Woodward 8271-468 发电机装载控制 具有米色外壳

【产品详情】

发电机负载控制单元 8271-468 的标准商业功能被编程到该单元中。这允许设备控制用户选择的发电机组承担的电气负载的调整。8271-468 的操作和调整是否符合所需规格，很大程度上取决于设备对电源系统的使用。

它可以使用隔离电源系统，也可以使用与无限总线并联的本地系统。在隔离系统中，8271-468 发电机负载控制与每个负载分配和速度控制一起使用。它连接到两者的并联线，可以检测发电机的负载。该装置的输出设计用于偏置线路电压，以控制整个系统负载的一小部分。制造商对 12 个电线端子进行了适当的标记以供使用。 如果与无限总线并联，则在设备满载时测量发电机负载控制的负载信号测试插孔处的电压。

在同步并联应用中，发电机负载控制部件号 8271-468 在市电保持频率的同时调节功率。与并联的标准下垂操作相比，这种类型的控制系统的一个优点是，在与公用设施分离时，现在隔离的总线会自动处于同步速度控制之下，而无需操作员重新调整速度设置。

【英文介绍】

The standard commercial functions of the generator load control unit 8271-468 are programmed into this unit. This allows the device to control the adjustment of the electrical load undertaken by the user-selected generator set. The operation and adjustment of the 8271-468 to the required specifications largely depends on the use of the power system by the device.

It can use an isolated power supply system or a local system in parallel with an infinite bus. In isolation systems, the 8271-468 generator load control is used with each load distribution and speed control. It is connected to the parallel line of the two and can detect the load of the generator. The output of the device is designed to bias the line voltage to control a small portion of the overall system load. The manufacturer appropriately marked 12 wire terminals for use. If connected in parallel to an infinite bus, the voltage at the load signal test jack of the generator load control is measured when the device is fully loaded.

In synchronous parallel applications, the generator load control part number 8271-468 regulates power while the mains maintains frequency. One advantage of this type of control system over standard droop operation in parallel is that when separated from utilities, the now isolated bus is automatically under synchronous speed control without the need for the operator to readjust the speed Settings.
