system, but also avoid electromagnetic interference and improve the reliability of the system.
