  • Reasons for high temperature alarm in high voltage distribution box

    Reasons for high temperature alarm in high voltage distribution box

    Transformers operate under high electrical loads, generating heat as a byproduct. Excessive heat can degrade insulation materials, leading to short circuits, reduced efficiency, and ultimately, transformer failure. Advanced thermal monitoring of electrical equipment is actually the topic of this technical article. Medium voltage circuit breakers, switchgear, and substations are frequently targets of thermal. Temperature monitoring in high-voltage busbar systems is vital for preventing faults, yet difficult due to electrical hazards, limited accessibility in switchgear cabinets, and interference risks in traditional contact-based methods. The function of high-voltage switchgear is to turn on, off, control and protect the power system in the process of power generation, transmission, distribution and energy conversion. When a transformer operates, it reaches a state where heat generation and heat dissipation are balanced, and the temperature of each part. High transformer temperature results from insulation aging, overload, poor cooling, or mechanical faults. Learn key causes and prevention strategies here.
