Approach to analysis of the circuit time field in rl series interrupt 串联断流电路时域分析的探讨
Circuit time constant 回路时定数
Short circuit time should not longer than 5s and the temperature should not exceed 160 电缆的短路时间应不大于5s ,短路温度应不超过160
The co2 welding process needs the special external characteristic and dynamic characteristic of power source for there are alternately arcing time and short circuiting time at the period of short - circuiting co2 welding 在采用短路过渡方式的co2焊过程中,短路和燃弧过程交替发生,因此它对电源的外特性和动特性有特殊的要求。
Apply the vacuum arcing chamber , air insulation and includes electric spring operation mechanism so that the product arcing ability is strong , short open circuit times is many , no fire and explosion danger , convenient operation , it is the product of good performance , and strong usefulness 采用真空灭弧室,空气绝缘配以电动弹簧操动机构,使得产品灭弧能力强,短路开断次数高,无火灾爆炸危险,操作方便,是一种性能优良,实用性较强的产品。
