Woodward 9905-354 数字同步器  发电机自动装卸 

【产品详情】

伍德沃德 9905-354 型是基于微处理器的 DSLC 数字同步器和负载控制。当与伍德沃德速度控制器和自动电压调节器一起使用时，该控制器设计用于并联、同步、加载和卸载三相发电机组。

9905-354 的一些功能包括：

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。

9905-354 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。

在安装过程中可能启用或禁用的其他同步器功能包括：

延时自动多色重合闸

电压匹配

自动重新同步

同步器超时报警

使用 9905-354 DSLC 控制器时，可通过开关输入升高或降低内部数字基本负载基准。可通过 4–20 mA 模拟输入进行远程负载设置。装载和卸载斜坡可确保在操作模式改变时平稳过渡。

为防止静电损坏，在使用或靠近控制器时应遵循某些预防措施，例如在对 DSLC 进行维护之前触摸并握住接地的金属物体（管道、机柜、设备等）以将您身体上的静电释放到地面，在对控制器进行维护时穿着天然纤维衣服， 并使塑料、乙烯基和聚苯乙烯泡沫塑料材料尽可能远离控制器、模块和工作区域。

【英文介绍】

The Woodward Model 9905-354 is a microprocessor-based DSLC digital synchronizer and load control. When used with Woodward speed controllers and automatic voltage regulators, the controller is designed to parallel, synchronize, load and unload three-phase generator sets.

Some of the features of the 9905-354 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.

The 9905-354 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.

Other synchronizer features that may be enabled or disabled during installation include:

Delay automatic multi-color reclosing

Voltage matching

Automatic resynchronization

Synchronizer timeout alarm

When using the 9905-354 DSLC controller, the internal digital base load reference can be raised or lowered by switching input. Remote load Settings are possible with 4-20 mA analog inputs. Loading and unloading ramps ensure smooth transition when operating mode changes.

To prevent static damage, you should follow certain precautions when using or near the controller, such as touching and holding grounded metal objects (pipes, cabinets, equipment, etc.) to release static electricity from your body to the ground before performing maintenance on the DSLC, wearing natural fiber clothing while performing maintenance on the controller, and maintaining the DSLC. And keep plastic, vinyl, and styrofoam materials as far away from controllers, modules, and work areas as possible.
