机运用电控系统完成机的起动、停机和检测保护,绝大部分记性特别是用于泉州干式变压器组的机都采用了电子调速系统,但其形式各有不同。如电站用4BT3.9—G2采用孚创(FORTRUST)C1000B转速控制器,A1000C电磁执行器,该执行安装在高压油泵的后端,直接驱动油量调节机构,这是一种全电子式电子调速结构。但有的机型如6CTA8.3—G2(采用ESD5500E转速控制器,ADB225G电磁执行器)、EQ6BT5.9(采用CFKMB—Z电控板,SK—1040—36电磁执行器),其电子调速系统对机的控制是通过对高压油泵上的机械调速器的操控来实现的,即在用电子调速器改装机组时,充分利用了现成的机械调速器。 电子调速系统的电磁执行器与机械调速器的连接有两种方式,其一是与机械调速器的停机手柄相连,其二是与机械调速器的调速手柄相连。(1)电调与机械调速器停机手柄连接 是将ADB225G旋转化比例电磁执行器与RSV机械调速器的停机手柄连接,其方式是使执行器的输出臂通过有2个关节轴承的杆系与机械调速器的停机组手臂连接在一起。停机组手柄转动,将通过销钉24使浮动杆3以小轴7为支点转动,带动供油齿杆移动改变供油量。执行器设有回位弹簧,将提供停机手柄反向转动的驱动力。注意:①执行器摆角的变化必须与负荷控制杆增与减负荷(油量)的方向一致;②执行器输出臂的相位角要保证与停机组和满负荷相对应。约10%和80%~90%;③运动杆系的运动必须灵活,不得有任何干涉。改装时不必拆掉机械调速器,而是利用它作为超速保护装置。实际应用时应将机械调速器的调速手柄重新固定在1560r/min,这是机械调速器还未起作用,不会对电子调速器产生干涉。而当电子调速器因失控造成飞机组(对泉州干式变压器组而言)时,机械调速器将把转速限制在1650r/min范围内。如果想要减小执行器的负荷,可将机械调速器里的起动弹簧卸掉。(2)电调与机械调速器调速手柄连接 若仅对机械调速其进行电控改装以完成自动起动和停机过程,而不使用电子调速模块,则电磁执行器可与调速手柄相连。电磁执行器拉动调速手柄时,改变的是调速弹簧的张力,实际上是改变了转速的设定值。更一般的方式是采用二位式电磁执行结构,起动后直接将调速手柄拉动到额定空转转速位置,其后将转速稳定及调节由机械调速完成,其工作运行过程参见RSV型调速器的中速工况。动力设备(深圳)有限公司,集团旗下专业运营泉州干式变压器的销售业务及其售后服务,是中国区获得授权的泉州干式变压器OEM成套厂家,长期与中字央企、大型房地产商、国际连锁酒店、著名建筑企业等单位建立战略合作伙伴关系。动力在中国布局五大泉州干式变压器组生产基地,泉州干式变压器售后服务点可辐射中国各省会及地级市区域。l泉州干式变压器区分:移动式泉州干式变压器、固定式泉州干式变压器、超静音式泉州干式变压器、机组载式泉州干式变压器。l常见泉州干式变压器功率(千瓦)范围:50KW至1000KW功率段。更多有关泉州干式变压器的最新产品和技术内容,请登录泉州干式变压器官网:
