2 ignitor : - this is an electronic amplifier that receives electric current from the ballast and boosts voltage to ignite the arc light source in all environments . it initializes plasma discharge within the source by delivering a high - volt pulse to the electrodes 2 ignitor : -是一个从ballast接收电流并向所有环境中的arc light source释放电压的电子放大器,它通过向电极传递高脉冲来对等离子放电器进行初始化
Numerical simulation results indicate that , for low temperature dust particles , dust particles mainly exist in the area near the column center and their charge - number can be considered as a constant , while in the area where there are no dust particles , ion and electrons are in ambipolar diffusion ; for high temperature dust particles , both the distribution regions of dust particle and high ion density are expanded and dust charge - number is increasing with the distance from the center 计算结果表明：当尘埃粒子的温度较低时，尘埃粒子主要集中在圆柱形放电器的中心很小的区域，尘埃粒子携带的电荷几乎是一个常数，受尘埃粒子空间电荷的影响，离子在该区域的密度最高。在远离中心区域，离子和电子呈现双及扩散特点；当尘埃粒子的温度较高时，尘埃粒子分布的区域和高离子密度区域扩大，尘埃粒子离放电器中心越远，携带的负电荷越多。
However , by the time a lightning strike has traveled through the distribution network , surge arrestors will have dissipated a proportion of the charge , network impedance will have shaped the impulse and the residual energy can be represented in terms of its waveshape , and its peak current which is what will be present at a service entrance 然而，雷击经过电力网络进行传送以后，避雷放电器会将一部分能量泄放掉，网络的阻抗也会对电涌进行修整，而残余的能量将可以以它的波形来体现，其峰值电流也就是建筑物进入端将会出现的情况。
