Under-power protection 低功率保护
According to the actual situation of power supply network and protection system under mine, a long distance faults online monitoring program is presented for overcoming the short protection distance.
本文结合矿用供电网的实际情况和保护系统的现状,针对现有技术保护距离较短的缺点,提出了一种针对矿用供电线路的远距离故障在线监测的方案。
Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover-current protection. Special power-up sequencing is not required.
内部电路保护包括滞后热关机,欠压锁定(uvlo)和交叉电流保护。特别功率提升排序。
Safety protection, energy save and extend heater life. Auto power cut-off under the circumstances of standby for 30 minutes, failure of temperature test, PCB, heating element and low tip temperature.
当30分钟闲置, 或测温系统出现故障, 如焊咀温度低于警诫线, 发热芯或线路板发生故障时, 自动切断电源, 具安全, 省电及延长芯头寿命的优势。
