Circuit Breakers

0902373 Application Field and Working Principle

Circuit breakers are indispensable components in the process of electric power generation, transmission and distribution. They are used to protect circuits or equipment from overload or short-circuit currents. The 0902373 is produced by Southland Electric, it can accurately and reliably protect a wide range of high-voltage and medium-voltage power systems, satisfying various demands in the field of fast-paced trends of power systems. 0902373 has low-consumption design and low contact-gap voltage drop. It is a full-vacuum circuit breaker, formed of vacuum interrupter, arc chute, operating mechanism, and accessories. It has various parameters and can protect power systems in various voltage levels, with ratings up to 38kV and beyond. The 0902373 has a simple, reliable and long-life working principle, making it ideal for applications such as distribution system, power-up and power-down of power equipment, arc extinguishing, short circuit and overload protection. The 0902373 works with a cadmium sulfide interrupter, which serves as a contact between the electrodes when the current flows. When the electric current overloads, the interrupter makes contact between the electrodes and shorts out the circuit. The contact between the electrodes causes an arc to form, creating a large amount of heat. This heat melts the cadmium sulfide interrupter, causing it to vaporize. The vapor then quickly expands due to the heat of the electric arc, creating a high-pressure environment. The resulting pressure breaks the arc, stopping the flow of current. When current flows, the contact between the electrodes remains intact and no arc is formed. This is because the contact between the electrodes helps dissipate the current. When the current overloads, the contact between the electrodes is disrupted and the electric arc is created, causing the pressure buildup. The 0902373 is a reliable and low-consumption product that is used in a variety of power applications. It is easy to use and has a long working life. The 0902373 is also designed to provide protection from short circuits, providing protection from current faults. When a short circuit occurs, the current will rise quickly, resulting in high-pressure electrical arcing and noise. If the current rises above the designed rating, the 0902373 will instantly detect the hazard, causing it to break the circuit and protect the user and their equipment from potential harm. In conclusion, the 0902373 is a versatile and efficient circuit breaker that serves as a reliable and low-consumption solution for a variety of power applications, including distribution systems, arc extinguishing, short circuit and overload protection. It is easy to use and has a long working life.
