Woodward 9905-711数字同步器  不具有功率因数控制

【产品详情】

由伍德沃德制造，部件号 9905-711 是基于微处理器的 DSLC 数字同步器和负载控制单元。该型号不具有功率因数控制或过程控制功能，因为它是简化的升级级别DSLC部件号。它适用于不需要集成功率因数或过程控制的应用。

型号 9905-711 设计用于与伍德沃德速度控制器和自动电压调节器（或其他兼容设备）一起使用时对三相发电机组进行并联、同步、加载和卸载。内置诊断功能;发电机自动装卸;通过手持式编程器终端实现设置、计量和诊断功能;压降、基本负载和同步负载控制能力;反向功率继电器只是其中的一些可用功能。

9905-711 具有 120/240 电压输入和 1-5 Vdc 的速度偏置。这款 WYE PT 配置装置的额定工作温度为 –40 至 +70 °C（-40 至 158 F），存储温度为 –55 至 +105 °C（-67 至 221 F）。

9905-711 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

9905-711 提供相位匹配或滑差频率同步。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。

【英文介绍】

Manufactured by Woodward, part number 9905-711 is a microprocessor-based DSLC digital synchronizer and load control unit. This model does not have power factor control or process control functions as it is a simplified upgrade level DSLC part number. It is suitable for applications that do not require integrated power factor or process control.

Model 9905-711 is designed to parallel, synchronize, load and unload a three-phase generator set when used with a Woodward speed controller and automatic voltage regulator (or other compatible equipment). Built-in diagnostic function; Generator automatic loading and unloading; The function of setting, measuring and diagnosing is realized through the handheld programmer terminal. Voltage drop, base load and synchronous load control capabilities; Reverse power relays are just some of the features available.

The 9905-711 has a 120/240 voltage input and a 1-5 Vdc speed bias. The WYE PT configuration 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).

Other environmental specifications for the 9905-711 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

The 9905-711 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.
