－1－九、固体继电器三相移相触发器模块(SSR-3JK)固体继电器三相移相触发器模块（以下简称SSR-3JK）内部集三相电相位检测、移相电路、控制电路和三路单相随机型固体继电器触发电路于一体，在由我公司提供的三相同步变压器模块（型号为TB-3）的支持下，不需外部任何电路或工作电源，便可以自动控制或电位器手动控制，产生三路可改变导通角度的脉冲信号再去分别控制三路单相随机型固体继电器，即可实现三相负载电压从0V到电网全电压的无级可调。按控制信号的不同，SSR-3JK分E、F、G和H型等四类，以下为规格型号表。CON0-5V：E型CON0-10V：F型CON4-20mA：G型CON1-5V：H型SSR-3JKESSR-3JKFSSR-3JKGSSR-3JKH为方便说明，下面以0-5V控制信号为标准作介绍，（型号简称SSR-3JK）SSR-3JK外形尺寸图三相同步变压器模块TB-3外形尺寸图

－2－有关技术指标及应注意的问题：1、整个电路可应用于380V（300V-400V）、50Hz的电网上，主电路中三相进线（R、S、T）无相序要求，但进线和固体继电器、TB-3、SSR-3JK输出端间（如R对应的SSR1和CON1）必须严格一一对应，否则系统不能正常工作。2、CON对COM必须为正，如极性相反则输出端失控（全开或全闭）。当控制端CON从0-5V改变时，交流负载上的电压从0伏到最大值可调（对阻性负载而言）。其中CON在0-0.8V左右时为全关闭区域，可靠关断模块的输出；CON在0.8V-4.6V左右为可调区域，即随着控制电压的增大，导通角α从180°到0°线性减小，交流负载上的电压从0伏增大到最大值；CON在4.6V-5V左右时为全开通区域，交流负载上的电压为最大值（接近电网电压）。3、CON对COM的输入阻抗分E、F和H型均为大于等于30K欧；G型为250欧。+5V电压信号只提供给手控电位器用，不作它用，所选用的电位器阻值在2-10KΩ间，注：4-20mA的G型不能用电位器手动调节，此时+5V端也没有用处。4、SSR-3JK的四个COM在模块内部均相连，为弱电“地”，(与同步变压器的中心线的“地N”为全隔离)在自动控制方式时与外电路控制的直流“地”相连。5、三相负载的三相功率应均衡。负载为Y形接法时，Y的中心点接与不接中心线均可，但接中心线时高次谐波对电网干扰要比不接中心线时大。同步变压器TB-3上的N线必须可靠接零线。6、SSR-3JK和TB-3本身发热很小，不需要安装在散热器上。7、三相交流异步电机的调速应采用变频器，只有风机类、水泵类电机在要求不高的场合可采用三相调压模块。三相电机软起动应采用电压、电流闭环控制。8、负载需要线性调压、稳压，请见说明书（十一）电压负反馈模块。9、由于SSR-3JK一方面通过同步变压器TB-3与电网隔离，另一方面通过三路固体继电器与电网隔离，因此SSR－3JK模块在弱电工作下极为可靠，并且即使三相负载发生短路而烧毁固体继电器后，SSR-3JK也不会损坏。由于这一原因，由SSR-3JK组成的三相调压系统比较合理：一方面比我公司生产的三相移相触发器模块调压系统（SX-JKA加六个单向可控硅）连线更为简便可靠，即使产生故障造成的损失也较小：SSR-3JK系统短路时只损失一只或二只SSR，而SX-JKA系统不但损失可控硅，而且还可能造成SX-JKA模块的损坏；另一方面也比我公司或其它公司生产的三相调压模块（移相触发电路与可控硅为一体）更为可靠，因为三相调压模块集六个单向可控硅于一体，由于体积小发热量大、散热不良而造成不可靠，在负载过流时所造成的损失则更不能相提并论。SSR-3JK（TB-3）与我公司生产的随机型固体继电器相匹配，用户购买SSR-3JK调压系统时，只需要提供负载的类型（如电加热、变压器、风机负载等）和功率大小及控制信号，我公司即可提供与之对应的SSR-3JK（TB-3）、三只随机型SSR和一块散热器（其中三只长条状固体继电器可安装在带风扇的A系列散热器上；三只长方状固体继电器可安装在E-70、F-120或G-220的散热器上作为一个功率单元）。杭州西子固体继电器有限公司产品说明书
