Electrical faults is one of the main causes of fires in the industrial field, especially accidents caused by electric arcs. According to statistics, at least 20% of fires in the industrial field are related to electrical faults. As a high-temperature and high-energy phenomenon, electric arcs are not only the direct cause of fires, but can also cause serious damage to equipment and personnel.
Why are arcs dangerous?
The temperature of the arc can reach thousands of degrees Celsius, which is enough to melt nearby metal materials such as copper or aluminum. Once the arc is formed, not only will the metal melt, but the air will also expand due to the high temperature, which will cause an explosion effect. This explosion can project molten metal several meters away, increasing the risk of fire spread. Additionally, the high noise levels produced by arcs may damage eardrums, while air ionization effects pose a hazard to the operating environment.
How to protect effectively?
In order to cope with the risks brought by electrical faults and arcs, it is crucial to choose the appropriate electrical equipment. In 12kV voltage systems, VTZ-12 Vacuum Circuit Breaker has become an important means of protecting against electrical fires due to their high reliability and excellent arc extinguishing ability.
VTZ Series Vacuum Circuit Breakers effectively limit the formation and spread of arcs by interrupting the current in a vacuum environment:
Rapid Arc Extinction
The vacuum medium in VCBs has excellent insulating properties, enabling arcs to be extinguished almost immediately after formation, preventing further heat dissipation.
Risk Reduction
Compared to traditional circuit breakers, VCBs avoid secondary explosion risks associated with oil or gas arc-extinguishing mediums, significantly reducing fire hazards.
Broad Applicability
Whether in general industrial settings or high-risk environments such as chemical plants and mining industries, VCBs offer efficient protection.
Importance and recommendations
Electrical faults, particularly arc-induced fires, present significant challenges to industrial operations. By choosing advanced protective equipment such as vacuum circuit breakers, enterprises can not only effectively reduce the probability of fire, but also improve operational safety, ensure production continuity and personnel safety. If you are facing the need to upgrade your electrical system of 12kV, you may consider our VTZ-12 Vacuum Circuit Breaker, whose excellent performance will help you build a safer and more reliable power environment.
