   5SHK19501204可控硅 tlicon ControlldBRettie简称SCR是一种大功率电器元件，也称县闸管。具有体积小、效革高、寿命长等优点。在自动控制系统中，可作为大功率驱动器件实现用小功率控件控制大)率没备，它在交直洗电机调速系统、调功系统及随动系统中得到了广泛的应用、5SHX186004可控睦分单向可控硅和双向可控硅两种。双向可控硅也叫三端双向可控硅，简称THIAC。双向可控硅在结构.上相当于两个单向可控硅反向注接这种可控硅具有双向导通功能。其通断状态由控制极G决定。在控制极G上加正脉冲(或负脉冲可使其正向威反向导通。这种装置的优点是控制电胳简单没有反向耐压问题，因化特剂别适合做交流无触开关使用。5SHK19504大家使用的是单向最闸答，也就是人们常说的普通晶闸管，它是由四屋半导体材科组成的，有三E个PN结，对外有三个电极[图2a)】1第一层P型半导休引出的电极叫E极4第三剧P型半导林引咄的电极︰控制极G篇四N型半导体弓出的电极叫用极X。5SHK19604从最闸管的电胳符号图2b)可以看到)，它和二极管--样是一种单方向导电的器件，关键是多了一个控制极G，这就使它具有与二极管完全不同的工作特性

Technical parameters: ABB 5SHX1960LO004 Thyristor electronic components DC motor speed control system

5SHK19501204 thyristor tlicon ControlldBRettie SCR is a high-power electrical component, also known as the county gate tube. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power drive device to realize the control of large rate with small power control, it has been widely used in the AC direct washing motor speed control system, power regulation system and servo system, 5SHX186004 controllable one-way thyristor and bidirectional thyristor two. Bidirectional thyristor is also called three-terminal bidirectional thyristor, referred to as THIAC. Bidirectional thyristor in structure. On the equivalent of two one-way thyristor reverse injection This thyristor has a double pilot pass function. Its on-off state is determined by the control pole G. Add a positive pulse (or a negative pulse) to the control pole G to make it pass forward and reverse. The advantage of this device is that the control electric skeleton is simple and there is no reverse voltage problem, and the chemical agent is suitable for AC contactless switch use. 5SHK19504 We use a one-way gate answer, that is, people often say ordinary thyristor, it is composed of four houses of semiconductor materials, there are three E PN junction, Externally, there are three electrodes [FIG. 2a] 1 The electrode led by the first layer of P-type semiconducting is called E-pole 4 The electrode led by the third series P-type semiconducting forest: the electrode bowing out of the control pole G section is called pole X. 5SHK19604 From the most thyristor electrical symbol figure 2b) can be seen), it and diode - like is a single direction conductive device, the key is more than a control pole G, which makes it have completely different working characteristics with the diode
