一种检测短路保护的新型煤电钻综合保护装置
A New Type of Electric Drill Comprehensive Protection Device Based on the Current Changing Rate to Test Short Circuit Protection
【摘要】 新装置采用全数字化抗干扰设计。解决了现有产品短路保护动作时间长、保护距离短、打钻时短路保护误动作、抗干扰能力差、精确度低、调整困难等问题。
【Abstract】 The new system is digital anti-jamming design. It solved the existing products’ long time short-circuit protection action, short distance protection, short-circuit protection wrong working when drilled, weak anti-jamming capabilities, low accuracy, difficult adjustment and other issues.
