关于LSU-122DG 阿尔斯通驱动器的一些信息：

LSU-122DG 驱动器的描述：

LSU-122DG 是一种变负载分配单元，属于 DEIF 系列（uni-line）的继电器，用于保护和控制发电机。该单元用于在多个发电机之间共享发电机组的无功负载。每个发电机应用一个单元。

安装和启动说明：

LSU-122DG 设计用于面板安装，可以安装在35毫米 DIN 导轨上，或通过两个4毫米螺丝安装。重量约为0.75公斤。设计使得该单元可以靠近其他 uni-line 单元安装，但确保该单元与其他继电器/单元的顶部和底部之间至少有50毫米的距离。多个继电器安装在同一导轨上时，DIN 导轨必须始终水平放置。

连接图：

所有电压输入可能由一个2A保险丝保护。该继电器对静电放电（ESD）有保护，并且在安装继电器期间不需要进一步的特殊保护。

应用示例：

产品详情：

DEIF 的负荷分配装置通过电子电位计（EPQ96-2 或 EPN110DN）在发电机和调速器接口之间提供多种方式的负荷分配。适用于柴油发电机和燃气发电机的控制，例如，它们可以独立模式（执行频率控制）或与其他功率单元并联模式（执行频率和功率控制）控制功率单元。该装置内置功率和频率传感器，可连接外部设备。恒定功率或同步模式也是可能的。速度控制由两个继电器进行。

变体：

LSU-112DG - 频率和功率控制

LSU-113DG - 频率和功率控制，使用 -P>

LSU-114DG - 频率和功率控制，带启动/停止

LSU-122DG - 反应的，U 和 Q 控制

Some information about the LSU-122DG Alstom drive:

Description of LSU-122DG drive:

The LSU-122DG is a variable load distribution unit belonging to the DEIF series (uni-line) relays used to protect and control generators. This unit is used to share the reactive load of a generator set between multiple generators. Each generator applies one unit.

Installation and startup instructions:

The LSU-122DG is designed for panel mounting and can be mounted on a 35 mm DIN rail or via two 4 mm screws. It weighs about 0.75 kg. The design allows the unit to be installed close to other uni-line units, but ensures that there is at least 50 mm between the unit and the top and bottom of the other relays/units. When multiple relays are mounted on the same rail, the DIN rail must always be placed horizontally.

Connection diagram:

All voltage inputs may be protected by a 2A fuse. The relay is protected against electrostatic discharge (ESD) and requires no further special protection during relay installation.

Application examples:

See the "uni-line Application Notes" for more information.

Product Details:

DEIF's load distribution devices provide multiple modes of load distribution between the generator and governor interfaces via electronic potentiometers (EPQ96-2 or EPN110DN). Suitable for the control of diesel and gas generators, for example, they can control the power unit in independent mode (perform frequency control) or in parallel mode with other power units (perform frequency and power control). The unit has built-in power and frequency sensors and can be connected to external devices. Constant power or synchronous modes are also possible. Speed control is performed by two relays.

Variant:

LSU-112DG - Frequency and power control

LSU-113DG - Frequency and power control, using -P>

LSU-114DG - Frequency and power control with start/stop

LSU-122DG - Reaction, U and Q control
