The lowest cost approach is to update an existing panel by adding compatible smart circuit breakers to select circuits, though most require either extra space in the panel for wider breakers or a secondary panel for all of the breaker control units. This eliminates the need for changing out a...
i lost a sell of a camper because of this brand FPE, home inspector wouldn't look inside metal box-he said the way it was made that everything would fall out if the cover was taken of ( BS ) took cover off -looked like any other panel box. the problem is the breaker not the ...

电火花是一种自激放电,其特点如下: 火花放电的两个电极间在放电前具较高的电压,当两电极接近时,其间介质被击穿后,随即发生火花放电。伴随击穿过程,两电极间的电阻急剧变小,两极之间的电压也随之急剧变低。火花通道必须在维持暂短的时间(通常为10-7-10-3s)后及时熄灭,才可保持火花放电的“冷极”特性(即通道能量...
简单控制系统是只对一个被控参数进行控制的单回路闭环控制系统。是最基本的过程控制系统。是构成复杂过程控制系统的基础。典型结构框图如下: 过程控制系统设计的主要内容: 控制方案的设计:核心,包括合理选择被控参数和控制参数、信息的获取和变送、调节阀的选择、调节器控制规律及正、反作用方式的确定等。
