电弧触发器稳态温度场计算及其优化设计

Optimization Design and Calculation on Steady-state Temperature Field of Arc Trigger

为了计算电弧触发器稳态温升,本文建立了电弧触发器二维稳态温度场模型,采用matlab自编程方法计算电弧触发器稳态温度场,并通过温升实验验证模型的正确性。针对圆孔型电弧触发器,本文通过保持狭颈总截面不变,来保证弧前时间一致,并在此条件下研究不同狭颈数对电弧触发器稳态温升的影响规律,以此对电弧触发器进行优化设计。

To calculate the steady-state temperature rise of arc trigger, two-dimensional steady-state temperature field model of arc triggers is built to calculate the steady-state temperature field of arc triggers through programming by use of MATLAB, and the model is validated through temperature-rise tests. By keeping the same total cross sections of narrow neck of the circular-arc hole triggers, the triggers arced simultaneously is ensured. The effects law of different number of narrow necks on steady-state temperature rise of arc triggers is studied under this condition, and the arc trigger design is optimized.
