Woodward 9905-369 提供相位匹配或滑移频率同步

【产品详情】

部件 9905-369 具有开放式 Delta PT 配置、0.5–4.5 Vdc 速度偏置和 240 Vac 输入电压。该控制器的额定工作温度为 –40 至 +70 °C（-40 至 158 F），存储温度为 –55 至 +105 °C（-67 至 221 F）。9905-369 的其他环境规格包括：

湿度。。。。。。38 °C 时为 95%

机械冲击 ......US MIL-STD 810C，方法 516.2，程序 I、II、V

电磁敏感度 ......ANSI/IEEE C37.90.2;标准：ANSI C37.90.1-1989

振动。。。。。。US MIL-STD 167，I 型

部件 9905-369 的一些功能是内置诊断;通过手持式编程器终端实现设置、计量和诊断功能;发电机自动装卸;压降、基本负载和同步负载控制能力;和反向功率继电器。

第 9905-369 部分提供相位匹配或滑移频率同步。两种方法的实际滑差频率和断路器延迟值用于预测两种方法在实际断路器闭合时发电机和母线之间的最小相位差。该控制器具有自动死总线闭合功能，其中只有一个 DSLC 控件通过通信网络上的锁定技术被授予死总线闭合权限。

该控制器具有三相真有效值功率感应功能，即使在电压波动和相位负载不平衡的情况下也能确保精度。内部数字基本负载基准可通过开关输入升高或降低。也可以通过 4–20 mA（或 1–5 Vdc）模拟输入进行远程负载设置。当操作模式改变时，装载和卸载斜坡可确保平稳过渡。此过程以用户选择的速率开始，一直持续到控制在其目标的 5% 以内，此时它转变为动态控制。

【英文介绍】

Part 9905-369 has an open Delta PT configuration, 0.5-4.5 Vdc speed bias, and 240 Vac input voltage. The controller is rated for operating temperatures of -40 to +70 °C (-40 to 158 F) and storage temperatures of -55 to +105 °C (-67 to 221 F). Additional environmental specifications for the 9905-369 include:

The humidity 95% at 38 °C

Mechanical impact...... US MIL-STD 810C, Method 516.2, Procedures I, II, V

Electromagnetic sensitivity...... ANSI/IEEE C37.90.2; Standard: ANSI C37.90.1-1989

vibrate US MIL-STD 167, type I

Some of the functions of part 9905-369 are built-in diagnostics; The function of setting, measuring and diagnosing is realized through the handheld programmer terminal. Generator automatic loading and unloading; Voltage drop, base load and synchronous load control capabilities; And reverse power relays.

Part 99005-369 provides phase matching or slip frequency synchronization. The actual slip frequency and circuit breaker delay values of the two methods are used to predict the minimum phase difference between the generator and the bus when the actual circuit breaker is closed. The controller has automatic dead bus closure function, where only one DSLC control is granted dead bus closure permission through locking technology on the communication network.

The controller has a three-phase true RMS power sensing function to ensure accuracy even in the case of voltage fluctuations and phase load imbalance. The internal digital baseload reference can be raised or lowered by switching input. Remote load Settings can also be performed with 4-20 mA (or 1-5 Vdc) analog inputs. Loading and unloading ramps ensure a smooth transition when operating modes change. This process starts at the rate chosen by the user and continues until the control is within 5% of its target, at which point it transitions to dynamic control.
