AI Technical Summary
In the existing technology, there is insufficient research on the busbar breakdown phenomenon caused by the ejection of gas from low-voltage circuit breakers. In particular, it is difficult to measure the breakdown characteristics of the high-temperature gas outside the arc-extinguishing chamber, and there is a lack of joint research with the measurement of internal arc characteristics.
A measurement system for arc and arc-extinguishing chamber air-jet breakdown characteristics of a low-voltage circuit breaker was designed, including an arc characteristic measurement system and an air-jet breakdown characteristic measurement system. Through a capacitor charging and discharging circuit, an arc discharge circuit, a switching timing control circuit, and measuring equipment, the system enables synchronous measurement and high-speed photography of arc voltage and current parameters and breakdown voltage.
It enables simultaneous measurement of the arcing process and the gas ejection breakdown process of low-voltage circuit breakers, increases the means of studying busbar breakdown phenomena, and helps optimize circuit breaker design and testing techniques.
