      电流I2l的方向从T2流向T1。由特性曲线可知,这时双向可控硅触发导通规律是按第二象限的特性进行的,又因为触发信号是正向的,所以把这种触发叫做“象限的正向触发”或称为I+触发方式。(2)如果主电极T2仍加正向电压,而把触发信号改为反向信号(图5b),这时双向可控硅触发导通后,通态电流的方向仍然是从T2到T1。我们把这种触发叫做“象限的负触发”或称为I-触发方式。(3)两个主电极加上反向电压U12(图5c),输入正向触发信号,双向可控硅导通后,通态电流从T1流向T2。双向可控硅按第三象限特性曲线工作,因此把这种触发叫做Ⅲ+触发方式。(4)两个主电极仍然加反向电压U12,输入的是反向触发信号(图5d)。陕西省SANIL开关SD-12M,SD-12MB,SD-12MP,

      “拍砖”、“吐槽”可以理解。但这位负责人进一步指出,法律的生命力在于严格执行,交通法律法规涉及亿万驾驶人。据介绍,元月1日至3日18时,全国没有发生重特大道路交通事故,没有发生长时间、长距离交通拥堵,交通形势平稳,道路秩序良好。全国共发生涉及人员伤亡的道路交通事故1204起,同比下降22%。交通违法行为也大幅下降,其中违反道路交通信号灯通行2157起,同比下降66%;酒后驾驶124起,同比下降72%;涉牌涉证严重交通违法行为7822起,同比下降53%。由此可见,新规在规范驾驶行为、减少交通违法、预防重大交通事故等方面的积极作用已初步显现。近十年机动车保有量快速增长,2012年保有量达2.4亿辆。陕西省SANIL开关SD-12M,SD-12MB,SD-12MP,

      现大多采用变频调速器了,因为变频调速器的节能效果有30%左右。此外,变频器价格也从早期的每千瓦1000元左右下降到每千瓦只有200多元(大功率),价格下降十分显著。如今的工矿企业对变频器的应用已经普及了,几乎涵盖了所有领域,不夸张地说,凡是用到电动机的地方肯定有变频调速器的身影。而且变频调速器具备了电动机所需要的起动效果和节能效果。科技进步决定市场占有,这就是为什么软起动器市场发展空间会逐步下降,而变频器市场占有率飞速提高的主要原因。变频器产业的国产化水平已经有了质的突破,国产变频器的市场份额也在逐步提升,但是和国外品牌在技术上相比,还是有一定距离。目前谈超越还为时过早,因为我们在变频技术领域的研究、开发方面。陕西省SANIL开关SD-12M,SD-12MB,SD-12MP,

      PAM需要同时调节两部分:整流部分和逆变部分,两者之间还必须满足Ku和Kf间的一定的关系,故其控制电路比较复杂。2.脉宽调制(PWM)把每半个周期内,输出电压的波形分割成若干个脉冲波,每个脉冲的宽度为T1,每两个脉冲间的间隔宽度为T2,那么脉冲的占空比Υ=T1/(T1+T2)。这时,电压的平均值和占空比成正比,所以在调节频率时,不改变直流电压的幅值,而是改变输出电压脉冲的占空比,也同样可以实现变频也变压的效果。当电压周期增大(频率降低),电压脉冲的幅值不变,而占空比在减小,故平均电压降低。此法的特点是,变频器在改变输出频率的同时,也改变输出电压的脉冲占空比(幅值不变)故称为脉宽调制,常用PWM(Pulsewidthmodulation)表示。陕西省SANIL开关SD-12M,SD-12MB,SD-12MP,
