Woodward 9905-372 同步负载控制功能 内置诊断
【产品详情】
9905-372 的环境规格如下:
工作温度:-40 至 +70 °C(-40 至 158 F)
存储温度:-55 至 +105 °C(-67 至 221 F)
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
该器件具有开放式 Delta PT 配置、500 Hz PWM 速度偏置和 120 Vac 输入电压。 伍德沃德 9905-372 型的额外功能包括:
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功能
反向功率继电器。
该型号提供相位匹配或滑差频率同步。使用这两种方法,通过使用实际滑差频率和断路器延迟值,可以预期实际断路器闭合时发电机和母线之间的最小相位差。9905-372 型具有自动死总线闭合功能,通过通信网络上的锁定技术,仅授予一个 DSLC 控制器死总线闭合权限。

【英文介绍】
The environmental specifications of 9905-372 are as follows:
Operating temperature: -40 to +70 °C (-40 to 158 F)
Storage temperature: -55 to +105 °C (-67 to 221 F)
Humidity: 95% at 38 °C
Mechanical shock: US MIL-STD 810C, Method 516.2, Procedures I, II, V
Electromagnetic sensitivity: ANSI/IEEE C37.90.2; Standard: ANSI C37.90.1-1989
Vibration: US MIL-STD 167, Type I
The device features an open Delta PT configuration, 500 Hz PWM speed bias, and 120 Vac input voltage. Additional features of the Woodward Type 9905-372 include:
Built-in diagnosis
Setup, metering and diagnostic functions are achieved through a handheld programmer terminal
Generator automatic handling
Voltage drop, base load and synchronous load control functions
Reverse power relay.
This model provides phase matching or slip frequency synchronization. Using these two methods, the minimum phase difference between the generator and the bus when the actual circuit breaker is closed can be expected by using the actual slip frequency and the circuit breaker delay value. Type 99005-372 has automatic dead bus closure function, which grants dead bus closure permission to only one DSLC controller through locking technology on the communication network.
