一般电热毯有高温、低温两档。使用时，拨在高温档，入睡后总被热醒；拨在低温档，有时醒来会觉得温度不够。这里介绍一种电热毯温控器，它可以把电热毯的温度控制在一个合适的范围。         工作原理：    电路如图所示。图中IC为NE555时基电路。RP3为温控调节电位器，其滑动臂电位决定IC的触发电位V2和阀电位Vf，且V5=Vf=2Vz。220V交流电压经C1、R1限流降压，D1、D2整流、C2滤波，DW稳压后，获得9V左右的电压供IC用。室温下接通电源，因已调V2Vz，V6≥Vf时，IC翻转，3脚变为低电平，BCR截止，电热丝停止发热，温度开始逐渐下降，BG1的ICEO随之逐渐减小，V2、

霍尔辛赫煤矿大采高工作面斜长由220 m增加到260 m后,在工作面推进速度保持不变的情况下,工作面生产能力可提升58万t/a。根据刮板输送机生产能力校核,现有刮板输送机的装机功率偏小,不能满足大采高加长工作面上行运输的要求。通过技术经济比较,将现有SGZ-1000/2×855型刮板输送机改造为SGZ-1000/3×855型刮板输送机,投资603.9万元,实现总装机功率为2 565 k W、能够满足260 m长大采高工作面产能3.7 Mt/a的生产需要。
